A FOURTH unexploded bomb found near Britain’s Hinkley Point C nuclear site!

Bridgwater Mercury 16th Sept 2017, A FOURTH unexploded bomb thought to date back to the Second World War hasbeen found in the Bristol Channel not far from Hinkley C. Watchet
Coastguard say the 250lb device is partially detonated and is advising
vessels in the area to proceed with caution and stay at least 500m away
from the site. It is likely the device will be dealt with via a controlled
detonation later today (Saturday, September 16).
This is the fourth such device that has been found in the past two months, but EDF, who are
building a jetty for Hinkley C off the coast near Stogursey, say it is
normal practice to check the seabed before construction activity starts on
any marine project.

Mystery seismic energy release following North Korea nuclear test

Seismologists stumped by mystery shock after North Korean nuclear test, Nature
A second jolt felt minutes after this month’s detonation continues to confound researchers.
 David Cyranoski, Eight-and-a-half minutes after North Korea set off a nuclear bomb on 3 September, a second burst of energy shook the mountain where the test had just occurred. More than a week later, researchers are still puzzling over what caused that extra release of seismic energy — and what it says about North Korea’s nuclear-testing site, or the risks of a larger radiation leak. Monitoring stations in South Korea have already picked up minute levels of radiation from the test.

A number of theories have emerged to explain the second event, ranging from a tunnel collapse or a landslide to a splintering of the rock inside Mount Mantap, the testing site. But seismologists can’t agree and say that they may not get enough evidence to pin down the cause.

“This is an interesting mystery at this point,” says Göran Ekström, a seismologist at Columbia University in New York City.   The nature of the first seismic signal is clearer because it matches the profile of a bomb blast. The US Geological Survey (USGS) determined the magnitude of the seismic event associated with the nuclear explosion at 6.3, whereas the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) in Vienna calculated it at 6.1 on the basis of a separate analysis. The explosion was many times the size of past North Korean tests and was the largest seismic signal from a nuclear test ever detected by the international network of seismic monitoring stations used by the CTBTO.

The second event came 8.5 minutes later and registered as magnitude-4.1, reported the USGS. The agency suggested that it was associated with the test and may have been a “structural collapse”. The possibility that the smaller shock was caused by a tunnel collapse inside the testing site has dominated discussion in the media. But Paul Earle, a seismologist at the USGS, told Nature that was just one possibility that was raised in the immediate aftermath of the explosion. The USGS, he said, was “basing that on previous nuclear tests of comparable size that had a collapse”.

Possible signs of a collapse are visible on satellite images taken of the testing site, according to an analysis released on 12 September by 38 North, a partnership of the US-Korea Institute and the Johns Hopkins School of Advanced International Studies in Washington, DC.

But the seismic signal doesn’t match what would be expected from a collapse, says Lianxing Wen, a geophysicist at the State University of New York at Stony Brook. A collapse would produce mostly vertical movement of rock, but his own unpublished work suggests that the seismic clues point to a large horizontal movement as well, something he says would be more consistent with a landslide.

Sliding scale

Although the satellite data do show a lot of landslides on Mount Mantap, other researchers argue that they could not have caused the magnitude-4.1 event. Much larger landslides, such as at Bingham Canyon mine in Utah in 2013, haven’t produced seismic signals close to that size, says Ekström.  He also argues that the seismic signals he has seen do not match the pattern expected from a landslide……https://www.nature.com/news/seismologists-stumped-by-mystery-shock-after-north-korean-nuclear-test-1.22618

Former Nevada nuclear site experiencing wildfire

“It’s being fought by security site fire crews, with help from a helicopter able to detect any aerial release of radiation.” Like monitoring is going to help or they’re going to share their data. Not a peep about the radiation numbers during the fires in and around Los Alamos even though they were “monitoring” – comment by  Helen Helen Mary Caldicott and Henry Peters

Wildfire burning in former Nevada nuclear site, Daily Mail UK By Associated Press 1 September 2017 RENO, Nev. (AP) – The Latest on wildfires burning across the western United States
An official says firefighters are battling a lightning-sparked wildfire in a remote part of the vast former national nuclear proving ground north of Las Vegas. Nevada National Security Site spokeswoman Tracy Bower said Thursday that the fire covers almost 4 square miles (10 square kilometers) in the western part of what used to be the Nevada Test Site.

