"일본원전 내진시설, 시대에 뒤떨어져 심각한 문제 발생할 수도"


국제원자력기구(IAEA)가 지난 2008년 12월에 일본 원전의 내진기준이 시대에 뒤떨어져 대규모 지진이 발생할 경우 "심각한 문제"가 발생할 수 있다고 경고한 사실이 <위키리크스> 문건을 통해 밝혀졌다.

영국 <텔레그라프>는 17일(현지시간) <위키리크스>가 입수한 미국 외교문건 내용에 기초해 이같이 보도했다.

<위키리크스> 문건에 따르면, 2008년 12월 일본 도쿄에서 열린 원자력안전보장에 관한 주요8개국(G8) 회의에서 IAEA 당국자는 "일본의 원전 내진 지침은 지난 35년간 3번밖에 갱신되지 않았다"며 "일본 원전의 내진기준이 시대에 뒤떨어져 대규모 지진이 발생할 경우 심각한 문제가 발생할 수 있다"고 경고했다.

하지만 일본정부는 이 경고를 묵살했고 결국 후쿠시마 원전 참사가 발생하게 됐다는 것.

IAEA의 아마노 유키야 사무총장은 <위키리크스> 문건의 진위를 묻는 질문에 "노코멘트"라고 답해, 사실상 문건의 진실을 시인했다.

<텔레그라프>는 "후쿠시마 원전이 규모 7의 지진에 견딜수 있게 설계돼 규모 9.0의 3.11 대지진에 피해를 입을 수 밖에 없었다"고 덧붙였다.

SUBJECT: LOCAL COURT ORDERS SHUTDOWN OF NUCLEAR REACTOR

REF: A. 05 TOKYO 4067

B. NAGOYA 003

TOKYO 00001592 001.2 OF 003

-- Summary --

1. (SBU) On March 24, the Kanazawa District Court ordered the Hokuriku Electric Power Company (Rikuden) to shut down operations at Unit Two of its Shika Nuclear Power Plant due to safety concerns over its ability to withstand powerful earthquakes. The court ruled that there was a real possibility that the plaintiffs might be exposed to radiation if there was an accident at the plant. The operator called the ruling "unreasonable" and said it would immediately file an appeal to a higher court. The Nuclear and Industrial Safety Agency (NISA) believes the reactor is safe and that all safety analyses were appropriately conducted. As a result, the GOJ sees no reason why Rikuden should shut down the unit. Though not legally obligated to cease operations in this case since this is a civil suit, Rikuden will face an uphill battle to regain the support of local citizens for operating a nuclear facility in their backyards. End summary.

-- The Case --

2. (U) On March 24, the Kanazawa District Court ordered the Hokuriku Electric Power Company (Rikuden) to shut down operations at Unit Two of its Shika Nuclear Power Plant (NPP) due to safety concerns over its ability to withstand powerful earthquakes. A group of 135 plaintiffs from across the country filed the suit against Rikuden in May 2005, after the operator began trial operations, arguing that its anti-seismic design was insufficient and the advanced boiling water reactor (ABWR) design was inherently dangerous. The suit followed up on an earlier unsuccessful attempt to halt the construction of the new reactor. The plaintiffs pointed to a study commissioned by the GOJ"s Earthquake Research Committee that concluded there was a two percent chance that an earthquake with a magnitude of 7.6 or higher could occur along the 44-kilometer long Ochigata fault, which runs near the NPP. The unit was built to withstand a magnitude 6.5 earthquake. The plaintiffs claimed that Unit Two was built to seismic specifications established more than two decades earlier and therefore posed a direct threat to their safety.

3. (U) According to press coverage, the presiding judge said that Rikuden had not taken into consideration an earthquake that may occur along the Ochigata Fault when building the new reactor. In addition, the judge stated that there was a real possibility that the plaintiffs might be exposed to radiation if there was an accident at the plant due to a large earthquake. The court argued that Rikuden"s estimates of potential earthquakes in the area were too conservative. The court, however, rejected the group"s claim that the ABWR design was unsafe, citing lack of evidence.

-- Rikuden"s Response --

4. (U) Rikuden President Isao Nagahara issued a press release later on the same day in which he called the Kanazawa District Court"s decision not to recognize the safety of Unit Two "truly regrettable". He also said that it was an "unreasonable ruling" and that Rikuden would immediately file an appeal to a higher court. The President also stated that the GOJ is currently examining its anti-seismicity design specifications, and if there were to be a change to those specifications, Rikuden would ensure that the safety of its reactors would be up to par

with any new requirements. Unit Two began operations on March 15 after successfully passing the final government required inspections and, according to the operator, is currently operating safely. Nagahara concluded his statement by promising that Rikuden was sufficiently ensuring the operational safety of the reactor, and as a result, would continue operating it even in light of the court decision.

TOKYO 00001592 002.2 OF 003

5. (SBU) An official at the Nuclear and Industrial Safety Agency (NISA) explained to ESToff that the case in question was a civil lawsuit and that the ruling did not require immediate implementation of the order to shut down the reactor. Had the ruling directly questioned the validity of the national regulations themselves through an administrative lawsuit -- as in the case of the earlier Monju litigation -- then Rikuden would have been obliged to shut the reactor down. Given the legal differences,

however, the official said that Rikuden could continue operating as is.

6. (U) In its 2005 annual report, Rikuden wrote that it places top priority on the safe and stable operation of the Shika NPP. The operator said it was determined to continuously improve its quality management system through auditing and by taking into consideration the advice of an outside experts" panel on nuclear power safety and quality. Because the operator is convinced its plant is safe, Rikuden has announced it will continue operating Unit Two for the time being.

-- Government Regulators Surprised at Ruling, but not Concerned over Safety --

7. (U) Most of the national dailies ran stories covering the court decision, and speculated that it would send shivers throughout the industry. The Yomiuri quoted NISA"s Director-General Kenkichi Hirose as saying "I"ve never thought that a court would order the cessation of the plant"s operation." Other dailies wrote that as a result of the decision, Japan"s Nuclear Safety Commission was scrambling to formulate new anti-seismic design regulations by this summer.

8. (SBU) ESToff called NISA"s International Affairs Office Director Michio Hashimoto to obtain further information on the regulator"s position on the court ruling. Hashimoto said that NISA believes the reactor is safe and that all safety analyses were appropriately conducted. As a result, NISA saw no reason why Rikuden should shutdown Unit Two.

9. (SBU) EST FSN also called Takuya Itoh, Staff Manager of the Federation of Electric Power Companies" Public Relations Department for the industry group"s position on the court ruling. Itoh said that the Federation was taking the decision seriously. The group will continue its efforts to ensure that all of Japan"s nuclear facilities operate safely and will work to obtain public acceptance of the facilities. As an aside, he told EST FSN that he personally does not feel that others in the Federation were overly concerned about the result of the lawsuit.
