Clark, Chief Operating Reactors Branch 3 Gentlemen: DOCKET NOS. 50-266 AND 50-301 PROPRIETARY INFORMATION IN TECHNICAL EVALUATION REPORTS ON ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 Mr. Clark's letter dated December 22, 1982 forwarded a Safety Evaluation Report (SER) and a Technical Evaluation Report (TER) prepared by the Franklin Research Center concerning the environmental qualification of safety-related electrical equipment for each unit at the Point Beach Nuclear Plant. Portions of the information supplied in the TER's included test reports and other documents which contained information which had previously been accorded proprietary protection. Wisconsin Electric was requested to contact the owners or originators of this information and clearly identify which information still required proprietary protection and provide the specific rationale and justification for this protection. As discussed in our letter to you dated January 26, 1983, we provided the TER's to the Westinghouse Electric Corporation, the owner of the information, and requested that they complete a review of this information and clearly identify the proprietary details. Westinghouse has completed this task. For your convenience we have attached a listing, by Equipment Item Number and page, of those sheets from the TER's which still contain proprietary information. Please note that except for item numbers 69 and 70, those equipment item' numbers listed apply to the TER's for both Point Beach Nuclear Plant, Units 1 and 2.

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                                     .

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

Unless the Licensee provides justification for acceptability of this maximum error range, FRC concludes that the unit has failed to qualify under environmental testing.

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

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 __

A failure                           is per=1cted if it is random, i.e., not indicative of co==on mode failure.

No rationale was provided for the 2-out of-3 acceptance criteria or technical bases for determining when a failure is not common mode. See related Note (, Note 6 WCAP - 9157 reports accuracy require =ents of t 5%. Testing performed did not provide information on worse case error under design basis accident conditions. Also, the qualification program did not address the ability of the RTDs' time response with respect to primary loop temperature changes and trip points under SL3 conditions. It appears this information is an important consideration for this device. Rosemount - specifications on DWG 176KF (Rev E ) states: q l [ l 1 1 l- -

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

Periodic maintanance keeps these valve operators in an "as now" condition over their 40 year qualified life. i See Wisconsin Electric's Septanner u,1981 letter to Mr. Harold R.

The pH Ts at the bottom of the pH range specified. The short required operating time of the units (maximum of 14 hours and usually - l only 30 minutas) would not allow a slightly higher pH solution to l significantly increase the chemical corrosion of the units over that solution which was used in the test. The boric acid concentration was much higher in the test than that required for PSNP. The specified tamperature and pressure profiles were both enveloped by the tast profit operators were tastad successfully periodically through-out th urs of testing. The ra were exposed to saturated steam a sig for an additional after which they failed to operate p erly. The cause of failu was analyzed and datarsined to be the entry of chemical spray into the unit through the motor lead cutouts. The motor lead cutouts are sealed at PSNP with flexible conduit and associated fittings. Although these fittings have not been qualified, their design indicatas that no significant amounts of chemical spray could entar the units via this path. 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. In conclusion, these Limitorque valve operators are considered qualified for LOCA or HEL8 envir9nments inside containment, 100% relative humidity, i chemical spray, 2 x it.

i EQUIPMENT ENVIRONMENTAL QUALIFICATION REVIEW OF EQUIPMENT ITEM NO. fc.3 1 i LICENSEE RESPONSE TO NRC SER l V. The 1.f attorque Model SM8 valve motor operators inside containment (or near a high ensrgy line outside containment) have either Reliance or Peerless motors with Class S insulation. Generic environmental tests " on these operators are documented in Westinghouse WCAP-7410L and Limitorque Test Report No. 80003 (Qua'ification References 13 and 158, respectively). The tasts included thermal aging to the equivalent of greatar than 40 years at an ameient temperature of 40'C (104'F) assuming j the "10'C Rule." All safety-related valve operators inside containment are located outside the primary snield walls where the ambient temper-atures during operatic. are maintained by design at less than 105'F and by experience at less than 100'F. Safety-relatad valve operators in the auxiliary building outside containment have amoient temperatures ! which are maintained between 65 and 85'F. The qualification tasts also ! included mechanical and vibration aging. The potantial for unexceeted degradation due to aging is addressed by periodic inspections, electrical tests, and mechanicai tasts. Periodic maintenance keeps these valve operators in an 'as new" condition over their 40 year qualified life. see Wisconsin Electric's September 11, 1981 letter t-c Hr. Harold R. Denton concerning reponse to the environmental qualification SER (specifically Enclosure 1, Section 3.7) fpr a further discussion of .ging. The tests documented by WCAP-7410L included i atfer! of both Reliance and Peerless motors with Class 8 insulation to Rads gama. The tasts documented by Test Report No. 80003 inclu ed fr Mdiation3 af Reliance motors with Class 8 insulation to greater than 2 x 10 Rads i gasuna and irradiation of the operators including the geareg limit switches, torque switches, seals, and lucricants to 2 x 10 . Rads gamma. The operators were successfu1%f,astad for 1.0CA conditions inside containment for a duration of JhoursasdocumentedinWCAP-7410L. The test included chemical sp Yay with a 1.5 weignt precent solution of F l boric acid (H S0,) buffered to a pH of 7.85 with sodium hydroxide c j (NaOH). The hH Ts at the bottom of the pH range specified. The short ! required f.,cerating time of the units (maximum of 14 hours and usually . c only 30 minutas) would not allow a sligntly higher pH solution to e significantly increase the chemical corrosion of the units over that 5 solution which was used in the test. The boric acid concentration was 5 much higher in the tast than that required for PBNP. The specified & tamperature and pressure profiles were both enveloped by the test j profiles e operators were tastad successfully periccically through-out th ours of testing. The ators were exposed to saturated staan a psig for an additional days after wnich they failed to ,, operata properly. The cause of 11ure was analyzed and datarnined i to be the entry of chemical spray into the unit through the motor lead n-cutouts. The motor lead cutouts are sealed at PBNP with flexible I conduit and associated fittings. Although these fittings have not been g qualified, their design indicatas that no significant amounts of chemical 2 spray could entar the units via this path. In addition, the tests p documented by Test Report B0003 demonstrata that the units can survive c: a saturated staam environment at 10 psig for at least 15 days. This * - demonstratas their qualification for operation in 100% relative humidity and steam for long periods of time. The valve o tors would therefore be considered qualified for an operating time of hours following a design basis accident except as limited by the rad tion cualification 3 of the operator.

