INTRODUCTION 1.1 PURPOSE OP THE REVIEW The NRC Office of Inspection and Enforcement (ZE) issued Bulletin 79-01B, "Environmental Qualification of Class 1E Equipraent" in January 1980.

This Bulletin required the Licensee to perform a detailed evaluation of the environmental qualification of Class 1E electrical equipment required to function under postulated accident conditions and to submit a report on this action.

The objectives of the NRC Equipment Environmental Qualification Review program are to evaluate nuclear power plant safety-related electrical equipment in accordance with criteria established by the NRC and to identify (1) equipment whose qualification documentation is adequate, i.e.,

substantiates that equipment is capable of performing its specified design basis safety function when it is exposed to a harsh environment and (2) equipment whose qualification documentation is deficient, i.e.,- does not give reasonable assurance that the equipmerrt is capable of performing it specified safety function.

To meet the overall program goals, the objective of this Technical Evaluation Report is to review the Licensee's submittals to determine if the Licensee reviewed its safety-related electrical equipment for environmental qualification in accordance with the DOR Guidelines and NUREG-0588 as required by ZE Bulletin 79-01B.

The NRC will perform an audit of the qualification documentation references as part of its safety evaluation program.

Zf discrepancies are found, the audit will be extended.

l. 2 GENERIC ISSUE BACKGROUND Safety-related electrical equipment must be capable of performing design safety functions under all normal, abnormal, and accident conditions.

Of particular concern is the assurance that equipment will remain operable during 00 Franklin Research Center ADlvleion el The Fcenicrin lncecuce

TERM5 417-4 and following exposure to the harsh environmental conditions (i.e.,

temperature,

pressure, humidity (steam),

chemical sprays, radiation, and submergence) imposed as a result of a design basis accident.

These harsh environments are generally defined by the limiting conditions resulting from the complete spectrum of postulated break sizes, break locations>

and single failures consequent to a loss-of-coolant accident (LOCA), main steam line break (MSLB) inside the reactor containment, or a high energy line break (HELB) outside reactor containment (such as a main steam or feedwater line break).

The purpose of equipment qualification is to provide tangible evidence that equipment will operate on demand and to verify design performance, thereby establishing assurance that the potential for common-mode failure is minimized.

Qualification criteria applied during the licensing of the older nuclear plants have been modified over the years, and industry standards concerning qualification have been revised as the design of reactor systems has changed and as regulatory and operating experience has accumulated.

Examples of such standards are IEEE Standards 279-71, 323-74, 383-74, 317-76, 334-74, 382-72, and 381-77.

NRC NUREG documents 0413 and 0588 have been developed to address this topic.

In particular, NUREG-0588 (published for comment in December 1979) formally presented the NRC staff positions regarding selected areas of environmental qualification of safety-related electrical equipment in the resolution of General Technical Activity A-24, "Qualification of Class lE Safety Related Equipment."

The positions documented therein are applicable to plants that are or will be in the construction permit or operating license review process.

Although qualification standards and regulatory requirements have undergone considerable development, all of the currently operating nuclear power plants are required to comply with 10CFR50, Appendix A, General Design Criteria for Nuclear Power Plants,Section I, Criteria 4.

This criterion states in part that "structures, systems and components important to safety shall be designed to accommodate the effects of and to be compatible with the environmental conditions associated with normal operation, maintenance,

testing, and postulated accidents, including loss-of-coolant accidents."

4.

~IIII Franklin Research Center rtk Ofsrt4fotk ttfIhe F4RFtktftn ittsttftrtc 1-2

TERM5417-4 Zn addition, qualification requirements are also embodied in 10CFR50 Appendix A, General Design Criteria 1, 2, and 23 and Appendix 8, Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing

Plants, Criteria III and XI.

These requirements are applicable to safety-related equipment located inside as well as outside of containment.

The NRC staff has evaluated the Licensee's equipment qualification program by reviewing the qualification documentation of selected safety-related equipment as part of the operating license review for each plant.

The NRC staff has also used a variety of methods to assure that these general requirements are met for electrical safety-related equipment.

In the oldest plants, qualification was based on the fact that electrical components were of high industrial quality.

After 1971, qualification was judged on the basis of IEEE 323-71;

however, no regulatory guide was issued adopting the IEEE 323-71 standard.

For plants whose Safety Evaluation Reports were issued after July 1, 1974, the Commission issued Regulatory Guide 1.89 which in most respects adopted the most recent standard, ZEEE 323-74.

In 1977, the NBC staff instituted the Systematic Evaluation Program (SEP) to determine the degree to which the older operating nuclear plants deviated from current licensing criteria.

The subject of electrical equipment environ>>

mental qualification (SEP Topic ZZZ-12) was selected for accelerated evalua-tion as part of this pLogram.

Seismic qualification of equipment was to be addressed as a separate SEP topic.

Zn December

1977, the NRC issued a generic letter to all SEP plant Licensees requesting that they initiate reviews to determine the adequacy of existing equipment qualification documentation.

Preliminary NRC review of Licensee responses led to the preparation of NUREG-0458, an interim NRC assessment of the environmental qualification of electrical equipment.

This document concluded that "no significant safety deficiencies requiring immediate remedial actions were identified."

However, it was recommended that additional effort should be devoted to examining the installation and environmental qualification documentation of specific electrical equipment in all operating reactors.

TERM5 417-4 On May 31, 1978, the NRC Office of Inspection and Enforcement issued ZE Circular 78-08, "Environmental Qualification of Safety-Related Electrical Equipment at Nuclear Power Plants," which required all Licensees of operating plants (except those included in the SEP program) to examine their installed safety-related electrical equipment and ensure appropriate qualification documentation for equipment function under postulated accident conditions.

Subsequently, on February 8, 1979, the NRC Office of Inspection and Enforce-ment issued ZE Bulletin 79-01, which was intended to raise the status of IE Circular 78-08 to the level of Bulletin, i.e., action requiring a Licensee response.

This Bulletin required a complete re-review of the environmental qualification of safety-related electrical equipment as described in ZE Circular 78-08.

The review of the Licensee responses indicated certain deficiencies within the scope of equipment addressed, definition of harsh environments, and adequacy of support documentation.

