==SUBJECT:==
(UPDATE) TRANSFER OF SPENT FUEL FROM SPENT FUEL STORAGE POOL TO ONSITE INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI)
Vermont Yankee completed the transfer of the initial cask of spent fuel to the on-site Independent Spent Fuel Storage Installation (ISFSI) at approximately 3:00 pm on May 29, 2008.
No equipment problems were noted subsequent to the resumption of the spent fuel transfer activities on May 23, 2008. The spent fuel handling activities had been suspended following identification of a reactor building crane issue on May 12, 2008. Specifically, while lowering a spent fuel transfer cask, the crane operator attempted to stop movement of the crane when the transfer cask was approximately four inches above the refueling floor. However, the crane motion did not stop as expected, and the fuel cask continued to be lowered at the normal rate of speed to the refueling floor. The spent fuel transfer cask was set down on the refueling floor in an acceptable location and supplemental cooling was established per procedure. This issue did not have any impact on public health and safety.
Entergy conducted troubleshooting and attributed the crane problem to improperly calibrated relays that function to actuate the crane brakes. Entergy re-calibrated the affected relays, then retested the crane on May 22, 2008. The NRCs Resident Inspectors, as well as a specialist inspector from the NRCs Region I office in King of Prussia, PA, reviewed the crane troubleshooting activities. The adequacy and thoroughness of Entergys past maintenance of the reactor building crane continue to be reviewed by the NRC, and the results will be included in an upcoming inspection report.
The NRC continues to inspect activities associated with the ISFSI campaign. The information presented herein is current as of 10:00 a.m., May 30, 2008.
The NRC Region I office has communicated with the State of Vermont, the State of New Hampshire, and the Commonwealth of Massachusetts regarding the reactor building crane issue. This preliminary notification is issued for information only.
