Intervenor contends Applicant's reactor trip system is not protected againd a pipe break to the scram discharge volumis~ff6i:1'thT hy'dfaulic contiol' units. Sudden breakage of one or more of these pipes would impair public safety because the water would continue *come out of the reactor and possibly drown out, short or otherwise stop the recir-cultion cooling pumps which are located below them, and there is no valve upstream of such break locations to per-mit stopping the loss of coolant., A plausible physical mechanism for pipe break in this part of the control rod hydraulic system would be thermal shock to the non-safety grade piping. Such thermal shock results on a reactor scram.

This Contention-is based on the results of the investi-gation of the June 28, 1980, partial scram failure at the Brown's Ferrv, Unit 3, by the NRC Office for Analysis and Evaluation of Operational Data, authored by Carlyle Michael-son. T_he report was sent to the Commissioners on April 7, 1981, as recorted in the Washington Post, of April 8, 1981 on page A-9 (attached).

To the best of this Intervenor's knowledge the report was the first publication of discovery of the problem in -

the contention. IEtervenor believes the requirements of

.- - s-10 CFR 2.714 (i) and'(iv) are met by him at the threshold, that is, the timing of the report lays good cause for a late filing, and that there is indeed no other party rep-resenting his interest on this issue. In 10 CFR 2.714 (10 Intervenor believes it cannot be shown there is available (O at this time other means by which his interest will be ,

s dg6d protected on this issue. Under 10 CFR 2.714 (v), this 810 507 0 $ff

s . .

Intervenor would point out the final schedule for hearing sefety issues is not determined. Indeed, discovery on issues, while others are in litigation is permissible in

, a multi-issue administrative hearing, although not desir-able. In acy case it is not reasonable to deny an Inter-venor the ri-ht to hear an issue, because he won't have time to do discovery on the issue. Under 10 CFR 2.714 (iii) this Intervenor 1ould ou 7 urge that a record which does

~

not cover an issue cannot be complete as one that does even if the Intervening party does not present expert Ve'stimony.

Therefore, this Intervenor requests the Board admit into controversy his Contention #56, with discovery to begin at once.

Respectfully Submitted,

, I
