SUBJECT:
TRIP REPORT - AUDIT OF DETROIT EDISON'S DOCUMENTATION FOR ENVIRONMENTAL QUALIFICATION OF CLASS 1E ELECTRICAL EQUIPMENT PER NUREG-0588 FOR ENRICO FERMI ATOMIC POWER PLANT, UNIT 2 Plant Name:
Enrico Fermi Atomic Power Plant, Unic 2 Docket No:
50-341 Licensing Stage:
OL Responsible Branch: Licensing Branch #1 Project Manager:
L. Kintner Review Status:
Continuing During the week of December 14-18, 1981, a team consisting of NRC staff and consultants f rom EG&G Idaho audited the Caroit Edison central document files containing environmental qualification information for safety related electrical equipment in the Fermi 2 plant.
The purpose was to determine if tangible evi-dence was available in the files to demonstrate that equipment will function as required during and after a design basis accident.
In addition to the central file review, several general areas of the environmental qualification program were reviewed as discussed below and additional information received from the applicant.
A list of the participants is provided in Attachment 1.
The environmental qualification program for fermi 2 was submitted by letter dated December 1, 1981.
A prior audit based on a July 1,1981 submittal is described in a trip report dated October 10, 1981.
In the latest revision, the appiicant identified five equipment items as being environmentally qualified (two of these in selected areas of the plant only) from a total of 150 equipment types.
Eight items had specific qualification deficiencies and corrective action plans for these deficiencies identified.
The balance of the equipment is scheduled for replacement or NUREG-0588 Category I qualification testing.
The audit team reviewed the central document files for eleven equipment items and agreed with the applicant's conclusions regarding qualification or quali-fication deficiencies in all cases.
The files were organized into sections 8202100056 820127 PDR ADOCK 05000341

containing summary information, vendor documents, analysis, and test reports.
A portion of their December 1, 1981 submittal contained a complete summary of i
all equipment types, including plant identification numbers, qualification status, and specific corrective action plans with a schedule for completion.
The items audited were also 'xamined in the plant for model identification, mounting, and electrical intc. faces and a discussion of the results can be found in Attachment 3.
j Generic items relating to the overall program for environmental qualification i
of electrical equipment were discussed during the audit and a summary of the J
information provided is given below:
i The master list of systems needed to perform class IE functions was expanded from those only in a harsh environment to all systems, including l
those in a mild environment.
The applicant also provided a listing of the l
class IE functions performed by each of the systems on the master list.
i
?
The status of the TMI action plan items was presented by the applicant.
All installed TMI equipment was included in the December 1, 1981 submittal.
The applicant provided a summary of the possible flooding in the drywell and a list of the equipment located below the flood level.
The only safety-related equipment below the flood level are cables enclosed in conduit.
Although the cables have short term qualification testing, long i
term submergence testing has not been performed on all types of cables.
Since there are several pull boxes and fittings which could permit water to enter the conduit, submergence qualification is necessary.
The appli-cant agreed to obtain documentation to support submergence qualification of the conduit fittings and pull boxes.
It was noted during the walkdown that the design of the pull boxes may not permit a demonstration of leak-tight integrity.
llence, replacement or modification could be necessary.
Enclosure of the cable in watertight conduit would demonstrate qualifica-l tion of the cable for its postulated environment.
l for several items not fully qualified, the applicant proposed partial I
testing to supplement existing radiation test data.
The procedure described by the applicant for qualifying equipment to radiation doses higher than in the original c,ualification test involves measuring equip-ment degradation at the original dose and comparing this degradation with i
that caused by the larger dose needed for full qualification.
The audit team agreed that a properly conducted test could be adequate for achieving full qualification if the proper measurements of degradation were performed and the increased degradation, if any, from the original test level were insignificant.
The applicant agreed that full Category I testing would be performed if si nificant degradation were to result from the incremental 0
radiation doses.
The applicant described the outline of a maintenance / surveillance program which is currently being developed.
A computer program will be utilized i
i
-.-...-,.-~. - -.
s Z. R. Rosztoczy 3

J to identify periodic maintenance / surveillance activities to assure that equipment will.not' degrade faster than anticipated.
In addition to incorporating manufacturer's recommendations for replacement of components or maintenance procedures, it will utilize the results of operating experience, performance testing, and trend analyses.
This program is i
expected to be implemented in 1982.
As a result of the plant walkdown, the applicant should confirm that all electrical interfaces in a harsh environment have been included in the environmental qualification program.
It was noted in the exit interview that since a large portion of the equipment would be undergoing qualification testing or replacement, a follow-up inspection could be conducted in the next year or two.
It was determined by the audit team that the overall status of the environmental qualification program is satisfactory.
The equipment to be qualified is identified, the environments are known, the documentation requirements are understood, and some equipment is fully qualified.
In addition, a plan for achieving full qualification of all equipment has been developed and is being implemented.

