l SAFETY EVALUATION REPORT SY THE OFFICE OF NUCLEAR REACTOR REGULATION EQUIPMENT QUALIFICATION BRANCH FOR MAINE YANKEE ATOMIC POWER COMPANY 00CKET NO. 50-309 ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT 1 INTRODUCTION General Design Criteria 1 and 4 specify that safety-related electrical equip-ment in nuclear facilities must be capable 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 if censees of operating reactors to submit a reevaluation of the qualification of safety-related electrical equipmert wnicn may be exposed to a harsh environment.

2 BACKGROUND On February 8,1979, the NRC Office of Inspection and Enforcement (IE) issued to all licensees of operating plants (excaot 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 (issueo on May 31, 1978),* required the licensees to perform reviews to assess the - -

adequacy of tneir environmental qualification programs.

Subsequently, Commission Memorandum and Order CLI-80-21 (issued on May 23, 1980) states that the 00R guidelines and portions of NUREG-0538 (wnich were issuad on January 14, 1980, as enclosures 4 and 5 to IES-79-013) form the requirements that licensees must meet regarding environmental qualification of safety-related electrical equipment in order to satisfy those aspects of 10 CFR 50, Appendix A, General Design Criterion (GOC)-4 This order also requires the staff to complete safety evaluation reports (SERs) for all operating plants by February 1, 1981. In addition, this order requires tnat the licensees have qualified safety-related equipmert installed in their plants by June 30, 1982. .

l Supplements to IE3 79-013 were issued for further clarification and definition l

of the staff's needs. These suoplements were issued on Feoruary 29, Sectem-i ber 30, and Octooer 24, 1980.

In addition, the staff issueo orcers dated August 29, 1980 (amended in Septem-ber 1980) and October 24,1980 to all licensees. The August order amencment recuired that the licensees provide a report, by Novemoer 1,1980, documenting tne qualification of safety-related electrical equipment. The October order required the establisnment of a central file location for the maintenance of all equipment-qualification recorcs. The central file was mandated to be establisned by Decemoer 1, 1980. The order also required that ali safety-relatec electrical equipment be qualified by June 30, 1982. In resconse, the licensee submitted information through letters dated June 15, 1979'and June 2 and Octooer 31, 1980. .

l

2.1 Purcose The purpose of this SER is to identify equipment whose qualification program does not provide sufficient assurance that the equipment is capable of performing the design function in hostile environments... The staff position relating to  :

any identified deficiencies is provided in this report.

2.2 Scoce The scope of this report is limited to an evaluation of the equipment which must function in order to mitigate the consequences of a loss-of-coolant i accident (LOCA) or a high-energy-line-break (HEL3) accident, inside or outside containment, while suojected to the hostile environments associated with these accidents.

3 STAFF EVALUATION The staff evaluation of the licensee's response included an onsite inspection i of selected Class IE equipment and an examination of the licensee's report for completeness and acceptability. The criteria described in the 00R guidelines and in NUREG-0588, in part, were used as a basis for the staff evaluation of the adequacy of the licensee's qualification program, i The NRC Office of Inspection and Enforcement performed (1) a preliminary evaluation of the licensee's response, documented in a technical evaluation report (TER) and (2) an onsite verification inspection (Septemoer 3-11, 1980) of selected safety-related electrical equipment. An inspection of equipment associated with the main steam system, high pressure safety injection system, and containment spray system was conducted during the site visit. The inspec-tion at the Maine Yankee plant verified croper installation of equipment, overall interface integrity, and manufacturers' nameplate data. The manufac-turer's name and model numoer from the nameplate data were comoared to infor-mation given in the environmental qualification ucrk sneets of the licensee's report. The site inspection is documented for the Maine Yankee plant in

, report IE 50-309/80-14 No deficiencies were noted. For this review, .ne documents referenced above nave been factored into the overall staff evaluation.

i 3.1 Comoleteness of Safety-Related Ecuicment ,

In accordance with IES79-013, the ifcensee was directed to (1) establisn a list of systems and ecuipment tnat are required to mitigate a LOCA and an HEL3 and (2) identify the most limiting environmental conditions the ecutament may be exposed to ano still be required to perform its safety function.

