Situated in the Gifford Pinchot National Forest amidst Washington's Cascade Mountain range, the Supply System's Packwood Lake Hydroelectric Project this year celebrated 30 years of economic, reliable electricity generation.

Dry weather conditions and lower than average water flow into Packwood Lake this year were less of a cause for celebration for the Supply System's first operating power plant. Packwood's generation during fiscal year 1994 totalled 65,600 megawatt-hours.

Although a year with normal precipitation results in Packwood generating about 84,000 megawatt-hours, high water years have seen production rise to more than 100,000 megawatt-hours.

Only four full-time employees have been sta-tioned at the Packwood Project since it went into operation in 1964. While the plant is designed to operate in a somewhat automatic mode, operators with knowledge and experience in electrical, mechani-cal, instrumentation and power plant operations are required to assure continued safe and reliable opera-tions. Any major repair work is typically scheduled for October each year, when the Project is shut down for its annual maintenance outage.

Among the various maintenance activities com-pleted during this year's outage, Packwood staff repainted the 191-foot-tall surge tank which accepts water from Packwood Lake as it is channeled through two tunnels and around a mountain in a 22,000-foot pipeline.

Electrical energy from the Packwood Project is distributed by the Bonneville Power Administration (BPA) for use by 12 Public Utility Districts (PUDs) in Washington state. Packwood supplies enough electricity to meet the annual needs of nearly 4,000 Pacific Northwest residences.

In addition to low-cost electricity, the utilities that are participants in the project receive funds each fall when revenues gained from the Packwood Project exceed costs. This year, more than $ 1 million in revenue was distributed to Packwood participants under power sales contracts based on member purchasers'ower allocation shares.

The Supply System entered into Plant 2's 10th annual refueling and maintenance outage with a com-prehensive and highly detailed plan for completing the large volume of work required to prepare the power plant for another successful operating cycle. Early into the outage, a problem with a number of electrical modules in the plant's containment building caused outage workers to devote considerable time and atten-tion to test and replace a significant number of modules.

Although much time and attention was devoted to this issue, Supply System staff worked hard to minimize its impact on other critical work tasks. The electrical module problem was estimated to add about 18 days onto the original 60-day outage schedule.

Extra time also was needed for plant staff and outage workers to resolve several other issues that arose during the outage's extensive maintenance and inspec-tion activities. The unplanned work involved detailed analysis of a crack detected in one of the jet pump sensing lines, which serves to maintain accurate mea-surements of reactor coolant flow; the overhaul of control rod mechanisms; repair of two valves in the reactor shutdown cooling system; and replacement of dozens of aged electrical relays. The additional outage tasks delayed Plant 2 restart activities until July 26 three weeks beyond schedule.

While challenged with unexpected work activity, plant staff remained committed to successfully com-pleting the work originally scheduled to ready the plant for safe, reliable operation. Among the outage work accomplished this year was the replacement of 156 of the reactor plant's 764 nuclear fuel assemblies; the inspection of the reactor vessel and associated piping systems; work on the plant's 20 jet pumps, which are used to sustain reactor coolant flow; replacement of several valves in containment used to control atmospheric conditions; and inspection of the main electrical generator.

The individuals involved in outage work activity each demonstrated a sense of dedication and the ability to work as a team toward a common goal. That goal is to improve Plant 2 performance and reliability to the point that it routinely will operate continuously from the end of one annual outage to the beginning of the next one. By doing so, the region's ratepayers will receive the best possible return on their investment in Plant 2.

New Plant 2 Sinnrlator After years of working to develop a highly accurate training tool for Plant 2 reactor opera-tors, the Supply System this year received its new Plant 2 simulator. Designed as a full-scale, computerized replica of the Plant2control room, the new simulator accurately mimics plant con-ditions and enables reactor operators to get hands-on training in an environment that duplicates the appearance and operation of the actual Plant 2 control room instrumentation.

The simulator replaces Plant 2's original simulator, which in 1988 was determined to need improvement tomeetincreasinghighstan-dards of performance required by the Nuclear Regulatory Commission (NRC) for training and examining reactor operators throughout the nuclear industry.

accounting prin'ciples used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our au'dits.provide a reasonable. basis for our opinion.

In our opinion, s'uch financial statements present fairly, in all material respects,;the financial position .

of the Supply System's individual projects at June 30; 1994, and the results of their operations and chsh flows

. for the year then ended in 'conformity with gen'erally accepted accounting principles.

.'s discussed-in Note F to the financial. statements, NucleapPr6jects.Nos'. 1'and 3'are involved-in

'isputes concerning costs shared with Nuclear Projects Nos. 4 and 5. The ultimate amount of Additional costs,,

ifany, to be borne by Nuclear Projects Nos. 1 and 3 due to this'matter is presently indete'rminable. As further

'iscussed in Notes A and F, the Supply System's'Board has authorized the terminatiop of Nuclear Projects.

Nos. 1 and 3 and the ultimate utilization of these projects is uncertain.