Zt became apparent that generic criteria were needed to evaluate the electrical equipment environmental qualification for both SEP and non-SEP operating plants.

Therefore, during the second half of 1979, the Division of Operating Reactors (DOR) of the NRC issued internally a document entitled- "Guidelines for Evaluating Environmental Qualification of Class 1E Electrical Equipment in Operating Reactors."

(The document is hereafter referred to as the "DOR Guidelines.")

The document was prepared as a screening standard for reviewing all operating plants, including SEP plants.

Originally it was intended that the Licensees would evaluate their qualification documentation in accordance with the DOR Guidelines.

However, initial NRC review of this documentation, which was compiled to support Licensee submittals, revealed the need for obtaining independent evaluations and for accelerating the qualification review program.

Zn October 1979, the NRC awarded Franklin Research Center (FRC) a contract to provide assistance in the "Review and Evaluation of Licensing Actions for Operating Reactors,"

which included an assignment for review of

, equipment environmental qualification under SEP Topic ZII-12.

FRC was given the assignment to review equipment environmental qualification documentation It'll Franklin Research Center A Glvoion d lhe Fraetin Insotu(e 1-4

TER-C5417-4 and to present the results in the form of a Technical Evaluation Report for each plant included in this program.

On January 14,

1980, the NRC Office of Inspection and Enforcement issued the DOR Guidelines and IE Bulletin 79-01B, which expanded the scope of ZE Bulletin 79-01 and requested additional information on environmental qualification of safety-related electrical equipment at opezating facilities, excluding the ll facilities undergoing the SEP review.

This Bulletin stated that the criteria to be used in evaluating the adequacy of the safety-related electrical equipment qualification are the DOR Guidelines.

The scope of the review was expanded to include high energy line breaks (inside and outside containment) in addition to equipment aging and submergence.

The NRC advised the Licensees that the criteria contained in the DOR Guidelines would be used in its review of Licensee submittals; problems arising from this review would be resolved using NUREG-0588 as a guide.

In early February

1980, the NRC decided that Indian Point Units 2 and 3

and Zion Units 1 and 2 should be included within SEP Topic IZZ-12 foz the purpose of equipment environmental qualification review.

On February 21,

1980, the NRC and representatives of the SEP Plant Owners Group held an open meeting at NRC headquarters to discuss an accelerated review program in accordance with the DOR screening guidelines.

Represen-tatives of the Indian Point Units and Zion Station also attended this meeting.

The NRC formally issued to all Licensees represented at the meeting the DOR,Guidelines document

[64)* which included a second

document, "Guidelines for Identification of That Safety Equipment of SEP Operating Reactors for Which Environmental Qualification Zs To Be Addressed,"

[64]

together with the request that the Licensees zeview their plant systems and provide additional equipment environmental qualification information to the NRC on an accelerated schedule.

For non-SEP plants, the NRC Office of Inspection and Enforcement formed a task force including a principal reviewer in each region and a task leader from headquarters.

The regional members are re'sponsible for the technical

TERMS 41 7-4 review of the Licensees'esponses to IE Bulletin 79-01B, and the task leader is responsible for the overall coordination of the review effort with NRC to assure overall consistency.

The regional reviewers held meetings with the Licensees in their respective regions which-resulted in staff positions being, issued in a supplement to IE Bulletin 79-01B dated February 29, 1980.

In April 1980, the NRC organizational structure was modified and the Equipment Qualification Branch was formed within the new Division of Engi-neering.

Responsibility for reviewing the status of equipment qualification for all plants was assigned to this branch.

On May 27, 1980, the NRC issued Memorandum and Order CLI-80-21r [67]

specifying that Licensees and applicants must meet the requirements set forth in the DOR Guidelines and NUREG-0588 regarding environmental qualification of safety-related electrical equipment in order to satisfy

10CFR50, Appendix A, General Design Criteria,Section I, Criterion 4.

This Order also established that the Safety Evaluation Reports on this subject, to be prepared by the NRC staff, must be issued on February 1,

1981 and that all subsequent actions to be taken by Licensees to achieve full compliance with the DOR Guidelines or NUREG-0588 must be completed no later than June 30, 1982.

In October 1980, EG&G awarded Franklin Research Center (FRC) a contract to provide assistance in the equipment environmental qualification review for 13 of the plants whose Licensees responded to IE Bulletin 79-01B.

FRC was given the assignment to evaluate the Licensee's equipment environmental qualification submittal and to present the results in the form of a Technical Evaluation Report for each plant.

1,3 SPECIFIC ISSUE BACKGROUND The staff held regional meetings with the Licensees and interested parties during the week of July 13, 1980 in various locations.

The staff issued a second supplement to IE Bulletin 79-01B, a response to significant questions raised during the public meetings, and two Orders.

The Order dated May 30, 1980 required the Licensees to comply with the previously issued Commission Memorandum and Order of May 27, 1980 (CLI-80-21).

The above Orders.

ll0ll Franklin Research Center ADivision ot The Frank)in Insame 1-6

TERM5417-4 required the Licensees to complete the tasks identified in IE Bulletin 79-01B no later than November 1,

1980 to allow the staff to comply with the February 1, 1981 date imposed by the Commission Order.

The responses to the questions were issued on February 29< 1980; and the second and third supplements to IE Bulletin 79-01B, highlighting the staff positions affecting the Licensees'esponses, were issued September 29 and October 24, 1980, respectively.

1.4 SCOPE OF THE REVIEW Environmental qualification of safety-related electrical equipment was

'selected by the NRC for accelerated review.

Therefore, the scope of this report is limited to equipment that must function to mitigate the consequences of a loss-of-coolant accident (LOCA) or high energy line break (HELB) and whose environment is adversely affected by that event.

In addition, IE Bulletin 79-01B requires enviromental qualification for all safety-related electrical equipment exposed to a harsh environment in accordance with the DOR Guidelines or NUREG-0588.

Harsh environments include the limiting conditions resulting from (i) the entire spectrum of postulated line breaks resulting from a loss-of-coolant accident (LOCA) or a high energy line break (HELB) inside and outside of containment end (ii) radiation from fluids which are recirculated from inside containment to accomplish long-term cooling subsequent to an accident.

