Sendai’s cooling tubes already leaking! But the pro #nuclear hubris goes on!

Japan Sendai Nuclear Restart — The Hubris Alone Is Killing Me, Let Alone the Volcano and Salt Water Leaks, Nuke Pro 21 Aug 15 

http://www.japantimes.co.jp/news/2015/08/21/national/kyushu-delays-increasing-output-sendai-nuclear-plant-cooling-system-problems-detected/#.VddOWJegs8L

I would drop a comment at the link, but I have been banned from Japan Times, so many TIMES that I can’t count.    They have no interest in the truth.
————————————————————————————————————–

Kyushu Electric checked the water quality and confirmed an increase in salt content.

Each condenser has some 26,000 tubes inside that are used to pipe seawater around for cooling. Kyushu Electric suspects that holes have opened on such tubes, causing seawater to enter into the condenser. [diagram below by the author of this article] 

diagram sendai leaks

stock here—You know when you have a heat exchanger, and some of the tubes are already leaking….well 20,000 other tubes are also real close to leaking.    Think San Onofre.   But they say they can “fix it” within a week without shutting down.    Sounds odd to me.     Seems like the real story is the powers that be have decided that hell or high water (Volcanos, Tsunamis, and Salt Leak damned) they are going to not let that plant shut down or they will lose face.

And this is very dangerous way to think.   Perhaps they have 2 sets of heat exchangers, so they can run at 50% whilst one set is completely shut down and worked on.    Regardless, this is a stop gap measure, just like at San Onofre if some tubes are already going, there are many more right behind it.  So these stories will slip out at the weeks go on.

Heat exchangers that can handle salt water are going to be stainless steel at least and ideally titanium. Industry has gotten a lot better at working with titanium in the last few decades.     So those 40 year old heat exchangers at Sendai are probably stainless steel, not at good as titanium.

But in Typical japan Times Fashion, they try to downplay the incident by stating

In Japan, similar problems have occurred about 50 times in the past, but the latest case was the first at the Sendai power plant. In the past, Kyushu Electric experienced two cases at the No. 1 reactor at its Genkai plant in Saga Prefecture in 1997 and 1999.

Classic “don’t worry” it happens all the time.  So the pimps of nuke will  do anything to keep this plant running.    Including putting your life and livelihood at risk………. http://nukeprofessional.blogspot.com.au/2015/08/japan-sendai-nuclear-restart-hubris.html?showComment=1440185210724#c7323011781148838576

China’s race to clear dangerous chemicals from Tianjin explosion site

China warehouse explosion: Tianjin workers race to clear site of deadly chemicals before it rains Fears potential showers could create clouds of toxic gas. Chinese officials face a race against time to clear toxic chemicals from the site of the Tianjin warehouse explosion, amid fears the blast may have released hundreds of tons of toxic gas into the air.

Soldiers have joined rescue workers in gas masks and hazard suits in the port city where the death toll from Wednesday’s massive explosion has risen to 112. Another 95, the majority of whom were firefighters, remained missing.

Officials confirmed the warehouse where the blast occurred was used to house more than 100 tons of sodium cyanide, a potentially deadly substance.

The presence of the chemicals was confirmed by Shi Luze, the chief of staff of the People’s Liberation Army’s Beijing Military Region.

He said workers were trying to clear the area before possible rain showers, which could create toxic gas……..http://www.independent.co.uk/news/world/asia/china-warehouse-explosion-tianjin-workers-race-to-clear-site-of-deadly-chemicals-before-rains-10457786.html

Questions on the causes and effects of the Tianjin explosion

Tianjin explosions ignite barrage of questions, The Age,  China correspondent for Fairfax Media, August 14, 2015  Tianjin: As fatalities continue to mount, so too have questions around the cause, response and potential health effects of the terrifying explosions at a toxic chemicals warehouse that tore through the port city of Tianjin, China, on Wednesday night.

Chinese authorities have dispatched more than 200 military nuclear and biochemical materials specialists to the site of the blast, as well as a team from the International Atomic Energy Agency’s Beijing environmental emergency response centre.