)I 1 Executive Board Chairman Louis H. Winnard Chief Executive Officer J.V. Parrish After four decades of doing business as the Washington Public Power Supply System, sometimes marked by turbulence and turmoil, we are ready to enter the new millennium with a new name: Energy Northwest. This change signifies the end of one era of our journey,and the beginning of a new one in our pursuit of excellence.

We are not fleeing from our past. Rather, we are running toward our future.

Five years ago our journey almost ended prematurely. Plant 2, our sole operating nuclear generating station, was over staffed, overpriced, and under-productive. The cost of power was too high, at 3.34 cents per kilowatt-hour, to be competitive. The plant was unreliable, worker radiation exposure was too high,and our staff was wasting far too much time trying to keep the plant running, rather than operating it reliably. We were faced with a clear choice: cut costs and increase reliability, or terminate the plant.

Here is what has been accomplished since 1995: We generate about 10 percent of Bonneville's firm power, and provide the federal agency with the

Customers that a Reducing the price of power is still a key goal (the few years ago were scrambling to abandon BPA fiscal 2000 target is 2.15 cents a kilowatt-hour), but now are competing fiercely for their share of low-increased generation is the principle tool we will cost BPA power.

OPERATIONAL HIGHLIGHTS Energy Northwestis on ajourney; ajourney to excellence that began in 1995 when the cost ofpower from Plant 2 was not competitive at 3.34 cents a kilowatt-hour.

By reducing costs andincreasing reliability, Plant 2 delivered electricity to the Bonneville Power Adminis-tration in fiscal year 1999 at a price 2.26 cents a kilowatt-hour thatis competitive with other available resources.

than a cent per kilowatt-hour. Moving to a 24-month fuel cycle is expected to save between $ 100 million and $ 'I20 million over the life of Plant 2. The transition will cost about $ 22 million but, if Plant 2 skips an outage every other spring, the yearly average price for its power is likely to drop because the plant will generate more electricity over the two-year period. And, by skipping every other outage, Plant 2 will save about

$ 15 million for each one missed.

Another initiative that is expected to help reduce the cost of power from Plant 2 is a plan to From left: partner with the Omaha Public Power District (OPPD) to establish a service company that will use shared resources to provide centralized support functions to Plant 2 and OPPD's Fort Calhoun Station.

Then it made sense to have Plant 2 off line and Plant 2 has come a long way in its pursuit of refueling. The plant simply couldn't compete with excellence. It has developed into a valued resource hydropower during the spring runoff. that is a counterpoint to the Pacific Northwest's The situation is different now, for three reasons. traditional reliance on low-cost hydroelectric First, efforts to restore runs of endangered salmon dams.

Y2Kreadiness certified Energy Northwest certified to the Nuclear Regula-tory Commission on July 1 that Plant 2is ready to meet the new millennium without plant safety and reliabilityconcerns.

Tests at Plant 2, confirmed byindustry testing, showed that nuclear plant safety systems are not date-driven and willnot be compromised by Y2K computerissues. No nuclear facilityin the nation has found a Y2Kproblem that would prevent operation or keep safety systems from safely shutting down the plant and maintainingitin a safe condition.

A Nuclear Regulatory Commission audit team visited Plant 2in January and came away impressed with preparations for anyissues the year 2000 may pose.

MANAGEMENTREPORT ON RESPONSIBILITY FOR FINANCIALREPORTING The management of Energy Northwest is responsible for preparing the accompanying financial statements and for their integrity. The statements were prepared in accordance with generally accepted accounting principles applied on a consistent basis, and include amounts that are based on management's best estimates and judgments.

The financial statements have been audited by PricewaterhouseCoopers LLP, Energy Northwest's independent accountants. Management has made available to PricewaterhouseCoopers LLP all financial records and related data, and believes that all representations made to PricewaterhouseCoopers LLP during its audit were valid and appropriate.

Management has established and maintains internal control procedures that provide reasonable assurance as to the integrity and reliability of the financial statements, the protection of assets from unauthorized use or disposition, and the prevention and detection of fraudulent financial reporting. These control procedures provide for appropriate division of responsibility and are documented by written policies and procedures.

Energy Northwest maintains an ongoing internal auditing program that provides for independent assessment of the effectiveness of internal controls, and for recommendations of possible improvements thereto. In addition, PricewaterhouseCoopers LLP has considered the internal control structure in order to determine their auditing proce-dures for the purpose of expressing an opinion on the financial statements. Management has considered recommenda-tions made by the internal auditor and PricewaterhouseCoopers LLP concerning the control procedures and has taken appropriate action to respond to the recommendations. Management believes that, as of June 30, 1999, internal control procedures are adequate.

Chief Financial Officer AUDIT, LEGALAND FINANCE COMMITTEE CHAIRMAN'SLETTER The Executive Board's Audit, Legal and Finance Committee is composed of five independent directors. Mem-bers of the Committee are John F. Cockburn, Chairman; Rudi Bertschi; Vera Claussen; Roger Sparks; and Louis Winnard, Ex Officio. The Committee held 12 meetings during the fiscal year ended June 30, 1999.

