Tsunami risk for nuclear reactors on coastlines of India and Pakistan

Nuclear plants in Arabian Sea face tsunami risk  https://phys.org/news/2020-09-nuclear-arabian-sea-tsunami.html, by SciDev.Net, 21 Sep 20,  A major tsunami in the northern Arabian Sea could severely impact the coastlines of India and Pakistan, which are studded with sensitive installations including several nuclear plants, says the author of a new study.

“A magnitude 9 earthquake is a possibility in the Makran subduction zone and consequent high tsunami waves,” says C.P. Rajendran, lead author of the study, which was published this September in Pure and Applied Geophysics.

“Our study is a step towards understanding the tsunami hazards of the northern Arabian Sea,” says Rajendran. “The entire northern Arabian Sea region, with its critical facilities, including nuclear power stations, needs to take this danger into consideration in hazard perceptions.”

Atomic power stations functioning along the Arabian Sea include Tarapur (1,400 megawatts) in India’s Maharashtra state, Kaiga (being expanded to 2,200 megawatts) in Karnataka state and Karachi in Pakistan (also being expanded to 2,200 megawatts). A mega nuclear power plant coming up at Jaitapur, Maharashtra will generate 9,900 megawatts, while another project at Mithi Virdi in Gujarat may be shelved because of public opposition.

Nuclear power plants are located along coasts because their enormous cooling needs can be taken care of easily and cheaply by making using abundant seawater.

“Siting nuclear reactors in areas prone to natural disasters is not very wise,” says M.V. Ramana, Simons Chair in Disarmament, Global and Human Security and Director, Liu Institute for Global Issues, University of British Columbia, tells SciDev.Net. “In principle, one could add safety systems to lower the risk of accidents—a very high sea wall, for instance. Such safety systems, however, add to the cost of nuclear plants and make them even more uncompetitive when compared with other ways of generating electricity.”

“All nuclear plants can be subject to severe accidents due to purely internal causes, but natural disasters like earthquakes, tsunamis, hurricanes, and storm surges make accidents more likely because they cause stresses on the reactor that could lead to some failures while simultaneously disabling one or more safety systems,” says Ramana, who has worked extensively on nuclear energy.

Rajendran and his team embarked on the study after noticing that, compared to peninsular India’s eastern coast, tsunami hazards on the west coast were under-recognized. This despite the 8.1 magnitude earthquake that occurred in the Makran subduction zone in 1945.

The study relies on historical reports of a major disturbance that struck the coast of western India in 1524 that was recorded by a Portuguese fleet off Dabhol and the Gulf of Cambay, and corroborated by geological evidence and radiocarbon dating of seashells transported inland which are preserved in a dune complex at Kelshi village near Dabhol.

Modeling carried out by the team produced results suggesting that the high impact in Kelshi could have been generated by a magnitude 9 earthquake sourced in the Makran subduction zone during the 1508 —1681 period, says Rajendran. Subduction zones occur where one tectonic plate slides over another, releasing seismic energy.

As per radiocarbon dating of the shells, the inundation may have occurred during 1432—1681 and overlaps the historical reports of major sea disturbances in 1524 that were recorded by a Portuguese fleet of 14 ships led by Vasco da Gama, the man who discovered the sea-route between India and Europe.

A future mega-tsunami originating in the Makran subduction zone could not only devastate the coasts of Iran, Pakistan and Oman but also the west coast of India, says Rajendran, adding that alternate offshore quake sources are yet to be identified in the Arabian Sea.

The larger Indian Ocean features another tectonically active tsunamigenic source—in the Andaman-Sumatra region where the devastating 2004 Asian tsunami occurred. “The next tsunami, after our experience in 2004, will likely be on the west coast,” says Rajendran.

The 2004 tsunami claimed more than 250,000 lives and devastated the beaches of Indonesia, Thailand and Sri Lanka, and claimed lives as far away as Yemen, Somalia and South Africa. Significantly, an atomic power plant at Kalpakkam, on the coast of India’s south-eastern, Tamil Nadu state, was flooded.

Earlier studies, such as the one published in 2013 in Geophysical Research Letters, have indicated that tsunamis, similar in magnitude to the one caused by the 2004 Sumatra earthquake, could occur at the Makran subduction zone where the Arabian plate is subducting beneath the Eurasian plate by about 1.5 inches per year.

