With respect to Reference Q 7 FRC notes that the information base is not easily ascertained. Reference Ny4dMCAP-7410-L, Vol. I of II, Section 4) describes environmental testing programs performed on process instrumentation. such as pressure and differential pressure transmitters manufactured ~ by ITT-Barton, Fischer & Porter, and ,Foxboro. FIRL Reports F-C2639 and F-C2667 are cited by M.m/fL-T A *.u**as evidence of qualification
" ~
for pressure and temperature steaA environmental accident conditions. FIRL Report F-C2639 describes results of three tests conducted on various Foxboro and Fisher & Porter transmitters. Teoc' No. 1 was conducted using four pressure transmitters as test ~ specimens, Test No. 2 was conducted using four differential pressWe transmitters, a7d Test No. 3 was conducted using two specimens previously tested in Test No. 2 plus two new pressure transmitters. A Foxboro differential pressure transmitter, Serial No. 2013081, was used as a test specimen in Test No. 2. Due to difficulty in maintaining a constant inout dif ferential cressure, this transmitter was retested in Test No. 3. F-C2639 did not specifically state the test temperature / pressure profile utilired in Test No. 3; however, the report implied that the same generic erivironmental profile was reasonably duplicated in all three tests. Following the environmental tests, Foxboro unit Serial No. 2013081 was seismically tested and subsequently radiation tested. , WithrespecttoReference43[,FRCnotesthats The referenced test stated that a Foxboro differential pres'sure
- - - transmitter, Serial No. 2013081, was used as a test specimen.

The Licensee suted tnac the total integrated radiation level af ter a DBE is 160 Mrd. FRC precumes that the difference between 160-Mrd and 20-Mrd values is in part due to beta radiation contribution. The referenced test stated that the Foxbore tran siAter, Serial No. 2013081, became inoperative during the _f icit/ Jhours of the irradiation test at an intecrated dose ofJ 'MYd."

i . i NOTES: . failure. If the cause of failure could not be corrected, Westinghouse suggested shielding the units, which are required to operate long-term post-accident, so that total dosage would be less than 1 Mrd. FRC concludes that beta radiation doses are not significant for qualification of this equipment. In addition, FRC concludes that sufficient evidence of test specimen transmitter's performance (accuracy and stability), prior to l failure during the test, does not exist to yarrjnt a determination of satis. factory operation up to a level of Mrd. Therefore, thetransmitterqualificationtotheanticEpateoradiation environment is deficient due to evidence of failure during the type test. The Guidelines require that equipment exposed to chemical sprays must be qualified for the.most severe chemical environment by either test or analysis. In addition, the effects of enclosure pressure boundary integrity and fluid in-leakage must be considered. As discussed previously, these transmitters could become submerged in the chemical solution. The test program ()
. has not addressed the potential for chemical attack on .
elastomer seals and gaskets, cocumentation () i providing evidence (in the form et .. .ter testing or analysis) , that the performance of this equipment is not degraded due to ""T" l containment spray solution should oe provl.ded. # a The Guidelines require that equipment operational modes during. testing should be representative of the actual plant application requirements. In addition, failure criteria should include instrument accuracy requirements. Tha referenced test stated that the maximum error of the Serial No. 2013081 transmit _ter's output signal during LOCA environmental testing was
~'
fin 0 to 10 seconds andl lfor the total test duration.'~ FRC concludes that'th'.a .s presumably unacceptable and reflects failure of the transmitter to perform with adequate stability. Unless the Licensee provides justification for acceptability of this maximum error range, FRC concludes that the unit has failed to qualify under environmental testing.

, EQUIPMENT ENVIRONMENTAL QUALIFICATION REVIEW OF EQUIPMENT ITEM NO. ./_d NOTES: ,
The Guidelines require that the test chamber temperature / pressure profile envelop the service conditions for a time equivalent to the period from the initiation of the accident until the service conditions return to normal values. As stated in the referenced test report', the test chamber time-dependent temperature / pressure crofile exceeded the postulated accident profile for ?
]but did not totally envelop the required eftvironmental serv cj renditions. The referenced test time duration, stated to be minutes, did not envelop the required accident profile
- 8. -hcir interval. The required environmental service conditions m such that the temperautre ceturns to normal (125'F) and the calculated worst-case presrure returns to normal (o psig) in 8.3 hours after the. initiation of the accident.
The Guidelines require that radiation exposure should be applied during the test sequence concurrent with or prior to the temperature and pressure / steam environment if it is known that the device contains materials which can be degraded by irradiation. FRC notes that the unit was seismically tested and subsecuently irradiated af ter the temeerature and pressure / steam environmental testing. It has been established that the _ transmitter is susceptible to radiation exposure as a result of testi'ng. In light of this, FRC concludes that the test sequence for this device should have included irradiation exposure prior to or concurrent with the temperature / pressure testing. _ i l l t 1

