Dear Mr. O'Reilly:

This facsimile confirms the conversation between Mr. A. C. Tollison, Jr.,

BSEP General Manager, and Mr. P. J. Kellog, of your office, at 0945 on October 15, 1980.

4 In reviewing the Containment Atmospheric Dilution (CAD) syst.am in response to item 2.1.Sa of NUREG-0578, Carolina Power & Light Cenpany has determined that a relay exists in the logic circuit for both Brunswick Units which does not meet the single active failure criteria of the CAD system as stated in the FSAR. A failure of this relay, located in the containment isolation override logic circuit, could prevent post-LOCA nitrogen injection due to the inability to remotely operate the injection valves CAC-VS, V6, V47, V48, V55, and V56.

h\ t 8910210 66 7 "J

O Mr. J. P. O'Reilly October 15, 1980 The FSAR states that nitrogen injection will not be required until approxi-mately ten hours after a LOCA event with fuel damage to control the oxygen concentration. To ensure that nitrogen injection can be accomplished when required with this relay in the failed condition, the operating procedures describing injection are being revised to advise the operator to check the status of this relay should the injection valves fail to open. The pro-cedures will also include instructions for jumpering the relay _ contacts to their appropriate position for valve operability with available predesignated jumpers. A plant modification which is being prepared in response to NUREG-0578 and scheduled to be completed on both units by late 1981 will provide a permanent correction to this problem.