Qualification aspects not included within the scope of this evaluation are:

~

seismic qualification

~

equipment protection against natural phenomena

~

equipment operational service conditions (e.g., vibration, voltage, and frequency deviations)

~

equipment located where it is sub)ect to outdoor environments

~

equipment protection against fire hazards

~

equipment protection against missiles.

TERMS 417-4 2.

NRC CRITERIA FOR ENVIRONMENTAL QUALZFICATlON 2.1 CRITERIA PROVIDED BY THE NRC The DOR screening guidelines used by FRC to evaluate the electrical equipment environmental qualification program were:

~

"Guidelines for Evaluating Environmental Qualification of Class 1E Electrical Equipment in Operating Reactors"

[64]

~

"Guidelines for Identification of That Safety Equipment of SEP Operating Reactors for Which Environmental Qualification Is To Be Addressed"

[64]

~

NUREG-0588, "Interim Staff Position on Environmental Qualification of Saf ety-Related Electrical Equipment. " [69]

These guidelines were issued by the NRC in February 1980 for implementation by all Licensees.

2 ~ 2 STAFF POSITIONS AND SUPPLEMENTAL CRITERIA The NRC identified the following staff positions and supplemental criteria to be used in conjunction with the referenced DOR screening guidelines.

2'.1 SERVICE CONDITIONS INSIDE CONTAINMENT FOR A LOSS-OF-COOLANT ACCIDENT (DOR GUIDELINES SECTION 4.1)

For Pressurized Water Reactors (PWRs),

the DOR Guidelines state that the containment temperature and pressure conditions as a function of time should be based on the most recent NRC-approved service conditions specified in the Final Safety Analysis Report (FSAR) or other Licensee documentation.

In the specific case of pressure-suppression type containments, the following minimum high temperature conditions may be used:

(1) Boiling Water Reactor (BWR)

Drywells 340'F for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and (2)

PWR Ice Condenser Lower Compartments 340'F for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />.

As stated in Supplement 2 to IE Bulletin 79-01B,

[65]

"these values are a screening

device, per the Guidelines, and can be used in 0(ill Franidin Research Center A Damson d The Fani4n Insatute 2-1

TER-C5 417-4 lieu of a plant-specific profile, provided that expected pressure and humidity conditions as a function of time are accounted for."

Service conditions should bound those expected for coolant and steam line breaks inside containment with due consideration given to analytical uncertainties.

The steam line break condition should include superheated conditions, with peak temperature and subsequent temperature/pressure profile as a function of time.

If containment spray is to be used, the impact of the spray on required equipment should be accounted for.

The adequacy of a plant-specific profile is dependent on the assumptions and design considerations at the time the profiles were developed.

The DOR Guidelines and NUREG-0588 provide guidance and considerations required to determine if the calculated plant-specific temperature/pressure profiles encompass the LOCA and HELB accidents inside containment.

2 ~ 2 ~ 2 SUBMERGENCE (DOR GUIDELINES SECTZON 4 1 g SUBITEM 3 and SECTION 4 ~ 3 ~ 2g SUBITEM 3)

-Equipment submergence (inside or outside containment) should be addressed where the possibility exists that submergence of equipment may result from HELBs or other postulated occurrences.

Supplement 2 to IE Bulletin 79-01B

[65] provides the following additional criterion: If the equipment satisfies the guidance and other requirements of the DOR Guidelines or NUREG-0588 for the LOCA and HELB accidents, and the Licensee demonstrates that its failure will not adversely affect any safety-related function or mislead the operator after submergence, the equipment can be considered exempt from the submergence portion of the qualification requirements.

2 ~ 2 3

EQUIPMENT LOCATED IN AREAS NORMALLY MAINTAINEDAT ROOM CONDITIONS (DOR GUIDELINES SECTION 4 ~ 3 ~ 3)

Supplement 2 of IE Bulletin 79-01B [65] permits deferment of the review of environmental qualification for all safety-related equipment items located in plant areas where the equipment is not exposed to the direct effects of a HELB or to nuclear radiation emanating from circulation of fluids containing radioactive substances.

At the Licensee's option, the review may be deferred until after February 1, 1981.

Il/ll Frankiin Research Center ADizen ot The Frsnkln tnsatutc 2-2

TERMS 417-4 By June 30, 1982, all safety-related electrical equipment potentially exposed to a harsh environment in nuclear generating stations licensed to operate on or before'une 30, 1982 shall be qualified to either the DOR Guidelines or NUREG-0588 (as applicable)

Safety-related electrical equipment is that required to bring the plant to a cold shutdown condition and to mitigate the consequences of the accident; It is the responsibility of the Licensee to evaluate the qualification of safety-related electrical equipment to function in environmental extremes not asscciated with accident conditions and to document it in a form that will be available for the NRC to audit.

Qualification to assure functioning in mild environments must be completed by June 30, 1982.

2. 2. 4 SZMULATED SERVICE CONDZTZONS AND TEST DURATION (DOR GUIDELINES SECTION 5.2.1)

The Guidelines require that the test chamber environment envelop the required service conditions for a time equivalent to the period from the initiation of the accident until the service conditions return to normal.

Supplement 2 to IE Bulletin 79-01B [65] provides the following additional criterion:

"Equipment designed to perform its safety-related function within a short time into an event must be qualified for a period of at least 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> in excess of the time assumed in the accident analysis.

The staff has indicated that time is the most significant factor in terms of the margins required to provide an acceptable confidence level that a safety-related function will be completed.

The 1-hour qualification requirement is based on the acceptance of a type test for a single unit and the spectrum of accidents (small and large breaks) bounded by the single test."

2.2.5 DEFERMENT OF QUALIFICATION REVIEW Supplement 3 to IE Bulletin 79-01B [66] permits the submittal of qualification documentation regarding the TMZ Action Plan equipment and the equipment required to achieve and maintain a cold shutdown condition to be delayed as follows:

a Qualification information for installed TMZ Action Plan equipment must be submitted by February 1,

1981.

(ll Franklin Research Center A Dlvlsknd The FrankHn Insatute 2-3

TER-CS 417-4

~

Qualification information for future TMI Action Plan equipment (reference NUREG-0737, when issued),

which requires NRC pre-implementation review, must be submitted with the pre-implementation review data.

~

Qualification information for TMZ Action Plan equipment currently under NRC review should be submitted as soon as possible.