But some 36 hours after the explosions, municipal and environmental officials said they were still unable to determine the specific substances held in the warehouse which likely triggered the blast which killed dozens, injured hundreds, and ignited a fireball so large  it was captured by orbiting satellites.

The owner of the warehouse, Ruihai International Logistics, is a  firm which specialises in handling hazardous cargo, state news agency Xinhua said. It is licensed to handle dangerous and toxic chemicals including sodium cyanide, compressed natural gas, phosphoric acid, potassium nitrate and butanone – an explosive industrial solvent.

“So far, we are not able to provide the detail of type and amount of these dangerous items,” Gao Huaiyou, the deputy director of Tianjin’s work safety administration bureau, said on Thursday. “There is quite a big inconsistency with information provided by the company’s management and their customs declaration.”

Though a pungent smell and visible smog hung in the vicinity of the blast, officials said 17 emergency air monitoring stations indicated air quality in the city remained within a normal range, aided by easterly winds which blew toxic plumes from the fires out to sea.

Readings of cyanide and chemical oxygen demand – a measure of water quality – some three to eight times normal levels were detected near two underground discharge pipes, though officials said the pipes had been sealed off and posed no danger to health or the environment of the surrounding area.

Xinhua said 1000 firefighters and more than 140 fire trucks were struggling to contain the blaze in a warehouse which stored “dangerous goods”.

“The volatility of the goods means the fire is especially unpredictable and dangerous to approach,” it said….http://www.theage.com.au/world/tianjin-explosions-ignite-barrage-of-questions-20150814-gizjw9.html#ixzz3ir0wfaMy

Nuclear experts sent to test China’s Tianjin explosion site

Chemical, nuclear experts testing Tianjin blast site, Aljazeera America,  Military has begun work on the ground in China’s northern port city where two explosions killed at least 55 dead August 14, 2015 China has sent chemical experts into Tianjin to test for toxic gases after a series of deadly explosions.

The team of nuclear and chemical experts is on the ground on Friday in the northern port city of Tianjin, the scene of two massive explosions that have left at least 55 people dead. Seventeen of the dead were from among the more than 1,000 firefighters sent to the mostly industrial zone to fight the ensuing blaze, China’s official Xinhua News Agency reported.

Explosion Tianjin 15

The chemical experts were testing the area for toxic gases, the official news agency Xinhua said, adding that the death toll had climbed to 55, with 701 admitted to hospital.

The team of 217 nuclear and biochemical materials specialists from the Chinese military began work at the site on Thursday.

The explosions at a warehouse for hazardous chemicals in the Chinese port of Tianjin on Wednesday raised questions about the whether the materials had been properly stored. Windows were shattered for miles around by the shockwaves, and the explosions were so big they were seen by satellites in space and registered on earthquake sensors.

Officials in Tianjin said they did not yet know what materials were at the hazardous goods storage facility where the explosions happened, or the cause of the blast.

But the Beijing News reported earlier that according to manufacturers, at least 700 ton of sodium cyanide were at the site, along with other substances, and the poisonous chemical had been detected in sewage samples in the area.

The report was no longer available on the newspaper’s website on Friday………..

ianjin is the 10th largest port in the world by container volume, according to the World Shipping Council, and the seventh-biggest in China. It handles vast amounts of metal ore, coal, steel, cars and crude oil.

Ships carrying oil and “hazardous products” were barred from the port Thursday, the Tianjin Maritime Safety Administration said on its official microblog. It also said vessels were not allowed to enter the central port zone, which is near the blast site.

State media said senior management of the company had been detained, and that President Xi Jinping demanded severe punishment for anyone found responsible for the explosions……..

As is customary during disasters, Chinese authorities tried to keep a tight control over information. Police kept journalists and bystanders away with a cordon about a mile from the site. On China’s popular microblogging platform of Weibo, some users complained that their posts about the blasts were deleted, and the number of searchable posts on the disaster fluctuated, in a sign that authorities were manipulating or placing limits on the number of posts.

