#TEPCO Downgrades Thermometers After 80°C Spike, But Data Suggests a Systemic Issue

"TEPCO recently reported that a thermometer in #FukushimaDaiichi’s Reactor 1 recorded an unexpected 80°C temperature increase following nitrogen injection into the primary containment vessel (#PCV). Initially, this raised concerns about a possible heat source inside the containment vessel .

"However, after an internal review, TEPCO concluded that the reading did not reflect an actual temperature increase, attributing it to instrument malfunction. As a result, they downgraded multiple thermometers to “reference use” and removed them from official monitoring .
Contradictions in TEPCO’s Explanation

"TEPCO’s official report claims that the 80°C spike was a sensor anomaly, yet the data contradicts this conclusion..."

Declining Interest and Zero Successful Proposals in Tritium Removal Technology for ALPS Water
Steep Decline in Tritium Removal Proposals

TEPCO’s latest report on tritium removal technologies for ALPS-treated water highlights a drastic drop in submitted proposals over time. Since the call for technologies began in May 2021, the number of proposals has plummeted:

First round (2021): 65 proposals
Eighth round (2024): 7 proposals
Ninth round (2025): 2 proposals​

This sharp decline suggests a lack of viable technical solutions or diminishing interest from researchers and industry.
Zero Cases Passed Initial Evaluation in Recent Rounds

In early recruitment phases (2021-2022), 15 proposals passed the initial evaluation and moved on to secondary feasibility studies.
However, in the fourth, fifth, seventh, eighth, and ninth rounds, not a single proposal passed the initial evaluation.
In the most recent ninth round (July – December 2024), only two proposals were submitted, and both failed to meet TEPCO’s evaluation criteria​.

Why Are No Proposals Passing?

TEPCO’s report states that the submitted proposals failed due to:

Lack of technical justification for tritium separation methods
Inability to meet TEPCO’s separation criteria
Insufficient data to verify feasibility​.

The complete lack of successful proposals raises questions about whether a viable tritium removal solution exists at all. For now, it appears that controlled dilution and ocean discharge remain the only “practical approach”—despite ongoing concerns and criticism.

トリチウム除去技術の公募が低迷、成功例ゼロに
トリチウム除去技術の提案数が激減

東京電力の最新報告によると、ALPS処理水のトリチウム除去技術の公募に対する提案数が大幅に減少していることが明らかになりました。
2021年5月に公募が開始されて以来、提案数は以下のように推移しています：

第1回募集（2021年）： 65件
第8回募集（2024年）： 7件
第9回募集（2025年）： 2件​

この急激な減少は、技術的な課題の難しさや、研究機関や企業の関心の低下を示している可能性があります。
直近の募集では初期評価通過例がゼロ

2021年～2022年の初期段階では、15件の提案が一次評価を通過し、二次評価（フィージビリティスタディ）に進みました。
しかし、第4回・第5回・第7回・第8回・第9回募集では、一件も一次評価を通過せず、成功例が完全に消滅しました。
最新の第9回募集（2024年7月～12月）では、わずか2件の提案しか提出されず、両方とも基準を満たさず不合格となりました​。

Former TEPCO Chairman #Katsumata’s Passing Sparks Reflections on Accountability in the #FukushimaDisaster

Katsumata’s Legacy as “The Emperor” of TEPCO

"Tsunehisa Katsumata, former chairman of Tokyo Electric Power Company (TEPCO), passed away at age 84 on October 21. Known as the 'Emperor' within TEPCO due to his powerful influence, Katsumata led the company through significant periods, including the 2011 Fukushima Daiichi nuclear disaster. However, despite his long-standing authority, he left without resolving key decommissioning issues at Fukushima​.

Awareness of Tsunami Risk Without Action

"In February 2009, a critical internal meeting—later known as the 'Gozen Kaigi' (御前会議) —highlighted the risk of a tsunami exceeding the plant’s protective barriers. Despite this, Katsumata refrained from directing immediate countermeasures, even as the potential threat to Fukushima loomed.

