REQUEST FOR ADDITIONAL INFORMATION REGARDING THE PROPOSED TECHNICAL SPECIFICATION CHANGE FOR THE MAIN STEAM SAFETY VALVE SETPOINT TOLERANCES FOR THE PALISADES PLANT (TAC NO. M91483) ear Mr. Haas:
B p y letter dated January 13, 1995, you submitted a proposed change to the alisades Technical Specifications (TS) to revise the required settings and llowable "as found" and "as left" tolerances for the primary and secondary afety valves.
The proposed limits would allow installed primary and a

e have completed our initial review and request that you provide additional nformation, as discussed in the enclosed Request for Additional Information RAI), so that we may complete our review. A response to the RAI is requested ithin 2 weeks from the date of this letter so that our review may be ompleted prior to the beginning of the upcoming refueling outage.
Please all me at (301) 415-3267 if you have any comments or questions.

REQUEST FOR ADDITIONAL INFORMATION REGARDING PALISADES PLANT PROPOSED TS CHANGE ON THE MAIN STEAM SAFETY VALVE SETPOINT TOLERANCES The NRC has completed its initial review of your letter dated January 13, 1995, on the proposed TS change for the Palisades main steam safety valve setpoint tolerances, and requests additional information as follows:
- 1.
Your request proposes that the primary and secondary safety valves be returned to within +/-1% of the nominal settings only if the valves are removed from the piping for maintenance or testing. However, the staff position is that the valves should be reset to within +/-1% anytime they are found outside this range in order to preclude setpoint drift which could continµe outside the analyzed +/-3% range.
You are requested to provide justification for not resetting the valves by demonstrating that continued drift beyond the +/-3% range would be acceptable or, alternatively, propose that the valves always be reset to within +/-1%
after any action that reveals they exceed the +/-1% criterion prior to returning the valves to service.
- 2.
Your request proposes to replace TS 3.l.7a and 3.l.7b with regard to operability of the primary and secondary safety valves. Currently, TS 3.l.7a and 3.l.7b do not contain a specific action statement if either TS cannot be met.
As a result, TS 3.0.3 would be entered which states, in part:
"When a Limiting Condition for Operation and/or associated -action requirements cannot be satisfied because of circumstances in excess of those addressed in the specification, within one hour action shall be initiated to place the unit in a condition in which the Specification does not apply by placing it, as applicable, in:
I.
At least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />,
- 2.
At least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and
- 3.
At least COLD SHUTDOWN within the subsequent 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />."
The time limits of Specification 3.0.3 allow 37 hours4.282407e-4 days <br />0.0103 hours <br />6.117725e-5 weeks <br />1.40785e-5 months <br /> for the plant to be in cold shutdown when a shutdown is required during power operation.
However, your proposed TS 3.1.7 would allow 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for the plant to be in hot shutdown and 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> for the plant to be in cold shutdown.
The time limits of the proposed TS are less conservative than those currently required by TS 3.0.3.
You are requested to provide justification with regard to the reasons for the change in time limits as well as the basis for acceptability.