More than 1,000 nuclear detonations occurred at the 1,360-square-mile (3522-square-kilometer) secure federal reservation from 1951 to 1992. It now hosts non-nuclear experiments and safety training.

Bower didn’t have immediate information about the exact location of the fire or what tests may have taken place in the burn area in the past.

She says the fire started Monday and isn’t considered a threat to people or buildings.

It’s being fought by security site fire crews, with help from a helicopter able to detect any aerial release of radiation. : http://www.dailymail.co.uk/wires/ap/article-4842050/The-Latest-Wildfire-burning-former-Nevada-nuclear-site.html#ixzz4s81RPn00

A WW2 unexploded bomb found near to Hinkley nuclear station – for the 3rd time!

Third WWII bomb found in Bristol Channel near Hinkley Point, Guardian 30th Aug 2017  Half-mile exclusion zone set up near nuclear plants after third unexploded device discovered in as many weeks

A half-mile (1km) exclusion zone has been set up in the Bristol Channel near the Hinkley Point nuclear power stations after a third unexploded second world war bomb was discovered in as many weeks.

Bomb disposal experts will carry out a controlled explosion on the 250lb (113kg) ordnance on Wednesday, two miles north-west of the power plants. HM Coastguard has set up an exclusion zone around the unexploded device and warned ships to avoid the area.

The bomb was reported in the early hours of Wednesday by a diving team from the Hinkley Point plant. They were clearing the seabed for intake and outtake pipes for cooling water for the reactors on the Hinkley Point C plant.

It is the third suspected second world war bomb to be found in the Bristol Channel in the past three weeks. An EDF source conceded that divers could find more unexploded ordnance before the exercise to clear the area was completed, as the channel was used as a former army training range. The project to clear the seabed is expected to take several more weeks.   https://www.theguardian.com/world/2017/aug/30/third-wwii-bomb-bristol-channel-near-hinkley-point-nuclear

UK Royal Navy detonates the second bomb found in the sea near Hinkley Point.

 West Somerset Free Press 22nd Aug 2017, A ROYAL Navy bomb squad was in action for the second time in eight days last Wednesday as it detonated another bomb found in the sea near Hinkley
Point. The 250lb Second World War device, discovered by divers checking the
seabed before the construction of cooling water tunnels for the power
station, was half the size of the bomb that Navy experts successfully
detonated on August 8, as reported in last week’s Free Press. As before,
the bomb was ringed by a one kilometre exclusion zone and the area was
off-limits for shipping for 24 hours. http://www.wsfp.co.uk/article.cfm?id=108283&headline=Second%20bomb%20found%20near%20Hinkley§ionIs=news&searchyear=2017

Mysterious forest explosion a year ago- now revealed to have been a failed Russian missile launch

Mysterious forest flash was failed test of new nuclear missile https://thebarentsobserver.com/en/security/2017/08/giant-forest-flash-was-failed-test-new-nuclear-missile

Remember the huge circular impact zone in the forest outside Arkhangelsk last August? Well, now it is confirmed to be the first test launch of Russia’s new Yars-M intercontinental ballistic missile.

Locals in the village of Ust-Pocha in the Pinega district (Arkhangelsk Oblast) were all shocked by two huge explosions on August 25th last year. The powerful blasts could be heard from several tens of kilometers away and caused strong vibration in their houses.

When walking into the forest, one and a half kilometers from the village, people were met by a scene that could have been from the James Bond movie GoldenEye. Trees were scattered in a circle several hundred meters in diametre.