According to the 2013 study, the Makran is a wide-potential seismogenic zone that may be capable of generating a very significant (greater than 8.5 in magnitude) tsunamigenic earthquake that poses risks to the coastlines of Pakistan, Iran, Oman, and India.

Vinod Menon, a founder member of India’s National Disaster Management Authority tells SciDev.Net that the new study “raises pertinent questions on the seismic and tsunamigenic risks from a potential rupture of the Makran subduction zone.”

“The tsunami risk and vulnerability of the west coast has not received adequate attention in spite of a history of occurrence in the past as curated by the authors as well as previous studies,” says Menon, who adds that it is worth noting that there are far more sensitive installations around the northern Arabian Sea than in the Andaman-Sumatra region.

Ramana says that such studies serve as a warning against the risks and costs of setting up nuclear power plants in seismically vulnerable areas. “A decade after the 2011 disaster in Fukushima, the prefecture retains radioactive hotspots and the cost of clean-up has been variously estimated to range between US$20 billion and US$600 billion.”

Nuclear waste transport , and legal action – UK

CORE Briefing 17th Sept 2020, With both the Pacific Egret and Grebe back in Barrow docks after their stints at Falmouth and Rosyth ship yards for safety and fitness Certification checks, return high level nuclear waste shipments from Sellafield to Germany will resume this autumn. A shipment due to take place in March this year was cancelled and its transit permit withdrawn by Federal Minister of the Interior Horst Seehofer to avoid the risk of Covid 90 infection to 6000 federal police officers needed to guard its safety.
But In a letter to Friends of the Earth Hesse on 15/9/20 the Federal Office for Nuclear Safety and Nuclear Waste Disposal ordered the immediate re-issuing of the transport permit for a new date this autumn. The group has announced it will fight this decision in court. A total of 3 shipments containing seven castors containing highly radioactive nuclear waste resulting from German spent fuel reprocessing at Sellafield will travel by rail along the West Cumbrian coast to the port of Barrow in Furness, loaded onto one of the INS (NDA subsidiary) ships and carried to the German port of Nordenham. From there it will travel by rail to the interim storage facility at Biblis nuclear power plant.

Due to numerous safety issues with storage of high-level waste at Biblis, the BUND Hessen has filed a lawsuit saying it will take legal action against the now reinstated transport licence. With last Sunday’s local German elections in North Rhine-Westphalia, the Greens achieved a record result with 20% and there will be green mayors in the former capital Bonn, Münster and the anti-nuclear stronghold Aachen.

Relicensing Turkey Point nuclear station – a striking example of a dangerous action in climate change times

Even more bizarre, under current regulations, nuclear operators can take up to 60 years to decommission a closed plant. Decommissioning is the process by which a nuclear reactor is dismantled to the point that it no longer requires radiation protection measures. In the case of Turkey Point, if the reactors stay online beyond 2050, decommissioning could extend into the next century, when sea level rise due to climate change is predicted to inundate southern Florida.
Nuclear plants and climate change don’t mix. While proponents of nuclear energy often argue that nuclear power is a necessary tool against the climate crisis, nuclear power itself is at risk from climate change.
In this process, major safety and environmental issues have been declared off limits by a regulatory sleight of hand known as the Generic Environmental Impact Statement. In 1996, the Nuclear Regulatory Commission drafted a generic analysis of those environmental impacts it deemed would be the same for every nuclear reactor license renewal. Because the commission determined that this statement addresses a set of designated “generic” impacts, and put the result of that analysis in law, individual applicants for renewed nuclear reactor licenses are not required to address those safety and environmental issues. Rather, applicants only need to supplement that generic impact statement with an analysis of issues categorically designated “site-specific.”  
With climate change, aging nuclear plants need closer scrutiny. Turkey Point shows why. https://thebulletin.org/2020/09/with-climate-change-aging-nuclear-plants-need-closer-scrutiny-turkey-point-shows-why/ By   Caroline Reiser , September 14, 2020

Last December, two nuclear reactors at Florida’s Turkey Point Nuclear Generating Station, located 25 miles south of Miami, became the first reactors in the world to receive regulatory approval to remain operational for up to 80 years, meaning reactors that first came online in the 1970s could keep running beyond 2050.

