EQUIPMENT QUALIFICATION 3 RANCH FOR PORTLAND GENERAL ELECTRIC COMPANY TROJAN NUCLEAR PLANT 00CKET NO. 50-344 ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ' ELECTRICAL EQUIFMENT 1 ' INTRODUCTION l General Design Criteria 1 and 4 specify that safety-related electrical eauip-
. ment in nuclear facilities must be cacaole of performing its safety-related function under environmental conditions associated with all normal, abnormal, and accident plant operation. In order to ensure compliance with the cri-teria' the NRC staff required all licensees of coerating reactors to .suomit a reevaluation-of the qualification of safety-related electrical equipment wnich may be exposed to a harsn environment.
2 BACKCRCLhD On ' February 8,1979, the NRC Office of Inspeccion ana Enforcement (IE) issued' to all licensees of coerating plants (excect those included in the systematic evaluation program (SEP)) IE Bulletin IES 79-01, " Environmental Qualification of Class IE Equipment." This bulletin, together with IE Circular 78-08 (issued on May 31, 1978), required the licensees ~to perform reviews to assess '
the adequacy of their environmental qualification programs.
Suosequently, Commission Memorandum and Order CLI-80-21 (issued on s!ay 23, 1980) states.tnat the 00R guidelines and portions s' NUREG-0588 (wnica were issued on January 14, 1980, as enclosures a anc 5 ta IE3-79-013) form the requirements' that licensees must meet regarding environmental qualification of
. safety-related electrical equipment in order to satisfy those asoects of 10 CFR 50, Appendix A, General Oesign Criterion (GDC)-4 This order 2150 requires the staff to complete safety evaluatics reports (5ERs) for til ocarating plants by February 1, 1981. In addition, this order requires that tne licensees have qualified safety'related equipment installed in their plants oy, June 30, 1982.
Sucolaments to IES79-013 were issued for further clarification ano def'nition of. the. staf f's needs. 7hese supolements were issued on Feoruary 29, Sectemoer 30, and October 24, 1980.
In addition, the staff issued orders datec August 29,1980 (amenced in September 1930) and Octooer 24, 1980 to all licensees. The August order required that tne licensees crovide a recort, by Novemce- 1, 1980, documenting the qualification of safety-related electrical equipment. The October order requirea tne estaolishment of a central file loca-icn for the maintenance 1of all equipment qualification records. The central file was mandated to Os-estaolisned by Cecemoer 1, 1980. 7ae order also required that all safety-related electrical ecuipment ce qualifisc cy June 30, 1982. In 1

response, the licensee submitted information througr letters dated March 7, April 25, May 19, and September 5,1980 and January 13, 1981.
2.1 Purcose.
The purpose of this SER is to identify equipment whose qualification program does not provide sufficient assurance that the equioment is _cacable of performing the design function in hostile environments. The staff position relating to any identified deficiencies is provided in this report.
2.2 Scoce i The scope.of this recort is limited to an evaluation of the equipment wnich must function in order to mitigate tne consequences ,of a loss-of-coolant
, accident (LOCA) or a high-energy-line-break (HEL3) accicent, inside or outside containment, .hile subjected to the hostile environments associated with these accidents.
1' 3 STAFF EVALUATION The staff evaluation of tne licensee's response. included an onsite inspection of selected Class IE equipment and an examination of the licensee's report for completeness and acceptaoility. The criteria described in the 00R guidelines and in NUREG-0$88, in part, were used as a basis for the staf f evaluation of the acequacy of the licensee's qualification program, 5
The NRC Office of Inspection and Enforcement performed (1) a preliminary -
evaluation of tne licensee's response, documented in a tecnnical evaluation recort (TER) and (2) an onsite verification inspection (Acril 15-13 and
-Octooer 27-31, 1980) of selected safety-related electrical ecuipment. The safety injection system was insoected.- The inscection verified procer installation of equipment, overall interface integrity, and manufacturers' nameolate data. The manufacturer's name'anc model numoer from tne nameolate dats were C0mpared to information given in the C0mponent Evaluation Work Sheets (CES) of tne licensee's report. The first and second site inspections are documented in recorts IE 50-344/80-08 and 324/30-27, respectively. No deficiencies were noted. For this review, the documents referenced acove have been factored into the overall staff evaluation. ,
3.1 Comoleteness of Safety-Related Ecuie.nent In accordance witn IE3 79-013, tne licensee das directad to (1) estaotisn a list of systems and scufoment that are required to mitigate a LCCA anc an HEL3 and (2) identify comoonents_ neecec to perform tne function of safety-relatec display information, post-accicent samoling and monitoring, anc raciation monitoring.
