ELECTRICAL PENETRATION Manufacturer, Model: Amphenol Type IA, IB, and IC, Spec. NUS-41 Tag No(s).: Worksheet No(s).: 6-43, 44, and 45 QDR No.: 5437;.. 59-01 Location: RC-18B DISCREPANCY The TER identifies concerns in the following areas: A. Similarity between equipment and test specimens B. Aging and qualified life C. Temperature/pressure test profile D. Spray E. Radiation RESPONSE The attached pages discuss these concerns in detail. It is concluded that all of these concerns are resolved except Aging and Qualified Life. As recommended in the QDR, the penetrations should be included in a surveillance program. The TER assigns other equipment of this sort to Category IIc. -

- ATTACHMENT TO SURRY 1 ITEM 8 AMPHENOL PENETRATIONS A. CONCERN: (1) Similarity Between Equipment and Test Specimens (page 2 of TER) . (2) It is not clear why _the manufacturer was not contacted to determine the applicability of the test reports. It is noted th.at.Amphenol has provided test documentation to other plants, i.~., Calvert Cliffs, Trojan, San Onofre, Davis Besse and ANO (page Sf of TER) RESOLUTION:

The Amphenol penetrations used at Surry are of the canister type, rather than the unitized header design supplied for *later plants such as Davis Besse and AN0-2. Copies of ten references are attached documenting tacts with Amphenol to obtain copies of suitable test reports for the canister design (which they could not pr-o,(1de) or for the uni ti zed header design (which were ultimately obtained directly from Toledo Edison and Arkansas Power & Light). Additionally, the referenced QDR contains tial documentation relating the canister and unitized header designs. In particular, the "Design Evolution" report included with the original Amphenol proposal in Section 2b of the QDR provides a detailed description of Amphenol's penetration design evolution from canister to unitized header. The photographs and drawings in this report, together with the drawings in the Proposal, clearly establish that at the time Surry p-enetra--f1ons were fabricated the-two "designs employed the the same connector modules, insulation materials, potting compounds, and sealants; only the structural metallic components in which these items are mounted and related welds differ. Amphenol's Design Verification Test Report, included in Section 3d of the QDR, summarizes the reasons for evolving from the canister to the unitized header design (page 1): "The unitized header assembly (UHA) offers the advantages of a lighter, more compact unit than the canisters which have been used heretofore and also vides for versatility and interchangeability of ents. In addition, the UHA promises to considerably reduce the required field installation effort." Sheet 10 of the QDR, reproduced on page Sf of the TER, documents additional comparisons performed by NUS to verify the similarity between Surry equipment and the test specimens used for the test reports employed by _the QDR .*

*-* Surmnarizing, the manufacturer was contacted edly to obtain applicable test reports. In the absence of complete test reports for the canister design used at Surry, design similarity to the tested unitized header penetrations was established using information pro-vided by the manufacturer. ,Test reports for the unitized header penetrations were obtained and used to establish the qualification of the Suiry penetrations.

This effort adequately determines similarity between the plant ment-and test specimens in conformance to tpe DOR Guide--B. CONCERN: (1) Aging Degradation Evaluation (page 2 of TER) (2) Qualified Life or Replacement Schedule Establishe~-(page 2 of TER) -(3) No aging evaluation has been conducted (page Sh of TER) RESOLUTION: Sheet 11 of the QDR, reproduced on page Si of the TER, summarizes the thermal cycle test in Amphenol report 123-1275 but does not provide an Arrhenius ~alculation to predict a qualified life. Clearly such a.calculation would predict a very long life: for example, using the conservative activation energy of 0.7 ev-developed on sheet 13 of the QDR, the one hour of thermal testing at 400°F corresponds to over 1,000 years at the compartment ambient of 105°F.

The QDR concluded that the evidence is not sufficient to justify a 40 year qualified life, and an Ongoing Aging
Surveillance Program should be performed.

This deficiency by itself would not cause the penetrations to be fied in TER Category IIa. Category IIc, "Qualified Life Deficiency," would be appropriate

*
C. CONCERN: (1) Temperature/Pressure Test Duration (TER page 2) (2) Temperature/Pressure Required Profile Enveloped by .Test Profile* (TER page 2) (3) Note 5 states that two referenced tests envelop neither the peak temperature nor entire tion, while a third referenced ti:=st which ceeds the peak temperature does .not have quate duration.* (TER page Sj; test and plant profiles reproduced on pages Sk *through Sn). RESOLUTION:

This concern primarily reflects the fact that in 1972 the industry did not conduct 120-day .LOCA tests; secondarily, the peak temperature in the Davis Besse LOCA test (the most closely related test to Surry .LOCA conditions) is slightly lower than for Surry~ This cern is not considered significant for the reasons that follow. The Surry peak LOCA temperature for the penetrations is 280°F for 30 minutes. It decays to 150°F in the next 30 minutes, then to 120°F by the end of two days and remains at 120°F for the balance of the 120 day post-LOCA required operating period; Attachment No. 2 of the QDR presents a series of Arrhenius calculations to show that the Davis Besse LOCA test is more severe than the Surry LOCA. This is shown by converting both profiles to equivalent time at 120°F, using a conservative actiation energy of 0.7 ev. The calculations show that the Davis Besse test corresponds to an additional two months of post-LOCA operation at Surry after the r*equired

120 day operating time. The two LOCA profiles, shown in Figure 13 of the QDR, do not differ significantly, and this approach is not considered to represent an abusive use of the Arrhenius technique.-

Since the Davis Besse test did not bound the Surry. peak temperature, the QDR also referred to Amphenol's "Maximum Credible Accident" test. In this test the penetrations experienced 300°F for 15 minutes dropping to 250°F for the balance of 24 hours. The thermal aging test discussed under the aging concern exposed the trations to seven hours at or above 300°F; this test was performed in dry air rather than steam. These two tests provide substantial evidence that threshold effects or other adverse behavior will*not occur in the small portion of the Surry LOCA peak not enveloped by the Davis Besse test .

With respect to the concern that Arrhenius lations should not be used to extrapolate ture, saturated.steam exposure to low temperature, rich operation, two points are noted: First, in Attachment No. 2 of the QDR it is evident that most of the "credit" for post~LOCA operating time derives from testing at or below 180°F, which does not reflect a steam environment.

Second, the aging just.if ies many years operation at bient temperature, based on the oxygen-rich thermal aging test. It is noted that the QDR contains.an error in seriting LOCA test results. For the Davis Besse test both temperat~re and duration values used are incorrect because the test procedure rather than the test report was used. The TER presents correct conditiohs.

In spite of the error the results of _the calculation in Attachment No. 2 of the QDR remain valid (lower temperature and longer time tend to offset), but the QDR will be corrected.

Summarizing, the justification for LOCA tion of the penetrations is considered valid. D. CONCERN: (1) Spray (page 2 of TER) (2) "Boric acid was mixed and boiled to make steam. No spray was used." (page. Sj of TER) RESOLUTION: The direct impingement forces of droplets from tainment spray nozzles become insignificant relative to LOCA pressures beyond one or two feet from the nozzle, The Surry penetrations are located no closer than several .feet from spray nozzles. Thus the spray test is sidered to have adequately simulated the Surry LOCA vironment even though the solution was not directly sprayed through a nozzle into the test chamber. E. CONCERN: RESPONSE: (1) (2) Radiation (TER page 2) Note 4 challenges the qualified radiation dose of 1.03xlo8 rads claimed in the QDR (TER page Si) The TER presents (on page Sh) documentation from the Hanford laboratory showing that, although portions of the test container received 1.03xlo8 R, other portions received as little as 1.22xlo7 R. The TER further sents on page Sh a caution that radiation exposure was quoted in Roentgens and would have to be converted to rads to reflect absorbed dose. The required radiation dose for the Surry penetrations is 7.44xlo6 rads (40 years plus LOCA). The conversion from Roentgens to rads for the organic materials of cern is unlikely to vary from 1.0 by more than ten to twenty. percent, so the qualified dose is at least lxlo7 rads. This exceeds the plant environment. r ..... -~, ., vc*rc --.

