TECHNCIAL SPECIFICATION REQUIRED SHUTDOWN DUE TO INOPERABLE HPCI
At 2259 EST, Susquehanna Unit 1 commenced a TS Required shutdown for High Pressure Coolant Injection (HPCI) T.S. 3.5.1. Due to a suspected steam leak, the HPCI Inboard Steam Supply Valve HV155F002 was closed to attempt to identify and isolate an unknown drywell leakage condition. After closing the HV155F002, a detectable change in drywell leak rate occurred, therefore, HV155F002 was left closed. Closing HV155F002 makes HPCI INOP and UNAVAILABLE.
TS 3.5.1 was entered for this condition on 2/25/2011 at 2136 EST. LCO completion time for T.S. 3.5.1 entry is 3/11/2011 at 2136 EST.
The licensee has notified the NRC Resident Inspector and State authorities. The licensee also anticipates issuing a press release.

Twenty five years after the explosion and fire at the Chernobyl nuclear power plant, a United Nations report estimates the disaster caused thyroid cancer in more than 6,000 children in the affected area.
The world's worst nuclear accident caused thousands of cases of thyroid cancer among children, largely from drinking contaminated milk, according to a report by the U.N. Scientific Committee on the Effects of Atomic Radiation.
Annually, the Susquehanna River Basin Commission (SRBC) is required to adopt a Water Resources Program that identifies water projects and programs planned by SRBC, federal, state and local agencies and non-profit and for-profit interests to meet various water resource needs in the Susquehanna River Basin.
I am contacting your agency, organization or business to request input to SRBC’s 2011 Water Resources Program. Specifically, SRBC is seeking to catalog projects (facilities, plans and programs) expected in the 2011 – 2012 period. You can view and download the 2011 Water Resources Program response form at http://www.srbc.net/planning/water-resources2011.htm . This form contains instructions for completing and submitting responses by April 1, 2011.
As you may know, SRBC relies on the Water Resources Program to implement the 74 actions listed in the agency’s Comprehensive Plan. While the 2011 Water Resources Program response form includes many actions, you are asked to consider only those that apply to your agency, organization or business for the 2011 – 2012 period.
Thank you for your consideration of this request. I encourage your participation. If you have any questions or need additional information on this matter, please contact Mr. David Heicher of my staff. He can be reached at email@example.com or (717) 238-0423 ext. 110.
Many government and non-governmental entities participate in SRBC’s Water Resources Program each year. Should you wish to review the final 2010 document, it is available at http://www.srbc.net/planning/2010WaterResourcesProgram.pdf or by contacting Mr. Heicher for hard copies.
From the Brattleboro Reformer:
If you can't refute the message then try to discredit the messenger.
That's the tactic several Vermont Yankee advocates have taken to impugn the character and devalue the experience of Arnie Gundersen, a nuclear safety advocate who has been highly critical of the operation of the nuclear power plant in Vernon.
The writer of Atomic Insights (atomicinsights.blogspot.com) accused Gundersen of inflating his resume, which states he is an engineer with more than four decades of experience in the nuclear power industry.
Gundersen was a licensed nuclear engineer but has not been recertified in many years, though he claims he has spent 20 years working directly in the nuclear industry and led teams of engineers dealing with nuclear reactors at 70 nuclear power plants around the country.

The Vermont congressional delegation today urged the U.S. Nuclear Regulatory Commission to ensure a swift cleanup at Vermont Yankee after the license to run the nuclear power plant runs out.
Sen. Patrick Leahy (D-Vt.) and Rep. Peter Welch (D-Vt.) signed a letter that was drafted by Sen. Bernie Sanders (I-Vt.). Sanders sits on the Senate panel that oversees the NRC, which regulates commercial nuclear plants in the United States.
The lawmakers called it “unacceptable” that Entergy, which owns the Vermont plant, could engage in “decades of delay” before cleaning up the site along the Connecticut River at Vernon, Vt. “Immediate decommissioning will assure Vermonters that the plant is being disassembled safely,” the delegation wrote. An immediate cleanup and shutdown of the site also would allow the plant operator to take advantage of the skills of many long-term Yankee employees who otherwise would lose their jobs.