There was no meteor or metal scrap to be found in crater in the middle. No visible burns. Some Russian media reported it could have been a rocket launch that failed. Plesetsk, the northern cosmodrome, lies only some 170 kilometers, and locals in the villages in the Pinega district are used to see rockets launched from Plesetsk flying into orbit over their houses.

But, strangely enough, no rocket launched were listed that day. Officials from Plesetsk didn’t either provided any information afterwards. Until now, nearly a year later.

In July, the third book in the serie «Russia’s Northern Cosmodrome» were presented, and there, in the list of launches from Plesetsk, a short line reviled it all; on August 25th, 2016, the very first test-launch of the Yars-M ICBM took place.

The information was soon republished at a Russian discussion blog-site for strategic and tactical nuclear weapons. Pavel Podvig, an independent analysts who runs the research project «Russian Nuclear Forces» picked up the info and linked it to last year’s infamous forest flash outside Arkhangelsk.

Yars-M is a smaller and lighter version of the Yars intercontinental ballistic missile. Making it smaller, the Russian strategic missile forces can base the new missile into the new so-called Barguzin ICBM-carrying railway missile train, like Deputy Prime Minister DMitry Rogozin announced would be developed by 2018, RIA Novosti reported last month.

According to several British media, like the Daily Mail, a successful test-launch of the Yars-M missile was done from Plesetsk in early November, just over two months after the launch of the missile that crashed in the forest 170 kilometers from the launch-pad in August.

Protestors against nuclear dumping injured in police attack in northeast France

French Police Attack Protest Against Nuclear Waste Site http://www.telesurtv.net/english/news/French-Police-Attack-Protest-Against-Nuclear-Waste-Site-20170816-0012.html 16 August 2017 Protest organizers said 36 people were injured, with six gravely hurt.

Police in northeast France used water cannons and fired tear gas and stun grenades Tuesday against demonstrators protesting plans to store nuclear waste at an underground site.

The issue has been raging for years as the waste is the dangerous long-term by-product of France’s extensive nuclear energy program.

Around 300 protesters took part in the demonstration in Bure, a commune in the Meuse department, against plans to store highly radioactive waste 500 meters underground.

Protest organizers said 36 people were injured, with six gravely hurt in the clashes, while the local prefecture said at least three demonstrators had been injured, according to calls to emergency services.

The protest was one in a series to try to block the waste site. France’s Environment Minister Nicolas Hulot has said he needs more information before he gave his position on the project.

Earlier this month, the Nuclear Safety Authority said it had “reservations” about the project, known as Cigeo, citing uncertainty about the potential danger from highly inflammable material in the case of rising temperatures.

In July, the National Agency for the Management of Radioactive Waste said construction of the storage site would start in 2022 at the earliest.

A bomb found near the Hinkley C nuclear project – for the SECOND time

Second World War bomb found off coast of Hinkley Point http://www.somersetlive.co.uk/news/somerset-news/second-world-war-bomb-found-335854    Watchet Coastguard shared a notice on their Twitter account telling people to stay clear of the cordon, BY RUTH OVENS 16 AUG 2017, 

A 250 pound bomb has been found off the coast of Hinkley Point.

Mariners are being advised to avoid the area of the bomb which is thought to date back to the Second World War.

 Watchet Coastguard shared a notice on their Twitter account telling people to stay clear of the cordon.

Hinkley Point C Harbour Authority have shared the following notice:

“Mariners are advised that a 250 pound bomb thought to date from Second World War has been discovered in position Latitude 51’13.43’ North, Longitude 003’09.22 West. This position is approximately six cables south-east from Gore Bouy. “Vessels within this area are requested to proceed with caution, maintain minimum safe distance of 500 metres and keep continued watch on VHF channel 16.”

