3. General Information 3.1 Identification of Class 1E Electrical Ecutoment The licensee's list of systems was compared to the systems list issued by the Equipment Qualification Branch (EQB) and discussed in Section 4.1 of this report.

It is recognized that tnere are differences in nomenclature of systems because of plant vintage and engineering design, therefore, many of these systems may not exist or nave different titles. These differences will be addressed in the Safety Evaluation Report (SER) that will be prepared for this site.

3.2 Service Conditions The service condition accident environment, HEL3/LOCA inside contain-ment and HELS outside containment are indicated or discussed in the licensee's report and are cased on the FSAR accicent analysis and Section 4.3 of this report. ,

3. 3 Oualification Documentation Appendix A is a list of documents (test reports, analysis, letters, ete ) used by the licensee in determining the environmental qualif-ication of plant equipment for Maine Yankee Atomic Power Company.

These references have been tabulated by the licensee and are indicated on the applicaole Environmental Qualification Worksneets of Oneir report.

4 Tecnnical Evaluation i The basis for the technical evaluation is the informatiog provided by Yankee Atomic Electric Company (YAEC) in their submittal YAE(-1229,

. dated October 31, 1980, for the Maine Yankee Atomic Power Company and the I verification inspection of the as-installed equioment of tne Main Steam System, Hign Pressure Safety Infection System and Containment Soray System. The installation verification consistec of an insoection of comoonents located outside primary containment that could oe exoosec to a narsn environment and documented oy IE Insoection Report 50-309/30-14 Utili:ing the information identified aoove 5 tne reviewec assessec its ,

Service Water System The list of systems including those that were excluded was provided The EQB compared the to the Equipment Qualification Branch (EQg)a. nd to the lists provided list to a "Q" list developed by the staff by similar facilities to determine the completeness of the licensee's response.

Based on the information provided by the licensee and the reviewers comparison, the reviewer has determined that the systems icentified are sithin the guidance provided in Section 3 0 and Apoendix A of ne 00R Guidelines'. However, cecause the licensee nas icentifiedt systems anc comoonents, it does not necessarily mean :ne licensee intends to qualify those systems and comoonents.

The licensee has providec a Master List of safety-related electrical ,

equipment normally availacle for accident mitigation and cringing  !

the plant to cold shutdown status. The Master List is cased on :ne i systems identified aoove, =hich originates from Table I.1 of the submittal" and identifies the electrical equipment whicn is reouirec to function under postulated accident conditions. Ecuipment is 3 l identified as such by a reference to Appendix II of the suomittal environmental qualification worksheet. Electrical equipment

(1) Required to function under non-harsh environtiental conditions.

l (2) Not required to function for any accident.

(3) Not required to function for the accident producing One harsh environmental conditions.

Additionally, the licensee has identified other safety-related electrical equipment that will not have an environmental qualifica-ion worksheet because:

i (1) The equipment is not required for mitigation of design basis accidents; however, it is useo to maintain Tecn Specs prior to an accident.

Therevieweridentifiedsafety-relat3delectricalequipmentthattne licensee identified in the sucmittal as not requiring environmental qualifications. The licensees justification for not qualifying

The reviewer has reviewed the master list for the inclusion of equipment and has the following comment:

The licensee's submittal3 does not identify terminal lugs, caole splices, instrument and terminal box sealant material, terminal

! boxes, penetration connection boxes, rigid conduit, and flexible conduit.

The above components identified by the reviewer will be evaluated oy the EQB and addressed, if applicable, in tr.e 5ER to be written for this facility. (Qualification of Equipment Unresolved, Category IV) 4.3 Service Condition 4.3.1 Inside Containment LOCA The licensee provided temperature and pressure profiles for the Maine Yankee containment resulting from a LOCA.

The reactor containment temperature and pressuge profiles, Figures III.1-1 and III.1-2 of their suomittal , are based upon a re-analysis of the LOCA and Main Steam Line 3reak (MSLS) performed by Comoustion Engineering during the

• uprating of Maine Yankee

• to 2530 MW thermal. The temoerature and pressure profiles for the new LOCA, in these figures, do not return to the oper1 ting conditions specified cefore the LOCA.