The staff developed a generic master list cased upon a review of Diant safety analyses and emergency procedures. The. instrumentation selected inc! aces carameters to monitor overall plant performance as well as to monitor One cer-formance of the systems on the list. The systems list was estaolished :n the basis of the functions that must ce performed for accident mitigation (without regard to location of equipment relative to hostile environments).

The list of safety-related systems provided by the licensee was reviewed against the staff-developed master list.

2

i a

Based upon information in the licensee's submittal, the' equipment location references', and in some cases subsequent conversations with the licensee, the staff has verified _and determined that.the systems included in the licensee's submittal are those required to achieve or support: (1) emergency reactor shutdown, (2) containment isolation, (3). reactor core cooling, (4) containment heat removal, (5) core . residual heat ' removal, and (6) prevention of significant release of radioactive material-to the envircnment. The staff therefore concludes that the systems identified by 'the licensee (listed In Appendix 0) are acceptable, with the exception of those items discussed in Section 5 of l

this report.

~

Display instrumentation which provides information for the reactor operators to aid them.in the safe handling of the plant was not specifically identifed i cy the licensee. A complete list.of all display instrumentation mentioned in i the LOCA and HELB emergency procedures must be provided. Equipment qualification information in the form of summary sheets snould be provided for all components  ;

of the display instrumentation exposed to harsn environments. Instrumentation which is not considered to be safety related but which is mentioned in the emergency procedure should appear on the list. For these instruments, (1) justification should be provided for not considering the instrument safety related and (21' assurance should be provided that its suosequent failure will not mislead the operator or adversely affect the mitigation of the consequences .

of the accident. The environmental qualification of post-accident samoling and monitoring and radiation monitoring equipment is closely related to the review of the TMI Lessons-Learned modifications and will be performed in conjunction with.that review. .

. The licensee identified 473 separate safety-related equipment items,193 of l- which are required to perform a safety-related function in a LOCA or a HEL3 l environment. The licensee provided a summary of the qualifica ion documen-l tation and metnodology used to qualify safety-related equipment which is i required to function in hostile environments. The remaining bulk of the j safety-related equipment was not qualified to the hostile environments on the basis that it is:

(1) required to function only in nenharsh environments, or ,

(2) not required to function for any accident, or (3) not required to function for the accident producing the harsn l' environmental conditions.

Based on its review of the information proviced by the licensee, the staff concludes that this information is incomplete. The licensee is asked to verify that f ailure of the equipment icentified in the acove categories *ould not ce detrimental to safety as a result of a harsh environment. Failures of this equipment that could lead to disabling a safety function or provice incorrect information to the operator during accident mitigation snould oe addressed. In addition, the licensee's response did not identify or provide r

qualification documentation for cable splices or connectors, instrument and terminal box sealant material, and terminal and penetration connection boxes.

The licensee is asked to provide this information or to justify examption of this equipment from qualification on some other defined basis. Also, the licenses has excluded the following safety-related equipment:

(1) pressurizer spray control valve (2) comoressed air system 3

_ _ _ . _ . _.. _ . _ _ . _ . _ . _ _ . . _ _ _ . _ . _ . _ _ _ . . _ . _ _ _ . _ . ~ ._._,_... _ ._._

e (3) PORVs (4) containment air recirculation dampers.

The staff requires that the applicant justify excluding this equipment or modify the design accordingly.

. Based on the staff review of the equipment and systems identified by the licensee and subject to the satisfactory resolution of the items identified above, the staff concludes that'the systems identified by the licensee (listed in Appendix 0) are acceptable, with the exceptions of those items discussed in Section 5 of this report.