RESPONSE Cerro Wire and Cable Company correspondence** included in the referenced QDR, we.re re-reviewed and the applicability of the test reports to various cables is established in the attachment of this TER ITE No. 36. Per IEEE Paper dated May, 1969 "Insulation and Jacket~ for Control and Power Cables in Thermal Reactor ;Nuclear Generating Stations" the XLPE insulated are designated in radiation class 3 (8.8xloB Rads) and recommended for nuclear use for safety related equipment. This equipment should be classified in Category Ia, "Equipment Qualified" as was done for item 45 and 3S*in Surry Unit #1 *

ATTACHMENT TOTER ITEM NO. 36 OF VEPCO SURRY UNIT #1 Qualification of Cerro XLPE Cables Following is the surrunary on Cerro XLPE. cable qualification in regard to FRC evaluation:

1. lOOOV, XLPE Cables: (TER ITEM #36 for Unit #1 & 73 for Unit #2) lOOOV, XLPE cables were bought under the following 4-different specifications:

i) Specification No. NUS-325, (P. 0. #SN-246) , dated July 30,69. ii) Specification No. NUS-362, (P. 0. #SN-1246) ,dated Feb. 17,70. iii) Specification Nao Nus.:...381C, (P.O. #SN-446) , dated Jan. 22 J-71 March 22

iv) Specification No. NUS-381E, (P.O. #SN-1447/1246), dated April 131-June 10 _ 1971 All the above cables were covered in QDR-5437-55-01 for Unit No. 1 and 5437-134-01 for Unit Nao 2o Qualification is established as follows: i) Per Stone and Webster letter, dated Dec. 12, 1980, to Rockbestos (attached) and the purchase order,_ the cables -under . Spec. NUS-325, P.O. SN-246 were bought,from Dec. 15, 69 thru July, 23, 70 Spec. NUS-381C, P.O. SN-446 were bought from July 19, 1971 thru Aug. 23, 1971 Spec. NUS-381E, P.O. SN-1447 were bought from Aug. 18, 1971 thru Sept. 7, 1971 Spec. NUS-362, P.O. SN-1246 were bought from June 19, 1970. thru March 8, 1971 Therefore, all the above cables were shipped from Dec. 15, 1969 thru Sept. 1971. ii) Cerro letter dated Aug. 1, 1969 (included on page* 3b of the referenced QDR) indicates that all the lOOOV XLPE cables will be "Pyro Trol-IIIII control cables in accordance with the VEPCO specifications.

These were manufactured by Cerro Company per their Specification No. B,SS-_3::_70_1 o_:L_ll/l/6!L_(pa,qe_.3b of the of the QDR) with the exception of thickness. Thickness was in accordance with IPCEA Standard. The Specification No. RSS-3~701 indicates that the insulating compound used was flame-retardant, chemically cross-linked polyethylene.

*-* iii)Cerro Wire & Cable Comp. letter dated Aug. 20, 1969 (Page 20 of the referenced QDR) indicates that the cables manufactured were* "Pyro-T.rol III" cables* which were *tested by FRC Report No. F-C2404-0l, dated June 1969~ iv) Franklin Report No. F-C24-04-01 was prepared in June 1969. It included only radiation testing upto 2.5:x:107 rads, humidity testing of 6 hrs, and steam pressure test@ 62 psig for 15 min., and cooleddown to 150°F in 30 min. Four samples were tested from product code 644N30 and 655N30 -series (four diff. batches).

v) We procured one.more Franklin Report #F-C2857 dated Sept. 1970 in which they tested 8 different types of Cerro cable. They included one sample of ."Pyro-Trol III" cable also with the same product code 655N30 series (30

mils of flame retardant cross-linked polyethylene insulation thickness).

This report addressed radiation (from 55 Mrad thru 179 Mrad), humidity, steam press. & chemical spray test for 7 days. The spray test of seven days is quite severe to justify the LOCA requirement of the plant (see the *attached analysis). Our QDR will be revised to reflect the review of the subject cables per these reports and the Franklin Report #F-C3798 which is used to qualify .these cables will be deleted. 2. 300V & 600V, XLPE Cables: (QDRs-5437-50-01,51-0.l.,53~01.for ,Unit #1& QDRs:-5437-118-01,119-:-0l,121-0l--Unit

2 Originally these *30ov* & 600V, XLPi cables were bo~ght for N. Anna power plant but later were transferred to Surry. power plant for the required use. These were bought under the following 2 different cations: i) Specification No. NAS-120, (P.O. #NA-312/lj12), dated Oct. 196~ thru March, 1972. ii) Specification No. NAS-3187~(P.O.
NA-3187/4183), dated Oct. 11, 1973. iii)Specification No. NAS-430, (P.O. #NA-392/1392), dated June, 1974. Qualification of cables in Spec. NAS-120, NAS-3187, & NAS-430 is addressed in QDR #s. 5437-50-01,.

5437-51-01 & 5437-53-01 respectively for Unit #1 (QDR #5437-118-01, 5437-119-01, 5437-121-01 for Unit #2) .

Qualification is established as follows: i) Per-Stone.

& Webster letter, dated Dec. 12, 1980, to Rockbestos and the purchase orders the cables were

supplied during the following period: Cables under Spec. NAs,.,.120; P.O. NA.:...312/1312

-June 23, 1972 thru March, 1978. Cables under Spec. NAS.:...3187, P.O. NA-3187/4187 -May 21, 1976 thru Nov. 1976. Cables under Spec. NAS-430,. P.O. NA.:..:392/1392 -June 24, 197 4 thru Aug. *197 8. ii) Rockbestos Comp. wrote a letter to S&W on Feb. 21, 1979 which indicates that the cross-linked polyethylene cables supplied under P.O. NA.:...392 were certified Class IE which are qualified.to LOCA. They also enclose the qualification report for Firewall III cables, dated July 7, 1977 which covers these cables.

Although the letter indicated P.O. #392 (spec. no. NAS-430) because all the cables were bought in the same time frame it has been concluded that all the c~bles in all the three specifications were co.vered by _this report. Cerro Cable Company revised the *same qualification report in Nov. 26, 1979, Dec. 8, 1980 and Dec. 23, 1980. (Ref. 27A) and called the same samples with the same name Firewall III cables with the insulation description as chemically cross-linked polyolefin instead of linked polyethylene.

They also provided their cation of Firewall III cables #RSS-3-021

. In Pkg. # 5437-51-01 we used one report for XLPE cables which was also prepared by Rockbestos in May, 1976 for the same Firewall III cable.
I From a detailed review of all the *above mentioned reports it has been concluded that Cerro Cable Co. prepared all 1 cables prior to 1978 by using chemically cross-linked polyethylene.
NRC Concerns 1) In reviewing the qualification cables FRC reviewed the various QDRs for the cables.The following table reveals the discrepancy:

-This is the only right QDR FRC reviewed for the right cable~
2) -*
FRC's general comment .is to get the applicability of the specific test report from the. vendor. In this regard as discussed in .Sec. 1 & 2 above we found the letters from the vendor which describe the material used for the subject cables and applicability of _the test report.

Conclusion:

By reviewing various test reports on Rockbestos XLPE cables from _1969 thru 1981 we found that all the :cables manufactured by them, have successfully passed the radiation and LOCA test, irrespective whether it was chemically or irradiationally cross-linked.

Based on this finding we have no discrepancies in the tions of the cables used in Surry _Pow.er Station.* This clarification of cable qualification should preclude* FRC concerns regarding the construction method used for the test cables, and the applicability _of the test reports as referenced.

ANALYSIS OF LOCA TEST Verification.of.?

days LOCA.Test (Described.in FRC -.Report No. F-C2857 dated Septernber.1970) Equivalent to the 'required operating time of 120 :day LOCA As shown on Fig. No. 10 .the test profile ABCDEF envelops the plant LOCA profile AGCHIJ for 7 days.* The *following analysis shows that the effect of test profile is* more severe than the required plant prQfile. As evident from the Fig. 10 the plant arnbieht temperature falls to 150°F after one hour and to 120°F after 48 hours. For conservatism we assumed 150°F LOCA temperature for all the 120 days of LOCA. The object of this analysis is to show that the effect of the test profile CDEF is equivalent or more to the required 120 days at 150°F (assumed for conservatism). The first hour of the test profile which envelops the required profile of the plant is neglected and only 11 hours of the test (profile CD) is converted to 150°F by using Arrhenius extrapolation.

a) Profile CD (Referring to Fig. 10) Arrhenius equations:

where T X _[ (T2-Tl) -K .Tl T2 T = time at an accelerated temperature= 11 hours X T = equivalent time at lower temperature= to be calculated La = Activation energy, EV (1.13 for XLPE per EPRI NP-1558 Final Report, Sept. 1980, Appendix B) K = Boltzmann's Constant= 8.617xlo 5 EV/°K T 2 = Elevated temperature= 276°F = 135°C + 273 = 408°K T. = Required temperature= 150°F = 65°C + 273 = 338°K 1 Substituting all the values 11 = TL e Solving: 1.13 (408:...338) 8-.617xlo-Sx408x338 TLa = 343 days

--* b) Profile EF (Referring to Fig. 10) T = 7 days. at 160°F X TLb=. 7 days (assumed same for conservatism)

Total Profile CDEF = TL = 343 :+ 7 = .350 days > 120 days

Conclusion:

i) As analyzed in above calculations it is obvious that the condudted test is equiv~lent to* 350 days of _LOCA at 150°F which is about 3 times the required operating time of 120 days after LOCA at 120°F. ii) A solution of Borated water (1720 ppm of boron as boric acid) was sprayed throughout the test.* Considering the above it is concluded that the condudted test is more severe than the required conditions of the plant.

1) cable construction methods (chemically cross linked or irradiationally cross-linked) used and 2) bility of the test reports to the subject cables. RESPONSE Continental Wire & Cable (Anaconda) correspondence letters included in the referenced QDR (included in attachment to this TER item also) were re-reviewed and the applicability of the test reports to various cables is established in the attachment of this TER Item No. 38. Per IEEE Paper dated May, 1969 "Insulation and Jackets for Control and Power Cables in Thermal Reactor Nuclear Generating Stations" the XLPE insulated are signated in:radiation class 3 (8.8x108 Rads) and mended for nuclear use for safety related equipment.

