PARTIAL REVIEW 0F E0VIPMENT EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION FOR MAINE YANKEE ATOMIC POWER COMPANY DOCKET NO. 50-309 3 STAFF EQUIPMENT EVALUATION The staff evaluation of the licensee's response included an onsite inspection of selected Class IE equipment and an examination of the licensee's report for The criteria described in the 00R guidelines completeness and acceptability.
and in NUREG-0588, in part, were used as a basis for the staf f evaluation of the adequacy of the licensee's qualification program.
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 (September 8-11, 1980)
An inspection of equipment of selected safety-related electrical 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 proper installation of equipment, The manufac-overall interface integrity, and manufacturers' nameplate data.
turer's name and model number from the nameplate data were compared to infor-mation given in the environmental qualification work sheets of the licensee's repo'rt.
The site inspection is documented for the Maine Yankee plant in report IE 50-309/80-14.
No deficiencies were noted.
For this review, the documents referenced above have been factored into the overall staff evaluation.
3.1 Completeness of Safety-Related Equipment In accordance with IEB 79-018, the licensee was directed to (1) establish a list of systems and equipment that are required to mitigate a LOCA and an HEL8 and (2) identify the most limiting environmental conditions the equipment may be exposed to and still be required to perform its safety function.
The staff developed a generic master list based upon a review of plant safety analyses and emergency procedures.
The instrumentation selected includes parameters to monitor overall plant performance as well as to monitor the per-formance of the systems on the list.
The systems list was established on the basis of the functions that must be p u formed 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.
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 environment.
The staff therefore 8103110 k b
concludes that the systems identified by the licensee (listed In Appendix D) are acceptable, with the exception of those items discussed in Section 5 of 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 by the licensee.
A complete list of all display instrumentation mentioned in the LOCA and HELB emergency procedures must be provided.
Equipment qualification information in the form of summary sheets should be provided for all components of the display instrumentation exposed to harsh environments.
Instrumentation which is not considered to be safety related tv 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 (2) assurance should be provided that its subsequent failure will not mislead the operator or adversely affect the mitigation of the consequences of the accident.
The environmental qualification of post-accident sampling 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 which are required to perform a safety-related function in a LOCA or a HELB environment.
The licensee provided a summary of the qualification documen-tation and methodology used to qualify safety-related equipment which is required to function in hostile environments.
The remaining bulk of the safety-related equipment was not qualified to the hostile environments on the basis that it is:
(1) required to function only in nonharsh environments, or (2) not required to function for any accident, or (3) not required to function for the accident producing the harsh environmental conditions.
Based on its review of the information provided by the licensee, the staff concludes that this information is incomplete.
The licensee is asked to verify that failure of the equipment identified in the above categories would not be detrimental to safety as a result of a harsh environment.
Failures of this equipment that could lead to disabling a safety function or provide incorrect information to the operator during accident mitigation should be addressed.
In addition, the licensee's response did not identify or provide 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 exemption of this equipment from qualification on some other defined basis.
Also, the licensee has excluded the following safety-related equipment:
(1) pressurizer spray control valve (2) compressed air system (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 D) are acceptable, with the exceptions of those items discussed in Section 5 of this report.
3.2 Service Cct, 11tions Commission Memorandum and Order CL:-80-21 requires that the 00R guidelines and the "For Comment" NUREG-0588 are to be used as the criteria for establishing the adequacy of the safety-related electrical equipment environmental qualifi-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 plant, relative to the temperature, pressure, and the containment spray caustics, has been performed in accordance with the requirements stated above. The staff has reviewed the qualification documentation to ensure that the qualification specifications envelope the conditions established by the licensee.
During this review, the staff assumed that for plants designed and equipped with an automatic containment spray system which satisfies the single-failure crite-rion, the main-steam-line-break (MSLB) environmental conditions are enveloped by the large-break-LOCA environmental conditions.
The staff evaluated the design of the containment spray system and found that the system is not subjected to a disabling single-component failure and therefore satisfies the requirements of Section 4.2.1 of the DOR guidelines.
Equipment submergence has also been addressed where the possibility exists that flooding of equipment may result from HELBs.
3.3 Temperature, Pressure, and Humidity Conditions Inside Containment The licensee has provided the results of accident analyses as follows:
Max Temp ('F)
Max Press'(psig)
Humidity (%)
LOCA 278 54 100 MSLB 340 43 100 The staff has concluded that the minimum temperature profile for equipment qualification purposes should include a margin to account for higher-than-average temperatures in the upper regions of the containment that can exist due to stratification, especially following a postulated MSLB.
Use of the steam saturation temperature corresponding to the total building pressure (partial pressure of steam plus partial pressure of air) versus time will provide an acceptable margin for either a postulated LOCA or MSLB, whichever is controlling, as to potential adverse environmental effects on equipment.
3
The licensee's specified temperature (service condition) of 278*f does not satisfy the above requirement.
A saturation temperature corresponding to the The peak profile (302*F peak temperatore at 54 psig)'should be used instead.
licensee should update his equipment summary tables to reflect this change.
If there is any 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 i
environment associated with an HELB 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 (5) Turbine building The licensee has used 205*f and ambient pressure conditions for areas outside containment.
The staff considers saturation temperature at the peak pressure The licensee resulting from a HELB as the minimum level for acceptance.
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.
3.5 Submergence The maximum submergence levels have been established and assessed by the licensee.
Unless otherwise noted, the staff assumed for this review that the methodology employed by the licensee is in accordance with the appropriate criteria as established by Commission Memorandum and Order CLI-80-21.