The Committee oversees Energy Northwest's financial reporting process on behalf of the Executive Board. In fulfillingits responsibility, the Committee discussed with the internal auditor and the independent accountants, the over-all scope and specific plans for their respective audits, and reviewed Energy Northwest's financial statements and the adequacy of Energy Northwest's internal controls.

The Committee met regularly with Energy Northwest's internal auditor and independent accountants to discuss the results of their examinations, their evaluations of Energy Northwest's internal controls, and the overall quality of Energy Northwest's financial reporting. The meetings were designed to facilitate any private communication with the Committee desired by the internal auditor or independent accountants.

John . Cockburn Chairman, Audit, Legal and Finance Committee 14

. Report of Independent Accountants To the Executive Board of Energy Northwest In our opinion, the accompanying individual balance sheets and related statements of operations and comprehensive income and of cash flows present fairly, in all material respects, the financial position of Energy Northwest Nuclear Project No. 1, Nuclear Project No. 2, Nuclear Project No. 3 and Packwood Hydroelectric Project at June 30, 1999, and the results of each of their operations and each of their cash flows for the year then ended in conformity with generally accepted accounting principles. These financial statements are the responsibility of Energy Northwest's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with generally accepted auditing standards, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assess-ing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above.

The Year 2000 inforination, shown as required supplementary information on page 35, is not a required part of the basic financial statements but is supplementary information required under Technical Bulletin 98-1, as amended, issued by the Governmental Accounting Standards Board, and we did not audit and do not express an opinion on such information. Further, we were unable to apply to the information certain procedures prescribed by professional standards because the disclosure criteria specified by Technical Bulletin 98-1, as amended, are not sufficiently specific and, therefore, preclude the prescribed procedures from providing meaningful results. In addition, we do not provide assurance that the Projects are or will become year 2000 compliant, that the Projects'ear 2000 remediation efforts will be successful in whole or in part, or that parties with which the Projects do business are or will become year 2000 compliant.

six months before the millennial deadline. This effort con-sumed the effort of at least 16 men and women for a year and a half - as well as costing Energy Northwest $ 17.6 million.

Energy Northwest first addressed year 2000 issues in 1996, when replacement and upgrading major business computer and software programs began. In January of last year the Year 2000 Project was formally launched - an examina-tion of all computer systems and software programs used in and around Plant 2. More that 2,200 embedded sys-tems were identified. Some were not time or calendar sen-sitive, and hence left alone. Some were easily fixed. Many were replaced. No computer or software problems have been found that would have presented nuclear safety is-sues problems that would have incapacitated emergency systems or prevented continued operation of the plant.

In May 1998, the Nuclear Regulatory Commission issued a letter to all commercial nuclear plants, ordering that they establish year 2000 programs and report in writing by July 1 of this year. Energy Northwest reported by the deadline that Plant 2 was ready for the year 2000.

Contingency plans were prepared. External risks have been identified and a multi-discipline team formed to ad-dress them. Examples of contingency plans include stock-piling consumables such as diesel fuel for emergency generators in case there are potential supplier disrup-tions. There will also be extra staffing during sensitive time periods.

As for the actual move into the year 2000, suggestions from the Western Systems Coordinating Council, which recommends standards for an electrical grid covering 14 western states and two provinces, have been followed.

Plant 2 will be at 80 percent power as the clock ticks to-ward midnight. This posture has been communicated to Bonneville for integration into the Western Systems Co-ordinating Council's contingency plan. At 80 percent, Plant 2 will be in a position to rapidly increase power in case there is a problem with other generating stations or 35

1 INTRODUCTION AND GENERAL DESCRIPTION

1. 1 Introduction In March 1982, the Nuclear Regulatory Commission staff (hereinafter referred to as the NRC staff) issued its Safety Evaluation Report (NUREG-0892) regarding the application by the Washington Public Power Supply System (hereinafter=referred to as the applicant or WPPSS) for a license to operate the Washington Public Power Supply System Nuclear Project Number 2 (hereinafter referred to as WNP-2 or facility), Docket 50-397. The NRC staff Safety Evaluation Report (SER) on WNP-2 was issued in March 1982. Supplement No. 1 (SSER 1) to the SER was issued in August 1982 and included the staff evaluation of the WNP-2 geology and seis-mology. SSER 2, which was issued in December 1982, addressed several outstand-ing licensing issues as well as the report of the Advisory Committee on Reactor Safeguards (ACRS) to the Chairman of the NRC on the WNP-2 operating license (OL) application. This report is Supplement No. 3 to the Safety Evaluation Report.

The purpose of this supplement is to provide the results of the NRC staff's review of additional information submitted by the applicant in regard to outstanding issues identified in Sections 1.7, 1.8, and 1.9 of SSER 2.