This equipment should be classified in Category Ia, "Equipment Qualified'~ ATTACHMENT TOTER ITEM N_O. 38 . VEPCO SURRY UNIT #1 QUALIFICATION OF 1000V, XLPE Continental Cables The qualification of .lOOOV, Continental cross linked polyethylene insulated cable is established in QDR~5437~6~~01.

1) These cables were bought under specificatioh .no. Nus~420 (SN-1463) in November 1971. 2) Attached Anaconda (same as Continental) letters dated July 14, 1978 and July 11, 1978 (also inbluded in referenced QDR on page* 3a) indicate that they used cc-2.210 FR-XLP compound for all their cross linked polyethylene cables which they supplied to VEPCO for Surry :Power Plants. 3) Anaconda supplied the *physical properties of CC-2210 cross linked polyethylene (used for Surry order) after various environmental conditioning, simulating a LOCA incident.

They also provided the radiation resistance curve vs the tensile strength and elongation which are good for 600V . cables thicknesses listed in Table I of Attach. *3 for section 3a of referenced QDR. 4) In attachment no. 3 of page 3a of the referenced QDR .5437-60-01 for Unit #1 (5437-130-01 for Unit #2) per Table I they supply 600V XLPE cables from 25 *mil's thickness to 78 mils of the same compound, qualified under the same curves which they provided with their July 11, 1978 letter. 5). As stated on page 11 of Section No. 1 of QDR-5437-60-01 (QDR-5437-130-01 for Unit #2) the insulation thickness of the compound used'. for the subJecE-----~ . cables is 45 mils,which is in between the values listed above in item 4. This indicates that the radiation curves and other physical property curves are applicable to this cable also.

Conclusion:

By considering the above facts we conclude that, because the same compound is used for the thicknesses listed in Anaconda's specification, the same qualification reports are applicable to these cables as to those ~~ich qualified 600 volt X~PE nental in the same QDR-5437.;..60-0l. (5437-130-01 for Unit #2) This clarification of the cable qualification should pre-clude FRC concerns regarding the construction methods used for the test cables and the applicability of the test reports as referenced.

Similarity Between: Test *Motors an:d Plant *Equipment: i) Westinghouse letter dated.4/9/81 in reference to letter NCW-1317/NAW-3615 (page 2d of QDR) indicates. that: a) The subject low head safety injection.pump motors were rewound in accordance with their insulation specification, LIT~spec-711306 (Page 26 of QDR-5437-105~01*). Since this specification was in use for several years before and after these motors were rewound, the probability for the use of other materials or procedures is minimal. b) The thermal endurance test of this thermalastic epoxy system was in accordance with IEEE Standard 275-1966 which describes the complete procedure (like cycle of oven aging, temperatures, aging time, mechanical, vibration, humidification, etc.). c) Test results show that this insulation system performed as well as the latest Class B lastic epoxy system. ii) Westinghouse letter no. NAW-3601 dated Aug. 19, 1980 (page 2c of QDR) indicates successful qualification testing of motors with thermalastic epoxy insulation systems, documented in WCAP-8754, including all organic insulating materials. Therefore wedges and cabling need not be addressed separately. The results of actual tests are available in Westinghouse fileso iii) Review of the insulation specification LIT-711306 (page 2c*of QDR-5437-105-01) indicates that tha insulation system consists of sheets of Mica embedded in a solvent-less epoxy resin which is the same as that described in Westinghouse WCAP-8754, Para. 4.2. iv) Westinghouse discussed thermalastic epoxy insulation in their application data 3170 (copy attached). Review of the insulation specification LIT-711306 used for the subject motors indicates that the lation materials, listed in the questioned tion are the same as discussed in their application date 3170. *Page 2c of Unit #1 QDR-5437-43-01 does not contain specification LIT-711306.

**
2. Considering the above it is concluded that the insulation system of .the subject motor is the same thermalastic epoxy. insulation as that of .the. test. specimen of Westinghouse WCAP-8754.

This* conclusion is further. *supported by_ *. the fact that all Westinghouse motors with thermalastic epoxy insulation system were wourid in .. accordance with . *r only one insulation specific~tion no. LIT-711306.

- Lubrication
Radiaticm Resistance and Aging Review of the plant maintenance records. confirms that for low head safety injection motor lubrication chevron SRI #2 has been used. The radiation resistance capabilities of Chevron SRI #2 is 1. 8x108 Rads per Westinghouse letter NAW-3620 dated Nov. 18, 1980. (included in the Ref. QDR). Because this qualification

~alue of l.8xl0 8 Rads envelops the plant required dose of 8.ox106 Rads, the subject motor lubrication are considered qualified for the tion. 3. Although an aging analysis was performed (see the attached analysis) a detailed maintenance, aging surveillance and replacement schedule will be*submitted. QUALIFIED LIFE OF WESTINGHOUSE LOW HEAD SAFETY INJECTION MOTORS 1) Westinghouse letter #VPU(RRK)-48 dated Jan. 9, 1981 (page 2d of the QDR) indicates that the actual maximum winding temperature rise from test is 70°C at 1.15 SF load for the Surry pump motors *. This gives a maximum continuous ing temperature of .110°c* (70+40) at the plant normal ambient temperature of 104°F (40°C). 2) Because the plant environmental conditions for the motors do not change duririg the_LOCA/HELB the same operating temperature (110 °C) is considered during normal as .well as during LOCA conditions.

3). These low head safety injection pump motors are required to operate during LOCA period of 120 days and periodic testing of about 2 hours a month. The total operating time during 40 yrs life *of the motor is calculated below .
**** i) Periodic*

testing during 40 .years -(2 hrs/month)x12x40 = :960 .hrs ii) LOCA period = 120 .days= 2880 hrs Total cOntinuous operation =(960+2880)~* 3840 hrs For conservatism it is assumed.in* the following analysis that the supject motor will run continuously for one year * (8760 hrs) instead of 3840 hrs. 4) From Fig. 4-1 of WCAP-8754 (thermal aging curv~ for lastic epoxy system, per IEEE Std. -275...:.1_966) the. qualified life at 120 °C = 200 ,.000 hours and from. Fig* *. 9-1. (in which . Westinghouse has drawn a most conservative projected qualified insulation life of motor) the qualified life at 120°C = 96,000 hours. 5) Activation Energy: The activation energy is calculated by Arrhenius tion as follows: From Fig. 9-1 .of WCAP-8754 the qualified*. life at 120 °.c = 90,000 hours and at 130°C = 45,000 *hours. Arrhenius equation where . (T2-Tl) -K Tl T2 Tx = life at a higher temperature T 2 = 45;000 hours. .TL = life at a lower temperature = 90;000 *hours. = activation energy = to be calculated Boltzman Constant -5. K = = 8.617xl0. T2 = Higher temperature = 130+273 = 403°K Tl = Lower temperature = 120+273 = 393°K

/ Substituting in the above equation:

44,000 Solving: *. :x (403-393} . 8.617x403x393xlo~5. -96,000 e -~ = 1.08==1.0

6) CALCULATION OF QUALIFIED LIFE:* From Fig. 9-1 of WCAP the qualified life *at 120°C is 96,000

hours. Out of this life the motor is* required to operate for 8,600 hours only. (see sec.* 3 above) *at 110°C:. Assuming it operates at 120°C, (for further conservatism) the ing analysis shows that the remaining continuous operating life of 87400 hours is more *than the* 39 years of how operating life at plant ambient of 40 °c* ( 104 °F)
Applying Arrhenius equation.

l (T2""'.Tl) -K T 1 xT 2 T = TLe X where: T = 87400 hours X TL = to be calculated Tl = (40 + 273) = 313°K T2 = (120*+ 273) = 292°K K -5 = 8.617xl0 = 1.0 (see sec. 5 above) Substituting: 87400 Solving: l.Ox(393-313) -8.617xlo-Sx393x313 = TL e TL= 659642 hours= 75 years

Conclusion:

From the above analysis it is concluded that the subject motors are .qualified for a life of at least 40 year.s under tpe specified service conditions of the plant. ' . ---*-----------------*-*-

A desc11ption of some of the more impor1ant tests follows. Electric Strength Smee the fundamental function of t1on is to withstand electric stress. tne first ,eries of tests on any insulation svstem 1s to determine its short-time electric strength. Complete insulated coils are use::l for this test. It 1s desirable that for any pani::::ular voltage class the av~rage breakdown voltage be as high as possible. However. it 1s essential that tne values be examined and analyzed 1>tat1st1cally. It 1s the Westinghouse concept tnat. using the principles of s1a:,st1cal analysis. the coils have a b!eakdown level well above the test level for indz\*idual coils. Thermalastic Epoxy insula?,o:i has both a higher average short-time electric stren;th and is more reproouc1ble frcm coil-to-co1I than .other insulation systems.