3. 2 Service Conditions Ccamission Memorandum and Order CLI-80-21 requires that the 00R guidelines and the "For Comment" NUREG-0588 are to be used as the criteria for establisning the adequacy of the safety-related electrical equipment environmental qualiff-cation program. These documents _ provide the option of establishing a bounding

=

pressure and temperature condition based on plant-specific analysis -identified in the licensee's Final Safety Analysis Report (FSAR) or based on generic profiles using the methods identified in these documents.

On this basis, the staff has assumed, unless otherwise noted, that the analysis for developing the environmental envelopes for the Maine Yankee olant, relative to the temperature, pressure, and the containment scray caustics, has been performed in accordance with the requirements stated above. The staff has

  • reviewed the qualification documentation to ensure that the galification specifications envelope the conditions estaclished oy the licensee.

Equipment submergence has also been addressed where the possibility exists that floocing of equipment may result from HEL3s.

3.3 Temaerature, Pressure, and Humidity Conditions Inside Containment The licensee has provided the results of accident analyses as follows:

Max Temo (*F) Max press (psic) Humidity N l LOCA 278 54 100 MSL3 340 43 100 ,

The staff has concluded that the minimum temoerature profile for equipment qualification purcoses snould incluce a margin to account for nigner-than-average temperatures in the uoper regions of the containment that can exist due to stratification, especially following a postulated MSL3. Use of tne steam saturation temperature corresponcing to One total building pressure (partial '

pressure of steam plus partial pressure of air) versus time will provide an acceptacle margin for either a postulated LOCA or MSL3, wnichever is controlling, as to potential adverse environmental effects on equipment.

The licensee's specified temperature (service condition) of 278 F does not satisfy the above requirement. A saturation temperature corresconding to the peak profile (302 F peak temperature at 54 psig) should ce used instecd. The A

licensee should update lhis equipment summary tables to reflect this change.

1If there-islany equipment that does not meet the staff position, the licensee

.must: provide either justification- that the equipment will perform-its intended function under the specified conditions or propose corrective action.

3.4; Temperature, Pressure, and Humidity Conditions Outside Containment The licensee'has provided'the. temperature, pressure, humidity and= applicable environment associated with an HELS outside containment. The following areas

.outside containment have been. addressed:

(1) Primary auxiliary building _

(2)'. Auxiliary feedwater pump area (3) Spray; pump area . .

.(4): Steam and.feedwater valve area f(5) Turbine building

~ The licensee has used 205'F and amoient pressure conditions for areas outside containment. The staff considers saturation temperature at the peak pressure resulting from a HELS:as the minimum level for acceptance. The licensee should update his summary tables to reflect this change. If there is any -

equipment that does not-meet the staff position, the licensee must provide justification that the equipment will perform its intended function under saturation ~ conditions or propose corrective action.

i 3.5 Submercence The maximum submergence levels have been established and assessed by the licensee. Unless otherwise noted, the staff assumed for this review cnat the .

methodology employed by the licensee is in accorcance with the accropriate  !

criteria as establisned by Commission Memorandum and Order CLI-30-21.

l The licensee's value for maximum submergence is 1.7 ft. Equiement below this level has been identified by the licensee, along with the proposed corrective action. The licensee identified seven safety-related electrical components as having the potential for becoming submerged after a postulated event. As a corrective action, tne licensee proposes reolacing these components; in some cases, the licensee is considering relocation of the components. Based on its review of the information submittals by the licensee, tne staff cond'urs with the procosed resolution. However, because the licensee incicated, in part, that some of the above items complete their safety function before su mergence, the staff reouires that the licensee sucolement this information and prov ce i tne time margins before submergence is assumed in nis analysis 'or all tne items icentified; the licensee must also verify tnat subsequent f ailure of tnis equipment snould not be detrimental to plant safety. Equicment failure wnich would result in incorrect information being proviced to tne ocerator l should also be addressed, i

The ifcensee identified the following two items as not subjected to sucmergence testing:

Item Manufacturer Model l PAM-6 level transmitter GEMS XM-36495 i

CVCS-1 motor operator Limitorque SMB-00 3

l g- e e. 9-M-me-gs--**wy-d-w +-g---et---e,*ye- c.t--ee w-,yy-,.. -y r - yue,w , w,W ree st W tv'=g=r= e y ,+g- g to g -g rse ceum ,wrgwoyke-y,he'gemme *e psqw s u=p v gem + e-peu w g w g w we y - es y - a7 q~ -twaM+-e iM--

Based on'its review of the information submitted, the staff concludes that the

- justification for not testing the equipment is incomplete in part. The staff requires.that the licenses either verify that in the event the equipment is flooded, subsequent failure of the' equipment would not be detrimental to safety, or modify the design accordingly. The licensee's response should include an assessment of equipment failure which results in incorrect information being provided to the operator. It is not clear from the informa-tion submitted that. submergence of safety-related electrical equipment outside of containment was addressed. The ifcensee should address this area more l specifically in the 90-day response and upgrade the CES as appropriate.

!- On the condition that the open items identiffeo above are satisfactorily resolved, tne staff concludes that the applicant's response satisfies the Commission requirements identified in IES 79-01 and is acceptable. The staff will address the resolution of the items identified above in a supplement to this report.

3.6 Chemical Soray The licensee's FSAR valus for the chemical concentration is 1750 ppm boric acid solution at a pH of 9.5. During the review, the staff identified several items of equipment that were tested with caustic spray concentrations signifi-cantly less than that which may be used in the plant. The licensee is there-fore required to justify the adequacy of this design on some defined basis or modify the design accordingly. The staff will review the applicant's response when it is subm.itted and present its resolution in a supplemental report.

3.7 ' Acing .

Section 7 of the 00R guidelines does not recuire a qualified life to be estae-lished for all safety-related electrical eqJipment. However, the following actions are required:

(1) Make a detailed comparison of existing equipment and tne materials identified in Appendix C of the OrjR guidelines. The first suoplement to IES-79-013 requires licensees to titilize the table in Appendix C and identify any additional materials as the result of nef r effort.

(2) Estaolish an ongoing program to review surveillance and mainterfance records to identify potential age-related degradations.

(3) Establish component maintenanca anc replacement schecules which incluce l considerations of aging charactaristics of the installec components.

The licensee indentified a numoer o' equipment items for whien a specified qualified life was established (for example, 7.7 years, 20 years, or a0 years). In its assessment of these suomittals, the staff did not review the adequacy of the methodology nor the basis used to arrive at these values; the staff has assumed that the establisned values are based on state-of-the-art technology and are acceptable.

For this review, however, the staff requires that the licensee submit scople-mental information to identify and verify the degree of conformance to the 6

L

above requirements. The response should include all the equipment identified as required to maintain functional operability in harsh environments.

3.8 Radiation (Inside and Outside Containment)

The licensee has provided values for the radiation levels postulated to exist following a LOCA. The application and methodology employed to determine these values were presented to the ifcensee as part of the NRC staff criteria con-tained in the 00R guidelines, in NUREG-0588, and in the guidance provided in IEB-79-018, supplement 2. Therefore, for this review, the staff has assumed that, unless otherwise noted, the values provided have been determiaed in accordance with the prescribed criteria. The staff review determined that the values to which equipment was qualified enveloped the requirements identifiec cy the licensee.

The value required by the licensee inside containment is between 1.1 x 108 to 1 x 108 rads for tne integrated dose. These values do not envelope the OCR guideline requirements (4 x 107 rads) and therefore are not acceptable. The radiation service condition provided by the licensee is lower than provided in the guidelines for gamma and beta radiation. The licensee is requested to either provide justification for using the lower service condition or use the guidelines for both gamma and beta radiation. If the former option is cnosen, then the analysis, including the basis and assumptions used in the analysis and a samole calculation, snould be provided.

The licensee stated that the 'adiation r doses to equipment 10 areas wnere radioactive fluids are recirculated from inside the containment for long-term core cooling have been calculated in accordance with IES 79-01 Supplement 2 and the "For Comment" NUREG-0538. In addition, the licensee stated that because of preliminary results from recent HEL3 and heat-up studies, many areas previously believed to be nonharsh have now been determined to be harsn.