The Tianjin government said that because of the blasts it had suspended online access to public corporate records. These records might be used to trace the ownership of Ruihai. It was not clear whether the blackout was due to technical damage related to the explosion. No one answered the phone at the Tianjin Market and Quality Supervision Administration or the Tianjin Administration for Industry and Commerce on Thursday.

Ruihai Logistics said on its website — before it was shut down — that it was established in 2011 and is an approved company for handling hazardous materials. It said it handles 1 million tons of cargo annually……..http://america.aljazeera.com/articles/2015/8/13/at-least-50-dead-and-hundreds-injured-in-chinese-warehouse-explosion.html

Terrorists planned an attack on nuclear weapons base

terrorism-targets-2US Nuclear Weapons Base In Italy Eyed By Alleged Terrorists http://fas.org/blogs/security/2015/07/ghedi-terror/ by   Two suspected terrorists arrested by the Italian police allegedly were planning an attack against the nuclear weapons base at Ghedi.

The base stores 20 US B61 nuclear bombs earmarked for delivery by Italian PA-200 Tornado fighter-bombers in war. Nuclear security and strike exercises were conducted at the base in 2014. During peacetime the bombs are under the custody of the US Air Force 704th Munitions Support Squadron (MUNSS), a 130-personnel strong units at Ghedi Air Base.

The Italian police said at a press conference today that the two men in their conversations “were referring to several targets, particularly the Ghedi military base” near Brescia in northern Italy.

Ghedi Air Base is one of several national air bases in Europe that a US Air Force investigation in 2008 concludeddid not meet US security standards for nuclear weapons storage. Since then, the Pentagon and NATO have spent tens of millions of dollars and are planning to spend more to improve security at the nuclear weapons bases in Europe.

There are currently approximately 180 US B61 bombs deployed in Europe at six bases in five NATO countries: Belgium (Kleine Brogel AB), Germany (Buchel AB), Italy (Aviano AB and Ghedi AB), the Netherlands (Volkel AB), and Turkey (Incirlik AB).

Over the next decade, the B61s in Europe will be modernized and, when delivered by the new F-35A fighter-bomber, turned into a guided nuclear bomb (B61-12) with greater accuracy than the B61s currently deployed in Europe. Aircraft integration of the B61-12 has already started.

Many incidents and near misses in USA’s nuclear reactors

safety-symbol1Flag-USAThe Truth About Nuclear Power – Part 16 Subtitle: Near Misses on Meltdowns Occur Every 3 Weeks Roger E. Sowell, Marina del Rey, California 25 June 15 

This is the second of approximately one dozen articles on nuclear safety, these will (or do) include (1) the relationship between plant operators and the regulatory commission, NRC, and show that safety regulations are routinely relaxed to allow the plants to continue operating without spending the funds to bring them into compliance.  (2) Also, the many, many near-misses each year in nuclear power plants will be discussed.   (3) The safety issues with short term, and long-term, storage of spent fuel will be a topic. (4)  Safety aspects of spent fuel reprocessing will be discussed.  (5) The health effects on people and other living things will be discussed.  The three major nuclear disasters (to date) will be discussed, (6)  Chernobyl, (7) Three Mile Island, and (8)  Fukushima.   (9) The near-disaster at San Onofre will be discussed, and (10) the looming disaster at St. Lucie.  (11)  The inherent unsafe characteristics of nuclear power plants required government shielding from liability, or subsidy, for the costs of a nuclear accident via the Price-Anderson Act.  (12) Finally, the serious public impacts of evacuation and relocation after a major incident, or “extraordinary nuclear occurrence” in the language used by the Price-Anderson Act, will be the topic of an article.   Previous articles showing that nuclear power is not economic are linked at the end of this article.

In the four year period 2010-2013, inclusive, the US nuclear reactors had 70 near-misses.  These occurred in 48 of the 103 reactors.  Some, therefore, had multiple near-misses in the same year.  One plant, Columbia, had 3 near-misses in the same year.  Wolf Creek, and Ft. Calhoun each had one near-miss in three of the four years.  On average, that is 17 near-misses per year, or roughly 17 percent of the reactor fleet.  Put another way, every 3 weeks, another near-miss occurs.  The frequency of near-misses is expected to increase over time, as the aging reactors have more equipment degrade and fail, and new systems are installed that are unfamiliar to the operators.

