REAUDIT OF THE ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENI AT THE ENRICO ttRMI ATOMIC POWER PLANT, UNIT N0. 2
1.0 INTRODUCTION
On December 14-18, 1981, a team comprised of representatives from the NRC staff and EG&G Idaho, Inc. conducted a re-audit of environmental quali-fication of safety-related electrical equipment at the Enrico Fermi Unit No. 2 Power Station. The initial audit (performed on July 13-17, 1981 and reported by EGG-EA-5534, August 1981) indicated that the Enrico Fermi Envi-ronmental Qualification program was incomplete. The work effort consisted of:
(1) a pre-audit review of the licensee's submittal, (2) an audit of the licensee's central files for selected items, and (3) a visual inspection of the installed equipment items for which the central files were audited. A table that shows equipment qualification status is provided in Appendix A.
Summaries of the central file reviews are provided in Appendix B.
2.0 EVALUATION The audit indicated that four of 150 equipment items are qualified.
This accounts for 27 of approximately 1500 Plant Identification System (PIS) component numbers. To complete the qualification program, the Detroit Edison Company (DECO) has comitted to testing 81 equipment items and replacing another 65 equipment items.
If any part of the testing or replacement program has not been completed by two months prior to fuel load, DEC0 will submit justification for interim operation.
There are two items of concern remaining as a result of the site visit.
First is the question of safety-related cables in conduit, subjected to sub-mergence. There are cable pull boxes that either need to be qualified for submergence or they cannot be considered as a protection against submer-gence. DECO has stated that they will qualify the conduit system fixtures.
The second item of concern is proper penetration protection for component enclosures. This concern is due to a difference in tested box connectors and installed box connectors on the Rosemount 1153 transmitters.
3.0 CONCLUSION
S The re-audit shows a considerable improvement from the July 13-17, 1981 audit findings.
It is concluded that, on completion of the commitments made by DECO concerning their Environmental Qualification Program, the program is adequate and in accordance with NUREG-0588.

APPENDIX B StM4 ARIES OF CENTRAL FILE REVIEWS Item:,Raychem Flentrol Cable PIS #2R340000400 This cable is used in the containment as part of the Plant Electrical o
System for emergency power.
The specified h 56.2 psig,1.98 x 10grsh environment for the cable is 340*F,100% RH, m
Rads total integrated dose, and demineralized water spray. The required operability under the harsh environment is 100 days.
The documentation file includes a draft " Interim Report of Flamtrol Thermal Aging Study," Raychem Lab Report 5058, dated February 1976, and
" Tests of Raychem Thermofit Insulation Systems Under Simultaneous Exposure to Heat, Gamma Radiaion, Steam and Chemical Spray While Electrically Ener-gized," FRC report F-C4033-3, dated January 1975, and prepared for Raychem by the Franklin Institute Research Laboratories. While the latter report is written to primarily address the splices, the cable is identified and discussed.
( Another report in this series, F-C4033-1, was written for the cables.)
The test parameters are 357'F and 70 psig with :8 steam atmosphere, chemical spray, and a total integrated dose of 2 x 10 Rads. Operability was demonstrated for 30 days and was extended by Arrhenius methodology to 100 days. A qualified life of 33 years was established by a 150*C, 168 hour0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> aging test extended by Arrhenius method.
A comparison of the above data shows acceptable testing with the exception of radiation. The applicant had identified this as a deficiency and intends to perform testing to be completed by July 1,1982. The reviewer agrees with the applicant's assessment of qualification status.
Item:
Rockbestos Firewall III Single Conductor Cable PIS #2R3400000000501 I
This cable is used in the containment for circuit continuity of Class lE circuits in the Plant Electrical System.