The licensee is in the crocess of reevaluating the adecuacy of the equipment qualification for tnese outside containment areas. The staff will review tne licensee's resolution when it is submitted and discuss the evaluation in a supplemental report.

4 QUALIFICATION OF EQUIPMENT The following subsections present the staff's assessment, based on the licensee's submittal, of the qualification status of safety-related electrical eauipment.

The staff has separated the safety-related equioment into three categories:

(1) equioment requiring immeaf ate corrective action, (2) equioment requiring additional cualification information and/or corrective action, and (3) scuio-ment considered acceptable if tne staff's concern icentified in Sec ion 3.7 is satisfactorily resolved.

In its assessment of the licensee's submittal, the NRC staff did not review the methodology employed to cetermine the values established by the licensee.

However, in reviewing the data sheets, the staff made a determination as to the stated conditions presented by the licensee. Additionally, the staf f has j not completed its review of succorting documentation referenced by the lican-i see (for examole, test reports). It is expected that wnen the review of test 7

i u . _

e reports is completa, the environmental qualification data bank established by the staff will provide the means to cross reference each supporting document to the referencing licensee.

If' supporting documents are found to be unacceptable, the. licensee will be required to take additional corrective actions to either establish qualifi-cation or' aplace tne item (s) of concern. This effort will begin in early 1981.

An appet. x for each subsection of this report provides a list of equipment for which additional information and/or corrective action is required. Where appropriate, a reference is provided in the appendices to identify deficiencies.

It should be notac, as in the Commission Memorandum and Order, that the deficien-cies identified ca not necessarily mean that equipment is unqualified. However, they are cause for concern and may require further case-by-case evaluation.

4.1 Equicment Recuiring Immediate Corrective Action Appendix A identi#fes equipment (if any) in this category. The ifcensee was asked to review tne facility's safety-related electrical equipment. The

- licencee's review of this ecuipment has not identified any equipment requiring immediate corrective action; therefore, no licensee event reports (LERs) were suomitted. In addition, in this review, the staff has not identifiec any safety-related electrical equipment which is not aole to perform its intended safety function during the time in which it must operate.

4.2 Ecuicment Recuirina Additional Information and/or Corrective Action Appendix 8 identifies equipment in this category, including a tabulation of deficiencies. The deficiencies are noted by a letter relating to the legena (identified below), indicating that tne information provided is not sufficient for the qualification parameter or condition.

Legend R - radiation T - temperature QT qualification time RT - required time P pressure H - humidity CS - cnemical spray A - material-aging evaluation; reolacement scnedule; ongoing eouioment surveillance S - submergence '

l t

,~

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 basis to exempt equipment from qualification, in whole or part, can  !

be established provided the following can be established and verified by the licensee: ,,

(1) Equipment does not perform essential safety functions in the harsh envi-ronment, and equipment failure in the harsh environment will not impact safety-related functions or mislead an operator.

(2a) Equipment performs its function bOore its exposure to the harsh environ-ment, and the adequacy for the time margin provided is adequately justified, and (2b) Subsecuent failure of the equipment as a result of the harsh environment does not degrade other safety functions or mislead the operator.

(3)' The safety-related function can be accomolished by some other designated equipment that has been adequately qualified and satisfies the single- i failure criterion.  !

(4) Equipment will not be subjected to a harsh _ environment as a result of the '

postulated accident.

The licensee is, therefore, required to supplement the information presented by providing resolutions to the deficiencies identified; these resolutions -I should include a description of the corrective' action, schedules for its .

completion (as applicaole), and so forth. The staff will review the licensee's resconse, wnen it is submittad, and discuss the resolution in a supplemental raport.

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 that 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 Accactable or Conditionally Acceotable i

Based on the staff review of the licensee's sucmittai, the staff identifiec the equipment in Acpendix C as (1) acceptable on the casts tnat tne tuali'i- i'

ation program adequately enveloced the specific environmental clant parameters, or (2) conditionally acceptacle subject to the satisfactory resolution of the staff concern, identified in Section 3.7.