~

Qualification information for TMI Action Plan equipment not yet installed that does not require pre-implementation review should be submitted to NRC for review by the implementation date.

~

Qualification information for equipment required to achieve and maintain a cold shutdown condition should not be submitted later than February 1< 1981.

2 2.6 TEST SEQUENCE (DOR GUIDELINES SECTION 5. 2 ~ 3)

Supplement 2 to IE Bulletin 79-01B (65] provides the following additional criteria:

"Sequential testing requirements are specified in NUREG-0588 and the DOR Guidelines.

Licensees must follow the test requirements of the applicable document.

l.

Zf the test has been completed without aging in sequence>

justification for such a deviation must be submitted.

2.

Zf testing of a given component has been scheduled but not initiated, the test sequence/program should be modified to include aging.

3.

Test programs in progress should be evaluated regarding the ability to comply by incorporating aging in the proper sequence.

These programs would then fall in the first or second category."

2.2 7

RADIATION (DOR GUIDELINES SECTIONS 4.1.2, 4.2.2, and 4.3.2, SUBITEM 2)

Supplement 2 to IE Bulletin 79-01B [65] provides the following additional criteria:

"Both the DOR Guidelines and NUREG-0588 are similar in-that they provide the met:hods for determining the radiation source term when considering LOCA events inside containment (100% noble gases/50%

iodine/1% partic-

.ulates).

These methods consider the radiation source term resulting from an event which completely depressurizes the primary system and releases the source term inventory to the containment.

2-4 00 Franklin Research Center A 0M@on ot The Frsnk5n Insutu(e

TERM5417-4 NUREG-0578 provides the radiation source term to be used for determining the qualification doses for equipment in close proximity to recirculating fluid systems inside and out:side containment as a result of LOCA.

This method considers a

LOCA event in which the primary system may not depressurize and the source term inventory remains in the coolant.

NUREG-0588 also provides the radiation source term to be used for qualifying equipment following non-LOCA events both inside and outside containment (10% noble gases/10%

iodine/0% particulates)

When developing radiation source terms for equipment qualification, the Licensee must, ensure consideration is given to those events which provide the most bounding conditions.

The following table summarizes these considerations (RCS ~ reactor coolant system):

LOCA Non-LCCA HELB Outside Containment NUREG-0578 (100/50/1 in RCS)

NUREG-0588 (10/10/0 in RCS)

METHODOLOGY USED BY FRC IE Bulletin 79-01B required the Licensee to:

~

provide a master list which identifies the systems and electrical equipment required to function during and subsequent to an accident and to maintain the plant in a safe condition

~

provide the environmental service conditions

~

identify the submergence levels

~

provide written evidence of the qualification of the equipment identified

~

evaluate the qualification documentation using the DOR Guidelines and NUREG-0588

~

submit a Licensee Event Report (LER) for electrical equipment determined not to be environmentally qualified.

The requirements of ZE Bulletin 79-01B were requested under provisions of 10CFR50.54(f)

> "Conditions of Licenses,"

which requires the Licensee to submit written statements, signed under oath or affirmation, to enable the Commission to determine whether or not a license should be modified, suspended, or revoked.

To provide assurance that the Licensee implemented the requirements of ZE Bulletin 79-01B and to provide a basis for the NRC Safety Evaluation Report (SER),

FRC developed this Technical Evaluation Report (TER) by:

~

assessing the Licensee's responses in relation to the general requirements of the DOR Guidelines as augmented by the supplements to the 79-01B Bulletin

~

using NUREG-0588 to resolve open issues.

The results and conclusions contained in this report are valid assuming that the Licensee's analyses of test reports referenced in the Licensee submittal are correct.

The Licensee, Tennessee Valley Authority, identified an extensive list of safety-related electrical equipment items in various locations of, the Browns Ferry Nuclear Power Station Unit 1 in its submittals to the NRC.

FRC analyzed the Licensee's listing and grouped together all identical equipment items located within plant areas that are exposed to the same environmental service conditions.

This analysis resulted in a reduced listing containing 140 different equipment items that formed the basis for the review.

Appendix A

contains the environmental service conditions for each location, Appendix B

contains a tabulation of the equipment items and locations (the tabulation does not include equipment covered by the evaluation deferment described in Section 2.2.3 of this report),

and Appendix C lists the plant systems identified by the Licensee and the NRC as being essential to safety.

Using the listing of safety-related electrical equipment items,* each equipment item was reviewed by FRC in relation to:

~

NRC DOR Guidelines, as modified by NRC staff interpretations

~

Licensee definition of harsh service environraents (Appendix A)

~

analysis and/or justification of qualification

~

Licensee-proposed remedies for qualification deficiencies.

Topics not within the scope of FRC evaluation are:

~

Based on the FRC conclusion, each equipment item was assigned to one of the generic qualification categories provided by the NRC.

NRC categories are described below.

All equipment item numbers discussed in Section 4 of this report are associated with Reference 68.

The NRC Office of Inspection and Enforcement conducted an on-site verification inspection of selected lE equipment to verify proper installation of equipment, overall interface integrity, location with respect to flood level for equipment inside the containment, and manufacturer's nameplate data.

The manufacturer and model number from the nameplate data were compared to information given in the System Component Evaluation Work Sheets (SCEWS) of the Licensee's report.

S. TECIINICAL EVALUATION

TER-C5417-4 4 ~

TECHNICAL EVALUATION 4.1 METHODOLOGY USED BY THE LICENSEE The Licensee has submitted for Browns Perry Units 1, 2, and 3 a rather voluminous equipment environmental qualification report (20 large volumes in total) dated October 31, 1980, in response to the January 14, 1980 NRC IE Bulletin-79-01B and Memorandum and Order CLI-80-21 dated May 23, 1980.

All previous responses to IE Bulletin 79-01B (April 30 and July 18, 1980) are said to be superseded by this latest submittal.

The final submittal (68] contained a general introductory section which described the Licensee's basic approach to qualification and evaluation methodology.

A review by PRC has generated the following observations and comments.

4.F 1 COMPLETENESS OF EQUIPMENT LIST The Licensee discussed the approach used in selecting the equipment for which qualification must be demonstrated.