Legal Challenges and Unpaid Compensation

"Following the Fukushima disaster, Katsumata and other former executives faced multiple lawsuits, including a landmark shareholder derivative suit that ordered him and three other former executives to pay over 13 trillion yen (around 100 billion USD). Despite this ruling, compensation had yet to be paid by the time of his passing.

"In July 2022, a civil court held TEPCO executives accountable for negligence regarding tsunami countermeasures, noting that if measures had been implemented, the disaster’s impact could have been significantly reduced. This marked the first time former management was deemed financially responsible on such a large scale.

Mixed Reactions to His Death

"The news of Katsumata’s death has triggered complex responses, especially among Fukushima survivors. Many feel unresolved anger, recalling his persistent denial of responsibility during trial testimonies, where he often claimed ignorance on technical matters. Katsumata’s departure symbolizes the long-standing challenges of achieving justice and closure for the victims of Fukushima."

Camera revealed base concrete of reactor 1 is substantially lost all around

August 2023, via #FukushimaDiary

"On the 4th of April, 2023, #Tepco released the reactor 1 investigation report that describes the damage scale inside the base of reactor 1. This investigation was implemented one week before the data release. This research was aimed to complement the previous research carried out last year.

"The connected data of two investigations from last year and this year revealed the significant parts of the concrete base of reactor 1 have already disappeared. The base is a ring shaped structure made of concrete with 1.2m thickness. From the bottom to 1m height, the iron reinforcing bars were exposed to the outside. This means, the concrete base was likely to be evaporated at over 2,800 celsius degrees up to 0.6m thickness. However, it is not clear why the iron bars were not affected by the heat.

"On the bottom of the inside of the base, debris was observed to be accumulating with up to 1m thickness, which is assumed to be the mixture of molten fuel and internal structures of the reactor container vessel. Some parts of the control rod facility were also seen lying on the layered debris, however the rest of the control rod facility is still unstably hanging in the vessel. Even though most parts of the base still can have a half thickness, based on Tepco’s estimate, the concrete is “broken though” at a 60 degree angle around the open door of the base with only iron bars supporting the whole base. In case another major quake hits Fukushima, there’s a risk that the entire base collapses. Tepco admitted this possibility, yet stated it wouldn’t sink more than 30cm due to the exterior structure. However, if the large part of the control rod facility hanging in the vessel falls onto the molten debris, it may crack the debris into small pieces and trigger a #recriticality accident according to Tepco. The Nuclear Regulation Authority of Japan demanded Tepco to draft countermeasures but Tepco states the probability of such an accident is significantly low."

#Tepco’s been emphasizing the safety of contaminated water by measuring with incompatible dosimeters

by Mochizuki, #FukushimaDiary, November 3, 2022

"It was found out Tepco has repeatedly been emphasizing the safety of contaminated water by using dosimeters that cannot detect the radioactive tritium and that do not react to cesium unless the concentration level is extremely high.

"Nature of the water to be discharged to the Pacific is the filtered highly-concentrated contaminated water generated by cooling the nuclear fuel that has melted down into the reactor at least twice, and is announced to contain only tritium. Tritium cannot be removed even with decontamination equipment.

"However During the demonstration to the press, a dosimeter that detects only extremely high levels of gamma rays was applied to a bottle containing the contaminated water, which showed no detection. Since July 2020. TEPCO has been repeating this performance to about 1,300 groups and 15,000 people."

180 times much as #radioactive #cesium detected in fish from #Fukushima #nuclear plant port

via #FukushimaDiary

"On the 5th of June, 2023, #Tepco announced they detected 18,000 Bq/Kg of radioactive cesium from Black rockfish collected in the port of the crippled nuclear plant of Fukushima.

"This is 180 times much as the current food safety standard (100 Bq/Kg).

"Moreover, the detected 18,000 Bq/Kg of radioactive cesium consists of Cs-134 and Cs-137.

"The half-life of Cs-134 is up to 2 years, nevertheless this black rockfish contained 380 Bq/Kg of Cs-134. Tepco has not publicly made an announcement regarding the detection of Cs-134."