Voltage Endurance Smee 1nsulat1on in large machines is pected to perform for a long period of time. a voltage endurance test has been devised. In this test. sample coils aie prepared and connected as described for tne shon-t1me electric tests.
Electric strength is evaluated m deoth by a series of breakdown tests for each tion system. A group of sample coils for eacn svstem 1s tested at various voltage levels for fixed time intervals which may be one minute. one hour. one week or more. By planing average "hold"" values for the d1fferen:

time periods. a voltage enourance curve is created. Such a curve 1s shown ,n F,gure 3. Much of the data thus obtained tends to plot ,n a straight hne. One way of looking

al°such data 1s to estabhsn an **operating lever* and examine where tne extrapolated voltage endurance curve will intersect this **operating lever*. The Thermalast1c tion curve intersects the ope:at,ng stress level at a time in excess of 1 O:) years. Tnese are results of laboratory tes:s on only orie of the cegradtnl) mechanisms that atte:t insulatton and. therefore.

a*e not complete md1cat1ons of actual operating life. ever. systems that fail to g,ve indications of satisfactory life in this very fundamental test are not considered favorably. . Secor>d!. 'd & ~~or*~ HP"',. n1r*f"~f!r"f"f'fr~['l""l rr.J rrr*,1rrrrr

\ .. --:--~-; ' , . ..... __ Winding Repairs The standard1za11on of Thermalast:c Epoxy insulation for large motors allows a pletely new approach to the suoiect of winding repairs and the desirability of carrying spare cods. First of all. the poss1bd1ty of w1no1ng pairs beina required :s reduced to a mum far below that pOSS1ble With any VIOUS 1nsulat1on system. The basic approach 1s to crov1ce for the con!ingenc1es that may arise w:th minimum total expense to the user mciuo:ng both repair and oownt1me cost. Depending on the extent of daniage. several a!ternatives are available ior ing repairs: 1. Mcst failures resulting from accidental mechanical damage occur on tne end windings where the coil 1s exposed. pairs to the end winding external to the core can be made by the conventional patch1r.g method. 2. !n the remote pcss1bil1ty of coil fad1,Jre w;tn11, the slot. 1t 1s not practical to replace co:ls by conventional means. Tr.e very processing of complete 1mpregnat1on and bonding which insures a failure-free cod also makes 1t 1mpract1cal to 11ft enougn cods to replace both top and bonom cod sides of a dama_ged coil. To replace a damaged coil in any machine .. it has always been necessary to lift at least a full throw of coils to get the new coil in. Quite often. this operation results in age to a.her coils. Therefore. wnen spare coils.are considered desirable. it has been standard practice to carry at least % or of a set to replace one or two damaged cods. Westinghouse has developed a technique of cod replacement. for use on motors _manufactured at East Pittsburgh. which maices it unnecessary to disturb any coils except the damaged coil or. at most. the other coil in the same slot. For *Thermalastic Epoxy insulated machines. a standard* repair !cit can be supplied cluding six half cods suitable for replacing either top or bottom sides of the coil. Also included are. the necessary materials. tools and instrucuons for replacing damaged coils. Complete spare Thermalast1c Epoxy .. : . *:--* *::~~'~:,." "' Ml t,m,shod lo, th."' ....._. .

The elaborate facd-1t1es required* for tne Thermalast,c Eooxy system malce it necessary to re1urn the s:ator to the factor, to* obtain the original processing. On a breakdown basis. this can be cone usua!iy in three*weeks or less and requires no longer than woul.:J De recuire::1 to order coils and rewind 1n the field. If consideration 1s given to stocicing a full set of cods to oro1ect against such a failure on a Tnermalasuc Ecoxy insulated machine. the recor::mendat1on 1s that a complete wound stator be stocked. This will cost no more than a full set of cods plus the pense of stripping tne old winding and winding :he new cods in anv machine. Downtime is reduced to a m1n1mum.

Tag Nos: 1-C~-P-lA,lB & lC for Unit #1 QDR Nos: 5437-08-01 for. Unit #1 5437-69-01 for Unit #2 1. Similarity Between Test Specimen and the Eqliipmerit. i) Similarity between the motor lead insulation of the test specimen and the equipment: a) Westinghouse letter no. NAW-3615 dated Oct. 30, 1980 (included in the referenced QDR, page* 3a) indicates on page 2 that the Surry pump motor insulation for the charging pumps:is thermalastic epoxy and the qualification is covered by WCAP-8754. ii) Similarity between the motor lead insulation of the test specimen and the equipment: a) Westinghouse letter no. NAW-3620 (included in the referenced QDR, page 2c) indicates that for the motors which employ the thermalastic epoxy tion system, the testing documented in WCAP-8754 includes all organic insulating materials in the motor. Therefore wedges and cabling need not be addressed separately for these motors. b) The therrnalastic epoxy system, .developed by. Westinghouse and first put into service *in 1962, (see WCAP-8754, Para. 4-2) and only _one insulation specification, LIT-711306, were in use for winding motor coils (see QDR-5437-08-01, Section 2, Page 2b}, it has been determined that these motors had motor to leadsplice materials as discussed in specification LIT~711306. Specification LIT-711306: l~ad in~ulation and tying (page 3 of 14), winding procedure (paragraph 29, page 5 of 14), aQd sketches D and E (page 11 of 14) indicate the use of sleeving (M#41524-AV), resin tape (M#9948-3), micatape (M#43865-AD), and glass tape (M#41514~CT) as the motor to leadsplice materials. These materials are in fact the terials used when winding the subject motor coils . -* 2. -~

c) d)-Westinghouse letter dated April 9, 1981, in reference to letters NCW-1317 and NAW-3615, states that motorettes using an insulation system similar to the one prescribed in the rewind specification* (LIT~711306) were tested for thermal performance in accordance with IEEE 275. This is basically the same test: as described i-n paragraph 4-~3 of _WCAP-8754-p~r IEEE 275~1966.

Therefore the motor to leadsplice materials were tested, as part of the formettes, for thermal endurance to determine the resistance of the thermalastic epoxy system to thermal aging, following the guidelines for accelerated tional testing, as outlined in IEEE 275-1966.

In addition to the above the review of _WCAP-7_829, table #22, page 46 indicate that the motor lead cable is silicone rubberized glass*taped tion.* This is the same as indicated in house insulation spec. LIT-711306.

The same is confirmed from Westinghouse tion Data 3170 (copy attached). Considering the above facts it is concluded that the motor lead insulation of the subject motor is the same as the test specimen of WCAP-8754 and 7829. Lubrication Radiation Resistance and Aging Review of the plant records shows that Exxon-Teresstic-46 has been used for charging pump motor lubrication.* The radiation resistance capabilities of Exxon-Teresstic-46 is 1.4xlo7 Rads per Westinghouse letter no. NAW~3615 dated October 30, 1980 {copy attached). The worksheets will be revised to reflect the overall radiation resistance qualification of the motors as l.4xl07 Rads. Because this qualification value of 1.4xlo 7 rads envelops the plant total required dose of *1.4x106 rads, the subject motors are considered qualif'ied for the radiation

3. Although an aging analysis is performed (see the attached analysis}

a detailed maintenance piocedures and aging surveillance and replacement schedule will be *submitted. QUALIFIED LIFE OF WESTINGHOUSE CHARGING ~UMP MOTORS . 1) Westinghouse letter rio. VPU(RRK)-48 dated Jan. 9, 1981 (page 2c of the QDR) indicates that the actual maximum winding temperature rise from test is 70°C at 1.15 SF load for the Surry pump motors. This gives a maximum continuous operating-temperature of 110°C (70+40) at the plant normal ambient temperature of 104°F(40°C).

2) Because the plant environmental conditions for the motors do not change during the .LOCA the same operating ture (110°C) is considered during normal as well as .during LOCA conditions.

During HELB conditions the ambient temperature goes to 140°F (from 104°F normal) for one hour. 3) Out of the three charging pumps one pump is required to operate continuously during the plant operation. It is conservative to assume that each pump motor will operate continuously for 14 years and remain idle for 26 years., .In.the following analysis it is shown that the qualified life of the motor is more than the required 14 years of continuous operafing and 26 years of non o~erating lives. 4) From Fig. 4-1 of WCAP-8754 (thermal aging curve for lastic epoxy system, per IEEE Std.-275-1966) the qualified life at 120°C = 200,000 hours and from Fig. 9-1 (in which Westinghouse has drawn a most conservative projected fied insulation life of motor) the qualified life at 120°C = 96,000 hours. 5) Activation Energy: The activation energy is calculated by Arrhenius tion as follows: From Fig. 9-1 of WCAP-8754 the qualified life at 120°C = 90,000 hours and at 130°C = 45;ooo hours~

Arrhenius equation .[ -*.K where (T2 ~TI) Tl _T2 Tx = life at *a higher temperature=

45;000 hours TL = life at a lower. temperature = 90;000 hours = activation energy = to be calculated

K = Boltzman Constant = 8.617xlo'°':

5 T2 = higher temperature = 130 + 273 Tl = lower temperature = 120 + 273 Substituting in the above equation: 44,000 = 96,000 Solving: ~x (403-393)