The ages of the Turkey Point reactors are not unusual; of the 95 reactors currently licensed to operate in the United States, only five are less than 30 years old, while more than half are 40 or more years old. The Turkey Point reactors are a bellwether, just the first of possibly many aging nuclear reactors that will seek permission to stay online well into the middle of the century. Not long after the December decision, in March 2020, the US Nuclear Regulatory Commission granted two more reactors, located in Pennsylvania, the same extensions that it gave Turkey Point.

In pursing these extensions, the US commercial nuclear industry and its supporters collide with the realities of the aging US nuclear fleet and climate science projections. Existing safety and environmental requirements fail to provide the oversight necessary to ensure communities and the environment are protected. As nuclear reactors receive permission to operate for twice as long as originally envisaged, and in a world that, because of climate change, is drastically different from the one they were built for, the insufficiency of the existing regulatory framework is daunting.

A 40-year lifespan? At the beginning of its commercial nuclear power program, the United States designed and licensed reactors with a 40-year projected lifetime. Once the 40-year license is set to expire, regulations require the reactor owner to apply for a renewed license in order to continue operating for an additional 20 years. What the regulations don’t make clear, however, is the number of times a reactor license can be renewed. What Turkey Point received last year was not its first, but its second extension—what regulators call a subsequent renewed license. Continue reading

The coronavirus pandemic and the increased safety risks for nuclear reactors

Nuclear Alert: NRC & Nuke Safety In the Time of COVID-19    https://www.fairewinds.org/demystify/nuclear-alert-nrc-amp-nuke-safety-in-the-time-of-covid-19 September 14, 2020  By The Fairewinds Crew

First off, we would like to preface this by saying that the world simply cannot afford a meltdown or nuclear disaster on top of the already traumatic times wrought by Pandemic 2020.

Did you know that nuclear plants close for scheduled refueling every 18-months, meaning that 1/3 of the operating reactors are off-line each spring and fall? For the record, more than three dozen reactors had planned to do so in Spring 2020. The Nuclear Regulatory Commission (NRC) defines this rather temporary closing as an outage. During these outages, used-up nuclear fuel is replaced, and critical safety inspections are performed.

You may remember, that in early May, Maggie wrote extensively about the numerous safety risks to all of us if the nuclear industry continued operating these reactors during the COVID-19 Pandemic without implementing critical safety protocols and procedures. Along with 86 other organizations from all over the U.S., Fairewinds Energy Education nonprofit cosigned a letter to Vice President Pence and the COVID-19 Task Force detailing significant safety risks that must be addressed. You can read more about that letter and the increased safety hazards here. To date, we have received no response!

When the COVID-19 Pandemic began in late February, atomic reactor operators and owner corporations begged the NRC for special exemptions from regulatory requirements to implement critical safety and security inspections for up to two years! And, in an extreme example of regulatory capture, the NRC has approved all the corporate requested safety inspection delays, handing them out like candy to eager Trick-or-Treaters on Halloween! We know you have heard this before from the Crew at Fairewinds Energy Education, however, let us emphasize again that the federal laws [called statutes] that authorize the NRC, chartered it to protect ‘public health and safety’. Letting the industry continue to ignore critical safety inspections risks public health and safety!

During the past decade, the success in the growth of renewables has caused the nuclear industry to fight tooth and nail to keep operating even though nuclear power plants are much more expensive to operate than sustainable energy sources, and nukes charge much higher rates to consumers. Additionally, the risk of a disaster or other calamity has increased dramatically due to the old age of all current U.S. operating reactors. Instead of moving to solar and wind and shutting down these decrepit reactors, the energy and utility corporations are trying to reduce their higher operating costs by laying off employees and pushing the people remaining to work harder to save money and continue stockholder profit earnings.

Rather than slowing down these Spring refueling outages and allowing more time for inspections and repairs due to the extra burden the COVID-19 Pandemic has put on their employees and contractors, America’s nuclear monopoly has decided to risk ‘public health and safety’ – you remember what the federal law states – by reducing the amount of safety inspections the staff at each reactor was scheduled to perform. We agree that squeezing three or more people into a confined space for an inspection could be a recipe for COVID-19 transmission. However, slowing the inspection down and using fewer people at a time means having the reactor offline [shutdown] for a longer amount of time. In other words, the truth is that any operating schedule delay reduces each corporation’s profits.