The specified harsh environment for the cable is 340*F,100% RH, 56 2 psig, demineralized water spray, and a total integrated dose of 1.98 x l
100 Rads. The required operability time under the harsh environment is 100 days.
s l
The documentation file includes two test reports, " Qualification ?f 3
Firewall III Class 1E Electrical Cables," dated July 7,1977 and having no report number, and " Qualification of Firewall III Class lE Electrical Cables (Irraaiation Cross-Linked Insulation)," dated May 1,1981, Rockbestos report l
number QR 1806. These test reports only differ in the amount of post-LOCA operability demonstrated, either of which is satisfactory for this applica-tion. The demonstrated test parameters are 346*F,113 psig,100% RH, 21 i
chemical spray, and irradiation of 2 x 108 Rads. Operability was shown for 365 days.
A comparison of the above data shows acceptable testing with the exceptions of only 6*F temperature margin and insufficient radiation. The applicant intends to perform testing for radiation to be completed by July 1,1982. The applicant has also shown that the temperature profiles have considerable margin and that both the required profiles and the test e'
profiles maintain higher-than-calculated temperatures for longer times.
The reviewer agrees with the applicant's assessment of this equipment.
Item:
Weihuller SAK (Melamine) Terminal Blocks PIS #2R340000901002 These terminal blocks are used in the reactor building as part of the Plant Electrical System for emergency power.
The specified harsh environment for the terminal blocks is I (LOCA),137*F (HELB),15% RH (LOCA),100% RH (HELB), and 5.4 x 10g0*F Rads total integrated dose. The required operability under the harsh environ-ment is 100 days.
The documentation includes a Franklin Research Center test report, F-C4959, " Qualification Test Program for Terminal Blocks," dated October 1978. This report shows test paramgters of 266*F, greater than 90%
RH, and a total integrated dose of 2.2 x 100 Rads.
By Arrhenius analysis the qualified life is 30 years and DBA operability is 100 days.
The test was a 168-hour test, designed as an aging test to achieve a qualified life of 40 years. The use of this test for both qualified life and DBA determination creates requirements for justification of methods in sequence selection, ramp time, and DBA monitoring.
DBA testing prior to irradiation is acceptable due to the minor severity of the DBA environment when compared to the 79*F and 71% RH that are the normals. The ramp time is inconsequential because the tested components were directly exposed to the test environment while the terminal blocks in the plant are enclosed and the enclosure internal temperature will lag the atmospheric temperature.
The terminal blocks are of simple construction and continuous monitoring of the electrical characteristics is not critical to this application.
The reviewer agrees with the applicant's assessment of this equipment.

RH, 56.2 psig,1.98 x 10 Rads total integrated dose, and demineralized water spray. The required operability time under the harsh environment is 100 days.
The documentation file includes a Franklin Research Center Test Report, " Qualification Test Program for Terminal Blocks," F-C5205-3, dated 22
October 1979. This report shows test parameters of 492 F,113 psig, a 8
steam environment, chemical spray, and a total integrated dose of 2 x 10 Rads. By Arrhenius analysis the qualified life is 39.4 years and the DBA operability demonstrated is 100 days. Qualification is dependent on pro-tection from direct spray. Aging is based on 294*F for 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br />.
A com'parison of the above data shows acceptable testing with the exception of radiation. The applicant has identified this as a deficiency J
and intends to perform testing to be completed by July 1,1982. It should be noted that, while there was no apparent degradation of the electrical characteristics, blocks did occur.af ter the above irradiation from Cobalt-60 gamma, warping of the terminal The applicant is aware of this and will carefully monitor the terminal blocks during the additional testing.
The reviewer agrees with the applicant's assessment of qualification status.
Item: ASCO Solenoid Valve (Model #NP8320A177E)
This unik is a pilot valve for air operated containment isolation valves in the Reactor Water Cleanup System outside the drywell. The harshest specified DBE environment for this location (zone 18) is 137*F and 6
100% R.H. at 0 psig with a total integrated radiation dose of 5.4 x 10 Rad. The required operability time is one minute.
The referenced file (EF2-052) included a Qualification Summary Report (QSR), Qualification Evaluation Report (QER), an Isomedix Test Report
(#AQS21678/TR Rev. A), vendor correspondence, and the Arrhenius Analyses to extend qualified life and to normalize the tested to the required (FSAR)
DBE profile.
In addition, three questions were asked during the audit.