-a.167x403x393xl0 5 e = 1.08 == 1.0 6) Calculation of Qualified Life* = 403°K = 393°K i) From Fig. 9-1 of WCAP-8754 the qualified life at 120°C is 96,000 hours. This life is converted at 110°C (which is maximum operating temp of the motors per Westinghouse letter no. VPU(RRU)-48 dated Jan. 9, 1981) by using Arrhenius extrapolations:

Arrhenius equation .[ (T 2-Tl) -K T 1 xT 2 T = TL e X where T = 96,000 hours X TL = to be calculated T2 = 120°C + 273 = 393°K Tl = *110°c + 273 = 383°K 0 = 1. 0

Substituting the. values 1. 0 X (393:_;383)

-8.617xlo~sx3~3x383 96,000 = T e L Solving: TL= 207,542 hours= 23.69 years Conclusions Hence the qualified life of the motor at 110°C is 23.69 years. Out of this the motor is_required to r~n continuously for 14 years. For conservatism let us assume that it operated continuously for 20 years at 11o~c. ii). Now in the following calculations it is shown that the life of 3.69 years (23.69 -20) at 110°C is much more severe than the required 20 years of non operating life at plant ambient temp. of 40°C. Tx = 3.69 years= 32324 hours TL= to be calculated T 2 = 110°C + 273 = 383°K Tl= 40°C + 273 = 313°K Substituting in the Arrhenius equation 1.0 X (383-313) -8.617x383x313xlo~5 32324 = T e L Solving TL = 3235 years > 20 years.

L, _____ .,_ ____ ..,._*~-Evaluation and Test Program lnermalast1c Epoxy insulation was adopted as standard for large a:: moto:s only efter c.lmplet1on of an ex.ensive evaluat,on and test program. A desc11ption o! some of the more imponant tests follows. Electric Strength Smee the fundamen1al function of tion is to withstand electric s:ress. me !1rs1 ,eries of tests on any msulat1on svstem 1s 10 determine its sholi-l1me electric strength. Complete insulated coils are used fc,: tn1s test. It 1s des11a:ile that for any pa:1;cula1 voltag= class the average breakdown voltage be as high as possible. However. rt rs essential that tne values be examined and analyzed &tat1st1cally. It 1s the Westinghouse concept that. using the p11nc1ples of s:a:,s:1cal iinalys:s. the coi!s have a b*ea~down level well above the test level 1or rnd1\*ioual coils. Thermaiastic Epoxy insula!,C!"l has botf-i a higher average shon-11me ele::t11c stre!"l,llh end 1s more reproou::,bie frcm co*l-to-co1l than other insulation svstems. Voltage Endurance Smee insulation 1n large ma:hines is pe:ted to perform for a long pe11od of ume. a voltage endurance test has been de-.,1se::. In this test. sample coils are prepared and conne::te:i as described for tne shor1-t1me elec:mc tests. Eie:tr1c strength is evaluate:i rn de:::-th by a series of brea~down tests for each tion system. A group of sample coils for ea::n svstem 1s tested a: various voltagi? leve!s for fixed time intervals which may be one minute. one hour. one weeic or more. By pionmg average .. hot:r* values for the d1fieren: time periods. a voltage er.:uran::e cur\'e is created. Such a cur.-e ,s shown 1n Figure 3. Mu:h of the data thus obtained tends to plot in a straight line. One way of looking at such data 1s to estabhsr, an .. operating level .. and examine where tne. extrapolated voltage endurance curve will mte*se:t this .. opera11ng lever*. The Tt>ermalasl!c tion cu*ve intersects the ooerat,ng sHess level at a time in ex::ess of 1 O:) years. T nese are results of labora:ory tes:s on onlv or,e of the oegrao1n'1 mechanisms that atte:t msulat1on and. therefore. a*e not complete md1cat1ons of actual ooera:ing ltfe. ever. systems that fail to g, .. e mdicat:ons of sat1sfa:tory life rr. this very fundamental test are not considered favorably. s~orc.. d 6::.::,~r' 1rrr IF r:rir-rr1Jr~r'1P"rrr1rrr*1rr 11 rr .

It is concluded that all.of these concerns are resolved except Aging and Qualified Life. As recommended in the QDR, the penetrations should be included in a surveillance* program. The TER assigns other equipment of this sort to Category IIc .

ATTACHMENT TO SURRY 1 ITEM 7 AMPHENOL PENETRATIONS A. CONCERN: (1) Similarity Between Equipment and Test Specimens

*----**--

-*-* --(pa*ge* of--TER)-------~------*-

**--------

-*----------

.

- ------(2) It is not clear why the manufacturer was not contacted to determine the applicability of the test reports. It is noted that Amphenol has provided test documentation to other plants, i.e., Calvert Cliffs, Trojan, San Onofre, Davis Besse and ANO (page Sf of TER) RESOLUTION:

The Amphenol penetrations used at Surry are of the canister type, rather than the unitized header design supplied for later plants such as Davis Besse and AN0-2. Copies of ten references are attached documenting tacts with Amphenol to obtain copies of suitable test reports for the canister design (which they could not prcvi de..) or for the uni ti zed header design (which were ultimately obtained directly from Toledo Edison and Arkansas Power & Light). Additionally, the referenced QDR contains tial documentation relating the canister and unitized header designs. In particular, the "Design Evolution" report included with the original Amphenol proposal in Section 2b of the QDR provides a detailed description of Amphenol's penetration design evolution from canister to unitized header. The photographs and drawings in this report, together with the drawings in the Proposal~ clearly establish that at the time Surry penetrations were fabricated the two designs employed the the same connector modules, insulation materials, potting compounds, and sealants; only the structural metallic components in which these items are mounted and related welds differ. Amphenol's Design Verification Test Report, included in Section 3d of the QDR, summarizes the reasons for evolving from the canister to the unitized header design (page 1): "The unitized header assembly (UHA) offers the advantages of a lighter, more compact unit than the canisters which have been used heretofore and also vides for versatility and interchangeability of ents. In addition, the UHA promises to considerably reduce the required field installation effort." Sheet 10 of the QDR, reproduced on page Sf of the TER, documents additional comparisons performed by NUS to.verify the similarity between Surry equipment and the test specimens used for the test reports empl9yed by the QDR .

t:.., __ _ *

Summarizing, the manufacturer was contacted edly to obtain applicable test reports. In the absence of complete test reports for the canister design used at -*-*-----*-*--Surry;-

d-es-i-grc similarity to the tested unitized header** penetrations was established using information pro-vided by the manufacturer. Test reports for the unitized header penetrations were obtained and used to establish the qualification of the Surry penetrations. This effort adequately determines similarity between the plant ment and test specimens in conformance to the DOR Guide-lines.

B. CONCERN: (1) Aging Degradation Evaluation (page 2 of TER) (2) Qualified Life or Replacement Schedule Established (page 2 of TER) * (3) No aging evaluation has been conducted (page Sh of TER) RESOLUTION:

Sheet 11 of the QDR, reproduced on page Si of the TER, summarizes the thermal cycle test in Amphenol report_ 123-1275 but does not provide an Arrhenius calculation to. predict a qualified life. Clearly such a calculation would predict a very long life: for example, using the conservative activation energy of 0.7 ev developed on sheet 13 of the QDR, the one hour of thermal testing at 400°F corresponds to over 1,000 years at the compartment ambient of 105°F. The QDR concluded that the evidence is not sufficient to justify a 40 year qualified life, and an Ongoing Aging Surveillance Program should be performed. This_ deficiency by itself would not cause the penetrations to be fied in TER category IIa. category IIc, "Qualified Life Deficiency," would be appropriate . -._....,._ -.. ***--. ---.. -*

C. CONCERN: (1) Temperature/Pressure Test Duration (TER page 2) (2) Temperature/Pressure Required Profile Enveloped

___________

by Test Prof.ile. _(TER.page_ 2.) ____ _ ____________________________ _ (3) Note 5 states that two referenced tests envelop_ neither the peak temperature nor entire tion, while a third referenced test which ceeds the peak temperature does not have quate duration. (TER page Sj; test and plant~

profiles reproduced on pages Sk through Sn). RESOLUTION:

This concern primarily reflects the fact that in 1972 the industry did not conduct 120-day LOCA tests; secondarily, the pea~ temperature in the Davis Besse LOCA test (the most closely related test to Surry LOCA conditions) is slightly lower than for Surry. This cern is not considered significant for the reasons that follow. The Surry peak LOCA temperature for the penetrations is 280°F for 30 minutes. It decays to 150°F in the next 30 minutes, then to 120°F by the ~nd of two days and remains at 120°F for the balance of the 120 day post-LOCA required operating period. Attachment No. 2 of the QDR presents a series of Arrhenius calculations to show that the Davis Besse LOCA test is more severe than the Surry LOCA. This is shown by converting both profiles to equivalent time at 120°F, using a conservative actiation energy of 0.7 ev. The calculations show that the Davis Besse test corresponds to an additional two month~ of post-LOCA operation at Surry after the required 120 day operating time. The two LOCA profiles, shown in Figure 13 of the QDR, do not differ significantly, and this approach is not considered to represent an abusive use of the Arrhenius technique. Since the Davis Besse test did not bound the Surry peak temperature, the QDR also referred to Amphenol's "Maximum Credible Accident" test. In this test the penetrations experienced 300°F for 15 minutes dropping to 250°F for the balance of 24 hours. The thermal aging test discussed under the aging concern exposed the trations to seven hours at or above 300°F; this test was performed in dry air rather than steam. These two tests provide substantial evidence that threshold effects or other adverse behavior will not occur in the small portion of the Surry LOCA peak not enveloped by the Davis Besse test . ------****---*

- --.. --**-*-*'
*
With respect to the concern that Arrhenius lations should not be used to extrapolate ture, saturated steam exposure to low temperature, oxygen-rich operation,_

two points are noted: Fir.st, __ in Attachment _________

No. 2 of the QDR it is evident th~t most of the "credit" for post-LOCA operating time derives from testing at or below 180°F, which does not reflect a steam environment.