Pa. 19103 (21N 4481000 FRC Task No. to c / Tc'7 EQUIPMENT ENVIRONMENTAL QUAUFICATION REVIEW OF EQUIPMENT ITEM NO. 32.. LICENSEE RESPONSE The Reactor Coolant System loop RTDs were only tested to Rads R.
- gamma and were not thermally aged during qualification testing. The
' above radiation dose allows over 10 years of normal one.ation followed by one week of post-LOCA containment radiation. This would be sufficient time after a postulated accident to place the plant in a stante condi-tion such that the RTDs would not be required. In addition, back-up indication such as steam generator saturation pressure or Residual Heat Removal systes temperature are available depending on the mode of alant cooling. Therefore, continued safe operation of the plant is assured.
It is our intention to continue evaluation of the present RTDs for thermal aging and a higher radiation dose in order to fully qualify these RTDs to the DDR Guidelines. High normal ambient temperatures and hign normal radiation dose rates make the environmental qualification of these cong'onents extremely difficult. It is our intention to replace them with fully qualified RTDs by the. environmental qualification deadline, if possible. . G e F l E __

The temperature profiles for the specification and the qualification test are essentially equal. The specification temperature was computed using extremely conservative assumptions. The highest possible superheat temperature from a steam leak at the highest secondary p* essure was I
- calculated for the peak temperature. This also assumed no cooling by

the internal tasperatures of the equipment being tasted (e.g., valve i l entor operators) reached higher levels during qualification testing than that which could result from a short-duration steam ifne break accident. Electrical cables are run in conduits near high energy ifnes so that direct steam impingement on cables is impossible. Therefore, the temperature profile of the test is considered adequata to qualify the equipment to the specification tasperature profile. l i V. The Limitorque Model SM8 valve motor operators inside containment (or near a high energy line outside containment) have either Rolf ance or Peerless motors with Class 8 insulation. Generic environmental tests on these operators are documented in Westinghouse WCAP-7410L and Limitorque Test Report No. 80"03 (Qualification References 18 and 168, respectively). The tests included thermal aging to the equivalent of greater than 40 years at an annient tamperature of 40*C (104'F) assuming the "10*C Rule." All safety-related valve operators inside containment are located outside the primarf shield walls where the ascient tamcer-atures during operation are maintained by design at less than 105"F and by experience at less than 100*F. Safety-related valve operators in the aumf11ary building outside containment have ascient tamperatures

In addition, the tests documented by Test Report 80003 demonstrata that the units can survive a saturated staan environment at 10 psig for at least 16 days. This - demonstratas their qualification for operation in 1005 relative humidity , and steam for long periods of time. The valve operators wev1d therefore be considered qualified for an operating time of 24 hours following a design basis accident except as limited by the radiation qualification of the operator. The qualified level of radiation integrated dose postulated for the PSNP containment reach 2 x 107Rads at approximately 12 hours following a design-easts accident. Therefore, these valve operators are considered qualified for a maximum operating time of 12 hours in a LOCA or HELB environment inside containment.

Peerless motors with Class 8 insulation. Generic environmental tests on these operators are documented in Westinghouse WCAP-7410L and ' Limitorque Test Report No. 80003 (Qualification References 18 and 168, respectively). The tests included thermal aging to the equivalent of greater than 40 years at an ancient temperature of 40*C (104*F) assuming the "10*C Rule." All safety-related valve operators inside containment are located outside the primary shiel'd walls where the ambient temoer-atures during operation are maintained by design at less than 10$'F and by experience at less than 100*F. Safety-related valve operators in the auxiliary building outside containment have ambient temperatures-which are maintained between 65 and 85'F. The qualification tests also l ' included mechanical and vibration aging. The potential for unexoected degradation due to aging is addressed by periodic insoections, electrical tests, and mechanical tests. Periodic maintenance keeps these valve operators in an "as now" condition over their 40 year qualified Iffe. See Wisconsin E'.actric's September 11, 1981 letter to Mr. Harold R.