For the equipment identified as conditionally acceptable, the staff determinec that-the licensee did not clearly:

(1) state that an equipment material evaluation was conducted to ensure that no known materials susceptible to degradation because of aging have been used, 9

l l

(2) establish an ongoing program to review the plant surveillance and main-tenance records in order to identify equipment degradation which may be age related, and/or (3) propose a maintenance program and replacement schedule for equipment identified in item 1 or equipment that is qualified for less than the life of the plant.

The licensee is, therefore, required to supplement the information presented for equipment in this category before full acceptance of this equipment can be estaolished.. The staff will review the licensee's response wnen it is suo-mitted and discuss the resolution in a supplemental report.

5 DEFERRED REQUIREMENTS  :

IES79-018, Supplement 3 has relaxed the time constraints for the suomission of the information associated with cold shutdown equipment and TMI lessons-learned modifications. The staff has required that tnis information be orovided by Feoruary 1, 1981. The staff will provide a supplemental safety evaluation addressing these concerns.

6 CONCLUSIONS The staff has determined that the licensee's listing of safety-related systems and associ.ated electrical equipment whose acility to function in a harsn environment following an accident is recuired to mitigate a LOCA or HEL3 is complete and acceptable, except as noted.in Section 3 of this report. The

. staff has also determined that the environmental service conditions to be met by the electrical ecuipment in the harsh accident environment are approcriate, except as noted in Section 3 of tnis recort. Outstanding information identified in Section 3 should be proviced sithin 30 days of receipt of this SER.

The staff has reviewed the qualification of safety-related electrical ecuipment to the extent defined by this SER and has found no outstanding items wnich would require immediate corrective action to ensure the safety of plant opera-tion. However, the staff has determined that many items of safety-related electrical equipment identified by the licensee for this review do not have adequate documentation to ensure that they are capable of withstanding the harsh environmental service conditions. This review was based on a" comparison of the qualification values with the specified environmental values required by the design, which were provided in the licensee's summary sheets.

Suosection 4.2 identified deficiencies that must be resolved to establisn the qualification of.the equipment; the staff requires that the information lacxing in this category be proviced within 90 days of receiot of this SER. Within this period, the' licensee snould either provice documentation of tne nissing cualification information which demonstrates that such equipment meets the CCR guidelines or NUREG-0588 or commit to a correc .ive action (requalification, replacement, relocation, and so forth) consistent witn tne requirements *.o establish qualification of June 30, 1982. If the latter option is chosen, the licensee must provide justification for operation until such corrective action is complete.

10

Subsection 4.3 identified acceptance and conditional acceptance based on noted 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 satisfactorily resolved by June 30, 1982.

The staff issued to the licensee 5ections 3 and 4 of this report and requested, under the provisions of 10 CFR 50.54(f), that the licensee review the deficien-cies enumerated and the ramifications thereof to detarmine whether safe opera-tion of the facility would be impacted in consideration of the deficiencies.

The licensee has completed a preliminary review of the identified deficiencies and has determined that, after due consideration of the deficiencies and their ramifications, continued safe operation would not be adversely affected.

Based on these considerations, the staff concludes that conformance with the above requirements and satisfactory completion of the corrective actions by June 30, 1982 will ensure compliance with the Commission Memorandum and Order of May 23, 1980. The staff further concludes that there is reasonaole assurance of continued safe operation of this facility pending completion of these corrective action. This conclusion is based on the following.

(1) that there are no outstanding items which would. require immediate corrective action to assure safety of plant operation.

(2) some of the items found deficient have been or are being replaced or relocated, thus improving the facility's capability to function following a LOCA and HEL3 (3) the harsh environmental conditions for which this equipment must be qualified result from low procacility events; events wnich might reasonaoly be anticipated during this very limited period would lead to less demanding service conditions for this equipment.
