SUBJECT:

WITHDRAWAL 0F IN-SERVICE TEST RELIEF REQUEST N0. 30 - DAVIS-BESSE NUCLEAR POWER STATION In response to Open Item 50-346/80-19-03 in Inspection Report 80-19 (August 12,1980), Toledo Edison Company (TED) submitted a request for exemption from certain requirements of Appendix J to 10 CFR 50 on August 15, 1984 (Serial No. 1068). This item concerned testing of Decay Heat Removal System lfne valves DH-11 and DH-12 on Penetration 29 per the requirements of 10 CFR 50, Appendix J, Sections III.A.I.d and III.C. Further review of this open item identified that DH-11 is specifically exempted from Type C testing per Technical Specification 3/4.6.3 (Table 3.6-2). Valve DH-12 is not a containment isolation valve and, therefore, also exempt from the Type C testing requirements of Appendix J.

i Although the valves are exempt from the Type C testing requirements of Appendix J, the exemption requires a demonstration that the integrity of the DHR System line is being maintained. Consequently, Toledo Edison Company has modified test procedure ST 5051.03, Low Pressure Injection and Containment Spray Systems Leak Rate Test to include visual inspection and significant leakage measurement of the portion of the DHR System line from the external containment wall to valves DH-1517 and DH-1518 located outside of containment.

Valves DH-1517 and DH-1518 are included in the leakage testing under Surveillance Test procedure ST 5051.03. ST 5051.03 is conducted pursuant to Technical Specification 4.5.2.d.3 which limits Decay Heat Removal System leakage to 20 gallons per hour.

We have reviewed the applicable part of ST 5051.03 and consider it to be acceptable. Consequently, thq TED request that the relief request be withdrawn is granted.

Sincerely, ecc:c n.", m:w LT JU. .A. M % :.*