The staff develooed a generic master list tased upon a review of piant safety analyses and emergency procedures. The instrumentation selected incluces o,arameters to tonitor overall plant performance as . ell as to monitor One :er-tormance of the systems on the list. The systems list was estaoiisned On the casis of tne functions that must be ;erformec for accident mitigation (without
. regard to location of equipment relative to nostile environments).
2
- i )- .
The list of. safety-related systems provided by the licensee was reviewed against the staff-developed master list. '
Based on 'the licensee's submittal, the staff has concluded that the information on safety-related systems included in the submittal is insufficient to verify
, that those systems are all the systems required to achieve or succort: (1) emergency reactor shutdown, (2) containment isolation, (3) reactor core coo'ing, (4) containment heat removal, (5) care residual heat removal, and (5) prevertion of significant release of radioactive material to the environment. The stard
- tacknowledges the licensee's-ef fort to include only those safety-related systems' located in a potentially harsh environment. However, this review escaires the listing of all safety-related systems, both-inside and outside potentiaity harsh environments. .The list of safety-related systems submitted by the licensee is included in Appendix-0, 1
Otsplay . instrumentation which provides information for the reactor coerators to aid them in the safe nandling of the plant was not specifica1!y identif'ad by the ifcensee. A comolete list of all display instrumentation mentioned 'n the LOCA and HEL3 emergency' procedures must be provided. Equipment cuali"-
cation information in the form of ' summary sheets should be provided for all components ofLthe disolay instrumentation exposed to harsh-environments.
Instrumentation wnich is not considered to be safety related but which is
- mentioned in the emergency procedure should acpear on the list. For these instruments,-(1) fustification should be provicea for not considering the instrument safety related and (2) assurance should be~provided that its subsequent failure will not mislead the operator or adversely af fect tne . r mitigation of the consequences'of the accident. The environmental qualifi-cation of post-accident samoling and monitoring and raciation monitoring ecuipment is closely related to the review of the TMI Lessons-Learned mocif'ca-tions and will be performed in conjunction witn tnat review. -
The licensee identified 416 items of equipment whien were assessed by .tne staff.
- 3. 2 Se'rvice Conditions 1
Commission Memorandum and Orcer CLI-80-21 requires that the 00R guicelines and the "For Comment" NUREG-0588 are to ce used as the criteria for establishing the adequacy of the safety-related electrical equipment envirormentil quali-fication program. These documents provide the cotion of estaolishing a counoing cressure and temperature condition based on clant-scecific analysis identif'sc in the licensee's Final Safety Analysis Recort (FSAR) or based on generic profiles using tne metnocs identified in nese documents.
On this basis, the staff nas assumed, unless otherwise noted, that the ana!ysis i - Ifor developing the environmental envelopes, relative to tne temoerature, pressure, and the containment spray caustics, has been performed in accorcance uita tne requirements stated aoove. The staf f nas revieweo the qualification documenta-
. tion to ensure tnat the qualification specifications envelope the conoitions
-, estaolisned by the licensee. During this review,. the staf f assumed that for
?
plants designed and equipped with an automatic containment spray system onica satisfies tne single-f ailure criterion, the main-steam-line-creak (MSL3) 3 i
-,,m,...---,..+-..-wwerm,-e99%.,,,-n,y-pv.+.,eg.,ery.--ew,,9.,.,cv-,,,,.,,y-%-,--,,-,,-* %,-e e- w w ,-., ww.e-. r we w , . .e...ww--<=,--..e.-.e....-e+--*-**
s ,
environmental conditions are enveloped by the large-break-LOCA environmental conditions. The staff assumed, and requires the licensee to verify, that the containment spray system is not subjected to a disabling single component failure and therefore satisfies the requirements of Section 4.2.1 of the 00R guidelines.