Each section of this supplement is numbered and titled to correspond to the sections of the SER and the supplements that have been affected by the NRC staff's additional evaluation and, except where specifically noted, does not replace the corresponding'ection of those documents. Appendix A is a continuation of the safety review chronology and lists additional documents used in this supplement. Appendix B is an updated bibliography. Appendix E is a list of principal contributors to this supplement.

Copies of this SER supplement are available for inspection at the NRC Public Document Room, 1717 H Street, NW, Washington, D. C., and at the Richland City Library, Swift and Northgate Streets, Richland, Washington. Single copies may be purchased from the sources indicated on the inside front cover.

The NRC Project Manager assigned to the operating license application for WNP-2 is Dr. Rajender Auluck. Dr. Auluck may be contacted by calling (301) 492-9778 or writing:

2. 5. 1. 3. 1 Ashfal 1 In the SER-OL, Supplement No. 1 (SSER-1) Appendix G, the staff and the United States Geological Survey (USGS) indicated that the FSAR estimates of the uncompacted thickness of ashfall and the rate of fall fell short of more recently developed estimates by the USGS based on experience with the May 18, 1980 Mt. St. Helens eruption. In accordance with the Standard Review Plan (SRP)

(NUREG-0800), Section 2.5. 1, concerning operating license reviews, all new infor-mation on the regional and site geology developed after issuance of the construc-tion permit (CP) SER must be included and evaluated in the determination of site suitability and design criteria. The applicant, therefore, was asked to evaluate the ashfall considerations discussed in the following paragraphs.

Although the compacted design thickness chosen (7.4 cm or 3 inches) was con-sidered conservative, the uncompacted thickness was based on earlier estimates of 20% to 40% compaction of loose ash. As was pointed out by the USGS (SSER-l, page G-ll), a compaction factor of up to 75% was measured for the May 18, 1980 Mt. St. Helens eruption. Although the validity of this latter figure had not been determined when SSER-1 was written, it was considered prudent to use a more conservative estimate than 20%%u'o 40% -somewhere between 50%%u'o 60%. This higher estimate would result in a maximum of 18.5 cm (7.4 inches) of loose ash.

The rate of ashfall for a 20-hour period, based on the earlier FSAR percent compaction estimates of 0.37 cm/hr (0. 15 inch/hr) would result from the compacted thickness of 7.4 cm (3 inches). Therefore a higher rate based on the more recent uncompacted ash estimates was suggested, the average being 0.92 cm/hr (0.36 inch/hr) and the maximum l. 1 cm/hr (0.44 inch/hr) for the Katmai volcano rate.

Based on these differences between the applicant's estimates on the one hand, and those of the NRC staff and the USGS on the other, the applicant committed to set up a task force to evaluate and recommend a plan to incorporate the new information.

In a letter dated October 4, 1982, the applicant evaluated the WNP-2 plant sys-tems and equipment with regard to operability and reliability during a design-basis ashfall. The more conservative values of maximum compacted (3-inch) and uncompacted (7.4-inch) ashfall thicknesses and the average and maximum rates (0.35 inch/hr and 0.44 inch/hour, respectively) were used, coincident with loss of offsite power for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. As a result of this analysis, the applicant proposed several plant procedures and equipment modifications to ensure that the WNP-2 SSER 3 2-1

plant could operate safely and achieve safe shutdown following a desi'gn-basis ashfall.

The NRC staff has reviewed the submittal and concludes that the applicant has adequately addressed the consequences of the volcanic event and that the proposed plant procedures and equipment modifications will provide adequate assurance of safe plant operation and shutdown 'following such an event. This resolves con-firmatory item 24.

.reflect a more complete analysis. The applicant provided the revised analysis by Amendment 27 to the FSAR. The revised analysis included air accumulators and gas bottles as potential missile sources.

The primary means of providing protection to safety-related equipment from damage resulting from internally generated missiles is through the plant physical arrangement. Safety-related systems are physically separated from nonsafety-related systems, and redundant components of safety-related systems are physically separated so that potential missiles could not damage both trains of safety-related equipment. Stored spent fuel is protected from damage by internally generated missiles by the fuel pool walls and by pre-venting the location of high-energy piping systems or rotating machinery in the vicinity of new or spent fuel.

The applicant provided an evaluation of potential missile sources on the basis that a single failure could result in their becoming potential missiles. The evaluation indicated that there were no credible potential missile sources, including air accumulators and gas bottles, that could cause adverse effects on safety-related systems and components, except for the motor-generator set.

The applicant has installed a barrier that the NRC staff considers adequate to prevent any internally generated missile from the motor-generator set from damaging the nearby safety-related cables and cabinets. The staff reviewed the applicant's assumptions and evaluation for potential missiles outside contain-ment and agrees with the conclusion that adequate protection is provided.

the above, the NRC staff concludes that the design of the facility is Based on in conformance with the requirements of General Design Criterion (GDC) 4 as it relates to protection against internally generated missiles and is, therefore, acceptable with respect to internally generated missiles outside containment.