Two of these were with regard to the tested valves being " identical to" or "similar to" the units to be installed. The QER and QSR indicate the valves are identical. The test reports show only that they are similar.
The differences are in coil voltage, body material, and solenoid enclosure type. The organic materials used are the same in all cases and the installed solenoid enclosures are of a higher standard than were those tested. DEC0 has agreed to revise the QER and QSR to say the installed units are only similar to the tested units.
The third question was with regard to the derivation of the activation energy, e, to be used in the analyses.
In tne analysis e was derived from the 10*C rule. This was shown to be conservative in this case, and was, therefore, accepted.
It should be noted that DEC0 has agreed to j
include the questions asked during the audit and the answers given as part of the central files. However, the affected analyses should be redone to reflect the proper e and the source of the value used. The documentation presented plus the answers for the questions asked supported the applicant's g
statement of qualification of this item in the environment specified.
Item: ASCO Solenoid Valve (Model #NP832094E)
This unit is a pilot valve for air operated containment isolation valves in the Reactor Water Recirculation System inside the drywell 23 s
(zone 22). The most severe environment postulated for this location is a LOCA with extremes of 340*F, demineralized water spray,100% R.H, and 0 ads 56.2 psig with a required integrated radiation dose of 1.98 x 10 R
(Beta + Gamma), 1.49 x 108 Rads (Gamma). The operability time required is six hours.
The referenced file (EF2-052) is the same as that which was reviewed for the ASCO NP8320A177E valve. Therefore, the discussion of the files t'
presented herein for that unit also applies to this valve.
The reviewers agree with the conclusions drawn by the applicant; i.e.
the valve is not qualified for use in the drywell due the required radiation levels.
Item:
Okonite Cable (Type:
Okonite Okolon)
This cable type is used in the Plant Electrical System in motor con-trol centers and distribution cabinets and in the drywell. The DBE environment specified for zone 19 outside the drywell is 137'F ang Rad.
100%
R.H. at 0 psig with a total integrated radiation dose of 5.4 x 10 The LOCA environment for inside the drywell (zone 22) is 340*F, demineral-ized water spray,9100% R.H. at 56.2 psig and a togal integrated radiation Rads (Beta + Gamma), 1.49 x 10 Rads (Gamma). The dose of 1.98 x 10 operability time required for this cable in both locations is 100 days.
The referenced file (EF2-082) contained a QSR, QER, a complete Okonite test report (unnumbered), vendor communication records and Arrhenius Analyses to extend qualified life and to normalize the tested to the required (FSAR) DBE profile.
During the audit of this file two questions were asked and two comments were made. All questions and comments were answered and the answers will be included in the DECO central files. The questions were in regard to the meaning of the terms "0kolon" and "0k o pren e. " DEC0 state that "0kolon" is a unique identifier for chloro-sulfonated polyethylene cable jackets, whereas "0koprene" is the trade name for neoprene jackets. The comments were in regard to the incorrect trans-fer of information between the test report, the QER, and the summary sheets.
DEC0 stated that the errors will be corrected.
We agree with the conclusions drawn by the applicant. That is:
a)
The Okonite Okolon cable is qualified for use in zone 19 outside the drywell, and b)
The Okonite 0kolon cable is not qualified for use inside the O
drywell due to the required radiation levels.

The file reviewed (EF2-085) included a QSR, QER, Test Report (#F-C 4497-2), vendor correspondence, and the Arrhenius Analyses to extend quali-fied life and to normalize the tested to the required (FSAR) DBE profiles.
The file stated that " Flame-Resistant Vulkene" was not comercially sold and that the correct name is "Non-Chlorinated Flame-Resistant Vulkene" (NCFR).. DECO was asked to verify that the installed cable was actually NCFR Vulkene, because this name was not used for the equipment summary sh eets. DECO answered that neither of the two types of cable has been purchased for Fermi 2.
It was included in the submittal because author-ization to use this cable has been given. When, and if, such cable is purchased, DEC0 will obtain the correct name and update the files and summary sheets accordingly. The documentation presented plus the answers to the questions asked during the audit support the applicant's position that this cable is not qualified for use in the drywell due to the radiation levels required.