Equipment submergence has also bean addressed where the possibility exists that flooding of equipment may result from HEL3s.
3.3 Temoerature. Pressure, and Humidity Conditions *nside Containment The licensee nas pecvided the results of accident analyses as follows:
Max Temo (*F) Max Press (osig) Humidity (0 uGCA 296 50 100 MSLB not proviced not provided 100 The staff has concluded tnat the ninimum temoerature profile used in the specifications for equicment qualification purposes snould include a margin to account for higner-than-average temperatures in tne upcer regions of the ,
containment that can exist due to stratification, escecially following a postulated MSL3. Use of tne steam saturation temperature corresponding to the total building pressure (partial pressure of steam plus partial pressure of air) versus time will provide an acceptacle margin for eitner a costulated LOCA or MSL3, wnicnever is controlling, as to potential adverse environmental effects on eqai: ment.
The licensee's scecified temcerature (service condition) of 236* coes not satisfy One acove recuirement. A saturation temcerature car esconding to the grassure profile (307*F peak temcerature at 50 psig) snould e used instead.
The licensae should update his ecuipment summary taoles to reflect tais :nange.
If there is any equipment tna; coes not meet the staf f position, ne licensee must provide either justification that the equicment will :erform its intanced function uncer the specified conditions or propose corrective action.
3.4 Temeerature. 3ressure, and Humidity Conditions Gutside Containment The licensee has provided the temoerature, pressure, and numidity associated with an HEL3 autside containment, as 4 ell as acclicacia radiation levels asso-ciated with equipment in :ne aroximity of recirculatirg fluid lines. The following areas outsice containment nave een addressac:
(1) Auxiliary building (2) Main stea:n succort structure between tur:ine and containment building (3) Outsice area :etween containment ouilding and main steam succort structure (a) Picing senetration area between fuel cui' ding, contairment cuilding, and auxiliary cuilding.
The staff nas serified that tne carameters identified by tne licensee for the MSL3 are scceptacle.

1 3.5 Sucmergence !
The maximum submergence levels have been established and assessed by tne )
licensee. Unless otherwi.e noted, the staff assumed for this review tnat the '
methocology employed by the licensee is in accordance with the aaprocriate l criteria as established by Commission Memorandum and Order CLI-80-21. I The licensee stated that all equipment required for post-LCCA/MSL3 long-term I coerat :n cas either been relocated above flood level, or replaced by equicment i
quali'iad for submergence, or is scheduled for replacement by squioment qualified for suo argence. However, the licensee's value was not reported 'a his sucmit-tals. :n view of tne fact that maximum flood level inside containment cannot be es a:lished by One review of licensee submittals, submergen 3 will be consice ed as an open item for this evaluation. Comoonents naving the potsntial to ce .suomerged can be exemot from submergence qualification if tne licensee can pro,ide an assessment of the failure moces associated with these components.
The licansee should also provice assurance that the subsequent f ailure of :nis comoonent will not adversely affec*. any other safety functions or misle 1 an coerator. Additionally, tne licensee snould discuss coerating time, across the scec: rum of events, in relation to the time of submergence. If One resul s of the licensee's assessment are acceptacle, tnen these comoonents may be exemot from tne suomergence parameter of qualification.
It is not clear from the information submitted tnat suomergence of safety-related electrical equipment outside of containment was addressed. The licensee should address this 3rea more specifically in the 30-day response arld upgrade the CE5 as accropriate.
- 3.6 Chemical soray The licensee's FSAR value for the enemical concentration is not mentioned in nis suomittals; however, the pH value quoted in ne TER for spray inside containment is 4.9-10.0. Therefore, for the purpose of tnis review, One effects of cnemical spray will be ccnsicered unresolved. The staff will review the licensee's response snen it is suomitted anc discuss tne resolution in a supplemental report.