For example, the Licensee stated:

~

As directed, TVA has evaluated the environmental qualification of the safety-related electrical components which experience the harsh environment due to Loss of Coolant Accidents (LOCA's) and High Energy Line Break (HELB) accidents.

Only that equipment either required to function for accident mitigation (Category a, as defined in NUREG-0588, Appendix E) or required not to fail (Category b, as defined in NUREG-0588, Appendix E) during accident mitigation, including those required for cold shutdown, are contained in this report.

e The Evaluation Work Sheets (EWS) in Appendix C [68] and their supporting appendices provide documentation of qualification as defined by the DOR Guidelines.

~

Browns Perry Nuclear Emergency Operating Instructions were also used to identify safety functions, safety systems, and components.

~ If a safety-related component's location in the plant was found to be outside the harsh areas, the item was deleted from the equipment list Illl FranMin Research Center ADivision oi The FnsnsSn Insonne 4-1

TERMS 417-4 (although it still is required to be qualified for its nonaccident service environments)

Before an item could be deleted, all associated items, especially cabling, were identified and their locations reviewed against the harsh areas.

This assured that input and output associated with the original item was fully reviewed for qualification.

FRC notes that IE Bulletin 79-01B Supplement 2 requires that qualification documentation for all operating reactors (as of May 23, 1980) be evaluated using the DOR Guidelines.

Nhen sufficient detail is not provided by the DOR Guidelines, NUREG-0588 Category IZ can be used.

1n addition, criteria to be used for.evaluation of replacement components for these plants will be derived using NUREG-0588 Category I.

NUREG-0588 Category I criteria will be applied to documentation associated with reactor facilities whose construction permit safety evaluation reports were issued after July 1, 1974.

For facilities whose construction permits were issued prior to July 1,

1974, NUREG-0588 Category II will be applied.

(NUREG-0588 Categories I and ZZ refer to applicable criteria referenced to ZEEE Standards 323-1974 and 1971<

respectively.)

PRC notes that the DOR Guidelines require the Licensee to review its emergency operating procedures to determine the electrical components needed or relied upon to perform safety functions or provide safety-related display information to the operator.

PRC concludes that the Licensee methodology for identification,of safety-related equipment is consistent with NRC requirements.

4 1 ~ 2 DEFINITION OP EQUIPMENT OPERATING TIME REQUIREMENTS The Licensee has defined the equipment operating time as follows:

Operating time was defined as the time period during which a component must be available to perform its function.

Zt was not considered to be the time actually required to perform an action (i.e., actual time required for a valve to close).

An operating tirae category was defined as specified time period starting at the accident initiation during which a component must be available to perform its function.

This specified time period was given sufficient scope to incorporate all reasonable operating times required for the components in the category.

Jul) 'Franklin Research Center nfl h Orson d The Frank>in Insctutc 4-2

TERMS 417-4 The following operating time categories were used:

W One hour following accident initiation X One day following accident initiation Y Thirty days following accident initiation Z One year following accident initiation W-Z Items marked as "W-Z" are components that fit into operating category A for the first hour following accident initiation and then fit into operating category B for the duration of the event and recovery (taken to be one year for this report).

Isolation valves fall into this situation.

They are required to close and then to remain closed.

X-Z Items marked as "X-Z" are components that fit into operating category A for the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and then fit into operating category B for the year following the accident.

Y-Z Items marked as "Y-Z" are components that fit into operating category A for the first 30 days and then fit into operating category B for the remainder of the year following the accident.

Operating time categories were assigned based upon the review of components'unctions.

For components that perform multiple functions, each function was considered and the worst-case time requirement used for the components.

General functions were defined as having the following operating times categories:

W

& W-Z Primary and secondry containment isolation (including SCIS initiation) folowing a LOCA or HELB inside primary containment; isolation for a HELB outside primary containment (i.e., the specific line that breaks);

scram initiation (RPS),

and scram following a LOCA or HELB inside primary containment or a HELB in the main steam line valve vault.

X a X-Z - Primary and secondary containment isolation for HELB's outside primary containment (except for the line broken);

scram initiation (RPS) and scram for HELB's outside primary containment (except for a main stream line break in the valve vault).

Y a Y-Z - High Pressure ECCS Z - All other functions

!ill Franklin Research Center A DMuon d The FrankSn!nsatutc 4-3

TERM5417-4 PRC EVALUATIONS FRC concludes that the Licensee's approach to operating time is acceptable.

4 1 3 QUALIFIED LIFE The Licensee has not adequately addressed the topic of qualified life for any of the safety-related equipment identified by the, Licensee as essential for safe shutdown of the plant.

The DOR Guidelines required that equipment with components susceptible to degradation caused by thermal or radiation environmental conditions are to have an established qualified life.

The Licensee should maintain detailed maintenance records to demonstrate

that those components which can be degraded are replaced on a scheduled basis in order to restore the equipment and minimize the likelihood of equipment failure to perform a safety-related function.

Qualified life is the maximum period of normal service under specified conditions for which it can be demonstrated that the functional capability of the equipment at the end of the period is still adequate for it to perform its specified safety function for an applicable accident and to remain functional as long as required after the accident.

The qualified life may depend on-carrying out a specificed maintenance program.

The qualified life of some elements of an equipment assembly may be less than the qualified life of the assembly provided a program for replacement of such elements at intervals not exceeding their qualified lifetimes is specified and fulfilled.

The qualified life of.a particular equipment item may be changed during its installed life where justified by new information that permits a reanalysis of the qualification program.

It is necessary to establish a qualified life for every type of safety-related equipment that requires environmental qualification.

A conservative choice of qualified life must be made to account for the assumptions and approximations made in the qualification program.

~

At the time of procurement of the equipment, documented evidence of aging effects was not a requirement;

however, TVA intends to meet the DOR Guidelines in Section 7.0. If the equipment contains material subject to aging degradation (the guidelines require that this determination be made),

an analysis was done to determine the maintenance or change out interval.

When there was insufficient documentation to determine the thermal or radiation aging effects on a piece of equipment, a program of either further analysis of materials (when a detailed list of materials is obtained),

or type testing was instituted.

If neither of these options were available, a replacement or relocation plan was established.

In general, the procureraent specification required equipment whose intended, service, determined either by repairs or replacements, was for the design life of the plant for 40 years; therefore, in our engineering judgment the device will be able to perform its safety function in the interim time period required for completely documenting qualificat:ion.