The design of the facility for providing protection from such internally generated missiles meets the applicable acceptance criteria of SRP 3.5. l. 1.

(NUREG-0800).

3. 5. 1. 2 Internally Generated Missiles (Inside Containment)

In the SER, the NRC staff noted that the applicant's analysis of potential missiles and the effects of the internally generated missiles was not complete.

The applicant has provided a revised analysis by Amendment 27 to the FSAR. The E

NNP-2 SSER 3 3-1

revised analysis includes missile characteristics, trajectory, and impact area, as applicable. The NRC staff has reviewed the results of the applicant's missile analysis for internally generated missiles inside containment and agrees with the conclusion that unacceptable damage to safety-related equipment will not occur; thus the requirements of GDC 4 are satisfied with respect to such missiles.

The staff has reviewed the adequacy of the applicant's design to maintain the capability for a safe plant shutdown and to prevent unacceptable radiological release in the event of internally generated missiles inside containment.

Based on the above, the staff concludes that the design is in conformance with the requirements of GDC 4 as it relates to protection against internally gen-

"erated missiles inside containment; therefore, this aspect of the plant s design is acceptable. The design of the facility for providing protection from internally generated missiles meets the applicable acceptance criteria of SRP 3.5. 1.2 (NUREG-0800). This finding, together with the finding in Sec-tion 3.5. 1. 1 above, resolves outstanding issue 2.

3.5.2 Structures, Systems, and Components To Be Protected from Externally Generated Missiles In the SER, the staff stated that except for the diesel generator exhausts, the safety-related structures, systems, and components were acceptably protec-ted from tornado missiles. Regarding the diesel generator exhausts, the NRC staff was concerned that the diesel exhaust openings of one of the two engineered safety feature (ESF) diesels might be blocked by tornado-borne missiles (e. g., utility poles). Each ESF diesel has two exhaust openings. The applicant stated that, with one diesel exhaust opening blocked, the correspond-ing diesel would not accept its required load. Assuming a single failure in the redundant diesel (failure to start), neither diesel would be available in the case of a loss of offsite power resulting from a tornado.

As guidance in evaluating the site for the source(s) of such missiles, the NRC staff used SRP 3.5. 1.4 (NUREG-0800), which states that a utility pole should be considered as a missile source at elevations up to 30 feet above all grade levels within 1/2 mile of the facility structure. For this plant, the exhaust openings are more than 30 feet above grade; however, there is a bluff due south of the diesel generator building. The NRC staff was concerned that this area might be used as a lay down area and that utility poles or other con-struction materials might be stored there.

The NRC staff recommended that the applicant provide administrative control over the bluff. In a submittal dated July 23, 1982, the applicant stated that it was extremely improbable that a tornado would lift a utility pole and trans-port it to the diesel generator building. The applicant provided a limited probabi listic risk assessment (PRA) to support this statement that indicates that the probability of a tornado generating a utility pole missile that would plug one of the ESF diesel generator exhausts at the same time the redundant diesel ~enerator would fail to start from an independent cause is on the order of 10-~ per year.

The NRC staff has reviewed the applicant's PRA. Based on this NRC staff review, and on the NRC staff's independent determination of the tornado fre-quency at the WNP-2 site, the staff finds that the probability of a utility WNP-2 SSER 3 3-2

pole missile plugging one diesel generator exhaust at the same time the second diesel generator fails to start is very low. The NRC staff has also examined the site terrain and concludes that the possible sources of missiles are limited. Further, between the bluff and the diesel exhausts are six forced draft cooling towers and a pumphouse. A utility pole lifted from the bluff would have to traverse a very limited path between the intervening cooling towers to reach the- diesel exhaust openings. The NRC staff, therefore, con-cludes, based on the low probability, that there is reasonable assurance that missiles resulting from a tornado will not prove to be a danger to the diesel generator exhausts. The NRC staff concludes that conformance to the require-ments of GDC 4 has been demonstrated in that, through the use of probabilistic risk assessment, there is'easonable assurance that tornado missiles will not endanger the diesel generator exhausts, and, therefore, the risk to the public is acceptable. This resolves outstanding issue 3.

3.9 Mechanical S stems and Com onents 3.9.3 ASME Code Class 1, 2, and 3 Components, Component Supports, and Core Support Structures 3.9.3. 1 Loading Combinations, Design Transients, and Stress Limits In SER Section 3.9.3. 1, the NRC staff stated that the applicant committed to demonstrate that a square root of the sum of the squareF-(SRSS) combination of dynamic responses for WNP-2 achieves the 84%%u'onexceedence probability level.