Rosemount 1153GB7 Pressure Transmitter (PIS No. 282106N490)
This pressure transmitter is used to monitor the main steam line pressure during the post LOCA period.
It provides an indication to the control room and is 1:
also interlocked with two isolation valves of the MSIV Leakage Control System.
'During normal operation, these valves are closed.
Approximately 20 minutes following a LOCA, the MSIV Leakage Control System can be manually initiated by the operator.
Should the main steam line pressure drop below 50 psig,_the transmitter will provide a permissive signal to open up these two valves allowing control air to pressurize the pipe boundary between the main steam isolation valves.
i The transmitter is located in the reactor building and during a LOCA is exposed to an environment consisting of a peak temperature of 130 F, and a radiation i
dose of 5.4 x 106 Rads.
These parameters envelope the high energy line break conditions with the exception of relative humidity, which is 100% for the line break.
The qualification documentation consisted of Rosemount reports 108025 Rev. none j
and 108026 Rev. none.
In these reports, various 1153 model transmitters were subjected to IEEE 323-1974 testing with a peak temperature of 318 F and a peak pressure of 73 psig for an eight hour period.
The radiation dose prior to LOCA testing was 2.4 x 107 Rads gamma.
Thermal aging was performed before and after i
LOCA testing to simulate normal operation and post accident conditions.
Arrhenius calculations were performed with these thermal aging data to obtain a qualified life of 27.8 years, including margin.
Various other aging tests (pressure cycling, power on/off, vibration and storage) were also performed prior to LOCA t esting.
The applicant should also consider the results of operating experience in determining the final qualified life.
The reviewer agrees with the applicant's conclusion that the equipment is qualified for the environment specified.

ECCS Pump Motor, General Electric, Model 5K6348XC39A (PIS No. 2E1102C002A) i This motor is part of the residual heat removal system and provides power for I
the RHR pumps.
It is located at elevation 539 ft 6 inches in the western corner
'l room in the subbasement of the-reactor building.
During a LOCA it is subjected to harsh environmental parameters consisting of a 150 F temperature and a radia-tion dose of 5.4 x 106 Rads.
The bounding humidity condition, caused by a high i
energy line break, is 100% and the required operability time is 100 days.
The motor is subject to submergence but a redundant motor in a location not affected by flooding performs the required safety function.
i Several of _the test reports used_ for qualification are proprietary to the NSSS llence, the audit review of the central file relied upon the applicant's vendor.
i summary information from these test reports.
Test reports in the NSSS vendor's central file will be audited at a later date.

The applicant's central file referenced GE Test Report 456HA898 Rev. 8 to establish a 40 year qualified life and 08A operability of the motor insulation system with a margin of greater than 100% on operating time.
GE Test Report 491HA988 contains sequential test data on materials similar to those in the Fermi 2 motor. A similarity analysis was provided to demonstrate that the test data were applicable to Fermi.
The radiation exposure for the similar material was 5.5 x 100 Rads TIO.
Analysis and test data were used to show qualification of the motor's lead wires.
A qualified life of 40 years was demonstrated.
Data from sequential testing of motors similar to those at Fermi, excluding motor insulation, were presented in 6
GE Test Report 22A4722.
An extensive comparison and analysis of the tested motor construction versus the Fermi motor was provided.
Based on the summary iiformation supplied, the motor is qualified to NUREG-0588 Category II for the environment specified.

Weidmuller SAK (Melamine) Terminal Blocks (PI5 #2R340000901002)
These terminal blocks are used in the reactor building as part of the Plant Electrical System for emergency power.
The specified environment for the terminal blocks is 130 F (LOCA),137 F (HELB), 15% RH (LOCA), 100% RH (HELB), and 5.4 x 106 Rads total integrated dose.
The required operability under the harsh environment 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 parameters of 266*F, greater than 90% RH, and a total inte-grated dose of 2.2 x 108 Rads.
By Arrhenius analysis the qualified life is 30 years and DBA operability is 100 days.
The test was a 168-hour test, designed 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 in this application is acceptable because the tested componcats 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.
In addition, the LOCA ramp time is approximately one hour to reach 130 F.
The low temperatures of the postulated accidents, the short duration of the high humidity line break (12 seconds above 130 F), and low relative humidity of 15% for the LOCA were factors considered in the analysis of operability.
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.

Raychem Flamtrol Cable (PIS #2R340000400)
This cable is used in the containment as part of the Plant Electrical System i
for emergency power.
Fermi 2 2
The specified environment for the cable is 340 F, 100% RH, 56.2 psig, 1.98 x IOS 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 Radiation, Steam and Chemical Spray While Electrically Energized," 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 y
series, F-C4033-1, was written for the cables.)
The test parameters were 357*F and 70 psig with a steam atmosphere, chemical spray and a total integrated dose of 2 x 108 Rads.
Operability was demonstrated for 30 days and was extended by Arrhenius methodology to 100 days.
