The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Cs-134/137 density of plant port water keeps increasing since last week


Cs-134/137 density reached the highest level at 2 of those 4 points mentioned above, according to Tepco. The sampling date was 9/7/2015.

These 2 points are in front of water intakes of Reactor 1 and Reactor 2. Both of them are outside of underground wall to prove high level of contamination is still leaking to the sea.

Also, Cs-134/137 density in the south of these 2 points reached the highest level. This is also outside of the underground wall, but the density went up approx. 170 % of the previous highest reading. The newly highest Cs-134/137 density was 152,000 Bq/m3.

CSRP 2015 – The Fifth Citizen-Scientist International Symposium on Radiation Protection


Beginning in March 2011, the Tokyo Electric Fukushima Daiichi nuclear power plant catastrophe continues even now with no end in sight. We have sought out ways to reduce even a little, or possibly prevent, health effects due to radiation exposure. Whether radiation exposure leads to health effects, or what the potential health effects might be, has generated much interest in our society. However, up to now, no discussion has been openly carried out amongst scientists with various viewpoints. The nuclear power plant accident and the dispersed radioactivity exert influences over extensive social areas, affecting individuals as well as the society. What is called for now is societal decision-making regarding such influences for the purpose of radiation protecton, through discussions between the victims, the political decision-makers, the researchers, and the non-governmental organizations.
Currently, the exposed and the highly exposed human populations are either ignored by the government or they become inadvertent subjects of observation by scientists, while silently and helplessly observing incidences of illness creeping up within themselves. Epidemiological studies, deemed essential in putting public health into practice, are not cold science by any means. The purpose of epidemiological studies should include, in addition to the elucidation of frequency and causes of illnesses, the creation of frameworks to minimize health effects by reducing or preventing them. Furthermore, the true goal of epidemiological studies is for them to be utilized in reducing or preventing societal effects which could worsen the catastrophe.

What approaches are needed for science to become a survival tool for humans in the challenge of radiation protection? We shall think about this issue together at the Fifth Citizen-Scientist International Symposium on Radiation Protection,

On Day 1 of the symposium, we will approach this issue from the diverse intellectual interactions between science and art.

On Day 2, we will explore epidemiology as a science in addition to a general overview of radiation protection measures based on the latest biological findings.

Lastly, on Day 3, we will verify from societal aspects what language, law and ethics are necessary in order to put such measures into practice.