PRC notes that the salient points of the Licensee's methodology are:

e If equipment contains materials subject to aging degradation an analysis was conducted to determine the maintenance or change out inter va1.

~

When insufficient documentation existed to allow determination of aging effects, an analysis program or type testing was instituted.

~

An equipment replacement or relocation program was established in lieu of analysis or type where appropriate.

~

Procurement specifications required 40 years design life; therefore, the equipment will be able to perform safety functions in this interim period while complete documentation is being completed.

FRC concludes (i) that the procurement specifications requiring a 40-year design life provide absolutely no assurance that the degradation effects due to aging-related s'tresses on equipment have been reduced, accounted for, or eliminated and (ii) that the Licensee's basic approach to aging is acceptable;

however, PRC has found no substantive evidence of the use of the stated methodology and the subsequent Licensee conclusions and action relative to the actual evaluation of the individual equipment items in the EWS data.

TER-C5417-4 4.1.4 LICENSEE EVENT REPORTS (LER)

The Licensee has stated:

Item 6 of the bulletin required that "Licenses Event Reports" (LER) be issued when a component is found not capable of performing its intended safety function.

Section 5.2 of the report orovides a

Summary of Equipment Qualification Status which included the LER number issued when the above determination has been made.

FRC notes, however, that the Licensee has left the LER column blank in Section 5.2 of the report. It is not clear whether there are no LERs or the Licensee has not completed their listing.

4.1.5 LICENSEE'S GENERIC POSITIONS WITH RESPECT TO THE DOR GUIDELINES A.

MARGIN The Licensee states:

In Section 6.0 of the DOR guidelines it is stated that margin only applies to type testing and that the guidelines in Section 4.0 for establishing service conditions include conservatisms which assure margins between the service conditions specificed and the actual conditions which could realistically be expected in a design basis event.

Based upon the above statements and the fact that all calculations for establishing service conditions meet or exceed the DOR Guidelines given in Section 4.0, no additional margin was considered for qualification by analysis.

As stated in DOR Guidelines, Section 6.0, additional margin for the service conditions for type testing needs to be considered only if Section 4.0 and Section 5.2 of the DOR Guidelines are not met; since the guidelines of Section 4.0 are met, margin was considered only if Section 5.2 was not met.

FRC concludes that this position is acceptable.

B ~

ACCURACY The Licensee states:

As stated in Enclosure 3 to IE Bulletin 79-01B, specificed and demonstrated accuracies of all instruments for their trip functions and/or post-accident requirement must be provided.

When the documentation did not clearly demonstrate the specified accuracy during the environmental extremes resulting from a DBE, a program of either further search for documentation that address accuracy or t!II!l Frankiin Research Center A bbnsion ef %he FnuASn Insutute 4-6

TER-C5417-4 type testing was instituted.

In our engineering judgement, the following two statements provide justification for continued operation during the interim time period required to obtain completely documented qualifications:

(1) in general, the procurement specifications required and the vendor's demonstrated accuracies are much more stringent than system requirements, (2) surveillance tests are conducted periodly as required by the technical specifications to confirm the validity of the manufacturer's stated accuracy.

FRC concludes that the Licensee's position is acceptable for interim operation until full qualification can be obtained.

C OPERATING DATA The Licensee states:

Substantial percentages of the systems components installed in plant locations other than inside primary containment, have well established industrial rating at or above the limits required for operation during and/or after the required DBE's.

In cases where operating data is used as a justification for interim qualification.

This qualification will be supplemented at a later date by either type testing and/or further analysis.

If neither of these options are available, a replacement plant was instituted.

FRC notes that NRC required a definitive resolution by November 1980 from the Licensee on all qualification issues.

The Licensee's position is in variance with this requirement.

D RELATIVE HUMIDITY The Licensee states:

The humidity ranges from 30 to 80 percent for areas outside primary containment.

The values given in Section 3.0, Table 1, note E of this report are peak values and probability of occurence is extremely low.

There are redundant fans servicing areas where there is essential equipment.

Most industrial grade electrical equipment can function properly in the reactor zone building ambient humidity.

FRC concludes that this generic position is (i) not clear and (ii) does not alleviate the need for humidity to be addressed by the Licensee as an environmental service condition.

I)II Franklin Research Center A Dtvision of III:nankKn Insole 4-7

TER-C5417-4 E.

TYPE TESTING The Licensee states:

In Section 5.1 of the DOR Guidelines, type testing is preferred but not required for equipment subjected to severe temperature,

pressure, and steam service condition.

However, analysis is acceptable if supported by test data, for the other service conditions.

At the time of equipment procurement, type testing was not a required method of proving qualification.

To the extent that an analysis is not conclusive to verify qualification per the DOR guidelines, a type testing program or a replacement plan was initiated.

TVA will provide justification for the interim operation until adequate qualification information is available to meet the DOR Guidelines.

FRC notes that the DOR Guidelines state:

Type Testing is the preferred method of qualification for electrical equipment located inside containment required to mitigate the consequences of design basis events, i.e., Class IE equipment (see Section 3.0 above).

As a minimum, the qualification for severe temperature,

pressure, and steara service conditions for Class IE equipment should be based on type testing.

Qualification for other service conditions such as radiation and chemical sprays may be by analysis (evalaution) supported by test data.

FRC concludes that type testing is required, and that the Licensee's generic position regarding analysis and fux'ther search for qualification documentation is not in accordance with NRC requirements.

F. RADIATION The Licensee states:

~

Beta Radiation According to Section 4.1 of the DOR Guidelines, beta radiation has low penetrating power in comparison to gamma rays of equivalent energy.

Of the genexal classes of electrical equipment in the plant containment (e.g., cables, instrument transmitters, valve operators, containment penetrations) r electrical cable is considered the most vulnex'able to damage from beta radiation.

For other equipment whose enclosure provides adequat:e shielding, beta radiation need not be considered.

For any equipment that is determined unshielded (e.g., cable) or is shielded by sheet metal of 20 gauge or less, an analysis of the qualification of the equipment related to beta radiation was included as attachments to the EWS's.