Earlier this month, the Explosives Ordnance Disposal (EOD) team destroyed a piece of ordnance that was found in the sea off the West Somerset coastline. A 1km exclusion zone was put in place after the large piece of ordnance was found 2.5nm off Lilstock Range in the Bristol Channel on August 8.

Multiple violations found at Washington State’s nuclear power plant

Multiple violations found at state’s nuclear power plant, Susannah Frame, KING   August 10, 2017 The Washington State Department of Health (DOH) last month suspended indefinitely the shipment of radioactive waste from the state’s sole nuclear power plant.

Internal documents obtained by the KING 5 Investigators reveal that the Columbia Generating Station, operated by the publicly owned Energy Northwest, made repeated errors in its shipping of radioactive waste, in violation of state and federal regulations, dating back to 2014.

“There have been multiple deficiencies with the shipments of radioactive waste which has resulted in noncompliance with Federal, US Ecology, and State of Washington requirements,” wrote Robby Peek, Energy Northwest Quality Services supervisor in a July 26 interoffice memo.

Peek characterized the problems as “significant” and wrote the pattern of errors has led to a “loss of regulatory confidence.”

“Additionally, incorrect details within the shipping manifest can increase risk to the health and safety of the public,” wrote Peek.

The most recent event caused the DOH to revoke the plant’s shipping rights for the third time in the last three years.

A July 26 letter from the DOH to Energy Northwest outlines what led to the temporary ban. Inspectors at the state’s low level radioactive waste dump found a July 20 shipment of waste was far more radioactive than what was listed on the shipping manifest.

“Inspections of your shipment revealed (violations) of the US Ecology Radioactive Materials license…and the Washington Administrative Code,” wrote Kristen Schwab, DOH Office of Radiation Protection waste management supervisor. “Because of the nature of the violations found in this shipment, authorization to use the commercial low-level radioactive waste disposal site by Energy Northwest has been suspended indefinitely.”……. http://www.king5.com/news/local/multiple-violations-found-at-states-nuclear-power-plant/463541510

Unexploded WW2 bomb found near Hinkley Point C nuclear power project

BBC 8th Aug 2017, A bomb believed to be from World War Two has been found in the Bristol
Channel near Hinkley Point nuclear power station. The 500lb device was
discovered 2.5 nautical miles from the coast, about 8m below the surface.

Divers conducting a survey for the construction of the new power station
found the ordnance on Monday. It was destroyed in a controlled explosion at
about 15:00 BST on Tuesday. The “unusual” ordnance was found off Lilstock
Range, just west from Steart point and Bridgwater in Somerset.

The coast around Lilstock was used as part of a practice bombing range for the Royal
Navy. EDF Energy said its team of divers made the discovery 8m below the
surface while checking the seabed ahead of the construction of the main
cooling water tunnels for new Hinkley Point C nuclear power station being
built.  http://www.bbc.co.uk/news/uk-england-bristol-40865105

Gas may have ruptured bag at Japan’s nuclear facility

Gas may have ruptured bag at nuclear facility https://www3.nhk.or.jp/nhkworld/en/news/20170721_01/NHK has learned the operator of a nuclear research facility northeast of Tokyo believes a bag containing nuclear fuel materials ruptured last month due to a buildup of gas in it.
The rupture occurred on June 6th at the facility run by the Japan Atomic Energy Agency in Ibaraki Prefecture. Five workers were exposed to plutonium and other radioactive materials.

In the bag was a plastic container that stored nuclear fuel materials. The materials were held together by an adhesive agent to make it easier to use in experiments.

A report compiled by the agency says gas is believed to have been generated when radioactive rays disintegrated the adhesive agent, the polyethylene container, and the molecules of water in the bag.

The agency plans to submit a report to the Nuclear Regulation Authority as early as Friday. It will also conduct further analyses to determine the amount of the adhesive agent and the condition of the nuclear fuel materials when they were inside the container.