The LOCA temcerature and pressure profiles prior to Maine Yankee's uprating are also shown in Figures III.1-1 and III.1-2. These profiles were obtained from Maine Yankee FSAR Figures 14.15-2 and 14.15-3. The maximum environments identified are:

Temperature: 278 F Pressure: 54 PSIG Humidity: 100%

Chemical Soray: 1720 PPM Baron as H 30 1 pH = 9.5 Radiation: Maximum not stated 3 3 The delay time from the event to tne initiation of safety l injection for the spectrum of creaks is indicatec in :5AR Section 14.15-2, l

4. 3.1.1 Temoerature and Pressure Profiles The temperature and pressure profdles for tng new LOCA, Figures III.1-1 and III.1-2 of the sucmittal , extend only l 100 seconds foto the accident.

7 The reviewer has concluded that the above information is incomplete.

4.3.1.2 Radiation The licensee does not state a maximum radiation dose in the submittal'. The radiation dose values for the ecuipment have been identified in the equipment qualification worksheets. j The licensee casis for determining the radiation doses to equipment required to function during aiid af ter a LOCA have been calculated in accordance with Supplement #2 of the IES79-018 and the COR Guidelines.

The reviewer will address equipment in Section 4.9 of this report that do not meet the radiation doses required by i the guidelines.

4. 3.1. 3 Submergence The licensee identified the flood level as 1.7 feet. The l acceptacility of the licensee's basis fdr specific equipment subjected to submergence is included.in Section 4.9 of this report.

4.3.1.4 Chemical Scrav The licensee identifiea the requirement for the containment sprays to me at least 1720 ppm boric acid solution. This requirement is contained in the Maine Yankee Technical Specifications, Section 3.5. The consideration of sprays i is included in Section 4.9 of this report.  !

Subsections 4.3.1.1, 4.3.1.2, 4.3.1.3 and 4.3.1.4 above contain unresolved items and are considered: (Category IV, Qualification of Equipment Unresolved).  ;

4.4 Hign Energy Line Breaks (HELB) 4.4.1 HEL3 Insice Containment The Maine Yankee facility has an automatic containment spray system. The OCR Guioelines", Section 4.2.1, indicates that LOCA qualified equipment inside containment is acceptacle for HELBs if tne automatic spray system is not suoject to disaoling single component failures.

The reviewer performed a single failure evaluation of tne containment scray system. It appears that the system is not suojected to a disabling single component f ailure in accordance to the requirements of the JOR Guidelines *,

Section 4.2.1, and that the LOCA qualified equiement inside containment is accaptable for HEL3s.

l However, the gSLB temperature profile, Figure III.1-1 of the,F.

340 submittal Because , indicates this peaka is peak temperature of such of approximately short duration,100 seconds, the licensee considered the effect on equipment j qualification as minimal.

i 4,4.2 HELS Outside containment The licensee's May 1980, suomittal l0 indicated that

" Supplemental Report on Effects of Postulated Break in a Hign Energy Piping System Outside the Containment,"

Septemoer1973,providetheresultsoftgeirreviewof high energy line breaks. The sucmittal' indicated that the environmental radiations nad no adverse effect on safe shutdown of the plant in all cases analyzed.

However, the licensee's October 1980, submittal 3Apoendix III notes:

"Because of preliminary results from recent HEL3 and Heat-up studies, many areas previously be!ieved to be non-narsh

• have now been determined to be harsh. The imcact on equipment qualification has yet

• to :e fully analy:ed ,anc

• resolved."

The specific equipment wnere this applies is included in Section 4.9 of this report as: (Category IV, Quali fication of Equipment Unresolved. )

Appendix III of the suomittal contains the environmental service conditions uncer whien certain safety-relatec electrical equipment is required to function. The following sections of Appendix III address the various HEL3 envirormenta!

parameters for the: ,

(1) Primary Auxiliary Building /Auxil f ary Feeeaatar ?umo Area (2) Steam and Feeowater Valve Area (3) Turcine Building .

The main steam line atmosphgric duma valves nave ~ceen identified in the submittal as "Not required to function for any accicent." These same valves are described in Section 7 of the eptemoer 1973 report. as being needed to maintajnthereactorc:olantsystemcoolcownratenithin the 50 F per nour design limit prescribed in the FSAR.

