' OUTLINE

-The purposes 1and objectives-of this testimony are to. respond to three Board-questions? relating to UCS Contention 12.

The-

testimony shows that the:only environmental stress to which certain. safety-related: equipment at TMI-2 was exposed that was

> beyond: conditions for which it'was qualified was submergence'

'duerto flooding , and that appropriate corrective actions are being taken at TMI-1. ~ The: testimony also explains'whyLRegu-

- latory Guide 1.89 does not apply 1to TMI-1, and why the environ-mental. qualification investigation of safety-related. electrical equipment, ordered byithe Commission, provides reasonable assurance of safe operation at TMI-1. Finally, the testimony identifies the environmental qualification criteria which equipment inside of -containment must meet with . respect to radiati'onJ1evels;a'nd length of time of exposure.

INTRODUCTION

.g-"

This testimony,fby Mr. George R. Braulke,'GPU Senior Electrical Engineer,-is addressed to-the three Board Questions regarding Cc3 Contention No. 12. Each question is quoted below,. followed imme--

diately by Licensee',s response to.the question.

/

FIRST BOARD' QUESTION REGARDING UCS CONTENTION 12

- The TMI-2 accident demonstrated that some safety-related equipment may have been exposed-or was in imminent danger.

of being exposed to environmental-stresses beyond that for which it was qualified. The board's concern.is primarily with such equipment qualification. -In addition, environ-mental stresses to safety-related equipment will be of concern to the, extent that such equipment is not included in existing staff requirements.

1_ The Implementation section of Regulatory . Guide 1.89 states as'follows:

4 This guide reflects current regulatory' practice.

4 Th,erefore,' except in those c~ases in which the-applicant

? proposes.an. acceptable' alternative method for-complying 1: with specified portions of:the Commission's---regulations, this-guide---will;be used:by~the Regulatory l staff in

- evaluating-all.' construction permit applications for U which the-issue date.of the Safety Evaluation Report' (SER) -is July 1, 1974',- or after.

i s 'Forythose construction permit applications for which j an:SER was?is' sued priorito July.l',-1974, the. Regulatory

istaffemay,. subsequent to issuance of the' construction

. permit-(or operatingilicense)', .' reevaluate the Safety Analysis Report:on.a~. case-by-case.' basis to assure-that acceptable' methods for qualification of. Class:IE equip-

-ment have been specified.in. purchase orders executed 4

.TMI-I received:its operating licenseiin . April, 1974. Consequently, Regu1atory! Guide 11.89Ldoes-not applyr.to TMI-l'.-

. cation ~' investigation 1 initiated by IE Circular 78-08 and IE Bulle-tin 79-01, and performed byLLicensee, has' discovered no evidence-s

. to'date?upon which to conclu'de that this objective was not realized.

As stated by the Ccemission'in Petition for Emergency and

- Remedial Action,- CLI-80-21', 11 N.R.C. 707L(1980), the DOR Guide-

Llines and.NUREG-0588 provide more definitive criteria than Regu-latory Guide 1.89 for the environmental qualification'of safety-related electrical equipment. In that-same decision, the Commiss1on ordered the-use of'the DOR Guidelines, which provide a level of-confidence essentially equivalent to tdtat which would j

, be achieved :from; the application of IEEE-323-1974, to review j operating-plants,l'and NUREG-0588 to review plants under licensing 1 I

'the requirements 2which must be~ met in' order to satisfy those: l aspects o: Teral Design: Criterion'4 of Appendix A to-10 C.F.R.

PartJ50'which relate to environmental qualification of safety-relatedfelectrical equipment. The Commission ordered that by

'no laterfthan'JuneJ30,11982,- all. safety-related' electrical

' equipmenttiniall operating plants'sha11Lbe qualified to the

' DOR Guidelinescor NUREG-0588. _The commission further stated 4

that current NRC requirements and those actionsJordered in-CLI-80-21

. provide-reasonable-assurance th'at the public health and-safety is adequatelyLprotected during the tima necessary for corrective

' action.

The environmental qualification. investigation of safety-1

-related electrical equipment subjected to_possible harsh environ- l ments under IE Bulletin;79-01B will identify any components'that do not conform to cne DOR Guidelines or where adequate documenta- l tion 11s'not avai_able to demonstrate conformance. In such in- .j stances, corrective action will be taken in accordance with the 1

requirements of IE Bulletin 79-01B.

equipment inside of-containment must meet with respect I l to radiation levels and length of _ time of exposure? ~