America’s NRC to examine safety vulnerabilities, following fire and explosion at Turkey Point nuclear station

Turkey Point: Fire and Explosion at the Nuclear Plant, UCS , DAVE LOCHBAUM, DIRECTOR, NUCLEAR SAFETY PROJECT | JULY 11, 2017The Florida Power & Light Company’s Turkey Point Nuclear Generating Station about 20 miles south of Miami has two Westinghouse pressurized water reactors that began operating in the early 1970s. Built next to two fossil-fired generating units, Units 3 and 4 each add about 875 megawatts of nuclear-generated electricity to the power grid.

Both reactors hummed along at full power on the morning of Saturday, March 18, 2017, when problems arose.

The Event

At 11:07 am, a high energy arc flash (HEAF) in Cubicle 3AA06 of safety-related Bus 3A ignited a fire and caused an explosion. The explosion inside the small concrete-wall room (called Switchgear Room 3A) injured a worker and blew open Fire Door D070-3 into the adjacent room housing the safety-related Bus 3B (called Switchgear Room 3B.)

A second later, the Unit 3 reactor automatically tripped when Reactor Coolant Pump 3A stopped running. This motor-driven pump received its electrical power from Bus 3A. The HEAF event damaged Bus 3A, causing the reactor coolant pump to trip on under-voltage (i.e., less than the desired voltage of 4,160 volts.) The pump’s trip triggered the insertion of all control rods into the reactor core, terminating the nuclear chain reaction.

Another second later and Reactor Coolant Pumps 3B and 3C also stopped running. These motor-driven pumps received electricity from Bus 3B. The HEAF event should have been isolated to the Switchgear Room 3A, but the force of the explosion blew open the connecting fire door, allowing Bus 3B to also be affected. Reactor Coolant Pumps 3B and 3C tripped on under-frequency (i.e., alternating current electricity at too much less than the desired 60 cycles per second). Each Turkey Point unit has three Reactor Coolant Pumps that force the flow of water through the reactor core, out the reactor vessel to the steam generators where heat gets transferred to a secondary loop of water, and then back to the reactor vessel. With all three pumps turned off, the reactor core would be cooled by natural circulation. Natural circulation can remove small amounts of heat, but not larger amounts; hence, the reactor automatically shuts down when even one of its three Reactor Coolant Pumps is not running.

At shortly before 11:09 am, the operators in the control room received word about a fire in Switchgear Room 3A and the injured worker. The operators dispatched the plant’s fire brigade to the area. At 11:19 am, the operators declared an emergency due to a “Fire or Explosion Affecting the Operability of Plant Systems Required to Establish or Maintain Safe Shutdown.”

At 11:30 am, the fire brigade reported to the control room operators that there was no fire in either Switchgear Room 3A or 3B.

Complication #1…….

Complication #2…… Complication #3……. Complication #4…..

…….The NRC needs to understand HEAF factors as fully as practical before it can determine if additional measures are needed to manage the risk. The NRC is also collecting information about potential HEAF vulnerabilities. Collectively, these efforts should enable the NRC to identify any nuclear safety problems posed by HEAF events and to implement a triaged plan that resolves the biggest vulnerabilities sooner rather than later. http://allthingsnuclear.org/dlochbaum/turkey-point-fire-and-explosion-at-the-nuclear-plant

Hanford nuclear station has a widlfire, now 85 percent contained

Wildfire partly on Hanford nuclear site is 85 percent contained http://komonews.com/news/local/wildfire-partly-on-hanford-nuclear-site-is-85-percent-contained by Associated Press, 6 July 17RICHLAND, Wash. (AP) – A wildfire burning in part on the Hanford Nuclear Reservation is 85 percent contained and does not threaten any of the site’s nuclear facilities.

The grass and brush fire covers about 35.9 square miles in Yakima and Benton counties.

There are no evacuations or closures related to the fire, which started last Sunday.

Fire officials say a drone aircraft flew over the fire area on Tuesday, temporarily grounding aircraft assigned to fighting the fire.
