his letter is written to respond to the item of apparent nonceepliance Adentified in IE Inspection Report 050-155/76-01. trans itted by'your letter.
dated February 13, 1976.
Your letter stated that corrective action with respect to Infraction 1 had, been completed in a ti=ely canner and that you had no ftether questions at this time. Additional response was requested with respect to Infraction 2.
This infraction was:
"2.
Contrary to 10 CG 50.59, safety evaluations were not con-ducted as required prior to performing construction activities relative to the following plant modifications involving safety-related equi;=ent.
The fire protection system sprinkler header was modified a.
on October 2h,1975, without prior review and documented l
safety evaluation.
(Paragraph 1.e, Report Details II) b.
Construction activity on Dece=ber 19, 1975, ' concerning excavation between the turbine building and.the contain-ment building resulted in damag e to the turbine building ventilation exhaust line while the reactor was operating.
No reviev snd documented safe',y evaluation was perfor=ed preceding this activity.
(Peragraph 1.f Report Details II)"
( The occurrence associated with the fire ;rotection sprinkler header was reported as A0-26-75 transmitted by letter dated November 2h,1975
- de believe that the corrective action specified for this occurrence, which is the same as that specified in A0-2h-75 is adequate corrective action.
7/g/2A#AAfe occurrence associated with excavation between the turbine building and the containment building was reported as A0-30-75 transmitted by our letter-
2 4
t effort was being expended at the time when the occurrence took place. Based on the analysis of the cause of Ao-30-75, two r.dditional engineers at the f ant have been assigned to review the extensive construction activities dur-l ing the present outage on a. continuing basis and. perform the reqaired safety evaluations per 10 CFR 50 59 We feel that our interim effort in reviewing
. all propased, faci'Aity chseges cno work packages associated with major facility changes as co==itted 'in response to A0-2k -75 and expanded following A0-30 is adequate.
The four similar occurrences are of concern to Consu=ers Power Co=pany. We note, however, there vere,very subtle differer.ces in each of these occurrences and believe that we have developed at least interi= procedures which vill pre-clude'their recurrence in the future. Further, verk is being done in the General Office in an atte=pt to better define the problems and their per=anent solutions such that less cu=bers0=e per=anent procedc es may be i=ple=ented.