Most atomic power reactors earn $1Million dollars in revenue every day. In addition, vice presidents, plant managers, and other corporate functionaries are on special bonus plans equivalent to between 40 and 70% of their salaries in a special year-end bonus. Such huge sums create a unique incentive for nuclear corporate executives to keep the outages as short as possible. When a vice president earns about $500,000, they will receive a $350,000 year-end bonus for meeting corporate goals, especially a short outage. We tend to notice that bonuses of that size cloud one’s judgment. Furthermore, we are reminded of Upton Sinclair when he so aptly said, “it is difficult to get a man to understand something, when his salary depends on his not understanding it.”

Is the risk of a disaster and a major radiation release to the surrounding community worth the extra millions of dollars earned by the corporate owner for starting these reactors up too soon? We don’t believe so.

Despite there being an abundance of available electricity without even using the atomic chain-reaction, the nuclear power operators and their corporate owners as well as the nuclear industry lobby are claiming that delayed testing will not cause a disaster and no nearby communities will be damaged or deal with the radioactive exposure to its residents.

Safety risks obviously increase because critical inspections are being delayed.

A powerful message on the seismic dangers in Hinkley Point C nuclear construction. It would be cheaper to pull out now.

Radiation Free Lakeland 12th Sept 2020, Seismic Warnings – if not now when will the Government Scrap Hinkley C? This week there was yet another earthquake recorded in the Bristol area. It was small but significant, contributing to the well documented seismic activity of the area. If eyewatering costs, long delays, a mental and physical health crisis among the employees building Hinkley Point C are not enough to scrap this hubristic nuclear new build plan then the seismic warnings should be.

This insane project next to operational reactors has seen the geological stresses of the biggest pours of concrete in the UK
alongside three huge tunnels being bored below the seabed. German based multi-national company Herrenknecht built the hugely expensive tunnel boring machines which will be dumped under the Bristol Channel once done.

A total of 38,000 concrete segments are needed to support the tunnels, which would transfer 120,000 litres of water per second for the new nuclear plant when finished. The Bristol area is seismically active so to put increased geological stress deliberately in the vicinity of existing nuclear reactors is the kind of hubris that disaster movies are made of.

Scrapping Hinkley C now and paying off the developers would be far cheaper and far safer than continuing down this route to nuclear disaster.

Unmarked ?nuclear convoy with strong military police guard sweeps through Bristol city centre

Watch moment unmarked ‘nuclear’ convoy swept through Bristol city centre, Unconfirmed reports suggest it was a nuclear convoy, Bristol Post By

Tristan CorkSenior Reporter 12 SEP 2020  

This is the moment an unmarked military and police convoy stopped the traffic and stunned drivers and commuters as it swept through the city centre of Bristol this week.

The 14-vehicle convoy was captured on camera as it held up traffic on a main road into Bristol, and then headed out of the city on the M32.

The moment it came down the A37 Wells Road in Totterdown and joined the A4 Bath Road in a wail of sirens was captured by one surprised driver as she was waiting in her stationary car on the other side of the road.

The convoy began with a military police 4×4 car and then went on to include two police cars, three large police vans, another police 4×4, three large army people carriers and what appeared to be the subject of the guard of the convoy – four large LGV lorries with large unmarked containers on the trailers.

The brief video of the convoy was posted on social media within minutes of being spotted at around 7.50am on Wednesday, September 9 this week, and prompted a range of speculation as to what exactly was going on.

There was speculation that the convoy was operated by the AWE, the Atomic Weapons Establishment, an organisation which handles all the nuclear fuel for submarines and material for Britain’s nuclear weapons.

The AWE is based at Aldermaston, at a base just the other side of Newbury in Berkshire. People commenting on the video, which went viral on Facebook, said they had seen many similar convoys around that area, but they usually took place in the middle of the night so did not attract attention……… https://www.bristolpost.co.uk/news/watch-moment-unmarked-nuclear-convoy-4510383

Dominion Energy has filed to keep nuclear station in Virginia going for 80 years!

Dominion files to keep Virginia’s North Anna nuclear plant operating 80 years, Utility Dive, 9Sep 20, 
Dominion Energy announced on Friday it has filed with the U.S. Nuclear Regulatory Commission (NRC) for a 20-year extension of its license to operate two generating units at the North Anna nuclear power plant in Louisa County, Va.