The staff has reviewed the information in the following referenced documents:

Bouchey, 1983; Bouchey, 1982a; GE SMA 12109.01-R001; and NEDE-24010-P (see Appendix B). In Bouchey, 1983, the applicant performed a study that included 96 samples of combinations of dynamic responses resulting from safety/relief valve (SRV) discharge and seismic loadings. ,The results of the study indicated that the nonexceedence probabilities (NEPs) of SRSS combination of responses at selected sample locations are at or exceed 50K, and the NEPs of 1.2 SRSS are at or exceed 85K. Based on a review of this study and information in Bouchey, 1982a; GE SMA 12109.01; and NEDE-24010-P, the NRC staff has determined that the SRSS method for combining dynamic responses is applicable to the WNP-2 nuclear plant and satisfies the requirements of "Methodology for Combining Dynamic Responses," NUREG-0484, Revision 1 (July 1981). This resolves confirmatory item 6.

In the SER, the NRC staff also stated that the applicant committed to perform a plant-unique American Society of Mechanical Engineers "Boiler and Pressure Vessel Code (ASME Code),Section III, Class 1 fatigue evaluation for the SRV discharge pipings and downcomers. The NRC staff has reviewed the information on the fatigue analysis on these lines described in the WNP-2 Design Assessment Report dated January 21, 1983. The fatigue evaluation of 24- and 28-inch downcomer lines and all 18 SRV lines in the wetwell air volume was performed using ASME Code,Section III, Class 1 rules. The results of these analyses indicated that the maximum fatigue usage factor for both downcomers and all .18 SRV lines was below ASME Code-allowable limits. The NRC staff finds that the applicant's evaluation satisfies the ASME Code, Section III, Class 1 fatigue evaluation requirement and is acceptable. This resolves confirmatory item 5.

The NRC staff contracted with the Energy Technology Engineering Center to perform an independent analysis of the main steam relief line 10" MS(18)-2 SRV WNP-2 SSER 3 3-3

analysis verified that the piping system me't the applicable ASME Code accept-ance requirements. The, detailed results of this analysis are documented in the Energy Technology Engineering Center report, "WPPSS No. 2 Confirmatory Piping Analysis," dated July 6, 1982 and its attachment dated November 2, 1982.

3. 10 Seismic and D namic uglification of Seismic Cate or I Mechanical and Electrical E ui ment'.
10. 1 Seismic and Dynamic gualification The staff evaluation of the applicant's program for qualification of safety-related electrical and mechanical equipment for seismic and dynamic loads consists of (1) a determination of the acceptability of the procedures used, standards followed, and the completeness of the program in general, and (2) an audit of selected equipment items to develop the basis for the staff judgment on the completeness and adequacy of the implementation of the entire seismic and dynamic qualification program. The Seismic gualification Review Team (SgRT) consists of NRC staff engineers and personnel from the Idaho National Engineering Laboratory (INEL, EG8G). The SgRT has reviewed the equipment dynamic qualification information in FSAR Sections 3.9.2 arid 3. 10 and visited the plant site on November 16 through November 19, 1982 to determine the extent to which the qualification of equipment as installed at WNP-2 meets the current licensing criteria as described in Institute of Electrical and Electronics Engineers (IEEE) Standard 334-1975; RGs 1.92 and l. 100; and SRP 3. 10.

Conformance with these criteria is required to satisfy the applicable portions of GDC 1, 2, 4, 14, and 30, as well as Appendix B to 10 CFR 50 and Appendix A to 10 CFR 100. A representative sample of safety-related electric and mechanical equipment, as well as instrumentation, included in both the nuclear steam supply system (NSSS) and the balance of plant (BOP) scopes of review, was selected for the audit. The plant site visit consisted of field observa-tions of the actual final equipment configuration and its installation. This was immediately followed by the review of the corresponding test and/or analysis documents that the applicant maintains in his central files.

Observing the field installation of the equipment is required to verify and validate equipment modeling employed in the qualification program. Based on the audit, the SgRT concluded the applicant has properly implemented the seis-mic and dynamic qualification program. However, some concerns, both plant generic and equipment-specific remain; these are delineated in Subsec=

tions 3. 10. 1. 2 and 3. 10. 1. 3. These concerns must be satisfactorily resolved before fuel loading. The plant generic concerns are more significant, in that they apply to all safety-related equipment and potentially can affect a large number of components and systems. The applicant must develop an acceptable approach and plan to resolve the plant generic findings.

The audit identified the need to provide additional information on certain plant generic findings as well as to clarify the details of qualification for some pieces of equipment. These findings are summarized below.

WNP-2 SSER 3 3-4

3.10.1.1 Plant Generic Findings A unique feature of the containment design is that the reactor building founda-tion is not integral with the. containment foundation. Hydrodynamic loads inside containment are included in, the qualification of equipment. Outside containment, but inside the reactor building, hydrodynamic loads are not considered, because the unique design of containment is alleged to attenuate these loads. The staff review in this area is continuing and will be completed in additional meetings with the applicant.

Mhen the valve operator BOP-12 was qualified, an assumed g value was used.

Later, in the as-built and as-installed condition, an analysis confirmed that the g value used in the qualification was indeed adequate. This is also the case with other equipment in this category as far as loads are concerned. The applicant indicated that a procedure is in place to verify assumed g values for each case. For the motor operator, the g value was confirmed to be adequate.

