ATTACH?-1ENT ADDITIONAL RESPONSE TO BULLETIN 88-04
. SALEM GENERATING STATION DOCKET NOS. 50-272 AND 50-311 IN PSE&G's follow-up response to Bulletin 88-04, dated April 11, 1989, the vendor recommended recirculation flow rates for the RHR pumps were provided.
In further discussions with Ingersoll-Rand, PSE&G was informed that the recirculation flow rates were being extended as a result of Ingersoll-Rand's evaluation of industry feedback.
The new vendor recommended recirculation rates were transmitted to PSE&G in Ingersoll-Rands letter of June 7~ 1989.
The new flow rates provided are as follows:
(A) 100 gpm minimum for pump operation of 30 minutes or less; (B) a minimum flow rate of 300 to 500 gpm for pump operation of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> or less i- (C) a minimum flow rate of 1000 to 2000 gpm for continuous pump operation (operation exceeding 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> in a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period).
The RHR pump recirculation lin~s provide 500 gpm* flow for each RHR pump at Salem.
Therefore, RHR pump recirculation is not a concern for operation of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> or.less.
Procedures OP-II-1.3.6, "Draining the Reactor Coolant System", OP-II-6~3.2, "Initiating Residu_al Heat Removal" OP-II-6.3.3, "Terminating RHR", SP(0)4.0.5-P-RH11(21) and SP(0)'4.0.5-P-RH12(22), "Inseriice Testing for Residual Heat Remova'i", presently have been revised/verified to include precautions to ensure operation of the RHR pump in accordance with the vendor's recommended minimum specifications at reduced flow conditions.
Additionally the Emergency Operating Procedures (EOPs) have been reviewed to ensure that they adequately preclude operation of the pumps at reduced flow for longer than the recommended durations.
