"# ' Executive Vice President, Nuclear m m Gentlemen: I , SUBJECT: NRC INSPECTION OF PALO VERDE UNITS 1, 2 AND 3 + E This! 1etter refers to the routine inspection by Messrs. T. Chan of NRR, and . of this office, on May 16-18 and June 1 b Johnson,R.HueyandC.RamseyIzedbyNRCLicenseNos.NPF-41,NPF-51and 14-15,'1990, of activities author . L NPF-74, and to the discussions of our findings held with members of your-staf Areas examined during this-insoection are described in the enclosed inspection report.- Within these areas, tle inspection consisted of selective-examinations of: procedures and representative records, interviews with personnel, and observations-by the inspectors.

. ' I Based on the results of this inspection, it appears that several of your . , l' 'ac W ities were not conducted in full compliance with NRC requirements' as i' di s ssed in Paragraphs 3, 4, and 5 of the report. These apparent violations ,. will be the subject of separate correspondence. In accordance with 10 CFR 2.790(a), a copy of this letter and the onclosure will be placed in the NRC' Public Document Roo . We;are concerned about the apparent unreliable performance of.the Palo Verde 4 emergency lighting system, as evidenced by numerous failures'of emergency l L lighting system components. Excessive failuras and the adequacy of the J emergency lighting system design implementation were addressed by ANPP in LER 1 p 86-059. Problems have been identified in the emergency lighting _ system by_the j L NRC and by your staff since 1984. The same problems have continued to. exist L over a six year period, and were a topic of escalated enforcement action and a' L civil penalty documented in our letter to you dated September 1,1989 (EA-89-88). Furthermore, emergency lighting failure data originally provided to NRC inspectors in March 1990, needed to be revised on sever-1 occasions, with the most recent revision occurring on June 29, 1990. The need for repeated-L revision of this data appears to be another indicator of the need for greater L engineering and quality oversight involvement with the emergency lighting L syste I an As discussedconference enforcement between Mr J. been has N. Bailey arranged and myself for Julyon10, July 2,1990,iscuss 1990, to d the l results of this inspectio $$o-724S295 900705 I I I