The applicant is to confirm the adequacy of all assumed g values and inform the NRC in writing of the results when this confirmation is completed.

The motor control center was qualified through single frequency, biaxial input tests. The motor control center has more than one natural frequency below 33 Hz. This technique, in the absence of adequate justification, is not accept-able. The applicant is to review the cases in which single frequency tests have been used in spite of the presence of multiple natural frequencies of the system within the range of 33 Hz. In each case, the applicant is to provide a justification for single frequency testing.

All safety-related equipment should be qualified and installed before fuel loading. At the time of the audit, some safety-related equipment remained to be qualified and installed. Before fuel loading the applicant must state in writing that all (100%) of the plant safety-related equipment is qualified and installed.

3. 10. 1. 2 Speci fic Issues Pressure Switch BOP-14 The panel on which this item is mounted was qualified by test. The test con-sisted of multifrequency, multi-axis, random inputs. Test Response Spectra (TRS) from these tests enveloped the initial Required Response Spectra (RRS).

Subsequently, based on further investigation, the RRS were changed, with the result that the TRS did not envelope the RRS in different regions. An effort was made to analyze this apparent inadequacy based on the natural frequency of the system. From this analysis, the lowest natural frequency of the system is

'estimated as 7.5 Hz. One unenveloped region is around 6.5 Hz, which is too close to the system frequency. As a result, the adequacy of the qualification test is in doubt. The applicant is to justify his present qualification or requalify the equipment.

3. 10. 1. 3 Summary Based on the SgRT audit findings as well as on submittals from the applicant, with the exception of the concerns mentioned, the staff concludes that an MNP-2 SSER 3 3-5

appropriate seismic and dynamic qualification program has been defined and substantially implemented. This provides adequate assurance that such equip-ment will function properly during and after the excitation from vibratory forces imposed by the safe shutdown earthquake.

Resolution of the specific and generic pl'ant items as they progress will be reported in a future supplement to the SER.

3. 10. 2 Operability qualification of Pumps and Valves To ensure that the applicant has provided an adequate program for qualifying safety-related pumps and valves to operate under normal and accident condi-tions, the NRC staff performs a two-step review. The first step is a review of FSAR Section 3.9.3.2 for the description of the applicant's pump and valve operability assurance program against SRP 3. 10. Because the information in the FSAR is general and not sufficient to evaluate the applicant's overall pump and valve operability qualification program, the Pump and Valve Operabil-ity Review Team (PVORT) also conducts an onsite audit.

The onsite. audit includes a plant inspection to observe the as-built configura-tion and installation of the equipment, a discussion of the system in which are located and of the normal and accident conditions under which the component must operate, and a review of the qualification documentation (stress reports, test reports, etc.).

The two-step review is performed to determine the extent to which the qualifi-cation of equipment, as installed, meets SRP 3. 10, as well as GDC 1, 2, 4, 14, and 30 and Appendix B to 10 CFR 50.

The onsite audit for WNP-2 was performed November 16 to 19, 1982. A repre-sentative sample consisting of seven valves and three pumps was chosen for.

review. The sample included both NSSS and BOP equipment. During the review, a number of concerns were raised. Some of these concerns were satisfactorily resolved by the applicant during the audit either by supplying additional information or by providing additional commitments, as appropriate. The remaining concerns and generic findings are summarized below.

3. 10.2. 1 Generic Findings No generic operability concerns resulted from the evaluation of the WNP-2 qualification program for pump and valve operability.

The results of reviewing the document packages for the unannounced components indicate that the applicant has a good central file system from which he can retrieve documents in a relatively short time, as required by SRP 3. 10. This conclusion was further substantiated after a review of the applicant's quality assurance filing system.

The PVORT was given an orientation lecture on the WNP-2 computer-based main-tenance and surveillance program by the supervisor of maintenance. The pro-gram appears to be very comprehensive and incorporates many excellent features.

Some of these include: (1) performing maintenance on all components before pre-operational testing; (2) integrating all pertinent qualification WNP-2 SSER 3 3-6

information (e.g., aging information for age degradable parts) into the main-tenance program, and (3) analyzing subcomponents upon removal to aid in deter-mining changes in replacement schedules. In keeping with the third idea, the applicant is voluntarily participating in the Nuclear Plant Reliability Data System (NPRDS).

The NRC staff concludes that the WNP-2 supply system equipment qualification group is dealing with the equipment qualification issue in a positive manner, and the results of the group's efforts are evident in the applicant's pump and valve operability assurance program.

3. 10. 2. 2 Specific Concerns Su ression Pool Outlet Valve HPCS-V-15 Hi h Pressure Core S ra Suction Isolation Valve During plant walk-down, reviewers observed that the horizontal clearance between the actuator and an adjacent pipe restraint was possibly too small, so that it might affect the operability of the valve under dynamic loads. A review of the documentation revealed that the valve was originally qualified to the interim piping criteria. When the final piping analysis was completed and compared to the interim load, a review by the applicant found that the loads for this component exceeded those calculated using the interim criteria.