What is common in these incidents are old and degraded equipment that fails due to improper inspection, replacement equipment that either does not work as expected, or operators are improperly trained, and in one notable case, improperly trained workers left critical bolts improperly tightened on the reactor head.

The most serious incident, in my view, occurred at the Byron Station, Unit 2, in January, 2012, in Illinois.  A complete loss of cooling water at Unit 2 was temporarily replaced with water from Unit 1. Had this been a single-reactor plant, with no operating reactor close at hand, the loss of cooling could have resulted in a partial or full core meltdown, exactly what happened at Fukushima, Japan.  This is completely unacceptable.

Some, the nuclear proponents, will argue that the safety systems are adequate since no meltdowns occurred.  However, the sheer number of serious incidents shows that eventually, another catastrophe will occur.  The US has been lucky, but that luck is likely running out as the plants grow older and more mishaps occur.

Information in these incidents are taken from Union of Concerned Scientists’ series of annual reports, 2010 – 2013, inclusive.  The commentary is my own.  Links to the four (now five) reports are:

USA Department of Energy investigates radiation leaks, and exposure to workers at nuclear sites

DOE probes worker radiation exposure at test site By STEVE TETREAULT REVIEW-JOURNAL WASHINGTON BUREAU WASHINGTON, 19 June 15  — The Department of Energy has launched investigations into two incidents over the past year where workers at the Nevada National Security Site were exposed to potential contamination while conducting nuclear weapons activities.

The episodes took place on June 16, 2014, and Oct. 21, 2014, at the National Criticality Experiments Research Center, the laboratory where the government maintains a substantial stockpile of nuclear material used for research and training.

The department is looking into the circumstances surrounding “losses of contamination control of highly enriched uranium” at the lab, according to Steven Simonson, director of the DOE Office of Enforcement…….

The incidents that prompted the investigation were the latest disclosed missteps by Los Alamos and other outposts in the weapons complex that have come under close scrutiny within DOE and on Capitol Hill.

In May, the Energy Department proposed to fine the operator of the Los Alamos National Laboratory $247,500 after it lost track of classified material that was supposed to have been shipped to the Nevada National Security Site in 2007, but never arrived. The mistake was not detected until five years later.

The New Mexico laboratory also has been faulted in the 2014 release of radiation from the Waste Isolation Pilot Plant that contaminated nearly two dozen workers with low levels of radiation and forced the nuclear waste site to close.

Investigations uncovered violations at the laboratory in how transuranic waste destined for WIPP was packaged and managed……..http://www.reviewjournal.com/news/nevada/doe-probes-worker-radiation-exposure-test-site

Peach Bottom Atomic Power Station radiation leak – source is found

Exelon locates source of radiation leak at Peach Bottom, YDR.com  Officials say the tritium posed no health risk By Brett Sholtis bsholtis@ydr.com @BrettSholtis on Twitter 06/19/2015 

Peach Bottom Atomic Power Station. On April 17, 2015, Exelon detected a level of tritium in excess of the EPA-recommended guidelines. Exelon has located the source of the leak and is taking steps to correct the problem. The Nuclear Regulatory Commission said the tritium poses no health or environmental risk. (FILE — YORK DAILY RECORD/SUNDAY NEWS)

Exelon Corporation has located the source of a water leak that led to elevated levels of tritium in a groundwater well at Peach Bottom Atomic Power Station. Peach Bottom spokeswoman Krista Connelly declined to specify the source of the leak, but confirmed that they have located it………

Paul Gunter, a director at public interest group Beyond Nuclear, said the tritium points to a larger problem of recurring leaks, which the industry doesn’t take seriously. “This is a one-off measurement in one well,” Gunter said. “It doesn’t say how much got out. This is what they detected at that one point.”….http://www.ydr.com/local/ci_28347377/exelon-locates-source-radiation-leak-at-peach-bottom

