Watts Bar Nuclear Plant, Unit 1 - Withdrawal of License Event Report 390/2011-003, "Mode Change without meeting Limiting Condition for Operation (LCO) 3.7.5"

The following is a letter from TVA that requests a retraction of an LER. Do you agree or disagree with the justification?

On June 24,2011, the Tennessee Valley Authority (TVA) submitted Licensee Event Report (LER) 390/2011-003, "Mode Change without meeting LCO 3.7.5." The LER was reported as a condition prohibited by technical specifications in accordance with WBN License Condition 2.G.

This letter is being submitted to withdraw LER 390/2011-003.

LER 390/2011-003 described a condition where the plant entered Mode 3 with an inoperable auxiliary feed pump turbine (AFPT) in violation of LCO 3.7.5 and LCO 3.0.4. LCO 3.7.5 states three (3) trains of AFW are required in Modes 1,2, and 3 and that one (1) train of AFW is required in Mode 4 when the steam generator (SG) is relied upon for heat removal. LCO 3.0.4 prohibits Mode changes when an LCO is not met under certain conditions that were not applicable to this event. Upon further review, TVA determined that LCO 3.0.4 was not violated for the following reasons.

India - The Kudankulam stand-off: A way out - Comments from the former Chairman, Atomic Energy Regulaotry Board.

Protests against the two Russian VVER nuclear reactors being built in Kudankulam were low key all along, but after the Fukushima accident, this opposition has gained momentum. The major reason for the opposition was always the concern for the safety of the Russian reactors and the fear that their operation will severely reduce the fishing potential in near-coastal waters. But, of late, these protests appear to be widening into a struggle to oppose nuclear power plants in general, and not just the Russian VVERs. This is reflected also in the composition of the Advisory Expert Panel recently formed by the People’s Movement Against Nuclear Energy, which includes some established anti-nuclear activists. This transformation does not augur well for the future of India’s nuclear power programme.

The construction of the first unit at Kudankulam started in March 2002. Under this contract, the Russians are committed to supply the enriched fuel for the lifetime of these reactors and India can keep the spent fuel and reprocess it when we wish. These terms are quite liberal and different from the stringent controls the Americans imposed in 2008 under the Hyde Act and the 123 Agreement.

To secure the India-US nuclear deal, our prime minister gave a unilateral assurance to the US, France and Russia that — subsequent to the Nuclear Suppliers Group granting exemption to India — we shall purchase a sizeable number of nuclear reactors from these three countries. It is to fulfill this promise that the government is aggressively pursuing a policy of reactor imports.

Workers return to Nebraska nuclear plant closed by flooding

 OMAHA, Neb | Mon Aug 15, 2011 1:29pm EDT

 (Reuters) - About 120 Fort Calhoun Nuclear Station employees moved back into the flooded plant's administration building on Monday.

 The plant, which was idled April 9 for routine refueling and maintenance, remained shut down this summer after Missouri River floodwater spread across the riverside site near Blair, Nebraska, in June.

 The river has dropped about two feet since its crest, allowing workers to dismantle elevated walkways and parking lots to reopen at the 478-megawatt plant.

Top nuclear regulators fired over Fukushima political fallout

JAPAN’S GOVERNMENT has sacked the nuclear industry’s top regulators in another bid to stem the political fallout from the world’s worst nuclear accident since Chernobyl, 25 years ago.

The move follows revelations that the supposedly neutral Nuclear and Industry Safety Agency had secretly worked with utilities to rig public discussion on restarting reactors.

Trade and industry minister Banri Kaieda said he wanted to refresh and revitalise...

Nuclear Power Is Extremely Safe -- That's the Truth About What We Learned From Japan

In the midst of a still struggling and fragile global economy, Germany has announced that it will shut down seven nuclear plants by the end of the year--which means that Germans will be left to run their factories, heat their homes, and power their economy with 10% less electrical generating capacity. Nine more plants will be shut down over the next decade and tens of billions of dollars in investment will be lost.

SEQUOYAH - OVERFLOW OF CONDENSER CIRCULATING WATER

Tags:

"At 0023 on 07/13/2011, a notification to an outside state agency, Tennessee Department of Environment and Conservation (TDEC), was made due to an overflow of Condenser Circulating Water from the northwest corner of the diffuser pond through a heavily vegetated area into a slough adjacent to the Sequoyah Training Center. Condenser Circulating Water is also discharging to the river via storm water outfall 14 near the cooling towers as well as the normal diffuser pond discharge at outfall 101.

"At approximately 1545 on 07/12/2011, one of the two diffuser gates at Sequoyah failed and shut off the west diffuser pipe. The other diffuser remained open throughout the event. Plant personnel made several attempts to raise the diffuser gate utilizing divers and cranes. When it was determined the crane could not lift the diffuser gate, both units reduced power to 85% and one (1) Condenser Circulating Water pump for each unit, two (2) pumps total, were removed from service. Diffuser pond level is currently lowering."

Senator Murkowski unveils bill to create interim nuclear storage sites

Tags:

Washington (Platts)--1Jul2011/107 pm EDT/1707 GMT

To fill the nuclear storage void that withdrawal of the Yucca Mountain storage site has created, the top Republican on the US Senate Energy and Natural Resources Committee introduced late Thursday a bill to create two temporary storage sites for spent nuclear fuel. 

The bill, by Alaska Republican Lisa Murkowski and co-sponsored by Louisiana Democrat Mary Landrieu, is intended to provide interim nuclear waste sites to end the current practice of storing most spent fuel onsite at nuclear power plants. 

"This proposal addresses one of the most glaring failures of our national nuclear policy--what to do with the used nuclear fuel currently that is currently being stored at over 100 sites across the country," Murkowski said. "This legislation makes good on the federal government's promise to provide a solution to the storage question."

Can Shumlin’s Arguments Against Vermont Yankee Pass the “Sniff Test”?

This Week in Nuclear

by John Wheeler

The State of Vermont and their Governor Peter Shumlin want to shut down Vermont Yankee Nuclear Plant.  Unfortunately for their cause, only the Federal Government, in this case the Nuclear Regulatory Commission has the legal authority to regulate nuclear plant safety.  In March the NRC granted the plant permission to operate for another 20 years.

Shumlin and his followers don’t like that.  They really want the plant shut down.  In fact, it will be a major political defeat for Shumlin if he looses this fight against the evil foreigners from Louisiana.  Plus, if he fails, he’ll renege on a campaign promise he made to all the anti-nuclear activists that gravitated to his cause.
