NRC Reoortability Evaluation (Cont'd)
-(
i.
5 The Rogovin Comittee, which had previously requested a list of all PSC's submitted to Licensing since 1974, has requested copies of the PSC's for 39 of these concerns; these PSC's have been assembled and submitted to that Comittee by Contracts-Legal.
6.
A Special Audit was conducted by an HRC Inspector from the Region IV I&E Office on compliance with the requirements of 10 CFR 21.
In the exit interview with B&W personnel, sumarizing the results of the inspection, the NRC Inspector described two findings that he would recocraend to his superiors for review, as follows: (1) a deficiency in procedure NPG 1707-01 that implements Part 21 in that the procedure allows for BW notification of the affected utilities prior to notification of NRC, rather than immediate direct notification to the NRC by B&W, and also that the procedure -
does not address a, timely schedule for the evaluation of deviations; (2) an infraction in that a potential safety concern identified in a B&W memo by B. M. Dunn dated February 9,1978 did not result in the origination of a PSC form as required by procedure NPG 1707-01.
The NRC Inspector explained that these findings are preliminary.
pending review and appnsval by headquarters; if these findings were to be approved. B&W would be given the opportunity for responding.
There are three levels of findings that NRC can determine against a regulation such as Part 21: a violation, an infraction and a deficiency, in descending order of severity; only a violation can carry a civil penalty. Thus, the two findings, if finalized, would not carry a civil penalty such as a fine.
7.
Revisions have been proposed for pn)cedure. NPG 1707-01, " Process-ing of Safety Concerns", as follows:
(a) the sefinition of a safety concern has been bror.dened to provida for the filing of a PSC form for concerns that are not necessarily reportable inder 50.55(e) or Part 21; (b) an additional type of safety concern has been identified: this concern is inadequacies or errors in operating procedures or training that could affect safe planti operation; (c) the procedure requires that a scoping meeting be convened shortly after receipt of a PSC by 1.icensing to prioritize ting 1150 O

upgrade of Anticipatory Reactor Trip was completed and forwarded to the 177 owners.
Responses to Questions 1-4 and 5-8 went out 9-28-79.
Response to Question 9 went out 10-1-79.

problems i
, [
A. Anticipatory Reactor Trips
[
As indicated in I.D.2, B&W provided responses to the NRC request for additional information on anticipatory trips. One problem alen
/
-associated with our responses was that we could not provide suitable
[
justification that low OTSG inventory would not be anticipatory at
^
low powers. The net result is that Licensing believes a low OTSG f f inverstory trip will be required by the NRC. Licensing will provide its reconnendations for further actions on this subject by 10/10/79.

Statistical Core Desion The Statistical Core Design pmgram (topical) is still progressing in certain areas. However, it is losing gmunc. in the Thermal Hydraulic Unit where delays caused by higher priority work sn ATWS will cause an overall delay in the topical report submittas date. The exact magnitude of that delay is unclear at the present tinw.
E.
Toledo Edison Reactor Trips Two recent reactor trips caused loss of pressuri:ce level at Toledo Edison in Septesber. The NRC has not been able to put manpower on this concern because of their own manpower limitations. However, in the near' future, they can be expected to come down hard on us because of the " bucking bronco" syndrome. This area of concern does not appear to be receiving sufficient effort at B&W. Work is presently concentrating on the Auxiliary Feedwater control System which is only one aspect of the problem.
It is suggested that the concern be escalated to higher levels of management.
