Enclosure REQUEST FOR ADDITIONAL INFORMATION CATAWBA NUCLEAR STATION 00CKETS 50-413/414 1.
Administrative Controls (a) Describe the qualification requirements for the position of Superintendent of Station Services.
(b) Justify your statement in the July 31, 1985, submittal that the Operating, Technical Services, Maintenance, and Integrated Scheduling Superintendents have the same qualifications in view of their different functions and responsibilities.
(c) Clarify your statement in the July 31, 1985, submittal that the Operating, Technical Services, Maintenance, and Integrated Scheduling Superintendents each have the same authority.
2.
Electrolyte Leakage Your justification for deletion of the requirement to check for electrolyte leakage in Surveillance Requirement 4.8.2.1.la.3) is based on the surveillances already required for battery cell electrolyte level in Table 4.8-3.
- However, the staff's concern, as given in section 8.3.2 of the Catawba SER (page 8-11, second full paragraph), was that the electrolyte leakage might cause a dis-charge path through the metal battery rack which would go undetected on the de system ground detection because the racks are ungrounded. The staff recognizes that both the concerns for maintaining battery electrolyte level and discharging a cell could be alleviated by making the checks called for in Table 4.8-3, Category A, of the Catawba Technical Specifications. These checks, however, are only required on the battery pilot cells which may not be the cells that are leaking. Duke Power should, therefore, identify what surveillances are available to ensure a leaking battery cell is still operable or propose a change that would call for perfonning the Table 4.8-3, Category A, surveillances on any cell that shows signs of electrolyte leakage.
Considera-tion, however, should always be given to replacing a leaking battery cell, regardless of the results of such a surveillance, to ensure the continuing availability of the battery.
