It is the most significant long-lived fission product of uranium fission, with a half-life over 2000 times as long as the next longest-lived fission product. Technetium-99 has a fission product yield of 6.0507% for thermal neutron fission of uranium-235.
County Response to Technetium 99 Incident at LANL 8/29/2012 Los Alamos County officials participated in a briefing this morning with DOE officials regarding last week’s incident involving the inadvertent spread of Technetium 99 by lab employees and contractors working at the Lujan Neutron Scattering Center at LANSCE. After several days of interviews, measuring, surveying and assessment, the DOE’s Radiological Assistance Program (RAP) has been able to successfully identify all individuals and report on their whereabouts since the incident occurred. About a dozen people had been reportedly involved in the incident, many of whom live in Los Alamos or White Rock. The RAP team’s assessment showed that exposure to the community was limited, has been sufficiently characterized and remediated, and never posed any public health risk to residents, due to the small amounts of Technetium 99 tracked off site and the low-level type of beta radiation emitted by Technetium 99. “We appreciate the thoroughness and swift response of the RAP team in addressing the situation, and are appreciative of the DOE’s efforts to include us in today’s briefing about their findings,” said Acting Council Chair Geoff Rodgers, “We continue to stand ready to assist the DOE and Laboratory in any way we can. While any release of potentially hazardous or harmful materials at LANL is unacceptable, we were immediately alerted to the situation last week and have been kept informed and involved by their emergency management response teams as they gathered information. We urge NNSA and LANL to continue their due diligence into the investigation of how and why this incident occurred, and to report back to the County on their findings, so that we can rest assured that every precaution will be taken to see that last week’s incident won’t be repeated again in the future.” The Lab’s official report on the incident can be found on their website at www.lanl.gov.
The head of the Japanese utility that owns the tsunami-hit Fukushima nuclear power plant says last year's meltdowns sapped away money it might have used to switch to alternative energy, making it all the more important for the company to stick with nuclear.
Naomi Hirose, president of Tokyo Electric Power Co., said Thursday it is "quite troubling" that the government, responding to public opinion, is moving toward eliminating nuclear power, but he said TEPCO would follow whatever energy policy Japan adopts.
The March 11, 2011, earthquake and tsunami wiped out the Fukushima Dai-ichi plant and caused extensive radioactive meltdowns that took months to control and will take decades to clean up. It was the world's worst nuclear accident since Chernobyl.
TOKYO--The new head of Japan's biggest electric company aired concerns about the possibility that Japan could phase out nuclear power, saying that such a move would necessitate a "complete" revamping of its investment and fuel-procurement plans, and could be detrimental to the country's energy security as well.
"Based on Japan's past experience (of oil shortages in the 1970s), it'd be wiser to have diversity" in Japan's energy mix, both in the kinds of fuels used and the places they are bought from, Naomi Hirose, president of Tokyo Electric Power Co. (9501), told The Wall Street Journal on Wednesday. After the oil shocks, "we had to sharply hike rates twice, and Japanese society fell into chaos," he said.
Mr. Hirose's comments come the week before the administration of Prime Minister Yoshihiko Noda is expected to announce a long-awaited decision on Japan's future energy mix, following last year's devastating accident at the Fukushima Daiichi nuclear power plant. Japanese utilities and many big business have come out strongly in support of maintaining the country's nuclear fleet, which supplied around 30% of the country's electricity before the accident.
TOKYO — Japan would be foolish to abandon nuclear power, the operator of the ravaged Fukushima Daiichi Nuclear Power Station warned Wednesday, saying the company had not ruled out reopening two of the plant’s less-damaged reactors as well as four others at a nearby sister site.
The country is expected to outline a new energy policy, prompted by the disaster at Fukushima, and one option the government has explored would phase out all nuclear power by 2030.
Public anxiety over nuclear safety has helped keep all but two of Japan’s 50 remaining reactors offline, and the country’s nascent anti-nuclear movement has demanded an even more immediate shutdown.