The emergencies at North Anna Nuclear Power Station

Japan Nuclear Engineer: US reactor at risk of ‘supercriticality’ during recent emergency… “That’s something scary” — Damaged nuclear fuel rods and fuel fragments found at plant, conditions reported as “seriously degraded” (VIDEO)http://enenews.com/japan-nuclear-engineer-reactor-risk-supercriticality-during-recent-emergency-big-spike-neutron-flux-scary-fragments-nuclear-fuel-later-found-plant-conditions-reported-be-seriously-degraded-video?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29

Satoshi Sato, Nuclear Engineer, April 28, 2015 (emphasis added): “I don’t know if you remember, there was the earthquake in 2011 in Virginia. That was a big one… enough to cause vibration to the North Anna reactor resulting in a big spike of neutron flux — or reactor power… and somehow caused the additional radioactivity into the core. So that’s something scary, potentially resulting in a supercriticality.” (IEER: “The neutron spike accompanying a sudden supercriticality can lead to an explosion of the reactor core. It is this sort of event which occurred at the Chernobyl reactor”)

U.S. NRC Event Notification, Aug 29, 2011: EMERGENCY DECLARED… North Anna Power Station declared an Alert [“actual or potential substantial degradation of the level of safety”] due to significant seismic activity… This notification is to report… a condition existed which met the emergency plan criteria but was not declared… Design Basis Earthquake limits may have been exceeded.

U.S. NRC, 2012: Reactor trips at both North Anna 1 and 2, were caused by a “Power RangeHigh Negative Neutron Flux Rate”… four possible causes [were identified] (1) loss of power to the control rod motor generator sets, (2) a dropped control rod, (3) movement of the nuclear instrumentation detectors, and (4) core barrel movement… Analysis included a third-party evaluation of the potential response of the core nucleate boiling… [Physics Forum: “nucleate boiling… reduces the heat transfer capability of the coolant… which leads to even more boiling, etc, until the fuel becomes ‘dry’… the cladding will burn and/or fuel will will melt”]

U.S. NRC email, Sept 2011: RE: North Anna… At this point, it appears that the grippers for several of the control rods deenergized and dropped.

Westinghouse patent: A dropped rod… will initially result in a reduction in the total powergenerated by the core. The reactor will then attempt to meet the load… by increasing powerin the remainder of the core which could lead to local overheating elsewhere in the core.

ASEE 2003 Conference: If a critical reactor is over moderated… the reactor can rapidly reach and exceed the prompt critical condition… Chernobyl started at a low power level, which corresponded to a positive void coefficient.

North Anna Root Cause Evaluation, Oct 2011: The last power decreases prior to the trips were of sufficient magnitude and rate to generate the negative rate trip… Root Cause Evaluation Team has postulated that the major cause of the power oscillations was void defect created by bursts of bubbles… which caused the power increases which followed the power decreases… It is postulated that [as] the seismic waves shake… a large portion of the [fuel] cladding surface is suddenly in the nucleate boiling region [and] causes the bubble burst… [I]t may not be plausible to generate sufficient void to decrease the core power up to 10% [therefore it] can be concluded that the bubble burst theory alone does not explain the magnitude of change [in] Units 1 and 2.

Enformable, Oct 2011: “It is likely that the North Anna Operators are going to be shocked… when they open the reactor to attempt to refuel it, and find that they cannot retrieve the fuel”

3 years later >> Richmond Times-Dispatch, Sept 30, 2014: Dominion Virginia Power has foundtwo damaged nuclear fuel rods in its North Anna 2 power plant [NRC in 2011: “It is noteworthy that the power oscillations were more pronounced on Unit 2“]… 15 uranium fuel pellets came out of two rods… [CEO David Heacock said] rods rubbed against the support structure, cutting grooves in them and eventually causing their tops to crack off… “We have accounted for about eight of the pellets”… The failed fuel assembly had been used during three 18-month operating cycles at North Anna

U.S. NRC Event Notification Report, Sept 15, 2014: FAILED FUEL ASSEMBLY IDENTIFIED DURING CORE OFF-LOAD… North Anna Unit 2… Video inspection of the reactor vessel identified debris that has the potential to be fragments of fuel pellets resting on the core plate… this event is being reported [as an] event or condition that results in the condition of the nuclear plant, including its principle safety barriers, being seriously degraded.

