Worker hurt as uranium container explodes in nuclear lab



OKAYAMA, Japan, Jan. 21 (Kyodo) - A worker was injured in the face 

and eyes Tuesday when a container holding a uranium solution exploded 

at a laboratory of a prototype uranium-enrichment plant in Okayama 

Prefecture of the state-run Japan Nuclear Cycle Development 

Institute, officials said.



The institute's Ningyo-Toge Environmental Engineering Center said the 

incident poses no environmental threat to surrounding areas, and the 

worker's skin was not contaminated with uranium and he was not 

exposed to radiation internally.



The 22-year-old man, an employee of a subcontractor in Ibaraki 

Prefecture, was bleeding from a cut above his eye caused by glass 

shards, and one of his corneas was injured by the solution. He was 

taken to a hospital in Kurayoshi, Tottori Prefecture.



The accident happened around 3 p.m. at a chemical laboratory at the 

center when the worker was removing uranium from liquid nitric acid 

in the 30-centimeter-long glass container, which suddenly burst.



The procedure was a preparation for operations to measure impurities 

in depleted uranium, the center said.



''We are very sorry for the accident,'' said Chosuke Kuronuma, head 

of the Ningyo-Toge Environmental Engineering Center. ''We will work 

to determine the cause and to prevent a recurrence.''



Two other workers were inside the lab when the explosion occurred but 

they were not injured, the officials said.



The lab and nuclear safety inspectors from the Ministry of Education, 

Culture, Sports, Science and Technology said they are investigating 

the cause.



The Ningyo-Toge Environmental Engineering Center is located in 

Kamisaibara, a village bordering Tottori Prefecture and close to 

Ningyo Pass, which contains uranium ore. It conducted a large 

antidisaster drill last November with the Okayama and Tottori 

prefectural governments.



The facility specializes in developing techniques used to refine 

uranium ores and enrich uranium.

Japanese Gov't allows 2 nuclear reactors to run with cracked shrouds



TOKYO, Jan. 21 (Kyodo) - The government decided Tuesday to allow 

Tokyo Electric Power Co. and Chubu Electric Power Co. to run a 

nuclear reactor each with cracks in core shrouds left unrepaired, 

saying the damage will have no effect on the plants' safety over the 

next five years.



At issue are the No. 3 reactor at Tokyo Electric's Kashiwazaki-Kariwa 

nuclear plant in Niigata Prefecture and the No. 4 reactor at Chubu 

Electric's Hamaoka plant in Shizuoka Prefecture, whose operations 

have been suspended for regular checks.



It is the first time the Industrial and Nuclear Safety Agency under 

the Ministry of Economy, Trade and Industry has permitted a specific 

reactor to operate without cracks repaired, in line with a policy 

adopted last December.



The agency's green light was given on condition that the cracks will 

come under the government's regular facility inspections, agency 

officials said.



But the agency urged Tokyo Electric to fix some of the cracks in the 

Kashiwazaki-Kariwa No. 3 reactor shroud that are believed to be 

expanding, before danger becomes imminent, the officials said.



A subgroup under the Advisory Committee for Natural Resources and 

Energy, which advises the economy, trade and industry minister on 

technical matters, endorsed the government decisions in a meeting the 

same day.



The decisions were made at a time when the Tokyo-based and Nagoya-

based power utilities were considering whether to repair the shrouds 

in question before resuming operation of the two reactors.



The resumption of operations of the reactors concerned now hinges on 

whether the power companies manage to win support from local 

governments and residents.



An official of the Niigata prefectural government in charge of 

nuclear safety, who attended the meeting, urged the government to 

thoroughly check these facilities, strictly assess their safety and 

assume the responsibility of explaining results to local residents.



The agency unveiled a plan Dec. 25 to allow nuclear power operators 

to resume operating damaged reactors if their safety can be ensured 

for a period of five years and inspections are made regularly.



Under the policy, which came in response to Tokyo Electric's reactor 

damage cover-up scandal revealed last August, reactors with cracks in 

shrouds could be left running if the unscathed areas are strong 

enough to cope with an earthquake.

Japanese Gov't eyes power to close nuke plants before emergency



TOKYO, Jan. 19 (Kyodo) - The Japanese government is considering 

legislation giving it the authority to shut down nuclear power plants 

and other high-risk facilities as part of safety measures prior to 

emergencies to protect citizens, government sources said Sunday.



Current laws stipulate that the government can order nuclear power 

plants to take necessary measures to prevent disasters in times of 

earthquakes and catastrophes.



According to an outline of the legislation drawn up by the government 

and the ruling coalition, the government may order operations of 

nuclear plants to be terminate even before an emergency should it 

expect a military attack, while evacuating residents through local 

authorities.



In addition to nuclear power plants and research facilities for 

infectious diseases, other facilities such as those involving 

radioactive substances and chemical factories are also targeted, the 

sources said.



The government will begin explaining details of the legislation to 

local authorities, private operators of essential utilities such as 

electricity and gas, and other concerned parties when the Diet 

convenes for its ordinary session Monday, the sources said.



The legislation to protect citizens is to be developed within two 

years after the enactment of a set of war contingency bills, which 

the ruling coalition hopes the Diet will pass in its regular session.