- 3. ? Acing Section 7 of the 00R guidelines does not require a cualified life to be estab-lisned 'or all safety ' .ated electrical equipment. However, the following actions are requirec:
(1) Ma<e a cetailed comoarison of existing equicment and .ne materials icenti-fied in Apoent / C of the 00R guidelines. The first supplement to IE3-79-013 requires licensees to utilize the table in Accencix C and icentify any aca;tional materials as tne result of neir af' ort.
(2) Establisn an ongoing program to review surveillance anc maint1 nance records to icentify potential age-related cegradations.
(3) Estaclish comoonent maintenance and reolacement scnedules anicn include considerations of aging cnaracter'stics of the installed components.
5
., ' 4 The licensee identified a numoer of equipment items for which a specified qualified life was established (for examole, 5 years,15 years, or 40 years).
In its assessment of these submittals, the staff did not review the adequacy of the methodology cor the basis used to arrive at these values; the staff has 1 assumed that the established values sre based on state-of-the-art technology l and are acceptable.
1 For this review, however, the staff requires that the licensee submit supple-mental information to verify and identify tne degree of conformance to the above requirements. The response should include all tne equipment identified
~as required to maintain functional operability in harsh environments.
l^ The licensee indicated that this pnase of the response is outstancing and hat the review is in prtgress. The staff will review the licensee's resconse unen it is submitted and discuss its evaluation in a suoplemental recort.
3.8 Radiation (Inside and Outside Containment)
The licensee has provided values for the radiation levels postulated to exist I following a LOCA. The application anc :nethodology employed to determine these values were presented to the licensee as part of the NRC staff criteria con-tained in tne 00R guideilnes, in NUREG-0588, and in tne guidance provided in IES-79-018, Suopic Int 2, Therefore, for this review, the staff has assumed that, unless-otherwise noted, the values provided nave bean determinec in accordance with the prescribed criteria. The staff review determined that the i
values to wnich equipment was qualified enveloped the requirements identified by the licensee.
The 'value required by the licensee indice containment is an integrated dose'of
- 2. 2 x 107 rads These values do not envelope the 00R guiceline requirements and therefore are not acceptat 4. Tne radiation service condition proviced oy the licensee is lower than provided in tne guidelines for gamma ana beta radiation. The licensee is recasted to eitner provice justification for using the lower service conditicq or use tne guidelines for octn gamma and ceta raciation. If the former option is cnosen, then the analysis--including tne basis, assumptions, anc a sample calculation--should te provided.
A required value outside containment of 2.1 x 107 rads has been used by the
- licensee to specify limiting radiation levels in areas containing re' circulating reactor ceolant in tne auxiliary Duilding. This value apcears to consider the radiation levels influenced by the source term methocology associated with post-LOCA recirculation fluid lines, and
- s therefore accactacle.
1 4 QUALIF! CATION OF EQUIPMENT The following subsections present tne staff's assessment, casec on tne ifcensee's i
suomittal, of tne cualification status of safety-relatec electrical equioment.
The staff has separated the safety-r, n.1 equipment into tnree categories:
(1) equipment requiring immediate corre nive action, (2) ecujoment reoufring additional .ualification information and/or correc ive action, and (3) equio-ment consi .erea acceptsole if One staff's concern identifiac in 5ection 3.7 is i satisfac urily resolvad.

1 l
In its assessment of the licensee's submittal, the NRC staff Gio not review l the methodology employed to determine the values established by the licensee. !
However, in reviewing the data sheets, the staff made a determiration as to the stated conditions presented by the licensee. Additionally, .he staff has not completed its review of supoorting documentation referenced oy the licen-see (for example, test reports). It is expected that wnen the review of test recorts is complete, the environmental qualification data bank estaclished by the staff will provide the means to cross reference each suctu ting document !
to the referencing !icensee. I
'f supporting documents are found to ce unacceptable, the licarsee will De required to take additional corrective actions to eitner estro::sh qualifi-cation or replace the item (s) of concern. This effort will eg"n in early l 1981.