Tepco’s index-topping gains fueled by electricity shake-up

Japan’s reform of its energy market is proving a boon to investors in the company at the center of the Fukushima No. 1 nuclear plant disaster.
Tokyo Electric Power Co.’s shares have surged 59 percent in the six months through Tuesday’s close, making it the best performer on the Nikkei 225 Stock Average and the 174-member Bloomberg World Utilities Index.
Tepco, owner of the wrecked plant, is seen as an early beneficiary of government-backed power reform. By April, residential power customers will be able to choose their provider for the first time. And by 2020, utilities will be required to separate their transmission, distribution and retail businesses.
“Looking towards the electricity market reform to be completed by 2020, a company the size of Tepco is an attractive investment,” Mana Nakazora, an analyst at BNP Paribas Securities (Japan) Ltd., said by email.
While the company’s stock price has surged this year, it is still less than half of where it was before the Fukushima disaster. The shares fell 3.1 percent to ¥751 at the close of Tokyo trading on Tuesday. They closed at ¥2,153 the day before Fukushima, but have increased 55 percent since Tepco announced on May 1 that it will transition to a holding company beginning in April.
Tepco was rated new overweight on Tuesday with a target price of ¥1,000 a share by Yuji Nishiyama, an analyst at JPMorgan Securities Japan Co.
Spokesman Tatsuhiro Yamagishi declined to comment on the performance of the company’s stock.
For Tepco, a more open energy market in Japan offers the opportunity for growth at a company whose survival was in question just a few years ago. The Fukushima disaster put it on the verge of default, with the head of Japan’s biggest stock market telling the company to file for bankruptcy protection. Tepco was saved by a ¥1 trillion infusion from the government in 2012, the nation’s largest bailout since the 1990s.
The power company received ¥5.61 trillion from the state-backed Nuclear Damage Compensation and Decommissioning Facilitation Corp. to deal with payouts to victims of the Fukushima meltdown, Tepco reported last month.
Under the April reorganization, Tepco’s nuclear operations will be placed into a holding company, while debt investors will be repaid from the funds of a spun-off power grid company.
Tepco’s probability of debt nonpayment has dropped to 0.309 percent from about 1.121 percent on Oct. 16, according to the Bloomberg default-risk model, which considers factors such as share prices and debt. The probability of debt nonpayment was as high as 6.156 percent in 2012.
“The company’s default risk has disappeared,” said BNP Paribas’s Nakazora.
The government’s power reform began this year with the creation of an organization to manage the nation’s supply and demand balance. Next year’s full retail liberalization, the second stage of the reform, will allow utilities to more freely expand outside their traditional regions. The government aims to remove rate regulations by 2020.
A drop in fuel costs saw Tepco increase operating profit threefold in the quarter ended June 30. The price of liquefied natural gas imported into Japan fell to a six-year low in June, while crude oil prices are near a record low.
“Investors expected first-quarter profits to have a big increase due to the drop in oil then liquefied natural gas,” Syusaku Nishikawa, a Tokyo-based analyst at Daiwa Securities Co., said by email.
Yet challenges remain. Liabilities related to the Fukushima disaster and Tepco’s responsibilities will continue to pressure the company’s credit quality in the long term, according to Mariko Semetko, a vice president at Moody’s Japan K.K., which rates the company’s outlook as negative.
Tepco, which operates the world’s biggest nuclear plant by capacity at its Kashiwazaki-Kariwa facility in Niigata Prefecture, has yet to restart any of its nuclear reactors. Resuming operations at the facility would boost profit by as much as ¥32 billion a month, the company has said.
“The recent improvements in profitability are definitely a plus,” Semetko said by phone. “But the company hasn’t yet started its Kashiwazaki-Kariwa plant and there are a lot of uncertainties around costs related to Fukushima. With all of that in mind, we haven’t been able to stabilize the outlook yet.”

Third ceiling panel removed from Fukushima reactor

Workers at the Fukushima Daiichi nuclear plant have removed half of the ceiling panels covering a damaged reactor building. The work is part of efforts to decommission the facility.

The No.1 reactor building was heavily damaged by a hydrogen explosion during the 2011 meltdown. Tokyo Electric Power Company installed a cover around it to prevent the spread of radioactive material.

The utility is now removing the cover so it can clean up debris inside the facility. Two of the 6 ceiling panels that make up the cover were removed between late July and early August.

The utility then halted the work to monitor radiation levels and check the conditions of the debris. Since no abnormalities were found, workers removed a 3rd panel on Tuesday using a remote-controlled crane.

TEPCO says there’s been no change in radiation levels around the reactor buildings. It says measurements taken before the work on Tuesday showed that wind blowing inside the cover was weaker than expected.

The utility plans to finish dismantling the cover by around late next year.

Groundwater to be released into the sea on Monday

The operator of the Fukushima Daiichi nuclear plant plans to start releasing groundwater from around reactor buildings into the sea next Monday.

The government and the operator, Tokyo Electric Power Company, are to formally decide on the discharge date on Wednesday. The water has already been decontaminated.

Officials hope the move will help to curb the accumulation of radioactive wastewater in the reactor buildings. The contaminated water is increasing at a rate of 300 tons a day as the groundwater flows in.

The officials plan to first release some 4,000 tons of water pumped up from the wells around the buildings on a trial basis since August last year.

They say they will continue to pump up water and release it after removing radioactive materials.

Later this week, the utility also plans to resume the construction of steel walls along the coast to stop the groundwater seeping directly into the sea.

The construction work has been suspended until the release of the groundwater becomes possible.