France’s nuclear safety worries as fires break out close to 3 nuclear power plants

safety-symbol1flag-franceFrench police investigate fires near three nuclear sites http://uk.reuters.com/article/2015/05/12/uk-france-nuclear-fires-idUKKBN0NX1HD20150512 PARIS  French police are investigating fires that caused minor damage near three nuclear installations, state-owned utility EDF (EDF.PA) and atomic research agency CEA said on Tuesday.

Fires broke out on Monday morning at a weather station near EDF’s former Brennilis nuclear power station in Brittany and another near its Belleville nuclear plant on the Loire river, a spokeswoman said.

She said the fire had damaged equipment belonging to the IRSN nuclear research institute used to measure pollution and radioactivity at the weather stations, which are each about 1.5 kilometres away from the nuclear plants. “Police investigations are ongoing,” the EDF spokeswoman said.

Another fire was started on Monday evening at a weather station close to atomic research institute CEA’s Valduc site in Burgundy where nuclear weapons are manufactured and dismantled.

“There was the beginning of a fire, but it was quickly put out and there were no real consequences,” a CEA spokesman said, adding that a complaint had been filed with police.

The simultaneous incidents are reminiscent of drones that flew over French nuclear plants last year which raised safety concerns. [ID:nL5N0SR0DY] (Reporting by Michel Rose; editing by Jason Neely)

Alarm in New York following explosion at Indian Point Power Plant

New York Nuclear Scare After Explosion at Indian Point Power Plant New Yorkers contemplated the pros and cons of nuclear energy again Sunday after an explosion at Indian Point nuclear power plant in Westchester. By: Hana Levi Julian, Jewish Press  May 10th, 2015 “….The Indian Point nuclear power plant that provides 25 percent of the electric juice for the Big Apple and Westchester County went into “emergency response” late Saturday afternoon.

Billows of black smoke rose into the sky over the Indian Point nuclear power plant near Buchanan, New York.

A transformer failed, causing an explosion that ripped through the non-nuclear side of the plant.

The blaze was just 200 yards away from the building in which the reactor was located.

Firefighters who rushed to the scene were able to extinguish the flames, Entergy spokesperson Jerry Nappi told CNN, adding that one of the plant’s two reactor units automatically shut down.

No one was injured in the fire and there was “no threat to the public safety at any time. All Indian Point emergency systems worked as designed,” the facility said in a tweet.

But the fire had to be extinguished twice, because the flames re-ignited. Even so, the fire was out within half an hour.

Governor Andrew Cuomo received a briefing on site and told reporters, “These situations we take very seriously. This is a nuclear powered plant; it’s nothing to be trifled with.”http://www.jewishpress.com/news/breaking-news/new-york-nuclear-scare-after-explosion-at-indian-point-power-plant/2015/05/10/

Another shutdown at Oyster Creek Nuclear Plant

Oyster Creek Nuclear Plant Shuts Down Again, Patch.com  Exelon spokesperson says electrical disturbance responsible for latest scram. By PATRICIA A. MILLER (Patch Staff)May 8, 2015
The Oyster Creek Nuclear Plant in Lacey Township has shut down again, this time because of an electrical disturbance in the ”non-nuclear” part of the plant, spokesperson Suzanne D’Ambrosio said…….

he NRC ’s performance indicator for unplanned scrams for each 7,000 hours of operation changes from green to white if a nuclear plant has more than three unplanned shutdowns. Oyster Creek crossed the green/white threshold on July 11, 2014, when the plant had a fourth unplanned shutdown, the NRC has said.

Oyster Creek is the oldest nuclear plant in the United States. It went online on Dec. 23, 1969. http://patch.com/new-jersey/lacey/oyster-creek-nuclear-plant-shuts-down-again-0