! An appendix for each subsection of this report provides a list ol' equipment for which additiona', information and/or corrective action is required. 'dhe re l
{
accropriate, a reference is provided in the appendices to icentify deficiencies. l It snould be noted, as in the Commission Memorandum and Orcer, . at the deficien- l cies identified do not necessarily mean that ecuipment is uncuaiified. However, they are c?use 'or concern and may require further case-by-case avaluation.
4.1 Eouiement Recuirino Immediate Corrective Action l
Appendix A identifies equipment (if any) in this category. The licensee was asked to review the facility's safety-related electrical ecuiccent. The l
[
licensee's review of this equipment, in accordance witn.One recuirements of IES79-013, has identified several types of. equi ment 'see Apoencix A) wnere reasonaole assurance does not exist tnat the equi; ment will not fail when it is excosed to the environmental canaitions postulated in IE3 79-013. There-fore, a licensee event report (LER 30-22) was sucmitted by tne licensee to the NRC on October 31, 1980. The 1icensee stated tnat tne occurrence was l caused by changes in tne criteria f' anvi ronmen t!.i ;ualification of safety-l related electrical equipment from .jan FSAR to those recuired oy IE3 79-013,
! and nas no effect on eitner plant puolic safety. The immediate corrective action taken by the licensee was to perform a safety evaluation to ensure that Muipment failure would not preclude the performance of safety- elated functions, c; documented in Enclosure a of the licensee's suomittal of Sectemcer 9,1980.
I loe permanent corrective action taken will be replacement or acaif f fation of ecuipment to meet tne qualification criteria of IES79-013 cefore June 30, 1982. In acdit on, the staff has not identi fied any safety-related electrical d
ecuicment =hicn is not sole to perdarm its intenced safety func. ion curing the time in snica it must operate.
4.2 Ecuicment Recuirino Adaitional Information anc/or Correct ive Action Accendix 3 identifies ecuipment in this category, inclucing a taculati:n of f deficiencies. The deficiencies are noted by a letter relating to tne legena I (icentified celow), indicating that the information proviced is not suf ficient for tne qualification parameter or condition.

QI qualification information being developed l RPS - equipment relocation or replacement schedule provided As noted in Section 4, .these deficiencies do not necessarily mean that the equipment is unqualified. However, the deficiencies are cause for concern and require further case-by-case evaluation. The staff has determined that an acceptable o' asis to exempt equipment from qualification, in whole or part can
.be established provided the following can be established and verified by tne l i.censee:
-(1) Equipment does not perform essential safety functions 'in the harsh environ-ment, and equipment f ailure in the harsn environment will not imoact t safetyrrelated functions or mislead an operator.
1 0- (2a) Ecufpment performs its function before its exposure to the harsn enviror-( . ment, and tne adequacy for the time margin proviced is adecuately justi"ed, and (2b) Subsiquent failure of the equioment as a result of the harsh environment i coes not degrace other safety functions or mislead the operator.
l (3) The safety-related functirn can be accomplished by some other designated equipment that nas oeen adequately qualified and satisfies tne single-failure critarion.
I (4) Equipment will not be sucjected to a narsn environment as a result of tne costulated. accident.
'The licensee is, therefore, required to supotement the information presented by providing resolutions to the deficiencies icentified; these resolutions
'snould incluce a description of the corrective action, senedules for its K completion (as apolicaole), and so fortn. The staff will review :ne licensee's fj -
response, when it is submitted, and discuss the resolution ir, a sucolemental
' report.
3
It should be noted that in cases where testing is being conducted, a condition may arise which results in a determination by the licensee that the equipment does not satisfy the qualification test requirements. For tnat equipment, the licensee will be required to provide the proposed corrective action, on a timely basis, to ensure that qualification can be established by June 30, 1982.
4.3 Ecuioment Considered Acceatable or Conditionally Accectacle Based on the staff review of the licensee's submittal, the staff identified the equipment in Appendix C as (1) acceptable on the basis that the qualif f-cation program adequately enveloped the specific environmental plant parameters, or (2) conditionally acceptacle subject to the satisf actory resolution of the staff concern icentified in Section 3.7.
