UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION BEFORE THE ATOMIC SAFETY AND LICENSING BOARD i

In the Matter of S

S HOUSTON LIGHTING & POWER S

COMPANY S

Docket No. 50-465 S

(Allens Creek Nuclear S

Generating Station, Unit S

No. 1)

S APPLICANT'S MOTION FOR SU.NDIARY DISPOSITION ON INTERVENOR MC CORKLE'S CONTENTION NO. 17 i

Applicant moves the Board under 10 CFR S 2.749 to grant summary disposition with respect to Intervenor McCorkle's Contention No. 17 relating to containment leakage.

As shown

~

in the accompanying statement of material facts as to which there is no genuine issue to be heard, and the affidavit of r

Guy Martin and Walter Malec, there is no genuine issue to try in this proceeding and Applicant is entitled under S 2.749 to have the Contention summarily dismissed as a matter of law.

The Centention McCorkle's Contention No. 17 states:

The containment as designed will allow exces-sive leakage to bypass the filtration systems.

The Power company admits that 20 percent of the leakage would not even be filtered.

8008100349 527 i

Arcument In Contention No. 17 Intervenor McCorkle alleges that the ACNGS containment is designed to allow 20 percent of the leakage to bypass the filtration systems.

As the attached affidavit demonstrates, the containment design does not allow 20 percent of leakage to bypass the filtration i

system.

Intervenor's concern apparently stems from an outdated statement in the original SER Section 6.2.3, p. 6-29.

(Deposition Tr. 26)

This statement, however, does not reflect the design modifications to the ACNGS leakage preven-tion systems described in PSAR Section 15 and Appendix 15A.

As the attached Affidavit demonstrates, unfiltered containment leakage will be far below the percentage alleged by the Intervenor.

The Applicant has analyzed the potential leakage pathways through containment penetrations and, under design basis accident conditions, the amount of leakage which will be expected.

The latter (the design leak rate) will be 0.5 percent by weight of the contai,ned atmosphere per day at peak pressure.

This will limit off-site doses in the event of an accident to well belcw 10 CFR Part'100 allowable limits.

Applicant's analysis further estimates that, of the total amount of containment leakage, only.0195 percent per day of containment atmosphere will be unfiltered.

This will result in total unfiltered containment leakage far below the 20% claimed by intervenor.

Finally, extensive pre-operational testing will be performed in accordance with the requirements of 10 CFR, Appendix J, to ensure actual containment leakage is within j

NRC requirements.

s Accordingly, Intervenor McCorkle has not raised a genuine issue of material fact to be heard on this 1; sue and Applicant is entitled to summary disposition as a mitter of j

i j

law.