The licensee's value for maximum submergence is 1.7 ft.
Equipment below this level has been identified by the licensee, along with the proposed corrective action.
The licensee identified seven safety-related electrical components as As a having the potential for becoming submerged after a postulated event.
corrective action, the licensee proposes replacing these components; in some Cdses, the licensee is considering relocation of the components.
Based on its review of the information submittals by the licensee, the staff concurs with the proposed resolution.
However, because the licensee indicated, in part, that some of the above items complete their safety function before submergence, the staff requires that the licensee supplement this information and provide the time margins before submergence'is assumed in his analysis for all the items identified; the licensee must also verify that subsequent failure of this equipment should not be detrimental to plant safety.
Equipment failure which would result in incorrect information being provided to the operator should al.so be addressed.

The licensee identified the following two items as not subjected to submergence testing:
Item Manufacturer Model PAM-6 level transmitter GEMS XM-36495 CVCS-1 motor operator Limitorque SMB-00 Based on its review of the information submitted, the staf f concludes that the justification for not testing the equipment is incomplete in part.
The staff requires that the licensee 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 assessrant of equipment failure which results in incorrect information being kwvided to the operator.
On the condition that the open items identified above are satisfactorily resolved, the staff concludes that the applicant's response satisfies the Commission requirements identified in IEB 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 Spray The licensee's FSAR value for the chemical concentration is 1750 ppm boric acid solution at a pH of 9.5.
During the review, the staf f 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 staf f will review the applicant's response when it is submitted and present its resolution in a supplemental report.
3.7 Aging Section 7 of the 00R guidelines does not require a qualified life to be estab-lished for all safety-related electrical equipment.
However, the following actions are required:
(1) Make a detailed comparison of existing equipment and the materials identified in Appendix C of the 00R guidelines.
The first supplement to IEB-79-01B requires licensees to utilize the table in Appendix C 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.
(3) Establish component maintenance and replacement schedules which include considerations of aging characteristics of the installed components.
The licensee indentified a number of equipment items for which a specified qualified life was established (for ex' ample, 7.7 years, 20 years, or 40 years). In its assessment of these submittals, the staff did not review the adequacy of the methodology nor the basis used to arrive at these values; the 5
staff has assumed that the established values are based on state-of-the-art technology and are acceptable.
For this review, however, the staff requires that the licensee submit supple-mental information to identify and verify the dace e of conformance to the above requirements.
The response should include
.1 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 licensee 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 determined in accordance with the prescribed criteria.
The staff review determined that the values to which equipment was qualified enveloped the requirements identified by the licensee.
The value required by the licensee inside containment is between 1.1 x 106 to 1 x 108 rads for the integrated dose.
These values do not envelope the 00R guideline requirements (4 x 107 rads) and therefore are not 'cceptable.
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 chosen, then the analysis, including the basis and assumptions used in the analysis and a sample calculation, should be provided.
The licensee ~ stated that the radiation doses to equipment in areas where radioactive fluids are recirculated from inside the containment fnr long-term core' cooling have been calculated in accordance with IES 79-01 Supplement 2 and the "For Comment" NUREG-0588.
In addition, the licensee stated that because of preliminary results from recent HELB and heat-up studies, many areas previously believed to be nonharsh have now been determined to be harsh.
The licensee is in the process of reevaluating the adequacy of the equipment qualification for these outside containment areas.
The staff will review the licensee's resolution when it is submitted and discuss the evaluation in a supplemental report.
4 QUALIFICATION OF EQUIPMENT j
The following subsections present the staff's assessment, based on the licensee's submittal, of the qualification status of safety-related electrical equipment.
I The staff has separated the safety-related equipment into three categories:
(1) equipment requiring immediate corrective action, (2) equipment requiring additional qualification information and/or corrective action, and (3) equip-l ment considered acceptable if the staff's concern identified in Section 3.7 is satisfactorily resolved.
l In its assessment of the licensee's submittal, the NRC staff did not review the methodology employed to determine the values established by the li ensee.
f 6
However, in reviewing the data sheets, the staff made a determination as to the stated conditions presented by the licensee.
Additionally, the staff has not completed its review of supporting documentation referenced by the licen-It is expected that when the review of test see (for example, test reports).

The staff has determined that an acceptable basis.o exempt equipment from qualification, in whole or part, can be established rovided 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 before its exposure to the harsh environ-ment, and the adequacy for the time margin provided is adequately justified, and (2b) Subsequent 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 accomplished by some other designated equipment that has been adequately qualified and satisfies the single-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 should include a description of the corrective action, schedules for its completion (as applicable), and so forth. The staff will review the licensee's response, when it is submitted, and discuss the resolution in a supplemental report.
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 Equipment Considered Acceptable or Conditionally Acceptable 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 qualifi-cation program adequately enveloped the specific environmental plant parameters, or (2) conditionally acceptable subjec,t to the satisfactory resolution of the staff concern identified in Section 3.7.
8
For the equipment identified as conditionally acceptable, the staff determined 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, (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 established.
The staff will review the licensee's response when it is sub-mitted and discuss the resolution in a supplemental report.
5 DEFERRED REQUIREMENTS IEB 79-01B, Supplement 3 has relaxed the time constraints for the submission of the information associated with cold shutdown equipment and TMI lessons-learned modifications.
The staff has required that this information be provided by February 1,1981.
The staff will provide a supplemental safety evaluation addressing these concerns.