These valves have been identified as (Category IV, Qualifica-tion of Equipment Unresolved) in Section 4.1 aoove.

9 4.4.3 Recirculated Fluids 3

Appendix III of the licensee's submitta1 contains the environmental service conditions under wnich certain safety-related electrical equipment is required to function.

The following sections of Appendix III address the various l recirculated fluids . environmental parameters for the:

(1) Primary Auxiliary Building / Auxiliary Feeowater cumo Area (2) Spray Pump Area The acceptability of the parameters identified and the basis for specific equipment qualification are included in Section 4.9 of this report.

4.5 Margins The 00R Guidelines indicate that special consideration was given to tha time reouired to remain functional when establishing the criteria o in Section C.2 of the guidelines.

NUREG-0588, Section 3(4), requires that a type test be for a minimum l of 1 nour in duration when the functional recuirement is within the first seconds or minutes of an event and the 00R guidelines, Section 5.2, requires that the test duration be at least as long as the i period from initiation until the service canaitions return to tne i level that existed prior to the event.

Therefore, any type test that exceecs the functional operability time by 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or longer meets the requirements defined in NUREG-0588 and the 00R guidelines for margin in relation to test duration for this facility.

l l The other consideration identified in the 00R guidelines in relation to the methods of qualification, other tnan identified soecifically in this report will ce addressed in One Safety Evaluation Reoort (SER) wnich uill incorporate an audit of selected analysis anc test reports identified in Appendix A.

l The considerations of margins is included in Section 4.9 of tnis report. Equipment with questions is classified: (Category U/,

The licensee has identified the components which are still listed as l' requiring data.

The 00R guidelines,. 5ection 7, does not require a qualified life to be established for all safety-related electrical equipment, however, the following actions are' required:

I

1. Detailed comparison of existing equipment to the materials identified fn 4

Appendix C of the 00R guidelines. The first supplement to IES79-018 requires the licensees to utilize the table and identify any additional materials as the result of

.their effort.

2. Establish an ongoing program to review surveillance and maintenance records to identify potential age related degradations, i

3. Establish component maintenance and replacement schedules which include considerations of aging characteristics of the installed components.

l i '

We, therefore, require that the licensee provide the details of a program which wi41 include a. continuing effort to obtain data on  ;

, existing materials and address tne actions identified acove. In i dddition, we require the licensee provide a senedule for implementation of the program that identifies problem components.

The considerations of aging is included in Section 4.9 of tnis i report. Equipment with questions is classified: (Category !V, .

Appendix B 1 NOTES

1. The qualified radiation data provided is for the actuator excluding the motor. The licensee is presently workirg with Limitorque Corp. to obtain.

radiation tolerance data for'these motors. This information will ce available for review on completion.

2. -The' solenoid operated valves currently installed are ASCO EH8X8320 and

'8311A31F. Although the valves operate ':sfore the abnormal environment

. associated with the accident has an opportuni*/ to develop, we have assigned a' one hour operating time per icoplement #2 of IES79-018.

'Sased on the above, it is planned to reciace these valves with the ASCO NP-1 Series valve which is fully qualif'ed for LOCA and HEL3 environments.

l 3. 'Secause of preliminary results from recent HELS and Heat-Up studies, many areas previously belfered to be non-hars, have now been determined to be harsh. The impact on equipment qualification has yet to be fully analyzed and resolved; and therefore, the conclusions reacned herein ar,e to be considered preliminary.

4 Qualification of this component for the recuired operating time has been determined to be adequate based on an evaluation of the qualifiction data used to qualify it for all applicaole environmental carameters indicated on this worksheet (See Reference 038). .

6

5. The transmitters have been qualified for 3.5 x 10 R. The licensee refers to reference 1025, in Appendix A as tne documentation to wnich these transmitters are qualified.

6. Aging qualification is under investigation and will be provided wnen completed.

l 7. Qualification is ceing done by the vencer under a generic utility program

! scneduled for comoletion oy June 1981.

S. The vendor is currently testing these components to accress al'1 the environmental parameters. Comolete test recorts will ce available for review on completion.

l

9. This equipment is included oecause of NUREG-0573.