The operators were successfully fastad for LOCA conditions inside containment for a duration afg , hours (documented in VCAP-7410L) and for MELS conditions outside cont:inment for a duration of 16 days (documented by Test Report 80003). The qualification of these valve l operators for 10C". relative humidity is demonstrated b 9e successful tests in saturated staa:s at elevated tamperatures fo ours in one test and 16 hours in another test. . l Therefore, these Limitorque valve operators fre considered generically l qualified for 10C". relative humidity, 2 x 10 Rads ga=ma radiation, ane a 40 year lif etime. $1nce these valve operators have succassfully operated for years in their normal environment and since elevated tamperatures and high humidity are not expected in the auxiliary building where these operators are located, the operators are judged to be qualified for a sinimum operating time of one year.

The t.f aitorque Mcdel SM8 valve actor operators outside containment at Point Beach Nuclear Plant have either Reliance or Peerless motors with Class 8 insulation. Generic environmental tests on t.*ese operators are documented in Westinghouse WCAP-7410L and Limitorque Test Report No. 80003 (Qualification References IS and 168, respectively).

The tests included ther nal aging to the equivalent of greater than 40 years st an amotent tamperature of 40*C (104*F) assuming the "10*C Rule." The tests also included mechanical and vibration aging. The potential for unexceeted degradation due to aging is addressed by periodic inspecuens, electrical tests, and mechanical tests. Periodic saintenance keeps these valve operators in an "as new" condition over their 40 year qualified life. See Wisconsin Electric's Septammer 11, 1981 letter to Mr. Harold R. Denton concerning response to the PENP environ-mental qualification SER (specifically Enclosure 1, Section 3.7) for a further discussion of aging.

                                                               ~

The tasts documentad by WCAP-74101 included i att of both Reliance and Peer 1 css motors with Class B insulation to . Rads gamma. The tests documented by Report No. 80003 included adia on of Reliance cotors with Class B insulation to greater than 2 x 10 Rads gamma and irradiation of the operators including gepred limit switenes, torque switches, seals, and lunricants to 2 x 10 Rads gamma. ! The operators were successful) estad for LOCA conditions inside containment for a duration of ours (documented in WCAP-7410L) and for HELS conditiens outside cLm in=ent for a duration of 15 days (documented by Test Report S0003). The qualification of these valve e successful operators for 10C". tests in saturated staamrelative f.umidity at elevatad is demonstrated tamperatures for{ my f"n: curs in one tast and 16 hours in another tast. Therefore, these Limitorque valve acerators fre considered generically qualifisd for 10C'. relative humidity, 2 x 10 Rads gamma radiation, and' a 40 year lifetime. Since these valve operators have suecassfully operated for years in their normal environment and since elevatad temperatures and hign humidity are not expected in the auxiliary building where these operators are located, the operators'are judged to te qualified for a minimum operating time of one year. s I

The tasts included thermal aging to the ecuf valent of greater than 40 years at an amoient temperature of 40*C (104*F) assuming the "10*C Rule." The tests also included mechanical and vibration aging. The potantial for unexeected degradation due to aging is addressed by periccic inspections, electrical tests, and mechanical tests. Periodic saintenance keeps these valve operators in an "as new" condition over their 40 year qualified life. See Wisconsin Electric's Septescer 11, 1981 lettar to Mr. Harold R. Canton concerning response to the PENP environ-mental qualification SER (specifically Ecclosure 1, Section 3.7) for a further discussion of aging.
