Subject:
James A. FitzPatrick Nuclear Power Plant Docket No. 50-333 i
Proposed Changes to the Technical Specifications Regarding Main Steam Isolation Valve Closure Time (JPTS-87-013)
Dear Sir:
This application for an amendment to the James A.
FitzPatrick Technical Specifications proposes changes to the main steam isolation valve (MSIV) closure times.
The change I
would allow plant operation for the remainder of Cycle 8 with a minimum MSIV closure time of two seconds for one of the four steam lines.
The existing Technical Specifications require that 4
the main steam isolation valves close within three to five seconds.
Until this amendment application is approved, operation of the FitzPatrick plant will be limited to less than full rated power.
This operating restriction is an emergency situation as defined in 10 CFR 50.91(a) (5).
Therefore, the Authority requests that the review and approval of this application be conducted on an expedited basis as permitted by that regulation.
This situation was discovered during routine surveillance testing.
The "C" outboard MSIV closure time was found to be outside the Technical Specification limit.
The measured closure time of 2.3 seconds was below the minimum allowable closure time of 3 seconds.
In accordance with Technical Specification 3.7.D.2, an MSIV in the "C" steam line was closed thereby isolating the line.
The MSIV closure time could not be returned to within technical specification limits by normal adjustment of the hydraulic speed control system.
Adjustment of the hydraulic cylinder cannot be done without disassembly which requires a plant shutdown due to high temperature and high radiation in the area.
The valve will be adjusted at the next outage of sufficient duration.
To maintain steam line flows at a normal operational level, reactor thermal power was maintained at approximately 75%
rated.
A new analysis has demonstrated that FitzPatrick could

e run at up to full rated power with three steam lines in service.
Reactor power was then increased.
However, power is l
limited to approximately 92% and is being operated at 88% rated to maintain sufficient margin to the MSIV high flow isolation setpoint.
l Enclosed for filing is the signed original of a document 1
entitled " Application for Amendment to Operating License," with Attachments I and II thereto, comprising a statement of the proposed changes to Appendix A of the Technical Specifications and the associated Se^J.y Evaluation.
In accordance with 10 CFR 170.12, a check in the amount of
$150.00 is enclosed as payment of the application fee for the review of the proposed changes to the Technical Specifications.
In accordance with 10 CFR 50.91, a copy of this application and the associated attachments are being provided to the designated New York State official.
Should you or your staff have any questions regarding the proposed changes, please contact Mr. J. A. Gray, Jr. of my staff.