Second, the aging just:ifies many years operation at am-bient temperature, based on the oxygen-rich thermal aging test. It is noted that the QDR contains.an

error in senting LOCA test results.*

For the Davis Besse test both temperatyre and duration values used are incorrect because the test procedure rather than the test report was used. The TER presents correct conditions. In spite of the error the results of the calculation in Attachment No. 2 of the QDR remain valid (lower temperature and longer time tend to offset), but the QDR will be corrected. Summarizing, the justification for LOCA tion of the penetrations is considered valid. D. CONCERN: (1) Spray (page 2 of TER) (2) "Boric acid was mixed and boiled to make steam. No spray was used." (page Sj of TER) RESOLUTION: The direct impingement forces of droplets from tainment spray nozzles become insignificant relative to LOCA pressures beyond one or two feet from the nozzle. The Surry penetrations are located no closer than several feet from spray nozzles. Thus the spray test is sidered to have adequately simulated the Surry LOCA vironment even though the solution was not directly sprayed through a nozzle into the test chamber. E. CONCERN: RESPONSE: (1) (2) Radiation (TER page 2) Note 4 challenges the qualified radiation dose of l.03xlo8 rads claimed in the QDR (TER page Si) The TER presents (on page Sh) documentation from the Hanford laboratory showing that, although portions of the test container received l.03xlo8 R, other portions received as little as 1.22xl0 7 R. The TER further sents on page Sh a caution that radiation exposure was quoted in Roentgens and would have to be converted to rads to reflect absorbed dose. The required radiation dose for the Surry penetrations is 7.44xlo6 rads (40 years plus LOCA). The conversion from Roentgens to rads for the organic materials of cern is unlikely to vary from 1.0 by more than ten to twenty percent, so the qualified dose is at least lxlo7 rads. This exceeds the plant environment. -' Stone G Kcbstcr 225 Franklin Strc~t Boston, Mnss~chusetts 02107 ,\ t tent i on : A. W.

1) cable construction methods (chemically cross linked or irradiationally cross-linked) used and 2) bility of the test reports to the subject cables. RESPONSE Cont1nental Wire & Cable (Anaconda) letters included in the referenced QDR (also included as an attachment to this TER item) were re-reviewed and the applicability of the test reports to the subject cables has been established.

Per IEEE Paper dated May, 1969 "Insulation and Jackets for Control and Power Cables in Thermal Reactor Nuclear Generating Stations" the XLPE insulated are designated in radiation class 3 (8.8xl08 Rads) and recommended for nuclear use for safety related equipment. This equipment should be classified in Category Ia, "Equipment Qualified".

This clarification of the cable qualification should preclude FRC concerns regarding the construction methods used for the test cables and the applicability of the test reports as referenced.

ATTACHMENT TOTER ITEM NO. 41 VEPCO SURRY UNIT #2 QUALIFICATION OF 1000V, XLPE Continental Cables The qualification of lOOOV, Continental (Anaconda) cross linked polyethylene insulated cable is ~stablished in QDR-5437-60-0l.

1) These cables were bought under specification no. NUS-420 (SN-1463) in November 1971. 2) Attached Anaconda (Continental) letters dated July 14, 1978 and July 11, 1978 (also included in referenced QDR on page 3a) indicate that they used CC-2210 FR-XLP compound for all their cross linked polyethylene cables which they supplied to VEPCO for Surry Power Plants.

3) Anaconda supplied the physical properties of CC-2210 cross linked polyethylene (used for Surry order) after various environmental conditioning, simulating a LOCA incident.

They also provided the radiation resistance curve vs the tensile strength and elongation which are good for 600V cables thicknesses listed in Table I of Attach. 3 in page 3a of referenced QDR. 4) In attachment no. 3 of page 3a of the referenceq. QDR. 5437-60-01 for Unit #1 (5437-13Q-Ol for Unit 12i per Table I they supply 600V XLPE cables from 25 mil's thickness to 78 mils of the same compound, qualified under the same curves which they provided with their July 11, 1978 letter. 5) As stated on page 11 of Section-No. 1 of the referen~ed QDR-5437-60-01 (QDR-5437-130-01 for Unit #2) the tion thickness of the compound; used for the subject cables is 45 mils which is in between the values listed above in item 4. This indicates that the radiation curves and other physical property curves are.applicable to this cable also.

Conclusion:

After considering the above facts we conclude that, because the same compound is used and the thicknesses meet Anaconda's specification, the same qualification reports are applicable to these cables which qualified 600 volt XLPE Continental as shown in QDR-5437-60-01 (5437-130-01 for Unit #2).

They included one sample of "Pyro-Trol III" cable also with the same product code 655N30 series (30 mils of flame retardant cross-linked polyethylene insulation thickness). This report addressed radiation (from 55 Mrad thru 179 Mrad), humidity, steam press. & chemical spray test for 7 days. The spray test of seven days is quite severe to justify the LOCA requirement of the plant (see the attached analysis). Our QDR will .be revised to reflect the review of the s~bject cables per these reports and the Franklin Report #F-C3798 which is used to qualify these cables will be deleted. 2. 300V & 600V, XLPE Cables: (QDRs-5437-50-01,51-0l,53-01 for Unit #1!

2 Originally these 300V & 600V, XLPE cables were bought for N. Anna power plant but later were transferred to Surry power _plant for the required use. These were bought under the following 2 different cations: i) Specification No. NAS-120, (P.O. #NA-312/1312), dated Oct. 1969 thru March, 1972. ii) Specification No. NAS-3187, {P.O. #NA-3187/4183), dated Oct. 11, 1973. iii)Specification No. NAS-430, (P.O. #NA-392/1392), dated June, 1974. Qualification of cables in Spec. NAS-120, NAS-3187, & NAS-430 is addressed in QDR #s. 5437~50-0l, 5437-51-01

& 5437-53-01 respectively for Unit #1 (QDR #5437-118-01, 5437-119-01, 5437-121-01 for Unit #2) . -*--.. --. ~--*---. ,-.. --... -----... ,,....--.. ------------------. *--*** --.:..

NA-3187/4187 -May~-1, 1976 thru Nov. 1976. Cables under Spec. NAS-430, P.O. NA-392/1392 -June 24, 1974 thru Aug. 1978. ii} Rockbestos Comp. wrote a letter to S&W on Feb. 21, 1979 which indicates that the cross-linked polyethylene cables supplied under P.O. NA-392 were certified Class IE which are qualified to LOCA. They also enclose the qualification report for Firewall III cables, dated July 7, 1977 which covers these cables. Although the letter indicated P.O. #392 (spec. no. NAS--430) because all the cables were bought in the same time frame it has been concluded that all the cables in all the tnree specifications were covered by this report. Cerro Cable Company revised the same qualification report in Nov. 26, 1979, Dec. 8, 1980 and Dec. 23, 1980. (Ref. 27A) and called the same samples with the same name Firewall III cables with the insulation description as chemically cross-linked polyolefin instead of linked polyethylene. They also provided their cation of Firewall III cables #RSS-3-021. In Pkg. # 5437-51-01 we used one report for XLPE cables which was also prepared by Rockbestos in May, 1976 for the same Firewall III cable. From a detailed review of all the above mentioned reports it has been concluded that Cerro Cable Co. prepared all cables prior to 1978 by using chemically cross-linked polyethylene.

2) FRC's general conunent is to get the applicability of the specific test report from the vendor. In this* regard as discussed the letters from the vendor which describe the material used for the subject cables and applicability of the test report.