09 Franklin Research Center h Oinrion of The Frenkffn fnseerre 4-8

TER-C5417-4

~

Gamma Radiation - From Table C-1 in Appendix C in the DOR Guidelines and reference 1 and 2 below, there is substantial test data available to demonstrate that most conventional material used in electrical equipment has a gamma radiation threshold exceeding 10 rads; the exception is solid-state devices containing N-MOS integrated circuits which have a threshold of 10 rads (see Table C-1).

Teflon has a threshold for'amage of approximately 3.5 x 10 rads (for 20 percent decreases in elongation).

Electrical properties (e.g., resistivity) of these materials are sufficiently conserative initially, such that substantial changes can be tolerated without causing equipment failures or malfunction.

Threshold is defined from the above referenced table as the radiation exposure required to change at least one physical property of the material.

The threshold is not a point of failure or end of useful life, therefore, there is a band of tolerance from the threshold point to the failure point which may vary by an order of magnitude or more.

On the above basis and the existing test data, it is not considered necessary to perform qualifications test or analysis on electrical equipment for radiation of less than 104 rads which degrade the safety function of the equipment.

FRC agrees with the Licensee's position.

4. l. 6 REQUIRED SIGNATURES The Licensee has stated:

~

To ensure completeness and accuracy of the EWS signatures of a

preparer, reviewer, and quality assurance engineer are required on each of the EWS.

Any appendixes for which the preparer or reviewer of EWS was not directly responsible will also contain preparer and reviewer signatures.

~

The most significant changes to the EWS were as follows:

1) use of appendixes, 2) use of permanent

notes,

3) required signatures, and 4) use of unique numbering system for the EWS and their appendixes.

FRC notes that none of the sheets appears to be signed by a quality assurance engineer.

TERM5417-4 4.1.7 CHEMICAL SPRAY The Licensee states:

Chemical spray is not applicable for this report since no chemical injection is used.

(This is a permanent note N/A on all EWS sheets.)

FRC notes that the DOR Guidelines require demineralized water sprays to be addressed.

In addition, the effects of in-leakage must be considered.

The Licensee has not complied with this requirement.

4.1,8 DESCRIPTION OF QUALIFICATION/REPLACEMENTPLAN The Licensee states:

It is TVA's intention to comply fully with the requirements of Bulletin 79-01B.

This section addresses the requirements stated in item 4 of the bulletin for "outstanding items." It is not possible to submit a

detailed qualification/replacement plan at this time.

The following items have a great impact on our inability to supply a

detailed schedule at this time:

a.

Limitations on industry's capability for testing large numbers of components.

b.

Availability of qualified replacement equipment.

c.

Unit outage schedules.

TVA has a contract with Wyle Laboratories to do any testing that is required to prove qualification of any questionable equipment.

Wyle will also provide TVA a detailed schedule of all tests they plan to conduct for TVA.

When we receive schedules of testing from Wyle Lab, we will inform the NRC as stated in your letter dated October 1, 1980, from D. G. Eisenhut to licensees of operating plants.

TVA will make a best faith effort to test equipment as soon as possible.

However, if problems are encountered with either the testing or qualificability of the equipment, the justification for continued operation will be reviewed as well as a

safety review.

Zt is our plan to schedule first the items that have the greatest impact on safety.

The qualification status of all equipment is listed in Table 5.2.

The status of all items falls into one of four categories as listed below.

(ill Franklin Research Center h Divan d The Fission Inseam 4-10

TER-C5417-4 Category I - Components qualified to DOR guidelines.

Category II - Components for which analysis indicating qualification but that lack documentation to prove qualification to DOR quidelines.

Category III-Items that will be qualified by either analysis or type testing or a combination of these methods.

Category IV Equipment to be replaced.

For Category IV equipment checks were made to determine the availability of qualified equipment on the market.

In general, even if qualified equipment is available the delivery has a long and indefinite lead time.

TVA will submit a detailed schedule for qualifying or replacing all open items by February 1, 1981.

This schedule will be developed in conjunction with Wyle Labs.

FRC concludes that the Licensee has not complied with the NRC requirement that the Licensee must submit all qualification information to NRC by November 1, 1980.

With this information, an exact schedule for equipment replacement and specific justification for interim operation must be provided for any item which does not conform to Guidelines requirements.

5. CONCLUSIONS

TER-C5417-4 5~

CONCLUSIONS FRC's review of the qualification documentation and other information submitted by the Tennessee Valley Authority for these equipment items and their applications in the Browns Ferry Unit 1 plant has resulted in the following categories:

NRC catecaoCrr Z.a Compliance With The DOR Guideline Re uirements Equipment Fully Satisfies All Applicable Requirements for Life of the Plant Quantity Of Ecrui ment Items 1.b Equipment Does Not Meet All Applicable Requirements for Life of the Plant;

However, Deviations are Judged Acceptable ZI,a Equipment Fully Satisfies All Applicable Requirements for Less Than Plant Life IZ.b Equipment Fully Satisfies All Applicable Requirements Provided That Specific Modifications are Made ZI.c Equipment for Which the Licensee Has Not Provided Evidence of Full Compli-ance with the Guidelines, but which is Judged by FRC To Be Satisfactory for Less Than Plant Life Based on Total EEQ Program Review IIZ Equipment is Exempt from Qualification ZV.a Equipment has Qualification Testing Scheduled IV.b Equipment has High Likelihood of Operability; However, Proper Qualification Documentation is Not Available 79 Equipment is Unqualified VI Equipment for Which Qualification is Deferred l (ll Franklin Research Center 5-1 A Divoion ot The Franklin huuetc 56

TERM5417-4 In gen'eral, the major deficiencies that have been identified are shown in the summary review sheets at the end of= the section.

The conclusions stated herein represent a summary of the results of the equipment environmental qualification evaluation conducted by FRC in accordance with the methodology presented in Section 3.

The evaluation results are largely based on the available qualification documentation provided by the Licensee.

The results of the review do not necessarily imply that the equipment is unreliable,

unsafe, or represents a significant plant safety issue; they do imply, however, that qualification documentation is inadequate and that additional information is required.

The Equipment Environmental Qualification Summary Form presented on the following pages shows the overall results of the PRC review.

The entries on this. form delineate the overall status of each specific equipment item with respect to compliance with the Guideline criteria defined in Section 2.0 and the resultant qualification categories defined in Section 3.0.

