4 AUG 0 s Jggs Docket No. 50-213 Mr. Edward J. Mroczka Senior Vice President Connecticut Yankee Atomic Power Company Post Office Box 270 Hartford, Connecticut 06141-0270

SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED REVISION TO TECHNICAL SPECIFICATION FOR LEAKAGE DETECTION SYSTEM - HADDAM NECK PLANT - (TAC #61329)

The NRC staff has reviewed ycur April 25, 1986 Technical Specification request and has determined that additional infonration is needed tc complete cur safety evaluation. Enclosed are our questions regarding this proposed Technical Specification.

The reporting and/or recordkeeping requirements contained in this letter affect fewer than respcodents; therefore, CMB clearance is not required under P.L.96-511.

If you have any questions or concients please contact me at (301) 492-1313.

s Sincerely.

v-Request For Additonal Infonnation Haddam Neck Plant Proposed Revision to Technical Specifications Leakage Detection Systems

1) The IPSAR stated the leakage detection systems could meet a sensitivity of I dgpm in I hour. Your current submittal states the leakage detection systems have a sensitivity of I gpm in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Please provide the sensitivity of the four leakage detection systems (Airborne Gaseous Radioactivity Monitoring System, Volume Control Tank (VCT) Level Monitoring, the Containment Instrument Sump and the Containment Main Sump Level Monitoring Systems) and analysis or data to demonstrate that sensitivity.

2) Do the leakage detection systems have any annuciation alarms to indicate that there is a leak?

3) Why was the Containment Atomosphere Gaseous Radioactivity Monitoring System excluded from the post-greater than one half SSE sur.eillance requirement?

4) Can the fonnat be changed to be more consistent with the STS? (See Attachment) 4 I
