PMI-82/4172

On May 28, 1982, Mississippi Power and Light notified the NRC of a Potentially l ,

Reportable Deficiency (PRD) concerning setpoints for relief valves on the Fuel

! Pool Cooling and Cleanup (FPCCU) System Heat Exchangers.

On June 22, 1982, MP&L QA received a letter, PMI-82/3815 (dated 6/21/82), from MP&L Nuclear Plant Engineering stating that thic potential deficiency would not adversely effect the safety of operations of GGNS. On June 23, 1982, QA informed the NRC that MP&L had determined that this potential deficiency was not reportable under the provisions of 10CFR50.55(e). The PRD was withdrawn with the understanding that a formal report would be submitted if requested by

+

the NRC at a later date.

! On July 1, 1982, Mr. R. Butcher, NRC Region II, conducted an exit interview at GGNS. He informed MP&L that during his inspection he reviewed MP&L's

' rationale concerning the reportability of the deficiency. He stated that he believed the deficiency to be reportable and that MP&L should submit a formal report to the NRC. As a result, on July 2,1982 MP&L telephoned Mr. Butcher to request and was granted an extension for submission of a written report until July 9, 1982.

On July 7,1982, Mr. Butcher called MP&L QA and stated that per further conversations with members of the NRC Region 11 staf f, PRD-82/31 would not need to be reported to the NRC in a formal report. The PRD would, therefore,

, be considered withdrawn.

This PRD is considered closed.

The Fuel Pool Cooling and Cleanup (FPCCU) Heat Exchangers (Q1G41B001A&B) are l fitted with relief valves set in excess of the design pressure. The equipment

,t is designed under ASME Section III, Subsection ND (Class 3). ND-7511, Set i

Pressure Limitations, states that the set pressure of at least one pressure (1'

relier device connected to the system shall not be greater than the design pressure of the system at design temperature. GE Document 21A9520AB Rev. 7, i Fuel Pool Heat Exchanger Data Sheet, states the design pressure as 250 psig and 150 psig for the shell and tube sides of the heat exchanger, respectively. GE drawing VPF 5202-1-7 shows the set pressures at 275 psig and 165 psig. The vendor is Atlas Industrial Manufacturing Co., 81 Somerset