Conclusion:

By reviewing various test reports on_Rockbestos XLPE cables from 1969 thru 1981 we found that all the cables manufactured by them, have successfully -passed the radiation and LOCA test, irrespective whether it was chemically or .irradiationally cross-linked. Based on this finding we have no discrepancies in the tions of the cables used in Surry Power Station. This clarification of cable qualification should preclude FRC concerns regarding the construction method used for the test cables, and the applicability of the test reports as referenced. . .. *-***. . -.. *. . . **-~ . . . ---------------..... --------****-----------*--. --j

.. -------*--*--*-**--------------------------*-

--*------- As shown on Fig. No. 10 the test profile ABCDEF envelops the plant LOCA profile AGCHIJ for 7 days. The following analysis shows that the effect of test profile is more severe than the required plant profile. As. evident from the Fig. 10 the plant ambient temperature falls to 150°F after one hour and to 120°F after 48 hours. For conservatism we assumed 150°F LOCA temperature for all the 120 days of LOCA. The object of this analysis is to show that the effect of the test profile CDEF is equivalent or more to the required 120 days at 150°F (assumed for conservatism)

. The first hour of the test profile which envelops the required profile of the plant is neglected and only 11 hours of the test (profile CD) is converted to 150°F by using Arrhenius extrapolation.

a) Profile CD (Referring to Fig. 10) Arrhenius equations: where T X f (T2-Tl) -K Tl T2 T = time at an accelerated temperature= 11 hours X T = equivalent time at lower temperature= to be calculated La (J = Activation energy, EV (1.13 for XLPE per EPRI NP-1558 Final Report, Sept. 1980, Appendix B) K = Boltzmann's Constant= 8.617xlo 5 EV/°K T 2 = Elevated temperature= 276°F = 135°C + 273 = 408°K Tl -Required temperature = 1s*o°F = 65°C + 273 = 338°K substituting all the values 11 = TL e Solving: 1.13 (408:...338)

Conclusion:

i) As analyzed in above calculations it is obvious that the c6nducted test is equivalen~ to 350 days of LOCA at l50°F which is about 3 times the required operating time of 120 days a!ter LOCA at 120°F.

ii) A solution of Borated water (1720 ppm of boron as boric acid) was sprayed throughout the test. Considering the above it is concluded that the conducted test is more severe than the required conditions of the plant . . ,. --~-. ' -.. : ... ** ... ___ -__ _

ATTACHMENT TOTER ITEM #50 (VEP-CO SURRY UNIT # 2 ) LOW HEAD SAFETY INJECTION PUMP MOTORS (Tag Nos. 1-SI-P-lA,lB)

Tag Nos: 1-SI-P-lA,lB & 2-SI-P-lA,lB QDR Nos: 5437-43-01 for Unit #1 and 5437-105-01 for Unit #2 1. Similarity Between Test Motors and Plant Equioment: i) Westinghouse letter dated 4/9/81 in reference to letter NCW-1317/NAW-3615 (page 2d of QDR) indicate that: a) The subject low head safety injection pump motors were rewound in accordance with their insulation specification, LIT-Spe6-711306 (Page 26 *of QDR-5437-105-01*). Since this specification was in use for several years before and after these motors were rewound, the probability for the use of other materials or procedures is minimal. b) The thermal endurance test of this_ thermalastic epoxy system was in accordance with IEEE Standard 275-1966 which describes the complete procedure (like cycle of oven aging, temperatures, aging time, mechanical, vibration, humidification, etc.). c) Test results show that this insulation system performed as well as the latest Class B iastic epoxy system. ii) Westinghouse letter no .. NAW-3601 dated Aug. 19, 1980 (page 2c of QDR) indicates successful qualification testing of motors with thermalastic epoxy insulation systems, documented* in WCAP-8754, including all organic insulating materials. Therefore wedges and cabling need not be addressed separately. The results of actual tests are available in Westinghouse files. iii) Review of the insulation specification LIT-711306 (page 2c of QDR-5437-105-01} indicates that the insulation system consists of sheets of Mica embedded in a solvent-less epoxy resin which is the same as that described in Westinghouse WCAP-8754, Para. 4.2. iv} Westinghouse discussed thermalastic epoxy insulation in their application data 3170 (copy attached). Review* of the insulation specification LIT-711306 used for the subject motors indicates that the lation materials, listed in the questioned tion are the same as discussed in their application date 3170. *Page 2c_of Unit #1 QDR-5437-43-01 does not contain specificati?n

LIT-711306.
*-* Considering the above it is concluded that the insulation system of the subject motor is the same thermalastic epoxy insulation as that of the test specimen of Westinghouse WCAP-8754-.-

--This -conclusion .is _further _supported .with_ the ______________ _ fact that all Westinghouse motors with thermalastic epoxy insulation system were wound in-accordance with the only one insulation specification no. LIT-711306.

2. Lubrication Radiation Resistance and Aging Review of the plant maintenance records confirms that for low head safety injection motor lubrication chevron SRI #2 has been used. The radiation resistance capabilities of

Chevron SRI #2. is 1. 8xlo8 Rads per Westinghouse letter NAW-3620 dated Nov. 18, 1980 (included in the Ref. QDR). Because this qualification value of 1.8xlo 8 Rads envelops the plant required dose of 8.0xlo6 Rads, the subject motor lubrication are considered qualified for the tion. 3. Although an aging analysis was performed (see the attached analysis) a detailed maintenance, aging surveillance and replacement schedule will be submitted . . QUALIFIED LIFE OF WESTINGHOUSE LOW HEAD SAFETY INJECTION MOTORS 1) Westinghouse letter #VPU(RRK)-48 dated Jan. 9, 1981 (page 2d of th2 QDR) indicates that the actual maximum winding temperature rise from test is 70°C at 1.15 SF load for the Surry pump motors. This gives a maximum continuous operat-_ ing temperature of 110°C (70+40) at the plant normal ambient temperature of ~04°F (40°C). 2) Because the plant environmental conditions for the motors do not change during the LOCA/HELB the same operating temperature (110°C) is considered during normal as well as during LOCA conditions.

3) These low head safety injection pump motors are required to operate during LOCA period of 120 days and periodic testing of about 2 hours a month. The total operating time during 40 yrs life of the motor is calculated below . .. .-----.... *-*--

i) Periodic testing during 40 years= (2 hrs/month)xl2x40

---*--* .... *-.-= 960 hrs ii) LOCA period = 120 days= 2880 hrs Total continuous operation

(960+2880)

3840 hrs For conservatism it is assumed in the following analysis that the su~ject motor will run continuously for one year (8760 hrs) instead of 3840 hrs. 4) From Fig. 4-1 of WCAP-8754 (thermal aging curve for lastic epoxy system, per IEEE Std.-275-1966) the qualified life at 120°C = 200,000 hours and from Fig. 9-1 (in which Westinghouse has drawn a most conservative projected qualified insulation life of motor) the qualified life at 120°C = 96,000 hours. 5) Activation Energy: The activation energy is calculated by Arrhenius tion as follows: From Fig. 9-1 of WCAP-8754 the qualified life at 120°C = 90,000 hours and at 130°C = 45,000 hours. Arrhenius equation where T = X TL = = K = T2 = Tl = (T2-Tl) -K Tl T2 life at a higher temperature T2 = 45,000 hours. life at a lower temperature = 90,000 hours. activation energy = to be calculated Boltzman constant = 8.617xl0-S Higher temperature = 130+273 = 403°K Lower temperature = 120+273 = 393°K **--------*------*--*-~--. --.. -. **-..... --****------------, .... *******-----**-****---------*******-* . -_._ -. ---.. --:--. -* . -*--------*-**---

Substituting in the above equation:

0 x. (403-393) 44,000 = 96,000 e Solving: 8-. 617x40 3x39 3xlo--5-0=1.08-==l.O

6) CALCULATION OF QUALIFIED LIFE: From Fig. 9-1 of WCAP the qualified life at 120°C is 96,000 hours. Out of this life the motor is required to operate for 8,600 hours only (see sec. 3 above) at 110°C. Assuming it operates at 120°C, (for further conservatism) the ing analysis shows that the remaining continuous operating life of 87400 hours is more than the 39 years of how operating life at plant ambient of 40°C (104°F). Applying Arrhenius equation.

where: T = X TL = Tl = T2 = K = Q_ (T2-Tl) -K T 1 xT 2 87400 hours to be calculated ( 40 +_ 273) = 313°K (120 + 273) = 292°K 8.617xlO -5 0 = 1.0 (see sec. 5 above) Substituting: 87400 Solving: l.Ox(393-313) -8.617xlo-Sx393x313 = TL e TL= 659642 hours= 75 years

Conclusion:

From the above analysis it is concluded that the subject motors are qualified for a life of at least 40 years under the specified service conditions of the plant.

One basic feature of Thermalast1c Epoxy insulation rs the use of mica in the ground wall. No other material can equal m,ca from the s:an:i:::,omt of electric strength. voltage endurance and reliabilrty. Solventless epoxy resins ere impregnated into the mica whrch has been prepleced on I form-wound coil. Then with both mica and resin in position. chemical re-11ction is initiated which transforms the re-.1n into a sol,d which locks end binds the m1-..., into 8 composite mass. The ing end product then tal;es advanta;;e of the excellent properties of both the mica and the resin.

