May 3, 1988 Docket No. 99900403 MEMORANDUM FOR:

Marvin W. Hodges, Chief Reactor Systems Branch Division of Engineering and Systems Technology FROM:

James C. Stone, Acting Chief Vendor Inspection Branch Division of Reactor Inspection and Safeguards

SUBJECT:

GE'S EVALUATION OF POTENTIALLY REPORTABLE CONDITIONS (PRC) FOR 10 CFR PART 21 REPORTABILITY

REFERENCE:

1) Memorandum from M. W. Hodges to E. W. Merschoff dated May28,1987,2) GE letter MFN-018-88 dated March 7, 1988,

3) GE letter M/G 622 dated August 21, 1987, and

4) J. G. Partlow to GE letter dated November 6,1987 In our letter dated November 6,1987, we requested GE to review the NEB 0 master file of Potential Reportable Conditions (PRC) initiated during the past three years including any instances where they applied the Monticello bounding calcula-tions to conclude that the events were not reportable. GE's response dated March 7, 1988, identifies a PRC relative to a specific failure mode that was identified for the Turbine Pressure Control System which if encountered at partial reactor power (80%), could result in a Maximum Critical Power Ratio 4

(MCPR) below the technical specification safety limit. GE's response is attached.

Please review this letter and infonn us of the acceptability of the GE statement that the MCPR safety limit applies only to events occurring at moderate frequency which would exclude the above event and that the above postulated accident will result only in small radiological consequences.