For the equipment identified as conditionally acceptacle, tne staff determineo that the licensee did not clearly (1) state that an equipment material evaluation was conductec to ensure that no known materials susceptible to degradation because of aging nave been used, (2) establish an ongoing program to review the plant surveillance and main-tenance records in order to identify equioment degradation wnica may be age related, and/or (3) cropose a maintenance program and reolacement schedule for equioment ,
identified in item 1 or equipment that is qualified for less taan the life of tne plant.
The licensee is, therefore, required to sucplement the information presentec for equipment in :nis category before full acceptance of tnis equioment can ce establisned. The staff will review the licensee's rescansa wnen it is suo-mitteo ar.d discuss the resolution in a supplemental report.
5 DEFERRED REQUIREMENTS IES79-018, Suoplement 3 has relaxed the time constraints for the sucmission of the information associated with cold shutdown ecuioment and TMI lessons-learned modifications. The staff nas required tnat tnis information ce provided by Feoruary 1,1981. The staff will provice a sucolemental safety evaluation addressing these concerns.
5 CONCLU$ IONS The staf f nas cetermined that tne licensee's listing of safety'-related systems ano associated electrical souioment wnose acility to function in a narsh environment following an accident is recuired to mitigate a LCCA or HEL3 is comolete and acceptacle, except as notea in Section 3 af this recort. The staff nas also determinec tnat the environmental service conditions to ce met by the electrical ecuipment in the narsh accident environment are aporopriate, 9
t except as noted in Section 3 of this report. Outstanding information identified in Section 3 should be provided within 90 days of receipt of this SER.
The staff has reviewed the qualification of safety-related electrical equip-ment to the extent defined by this SER and has found no outstanding items which would require immediate corrective action to ensure the safety of plant operation. However, the staff has determined that many items of safety-related electrical equipment identified by the licensee for tnis review do not have adequate documentation to ensure tnat they are capaole of withstanding the harsh environmental service conditions. This review was based on a comparison
.of the qualification values with tne specified environmental values required '
by the design, wnich were provided in the licensee's summary sheets.
.5ubsection 4.2 identified deficiencies tnat must be resolved to estaolf sn the qualification of the equipment; the staff requires that the information lack-ing in this category be provided within 90 days of receipt of tnis SER.
Within this period, the licensee should either provide documentari of the missing qualification information which demonstrates that such eq '
meets the 00R guidelines or NUREG-0588 or commit to a corrective action , qualiff-cation, replacement, relocation, and so forth) consistent with the r9euirements to establish qualification oy June 30, 1982. If the latter option is cnosen, the licensee must provide justification for operation until sucn corrective action is complete.
Subsection 4.3 identified acceptance and conditional acceptance based on noted i deficiencies. Where additional information is required, the licensee should respond within 90 days of receipt of this SER by providing assurance that
. these concerns will be utisfactorily resolved by June 30, 1982.
The staff issued to tne licensee Section 3 and 4 of this report and requested, under the provisions of 10 CFR 50.54(f), tnat tne licensee review tne ceficien-cies enumerated and one ramifications thereof to determine snether safe coeration of the facility would ce impacted in consideration of the deficiencies. The licensee has completed a preliminary review of tne idantified ceficiencies and has determined that, after due consideration of tne deficiencies and their ramifMations, continuec safe operation would not be adversely affected.
