OKUMA, Japan, March 16 (UPI) - large radiation contamination threatens Japan's Quake crippled Fukushima nuclear plant as a Wednesday morning reactor fire made matter worse, officials said.

Tokyo Electric Power Co., the operator said that the fire, which flamed appeared until 30 minutes after she flared died, the reactor No. 4 at the plant, Kyodo News reported. The plant has six reactors.

The utility of "Re criticality," concerned to stop given helicopter boric acid as redecorate spraying nuclear fuel rods again reach boiling levels, which in turn to a chain reaction, could the way what is called, the report said.

The Government wants the utility, used to more Pacific sea water in a pool, to cool spent nuclear fuel rods inject "as soon as possible, avert a major nuclear disaster" the report said. Without the required water levels, the exposed rods of radioactive leaks could start.

High doses of radiation as a result of three previous explosions in various reactors and fires, as the 9-magnitude quake and tsunami Friday were forced to hit, the utility to evacuate most of the 800 workers at the site.

The utility "The possibility of re criticality is not NULL,", said Wednesday. "

Kyodo quoted Tokyo Electric an estimated 70 per cent were the fuel rods at the plant No. 1 reactor and 33 percent for the No. 2 reactor, while the cores on both damaged these reactors will have melted perhaps partially facilities without their cooling.

Before the quake for routine inspections were Wednesday of flames on the fourth floor of the reactor No. 4, seen, stopped as reactors 5 and 6 were had. These flames were probably at the same time on the ground where a suspected hydrogen Tuesday morning a fire caused explosion, which then put out was.

James Walsh, researchers at the Massachusetts Institute of technology, told CNN that the crucial question was now whether the fuel rods were melting and whether they contain can be.

The New York Times reported that the utility has said that to go in it becomes dangerous for workers close to some of the reactors.

Officials say the times quoted US nuclear regulatory Commission, which she was told by the Japanese authorities, the fire would be the result of burning oil of machinery in the vicinity of the pool.

The report said, there were also concerns about memory pools in no. 5 and 6 reactors.

The times said 50 workers currently on the site in a protected control room, injections by temporary fire pumps in reactors 1, 2 and 3, to make sure that the fuel rods boil over work while monitoring sea water.

Some U.S. military ordered ships to support affected regions have in that disaster was temporarily diverted due to the increased radiation leaks. However, the United States Navy has still decided their helicopter relief missions despite some of the crew, low-level radiation is made available.

Japanese Prime Minister Naoto Kan told the risk of rising radiation of the nation and Chief has asked Cabinet Secretary Yukio Edano home stay within a 17-mile radius of the work of Fukushima.

Higher levels of radiation were detected in the area of Tokyo.

Adams numbering in the dozens continue the earthquake affected region since Friday torment.

Expert concerns, the Los Angeles Times about the Friday Quake set off a shock for Tokyo closer as the aftershocks South of Sendai, the capital of the worse hit Miyagi-Prefecture 230 miles north promoted.

A 6.2-magnitude aftershock was recorded Tuesday night Southwest near the city of Shizuoka, 72 km of Tokyo, report. Metropolitan area is the Tokyo more than 32 million people.

CNN reported that the direction of the winds, which could be an important factor was towards the sea as of Wednesday morning.

In other developments, had on Wednesday, stock prices in early trading on the Tokyo Stock Exchange is restored hammered in the last two days. The benchmark stock market index was Nikkei 225 Wednesday after plunging more than 16 percent on Monday and Tuesday combined more than 4 percent in intraday trading,.

The Japanese Central Bank has to confidence in the economy to restore pumps unprecedented amounts, ensure sufficient liquidity and that banks make loans to each other and others.