& lC for Unit #1 QDR Nos: 5437-08-01 for Unit #1 5437-~9-0l for Unit #2 1. Similarity Between Test Specimen and the Equipment. i) Similarity between the motor lead insulation of the test specimen and the equipment: a) Westinghouse letter no. NAW-3615 dated Oct. 30, 1980 (included in the referenced QDR, page 3a) indicates on page 2 that the Surry pump motor insulation for the charging pumps is thermalastic epoxy and the qualification is covered by WCAP-8754. ii) Similarity between the motor lead insulation of the test specimen and the equipment: a) Westinghouse letter no. NAW-3620 (included in the referenced QDR, page 2c) indicates that for the motors which employ the thermalastic epoxy tion system, the testing documented in WCAP-8754 includes all organic insulating materials in the motor. Therefore wedges and cabling need not be addressed separately for these motors. b) The thermalastic epoxy system, developed by Westinghouse and first put into service in 1962, (see WCAP-8754, Para. 4-2) and only one insulation specification, LIT-711306, were in use for winding motor coils (see QDR-5437-0B-Ol, Section 2, Page 2b), it has been determined that these motors had motor to leadsplice materials as discussed in specification LIT-711306. Specification LIT-711306: lead insulation and tying (page 3 of 14), winding procedure (paragraph 29, page 5 of 14), and sketches D and E (page 13 of 14) indicate the use of sleeving (M#41524-AV), resin tape (M#9948-3), micatape (M#43865-AD), and glass tape (M#41514-CT) as the motor to leadsplice materials. These materials are in fact the terials used when winding the subject motor coils . --.------,.-*-*--*-

~--. ----------------. -*-~---

c) d) Westinghouse letter dated April 9, 1981, in* reference to letters Nci-v-1317 and N.Z:1.W-3615, states that motorettes using an insulation system simil~r to the one prescribed in the rewind--spec-if-ica tion--(L-IT-7-1-1306

)--were--tested** for thermal performance in accordance with

IEEE 275. This is basically the same as described in paragraph 4-3 of WCAP-8754 per IEEE 275-1966.

Therefore the motor to leadsplice materials were tested, as part of the formettes fo~ thermal endurance to determine the resistance of the thermalastic epoxy system td thermal aging, following the guidelines for accelerated tional testing, as outlined in IEEE 275-1966. In addition to the above the review of WCAP-7829, table #22, page 46 indicate that the motor lead cable is silicone rubberized glass taped tion. This is the same as indicated in house insulation spec. LIT-711306. The same is confirmed from Westinghouse Applica-tion Data 3170 (copy attached).

Considering the above facts it is concluded that the motor lead insulation of the subject motor is the same as the test specimen of WCAP-8754 and 7829. *** 2. Lubrication Radiation Resistance and Aging * ---. -.. . Review of the plant records shows that Exxon-Teresstic-46 .has been used for charging pump motor lubrication.

The radiation resistance capabilities of Exxon-Teresstic-46 is 1.4xlo7 Rads per Westinghouse letter no. NAW-3615 dated October 30, 1980 (copy attached). The worksheets will be revised to reflect the overall radiation resistance qualification of the motors as l.4xlo7 Rads. Because this.qualification value of 1.4xlo 7 rads envelops the plant total required dose of 7.4xlo6 rads, _the subject motors are considered qualified for the radiation .

3. Although an aging analysis is performed (see the attached analysis) a detailed maintenance procedures and aging surveillance and replacement schedule will be submitted.

QUALIFIED LIFE OF WESTINGHOUSE CHARGING PUMP MOTORS 1) Westinghouse letter no. VPU(RRK)-48 dated Jan. 9, 1981 (page 2c of the QDR) indicates that the actual maximum winding temperature rise from test is 70°C at 1.15 SF load for the Surry pump motors. This gives a maximum continuous operating temperature of 110°C (70+40) at the plant normal arr~ient temperature of 104°F(40°C).

2) Because the plant environmental conditions for the motors do not change during the LOCA the same operating terr~era~

ture (110°C). is considered during normal as well as during LOCA conditions. During HELB conditions the ambient temperature goes to 140°F (from 104°F normal) for one hour only. 3) Out of the three charging pumps one pump is required to operate continuously during the plant operation. It is conservative to assume that each pump motor will operate. continuously for 14 ye~rs and remain idle for 26 years. In the following analysis it is shown that the qualified life of the motor is more than the required 14 years of continuous operating and 26 years of non operating lives. 4) From Fig. 4-1 of WCAP-8754 (thermal aging curve for lastic epoxy system, per IEEE Std.-275-1966) the qualified life at 120°C = 200,000 hours and from Fig. 9-1 (in which Westinghouse has drawn a most conservative projected fied insulation life of motor) the qualified life at 120°C = 96,000 hours. 5) Activation Energy: The activation energy is calculated by Arrhenius tion as follows: From Fig. 9-1 of WCAP-8754 the qualified life at 120°C = 90,000 hours and at 130°C = 45,000 hours . ---*----* ------~---*------=-----.--:--_----* --._----. . -----... : :..:--=-:- .. I * .Zrrrhenius equation where T X T X = life at a higher temperature = 45,000 hours TL = life at a lower temperature = 90,000 hours () = activation energy = to be calculated K Boltzman Constant -5 = = 8.617x10 T = higher temperature = 130 + 273 2 Tl = lower temperature = 120 + 273 Substituting in the above equation: 44,000 = 96,000 Solving: ()x(403-393) -s.167x403x393xlo-5 e () = 1.08 = 1.0 6) Calculation of Qualified Life = 403°K = 393°K i) From Fig. 9~1 of WCAP-8754 the qualified life at 120°C is 96,000 hours. This life is converted at 110°C (which is maximum operating temp of the motors per Westinghouse letter no. VPU(RRU)-48 dated Jan. 9, 1981) by using Arrhenius extrapolations: Arrhenius equation Q_ (T 2-T 1) K T 1 xT 2 T = TL e X where T = 96,000 hours X TL = to be calculated T2 = 120°c + 273 = 393°K Tl = 110°c + 273 -383°K 0 = 1. 0

I . ----.. --. ----Substituting the values 96,000 = TL e Solving: 1.0 X (393-383) 8.617xlo-jx3-3x383 TL= 207,542 hours= 23.69 years Conclusions Hence the qualified life of the motor at 110°C is 23.69 years. Out of this the motor is reg*uired to run continuously for 14 years. For conservatism let us assume that it operated continuously for 20 years at 110°C. ii) Now in the following calculations it is shown that the life of 3.69 years (23.69 -20) at 110°C is much more severe than the required 20 years of non operating life at plant ambient temp. of 40°C. T = 3.69 years= 32324 hours X TL= to be calculated T 2 = 110°C + 273 = 383°K Tl= 40°C + 273 = 313°K Substituting in the Arrhenius equation 32324 Solving 1.0 X (383-313)

-8.617x383x313xlQ-5 = TL e TL = 3235 years > 20 years Hence from the above calculations it is concluded that the subject motor is qualified for 40 years of life for the required plant service conditions . --.. **------****--*--*-- --~-----.~ ....... - / ~-------*--* -... ------------**-* -------. ----*------**--*-*---*****- --* *--: :..--Westinghouse -~-{~i -Thermal2s1rc Epor-,. ins:;latron is the ard on all larQe a: ma:h1nes. 7.C*)J vol:s a:i::l below. bu:lt a: hs!

VALVE OPERATORS FOR CONTROL AND RELAY ROOM CHILLED WATER Manufacturer,- Model: Limitorque SMB-000 Tag No(s) .: MOV-PG-107A,B, and C Worksheet No(s) .: 6-84, 85, and 86 QDR No.: 5437-66-01 Location: SB-9B DISCREPANCY The peak accident temperature exceeds the qualified peak temperature, as defined on the worksheets. RESPONSE The equipment in this item should be assigned to TER Category IIIa, Equipment Exempt from Qualification, because alternate backup equipment not affected by a Surry 2 Turbine Building HELB can cool the control room. The following statement, from section 7.4.2 of the Rev. 4 90-day response, 1s applicable: The control room habitability equipment located in Unit No. 1 Service Building Machinery room can provide the function. This can be lished by opening manual.cross-connect valves in the chilled water supply and return headers. These valves are located in the cable spreading area and are accessible from the control room without being exposed to the turbine building environment. Further discussion of this item is attached.

ATTACHMENT FOR SURRY 2 ITEM 72 VALVE OPERATORS FOR CONTROL AND RELAY ROOM CHILLED WATER The Rev. 3 worksheets (dated February 1, 1981) for these operators state that "we are presently determining what the pressure and temperature wi.11 be. resulting from a postulated Unit 2 Turbine Building HELB." The worksheets also provided essentially the_ same description of _backup equipi:nent bility that is included in the Rev. 4 (August, 1982) sions section. Even though the backup equipment is available, the intent was to_qualify the operators if possible.

After submittal of the 90-day _Rev. 3 response,.the pipe break calculation for the room containing these valve operators was completed, yielding the 310°F temperature for the first 30 minutes shown in the Rev. 4 worksheets. This temperature is clearly above the qualification limits for Limitorque SMB-000 operators. The Errata sheet for Section 7 of the REv. 4 90-day response deleted these operators from the list of control room habitability equipment for which satisfactory backup equipment is available. We have re~reviewed this concern and.conclude

that in fact the discussion of backup equipment availability does apply to these ~alve operators.

Accordingly they are exempt from qualification and will be deleted from the Master List . 30 DAY RESPONSE TO SER & TER ELECTRICAL EQUIPMENT ENVIRONMENTAL QUALIFICATION SURRY 2 COMPONENT TER Item No.: 73 TER Category: II~
