Dear Mr. Beard:
SUBJECT:
CRYSTAL RIVER UNIT 3 - REQUEST FOR ADDITIONAL INFORMATION CONCERNING FLORIDA POWER CORPORATION'S (FPC) REQUEST FOR EXEMPTION FROM l'
APPENDIX R, SECTION 111.0. TO 10 CFR 50 (TAC N0. M86794)
By letter dated June 7, 1993, you requested an exemption to the oil collection requirements of Section 111.0. to Appendix R to 10 CFR 50. The subject exemption was requested in order to accommodate a new Reactor Coolant Pump
.(RCP) motor. The exemption is needed because four potential oil leakage sites-cannot be accommodated with the oil collection system as a result of design difficulties.
We have completed our preliminary review of your submittal' and we need additional information in order to complete our Safety Evaluation. Our request for additional information is enclosed.
o This requirement affects fewer than 10 respondents and,'therefore, is net.
subject to Office of Management and Budget review under P. L.96-511.
Please contact me at (301) 504-1475 if you have any questions concerning this letter.

4 Enclosure 1.
In order to properly assess the safety impact of a fire involving the oil associated with one of the RCP motors, please describe the consequences of a postulated oil fire involving the leak sites under worst case leak conditions.
Discuss what effects this would have on the integrity of the reactor coolant system (RCS) piping and pump seals.
2.
If an RCP motor oil fire were to occur, please explain how the plant and the fire protection features provided for the area of concern would respond to this condition.
For example, explain how the fire would be detected; what actions would be taken by plant operations; and how the fire would be controlled and extinguished.
Are the cubicles accessible for manual fire fighting?
3.
If a leak were to develop from one of the potential oil leak sites not covered by the RCP oil collection system, could oil leak on any hot RCS piping or lagging surfaces?
If there is a possibility of oil leakage contacting hot RCS piping or lagging, have these surfaces been shielded to direct potential oil leakage to a safe location?
4.
In order to quantify the magnitude of the fire problem, what is the quantity of oil contained in each RCP and what are the flammability characteristics of the oil (e.g., flash point, ignition temperature, heat release rate)?
In addition, please provide a description of the RCP cubical, including approximate floor areas, volumetric dimensions, and air flow rates through the cubical.