North Anna Units 1 and 2 are currently licensed to operate through 2038 and 2040, having received original licenses in 1978 and 1980, respectively. If renewed, the combined 1.9 GW units would be able to generate carbon-free power until 2058 and 2060, Dominion said………..

More reports of drones flying near Paolo Verde nuclear power plant, and others, and over spent nuclear fuel storage sites

Dozens More Mystery Drone Incursions Over U.S. Nuclear Power Plants Revealed, Forbes,    David Hambling– 7 Sept 20, Forbes recently described how a swarm of drones flew in a restricted area at Palo Verde Nuclear Power Plant on two successive nights last September. A new cache of documents obtained under the Freedom of Information Act (FoIA) reveals how 24 nuclear sites suffered at least 57 drone incursions from 2015 to 2019 – and Palo Verde itself was overflown again in December, despite new security measures.

The documents were obtained by from the U.S. Nuclear Regulatory Commission by Douglas D. Johnson on behalf of the Scientific Coalition for UAP Studies (SCU). The SCU’s main interest is in anomalous aerospace phenomena, more commonly known as UFOs, but Johnson uncovered a series of incidents involving something less exotic but potentially more threatening: commercial drones.
In the September incidents, a swarm of five or six large drones flew over Unit 3 nuclear reactor at Palo Verde in Arizona for about eighty minutes, a length of time which suggested they were carrying out a thorough survey of the site. The documents released at the time referred to a similar incident at Limerick Nuclear Generating Station in Pennsylvania………….
 We do not know how many involved multiple, simultaneous drone flyovers. At the time the list was generated, three of the incidents were listed as ‘Open’ and five ‘Closed Resolved.’ but the overwhelming majority, 49 of them, were ‘Closed Unresolved.’  This indicates that for 85% of the cases the NRC has no idea who the perpetrators are or what they intended, and has given up on finding them………
Limerick had five drone sightings, Perry Nuclear Power Plant in Cleveland, Ohio had six and Diablo Canyon near San Luis Obispo in California had no less than seven separate incidents from December 2015 to September 2018, all of them unresolved. The scale spread and number of intrusions indicate that this is not a local issue, and that the drone overflight may be carried out by a large, coordinated organization.
While most of the sites were nuclear reactors, there were also three drone incursions over spent nuclear fuel storage sites, including Trojan in Oregon and Rancho Seco in California where radioactive waste is stored in steel canisters inside giant concrete casks………..
 While reactors themselves are protected by thick concrete domes able to withstand the impact of a crashing airliner, the above-ground pools in which spend nuclear fuel is stored may be far more vulnerable. A 2011 report by the Institute of Policy Studies noted that over 40,000 tons of highly radioactive waste is stored in pools, many above ground: “some of the largest concentrations of radioactive material on the planet.” These pools are not heavily protected, but are in light structures similar to big-box stores and car dealerships.

A 2003 report noted how vulnerable such pools were to terrorist action, simply by making a hole in the pool to drain out the cooling water and causing the stored fuel to overheat: “We warned that U.S. spent fuel pools were vulnerable to acts of terror. The drainage of a pool might cause a catastrophic radiation fire, which could render an area uninhabitable much greater than that created by the Chernobyl accident.”

Dominion Energy wants to prolong old nuclear reactors – yet again!

Dominion Energy applies for additional 20-year license for its North Anna Power Station nuclear reactor units, By JOHN REID BLACKWELL Richmond Times–Dispatch, 7 Sept 20,  

Dominion Energy, Virginia’s largest utility company, is seeking approval from federal regulators to continue operating its two nuclear reactor units in Louisa County until the years 2058 and 2060.

The Richmond-based company said Friday it has filed an application with the Nuclear Regulatory Commission to renew the North Anna Power Station’s operating licenses for additional 20-year terms.

An approval of the license would allow the company to operate the two reactors beyond a current license extension that was granted in 2003, which enabled the company to run the reactors until 2038 and 2040.

The original licenses for the two North Anna reactor units were granted in 1978 and 1980. As with all U.S. nuclear power plants, the original licenses were granted for 40 years……….

The application has not been made public yet. The NRC staff will conduct an initial review and ensure that protected information such as security-related information is redacted before the application is made public.