TOKYO (Nikkei)--Prices of peaches and pears from Fukushima Prefecture are gradually returning to normal levels, following a plunge triggered by radiation fears in the wake of the accident at Tokyo Electric Power Co.'s (9501) Fukushima Daiichi nuclear power plant in March 2011.
Recent tests showed negligible radiation levels in fruit grown in the prefecture, thanks to efforts to eliminate contaminated trees.
Peach prices have risen to 80% of the level seen before the nuclear accident, while prices of pears have already returned to pre-disaster levels.
However, prices of fruit used as gifts are recovering at a slower pace, because consumers appear to be reluctant to give gifts that could be associated with radioactive contamination.
TOKYO (Nikkei)--Tokyo Electric Power Co. (9501) decided Friday to set aside 230.34 million yen for compensation to 22 executives for the one-year period that started in June, or roughly one-quarter what it paid before the Fukushima Daiichi nuclear crisis.
President Naomi Hirose and 14 other executive officers will receive a total 195 million yen, or 13 million yen each on average.
Due to the March 2011 disaster, the utility known as Tepco canceled all compensation from May of that year for the chairman, the president and executive vice presidents.
In June, Tepco overhauled its top brass and adopted committee-style governance. The compensation committee, comprised of independent directors, concluded that executive compensation should resume to ensure the company can secure management talent.
Six independent directors, including Chairman Kazuhiko Shimokobe, have been allotted 20.34 million yen. Shimokobe, however, has declined the compensation, according to Tepco.
Prior to the crisis, Tepco's compensation for 33 executives, including auditors, reached 864 million yen. Its 22 in-house directors pocketed 700 million yen combined, or an average of 31.81 million yen apiece.

KYOTO — The risk of a fire starting in reactor 4's spent-fuel pool at the Fukushima No. 1 plant continues to alarm scientists and government officials around the world, prompting a leading U.S. nuclear expert to urge Japan to tap global expertise to avert a catastrophe.
Arnie Gundersen, a nuclear engineer and former executive in the nuclear power industry who is now one of its foremost critics in the United States, has been monitoring the No. 1 plant since the March 2011 triple meltdowns through his Vermont-based Fairewinds Energy Education nonprofit organization.
During a trip to Japan in late August and early September, Gundersen met with Diet members, lawyers and citizens' groups to discuss conditions at the wrecked power station and told an audience in Kyoto on Monday that fears over the spent-fuel pool in reactor 4 remain high.
The AEC and Taipower often criticize Tokyo Electric Power Co for not wanting to risk its nuclear reactors during the initial stages of the Fukushima nuclear disaster and therefore hesitated before applying such “drastic measures,” and this is why things spiraled out of control.
The AEC and Taipower are wrong. Taiwan’s three currently operational nuclear power plants have been on the go for 30 years, and they are getting dangerously old.
Fractures have been discovered in anchorage bolts in both units of the Guosheng Nuclear Power Plant in New Taipei City’s Wanli District (萬里) and it is possible that other, more fragile components — such as pipes, pumps, controls and circuits — would warp during an earthquake.

A cross-party group of 91 lawmakers said Thursday 28 of Japan's 50 commercial nuclear reactors must immediately be decommissioned and the rest are dangerous.
The group, which in late June proposed immediately decommissioning 24 reactors, has added four more to the list -- two at the Mihama power plant in Fukui Prefecture operated by Kansai Electric Power Co. and two at the Shika plant in Ishikawa Prefecture operated by Hokuriku Electric Power Co.
The group said faults are believed to lie beneath those four reactors.
The other 24 reactors included three at the Hamaoka power plant in Shizuoka Prefecture operated by Chubu Electric Power Co., and two at the Tsuruga power station in Fukui Prefecture operated by Japan Atomic Power Co.
One at the Higashidori plant in Aomori Prefecture and two at the Onagawa plant in Miyagi prefecture, all run by Tohoku Electric Power Co., and six reactors at Tokyo Electric Power Co.'s Fukushima Daiichi and Daini plants in Fukushima Prefecture were also on the list.