The following designations are used:

A deficiency with respect to compliance with a Guideline requirement.

Deficiencies result in equipment items categorized as unqualified or qualification not established.

L ~ A limiting condition with respect to qualification in that the qualified life has not been established by the Licensee.

0 NRC Qualification Category.

R ~ Replacement of the equipment by the Licensee is planned.

TER-C5417-4 With respect to environmental service conditions, the Licensee has statedt A. Service Conditions The environmental conditions present in plant areas that can affect safety-related equipment have been established. The following categories were used to bound anticipated plant conditions.

1. Normal The temperature,

pressure, humidity, and radiation ranges that are expected to be present when the plant is in any of the technical specification modes of operation.

2. Abnormal-Conditions that could exist for all areas for a short period of time that may occur once or more a year.

3. Accident-Environmental conditions that would be experienced as a

result of high energy pipe breaks outside containment, or a large, intermediate or small LOCA or main stream line break inside containment. All analyses performed to determine the service conditions were performed consistent with the guidelines of IE Bulletin 79-01B and NUREG-0588 and in accordance with either TVA quality assurance procedure EP 3.03 or General Electric's internal quality assurance program. B. Temperature and Pressure Inside Containment The controlling breaks for the pressure response of the drywell and wetwell and the temperature response of the wetwell are the large LOCA Design Basis Accident'DBA) and the Intermediate Break Accident (IBA). The DBA and a 0.5 ft steam leak produce the most severe temperature transient in the drywell. The containment pressure and temperature response for all breaks were evaluated by the methods discussed in General Electric Report No. NEDO-20533, June 1974. Mass and energy releases were calculated using the methods also discussed in the above General Electric report. Details of the analyses are provided in PSAR, section 14 and General Electric Report NEDO-24580. 0(l Franklin Research Center h DivlSiOn ct The Fronton tnsututc A-54

TER-C5417-4 C. Outside Containment High Energy Line Breaks Plant areas outside containment were reviewed to determine areas where high energy piping was located and could potentially produce effects that would impact safety-related equipment. The areas affected by high energy line breaks are the reactor building and the main steam valve vaults. Reactor Building The high energy lines located in the reactor building are: (1) High Pressure Coolant Injection (HPCI) steam supply to the pump turbine 547 F, 1020 psia, quality - 1. (2) Reactor Core Isolation Cooling (RCIC) supply to the RCIC pump turbine 547'F, 1020 psia, quality - l. (3) Reactor Water Cleanup (RECU) system - 547'F, 1020 psia, quality - 0. r Single-ended circumferential ruptures at the fluid conditions listed above were postulated. Mass and energy releases for all steam supply lines except one break of the RWCU were generated using the Moody critical flow correlation assuming an fL/D equal to zero. Upstream pressure and temperature, and therefore mass flow rates, were assumed to remain constant until the line was isolated. These steam supply lines isolate automatically on high temperature in the reactor building.. Temperature sensors are located in the vicinity of the line to assure rapid detection and isolation. Isolation times include signal process

time, valve stroke time, and break detection time.

The sensors used are redundant, class lE, and electrically trained. Mass and energy release of the remaining RWCU break was generated using the RETRAN computer code. Only this break requires operator action for isolation. Isolation was assumed to occur 10 minutes after the break. Detection is based on high fluid temperature at the discharge of the nonregenerative heat exchangers. The steam valve vault was modeled using three nodes and were input into the COMPARE-MOD1 computer code. No heat sinks were considered. ~ 00 Franklin Research Center ADI4sen or 1he Fcsnk5n Insatu(c A-55

TER-C5417-4 The valve vaults at Browns Ferry were constructed with large blowout panels to provide pressure relief to the turbine building in the event of a pipe break. These paths were included in the model. 2. Radiation Environment The radiation environments inside the drywell and in the reactor building after a design basis LOCA were calculated consistent with the requirements of IE Bulletin 79-01B and NUREG-0588. Initial airborne sources in the drywell were calculated assuming an instantaneous release of 100 percent of the core inventory of iodine. Transfer of iodine from the drywell free volume to the water in the torus was conservatively calculated as a function of time until the airborne concentration was reduced by a factor of 200 (considered to be at equilibrium). Sources in the water in the torus were calculated assuming an instantaneous release, of 1 percent of the core inventory of the solid fission products and the iodine transferred from the drywell. Airborne activity in the reactor building was calculated based on a design basis leak rate from the primary containment and design flow of the SGTs. Source terms were calculated at various time after an accident allowing for decay and dose rates were calculated with a point-kernel-with-buildup computer code. Radiation exposures in the reactor building due to recirculation of the torus water through the RHR and containment spray-systems were also calculated. These dose rates were then integrated over the duration of the accident. 3 ~ Main Steam Valve Vaults The high energy lines in the valve vaults are the main steam lines and the main feedwater lines. Breaks in the main steam line are controlled from an environmental standpoint due to the large line size and the high energy associated with the steam. Conditions of the main steam are 550'F, 1050 psia, quality l. A double-ended rupture of the main steam coincident with a break of the 4-inch RCIC steam line was evaluated. Mass and energy releases were provided by General Electric. Break flow was terminated by isolation of the main steam lines based on signals from safety-related sensors. Il(l Franklin Research Center A Division of riie Frenkbn Inseosie p;56

TER-C5417-4 4 ~ Operation Environmental Conditions An environmental listing of service conditions are tabulated in Table 1. The service conditions considered were pressure, temperature, humidity, and radiation. Normal and abnormal space ambient temperatures for nonaccident conditions were obtained from information used in the initial design phase of the plant in conjunction with data accumulated at the plant site in various spaces, for all units, under extreme outside temperature conditions (100'F outside atmosphere). Pressures and temperatures for accident conditions were obtained from transient curves and analysis which studied the effects of a LOCA on reactor zone spaces. Environmental service and conditions were only considered in the reactor, zone and primary containment. The control bay and electrical board room were not considered since their atmospheres did not interface with the reactor zone environment. The environmental table of service conditions was developed for various plant conditions including the following: normal average day, abnormal cohditions (outside temperature 96-100'nd maximum river water temperature exists), LOCA/HELB inside primary containment, HELB outside primary containment, and tornado (sudden pressure drop by 3 pounds per square inch).