Two other nuclear reactor plants in the U.S.—the Turkey Point Nuclear Generating Station in Florida and the Peach Bottom Nuclear Generating Station in Pennsylvania—already have received a second renewal for their reactor licenses. …. https://fredericksburg.com/news/local/dominion-energy-applies-for-additional-20-year-license-for-its-north-anna-power-station-nuclear/article_ad34f155-d01d-5a41-9e05-8a48fe78fcf5.html

More of Britain’s ageing nuclear power stations are likely to close early

Times 6th Sept 2020, More nuclear power stations could close early as EDF wrestles with problems with patching up its ageing plants.  The French power giant owns Britain’s fleet of eight nuclear power stations together with British Gas parent Centrica.
………….  just one new nuclear power station is being built, Hinkley Point C, in Somerset.
EDF said last month that Hunterston B in Ayrshire would close about 15 months earlier than expected, by January 2022, because of cracks in its graphite core. It is also understood to be considering the early closure of at least two more plants — Hinkley Point
B in Somerset and Dungeness B in Kent.
Hinkley Point B is earmarked for closure in early 2023, but EDF is understood to have warned staff in recent days that it may
happen sooner. It is currently not generating while its graphite core is inspected. EDF is due to make a decision on its future in November.
Dungeness B has been offline since 2018, but now there are fears that it may never reopen because of problems with its boilers, which EDF has spent about £100m trying to fix.
Ministers are set to make a decision on whether to fund more nuclear stations within the coming months, with the
publication of a much-delayed energy white paper.

Renewed concerns about safety as dig starts for new shaft at New Mexico’s nuclear Waste Isolatio Pilot Plant

Groups Raise Concerns About New Shaft at US NuclearDump, By Associated Press, Wire Service ContentSept. 4, 2020

Crews at the U.S. government’s underground nuclear waste repository in New Mexico are starting a new phase of a contentious project to dig a utility shaft.  https://www.usnews.com/news/best-states/new-mexico/articles/2020-09-04/groups-raise-concerns-about-new-shaft-at-us-nuclear-dump

ALBUQUERQUE, N.M. (AP) — Crews working at the U.S. government’s underground nuclear waste repository in New Mexico are starting a new phase of a contentious project to dig a utility shaft that officials say will increase ventilation at the site where workers entomb the radioactive remnants of decades of bomb-making.

Officials at the Waste Isolation Pilot Plant said this week that the $75 million project is a top priority and that work will be done round the clock five days a week, with an additional shift on Saturdays. The shaft will eventually span more than four-tenths of a mile and connect to an underground system of passageways.

After reaching a depth of about 60 feet (18 meters), workers now will be drilling small holes and using explosive charges to clear more rock.

Adequate ventilation at the repository has been a big issue since 2014, when a radiation release forced a temporary closure and contamination limited air flow underground where workers dispose of nuclear waste. That prompted the need for a new ventilation system so full-scale operations could someday resume.

The repository is at the center of a multibillion-dollar effort to clean up waste from decades of U.S. nuclear research and bomb-making. Over more than 20 years, tons of waste have been stashed deep in the salt caverns at the southern New Mexico site.

Watchdog groups are raising red flags, saying the work is being done before state environmental officials finish a process allowing the public weigh in and before they have issued a final permit. The New Mexico Environment Department in April granted federal officials temporary approval to start the work as part of a larger request to dig the shaft and passageways.

The Southwest Research and Information Center is among those opposing the project. The group filed legal challenges, saying environmental officials ignored existing regulations, past agency practices and case law when giving temporary approval for contractors to begin working.

The Environment Department has defended its decision, saying the temporary approval was limited to digging the shaft, not using it.

Don Hancock with the Southwest Research and Information Center said state officials essentially foreordained the permit request by allowing work to begin. He also said the state has not provided any technical basis for its decisions and that it reduced the amount of time the public had to comment on the project by delaying the release of a draft permit.

The group has suggested that the shaft, given its size and location, could be used to expand the repository. It says that creates potential for the government to send high-level and commercial waste to the site, along with new radioactive waste that will be generated by manufacturing plutonium cores for the nation’s nuclear arsenal.

Despite congressional limits on the amount and type of waste that can be shipped to the repository, Hancock and other critics said the state’s actions have favored the federal government while limiting the public’s ability to give their input.

The repository’s hazardous waste permit also is up for renewal this year, and more legal wrangling is expected.
