;  Louisiana Power & Light Company ~ -2-p  Okonite'T95/35 taped splices, we have determined that LP&L has not provided
  'any additional information that would change-our position and is therefore in
,  violation of.' requirements. The basis for our determination of a violation is
  . discussed in.the following paragraphs.
 
'
s As presented in the June.1 Enforcement Conference LP&L's position was  !
that the Okonite splices were qualified for submergence. L'P&L supports this
.
position on the following bases:
<
  *
LOCA type steam testing followed by a 5 minute submergence test;
  *
A long-term submergence test of T95 insulation (without the jacket)
P,    in tap water;
  *-
y  'NRC acceptance of this LOCA type steam testing in Supplemental Safety Evaluation Report (SSER)-5, dated June 1583 and SSER-8 dated
      '
December 1984; .    ;
  "'
NRC acceptance of this type testing during hearings on the licensing.
 
~of'the Seabrook plant, and
  *
Co.coatibility of cable and splice materiil based upon a review of 'l proov t literature and qualification reports for XLPE-and.EPR insula nd cables.
 
NRC's basis for not sccepting the qualification of the splices for submergence is consistent with NUkEG-0588, " Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment," dated Ju~iy 1981. 1
  ' Paragraph 2.2 of NUREG&O588 requires equipment subject to submergence to be i
        '
qualified by. test. These test conditions must represent the environment,a1 conditions to which the equipment will.be subjected. The LOCA type steam test l and the long-term submergence in tap water test do not meet the requirements i of NUREG-0588~1n that they do not reflect the actual environmental conditions j to which the splices would be subjected. Additionally, a test conducted on one 1 type of. splice (e.g.. an Inline splice) cannot be extrapolated for a different l
        "
type of splice. Your staff was informed of this position in numerous discussions with NRC inspection and staff personnel'.
I At the time of the EQ Audit in January 1983, the submergence qualification of J Okonite splices was discussed. The LP&L response to the audit finding was that i no splices would be located below the fhod level and that a construction
  ~
l procedure would be revised to prohibit splices below the flood level. l
    '
SSER-5, which addressed this EQ Audit, specified that equipment subject to submergence.would be qualified for submergence in accordance with NUREG-0588. ,
        '
SSER-8 closed out the EQ issues identified in the EQ Audit based upon the NRC understanding that equipment qualification at Waterford-3 was in accordance with 10 CFR Part 50.49 and NUREG-0588 and that no equipment would be subjected )
to submergence. These SSERs did not change the NRC position on submergence qualification.

We acknowledge that the equipment submergence issue addressed during the Seabrook nuclear plant licensing hearing may have been a point of confusion with your staff. However, the numerous discussions between the NRC and your staff, which included the NRC staff members involved in the hearings, should have clarified this decision.
of Meeting:
Location of Meeting: NRC Region IV office, 8th Floor Conference Room Purpose of Meeting:  Enforcement. Conference to discuss potential violation associated with the environmental qualification of-submerged splices (NRC; Inspection Report 50-382/89-05)and-environmental qualification of submerged cables (identified during a followup conference call between NRC RegionIVandLP&L).


We note further discussion of this decision in Appendix B of your June 21 ,
NRC Attendees:  L. J. Callan, Director, Division of Reactor Projects .(DRP J. L. M11hoan, Director, Division of Reactor Safety.(DRS))'
letter. The NRC position remains that the issue was decided only because the licensee (for Seabrook) informed the hearing board that no equipment would be

located below the postulated flood level.


We note that LP&L had tested Okonite splices for submergence on EPR type cable. As we discussed earlier in this letter, the NRC position is that this testing does not provide qualification because it does not reflect the actual environmental conditions to which this splice configun. tion would be subjected. Additionally, as was discussed in the June 1 Conference, the testing of one manufacturer's.EPR type cable does not provide qualification for other manufacturers' EPR type cables. Furthermore, since your Okonite splices are used on other. types of cables (e.g., neoprene and Tefzel), the NRC position remains that to qualify these splice configurations for submergence requires a submergence test that duplicates the actual environmental conditions. This position is consistent with the provisions of NUREG-0588.

We conclude that a violation of 10 CFR Part 50.49 with respect to the submergence qualification of Okonite T95/35 taped splices did occur. Based upon our '
  . - _ - _ _ _ _ _ . - _ _ _ _
understanding that the equipment affected by the submerged splices have redundant qualified substitutes that are not subjected to submergence, the condition does not meet the criteria for escalated enforcement action. Our understanding is based upon your submittal of a Justification for Continued Operation on February 23, 1989.