Sased on these considerations, the staff concluces that conformance with tne above requirements and satisfactory completion of the corrective ac. ions by June 30, 1982 will ensure ct:apitance with the Commission Memorandum ana Order of May 23,1980. The stsff furtner concludes . hat there is reasonaale assurance of continued safe operation of this facility pencing comoletion of
- these corrective actions. This conclusion is based on the following:
(1) that tnere are no outstanding items wnich aculd require immeciate correc-tive action to assure safety of plant operation (2) some of the items found deficient have oeen or are being replacec or relocated, thus improving the facility's caoacility to function " allowing a LOCA or HEL3 10

Subject:
Potential Deficiency Affecting Foxboro Transmitters, Model Numbers N-Ell, N-E13 or Ell, E13 with suf fix Codes /MCA, /MCA/RRW, or /MCA/RR Gentlemen:
Our records indicate that you have received one or more of the Foxboro model nu=bered transmitters listed above. This letter is to notify you that two deficiencies have been discovered in some of these transmitters which may exist in the units shipped to you. The transmitters in question operate at a signal level of 10-50mA. Similar modc: numbered units operating at 4-20mA are not affected.
The first issue involves the possible use of incorrect insulating sleeving on transistor and zener diode lead wires in the amplifier. The second issue involves the use of a specific vendor's capacitor which is not hermetically sealed (although claimed to be so). As a result, the capacitor electrolyte can leak under adverse service conditions, specifically heat and time. The failure mode is a decrease in resistance across the capacitor resulting in electrical leakage. The transmitter operation can be affected by limiting the output to something less than full value which, in time, can degrade to no output at all.
Insulating Sleeving - Radiation resistant sleeving consisting of a silicone coated glass fiber braid has been substituted by a teflon sleeving in some transmitters. Tests have shown that teflon vill become brittle and deteriorate with a substantial integrated radiation dose. Foxboro testing has demonstrated that the teflon sleeving used in these devices will vithstand an integrated dose of 10 megarads with no noticeable deterioration. Tests to 200 megarads produce the brittle conditions which can result in the teflon flaking from the wires.
Based on these tests, operating plants not expected to exceed an integrated dose of 10 megarads have no potential problem and no action is required.
1 Where the integrated dose rate could exceed 10 megarads, then units in service should be inspected to deter =ine if the proper insulating materini has been used. This can be accomplished by opening the transmitter in accord: ace with l Foxboro }bster Instruction MI 20-145. The amplifier cover must be removed
[
exposing the a=plifier assembly. .At one end of the assembly, a transistor and a zener diode are mounted in the' base casting which serves as a heat sink. The insulating material in question is a sleeving slipped over the lead sites from these two co=ponents. The proper material is white and heavy looking. Positive l'OXBORQ M

Subject:
identification can be made by inspecting one end of the material to establish that the outer material covers an inner braid. Teflon, if used, will be a single layer material and could be either clear or white.
If improper insulation is present, then the corrective action is to replace the-a=plifier (Foxboro P/N N0148PW) . Replacement amplifiers can be purchased from you. local Foxboro Sales or Service Representatives. If you prefer to have Foxboro Service Personnel inspect the equipment and, if necessary, replace the a=plifier, this can be arranged at standard service rates.
Capacitor - The capacitor degradation problem was discovered over time thr'ough tracking f ailure situations. Internal corrective action has been taken to remove the vendor involved from the qualified vendor list and to purge all stock
'of capacitors from this vendor. Degradation of this capacitor is a function of time and service conditions with heat being a primary contributor. This phenomenon was observed in recent tests of transmitters using these capacitors. The capacitor in question is manuf actured by Cornell-Duebilier and can be specifically identified by a type number in the form TX-65-XXXX as well as a monogram in a box followed by a *date code, e.g. l CDZ 0874 l . It is assigned Foxboro part number N0141MF.
To determine if this capacitor is present requires a visual inspection of the
' amplifier which can be accomplished as described above for the insulating sleeving inspection. The recoc= ended corrective action should the above described capaciter be present is to replace the amplifier (Foxboro P/N N0148PW) although is is possible to replace the capacitor with a Foxboro provided substitute. Use of Foxboro Service personnel to perform the inspection and replacement, if necessary, can be arranged at standard service rates as described above.
Due to lack of knowledge of specific application, redundancy, and the like, Foxboro cannot determine if the NRC reporting requirements of 10CFR Part 21 a;e applicable.
This determination is the responsibility of the user and any such reporting would be made by them af ter completing their evaluation of the situation.
If you have any questions regarding the above, please contact the undersigned directly.
