NLS-89-137 United States Nuclear Regulatory Commission ATTENTION: Document Control Desk Washington, DC 20555 SHEARON HARRIS NUCLEAR POWER PLANT DOCKET NO. 50-400/LICENSE NO. NPF-63 SUPPLEMENT TO REQUEST FOR LICENSE AMENDMENT REFUELING OPERATIONS LOW WATER LEVEL Gentlemen:
Carolina Power
& Light Company hereby submits a supplement to the February 22, 1989 license amendment request regarding Specification 3.9.8.2, Refueling Operations
- Low Water Level which revises Surveillance Requirement 4.9.8.2 to delete the Residual Heat Removal (RHR) minimum flow requirement of 2500 gpm when the reactor water level is below the reactor vessel flange.
This letter revises Surveillance Requirement 4.9.8.2.2 to impose a minimum flow requirement: of 900 gpm when the reactor water level is below the reactor vessel flange.
Westinghouse performed an engineering evaluation to verify that a minimum RHR flow requirement of 900 gpm will provide sufficient mixing should a Mode 6 boron dilution event occur.
The revised Technical Specification pages, including both the marked-up and retyped versions, are included in Enclosure 1
~
The enclosed change is more restrictive than that originally proposed.
As such, the 10CFR50.92 Evaluation and the Environmental Evaluation provided in the Company's February 22, 1989 submittal remain valid.
Please refer any questions regarding this submittal to Mr. Mark A. Turkal at (919) 362-2985.
Yours very tr y,
ABC/MAT Enclosure.-