The government and Tokyo Electric have already decided to decommission four of the six reactors at the Fukushima Daiichi plant seriously damaged as a result of the March 11, 2011 earthquake-tsunami disaster.
In creating the list, the lawmakers group said it looked into such elements as the type, age and earthquake resistance of the reactors.
In the June list, the No. 1 and No. 2 reactors at Kansai Electric's Oi power plant in Fukui Prefecture ranked top in terms of risks.
Kansai Electric restarted the No. 3 and No. 4 reactors at the Oi plant in July, making them the first among the country's commercial reactors to resume operating after being shut down for mandatory safety checks since the March 2011 disaster at the Fukushima Daiichi nuclear plant.
The 91 lawmakers included 27 from the governing Democratic Party of Japan, but only three from the main opposition Liberal Democratic Party and one from the Buddhist-backed New Komeito party, the LDP's junior partner.

The Japan Atomic Energy Commission kept alive an option of reprocessing all spent nuclear fuel in its proposal to the government after it faced opposition from the industry ministry and power companies to scrapping the long-standing fuel recycle policy, committee documents showed Saturday.
As part of the government's energy policy review process, the commission tasked with setting basic nuclear energy policies initially planned to propose in June that it would be "desirable" to change the full recycling policy, according to the documents seen by Kyodo News.
The documents suggest that the Ministry of Economy, Trade and Industry, which has aggressively sought expansion of nuclear power use, exercised its influence to resist a possible change to Japan's current policy to reprocess all spent fuel from nuclear reactors and recover plutonium for reuse.
Following the March 2011 Fukushima nuclear disaster, the government is considering reducing the portion of total electricity generated by nuclear power in 2030 to zero, 15 percent, or 20 to 25 percent, compared with 26 percent in fiscal 2010.
According to the commission documents and sources close to the matter, the commission initially planned to drop the option of reprocessing all spent fuel from its proposal under the scenario of 20-25 percent reliance on nuclear power.
In the proposal presented to the government, the commission said that both reprocessing and direct disposal of spent nuclear fuel should be pursued if nuclear reliance is to be cut to 15 percent or lower while recycling of all spent fuel is a viable option for the 20-25 percent scenario.
An industry ministry official overseeing the nuclear fuel recycling demanded that the commission's secretariat keep the option of full reprocessing in the proposal, telling it that consideration should be given to a local government in Aomori Prefecture which hosts various nuclear fuel reprocessing and radioactive waste storage facilities, according to the documents and the sources.
The Aomori village of Rokkasho recently decided to seek the removal of spent nuclear fuel accepted from across Japan if the central government gives up on the fuel recycling policy.
Power company employees working at the commission's secretariat also opposed scrapping the full recycling option, according to the sources.
A commission member said a unanimous agreement on the proposal could not be reached and the members decided to reflect the industry ministry's view on it.

Assembly members of the village of Rokkasho in Aomori Prefecture unanimously agreed Friday to seek the removal of spent nuclear fuel it has accepted from across Japan if the central government gives up on its long-standing fuel recycling policy.
The agreement came as Prime Minister Yoshihiko Noda's Democratic Party of Japan has proposed that the government pledge to bring an end to nuclear power generation in the 2030s in its new energy strategy, which will be finalized as early as next week, following last year's Fukushima nuclear disaster.
The village has allowed various facilities to reprocess nuclear fuel and store radioactive waste. But if the government decides to end nuclear power generation, there would be no point in pursuing fuel recycling.
The assembly called for the continuation of the recycling policy. But the assembly at the same time said in a statement that it is ready to remove the stored fuel from the village and resort to various other actions if the central government decides to withdraw from the recycling policy.
Japan has also sent spent fuel to France and Britain for reprocessing and has accepted nuclear waste created in the process. The statement said the village will not allow that waste to be brought in if the policy changes.
Regardless of whether the policy changes, a fuel reprocessing plant in Rokkasho, Japan's first such commercial facility, has not yet started full-scale operation amid repeated problems, even though nearly 20 years have passed since the beginning of its construction.