The valve is currently being reanalyzed to the loads specified by the final piping analysis.

Confirmation that the valve has been requalified to the new loads must be provided to the staff before fuel load. In addition, the applicant must provide justification that clearance between the valve actuator and the adjacent pipe restraint will not affect valve operability during dynamic loads.

Rockwell 26-inch Globe Valve MS-V-22C Main Steam Isolation Valve During the valve inspection, NRC staff reviewers found: (1) the accumulator was not installed, (2) the installed solenoid valves were not qualified for the environment, and (3) the valve was scheduled to be completely disassembled for cleaning. These problems .were discussed with the startup engineer, and was determined that the valve, as viewed, was obviously not ready for operation.

it The valve, which had been on site for a number of years (the valve was built in 1973), was to be completely refurbished before testing. This refurbishing would include installation of environmentally qualified solenoid valves.

The documentation review revealed that the qualification of the assembly for operability under accident conditions was based on two analyses by Rockwell, RAL-2006, Revision 1, and RAL-1002, Revision 2. A test report (RAL-1004, Revision 0) was also provided for a similar valve (a 20-inch Rockwell Model 1612Y). RAL-1004 stated that the valve had operated with a 0.820-inch deflection. An analysis of the WNP-2 valve calculated a maximum deflection of only 0.270 inches. In addition, it was learned that a seismic test on a similar actuator for a Rockwell 24-inch valve was being reviewed by General Electric to determine if the results of that test could be used to qualify the WNP-2 actua-tor by similarity. The engineer in charge of power ascension testing commented WNP-2 SSER 3 3-7

on the operability of the valve assembly under design conditions.'e stated that the valve is to be tested (closed against flow) at three different power levels--approximately 30% 50K, and 85K. In addition, all the main steam isolation valves (MSIVs) will be closed simultaneously at 100K steam flow. A complete report on the results of the power ascension tests will be avail'able 3 months after completion of the tests.

Although MS-V-22C is presently not operable, the NRC staff's findings indicate that adequate plans are in place to ensure that the valve assembly will be qualified for operability before the power ascension tests. The power ascen-sion tests will then verify operability under normal plant conditions. How-ever, the applicant must provide the results of the ongoing review of a Rockwell seismic test on a similar 24-inch actuator before fuel load. In addition, confirmation that the solenoid valves for the actuators on all MSIVs have been replaced with qualified units must be provided before fuel load.

The qualification program for the safety-related pumps and valves was not complete for a number of components at the time of the audit. In addition to responding to the concerns addressed above, the applicant should provide a schedule for completion of this program.

3. 10. 2. 3 Summary The staff will complete its review when the applicant has provided the required information as stated above and has documented the completion of his pump and valve operability program. The documentation required to close each of the open items addressed in this report is discussed above. Satisfactory resolu-tion of all the open items discussed must be accomplished before fuel load.

A final evaluation of the pump and valve operability program will be performed following satisfactory resolution of the open items discussed above as well as notification that the pump and valve operability assurance program has been completed for all safety-related pumps and valves. The staff will report on the results of its final evaluation of the applicant's program in a future.

3. 11 Environmental uglification of Electric E ui ment Im ortant to Safet and Safet -Related Mechanical E ui ment
3. 11. 1 Intr oducti on Equipment that is used to perform a necessary safety function must be demon-strated to be capable of maintaining functional operability under all service conditions postulated to occur during its installed life for the time it is required to operate. This requirement, which is embodied in GDC 1 and 4 and in Sections I I I, XI, and XVII of Appendix 8 to 10 CFR 50, i s applicable to equipment located inside as well as outside containment. More detailed require-ments, and guidance relating to the methods and procedures for demonstrating this capability for electrical equipment have been set forth in 10 CFR 50. 49, "Environmental qualification of Electric Equipment Important to Safety for Nuclear Power Plants," and NUREG-0588, "Interim Staff Position on Environmental qualification of Safety-Related Electrical Equipment." NUREG-0588 supplements IEEE Standard 323 and various NRC Regulatory Guides and industry standards.

MNP-2 SSER 3 3-8

3. 11. 2 Background NUREG-0588 was issued in December 1979 to promote a more orderly and systematic implementation of electrical equipment qualification programs by industry and to provide guidance to the NRC staff for use in ongoing licensing reviews.

The positions contained in this se'ction provide guidance on (1) how to establish environmental service conditions, (2) how to select methods that are considered appropriate for qualifying equipment in different areas of the plant, and (3) other areas such as margin, aging,. and documentation.

In February 1980, the NRC requested certain near-term operating licence (OL) applicants to review and evaluate the environmental qualification documentation for each item of safety-related electric equipment and to identify the degree to which their qualification programs comply with the staff positions described in NUREG-0588. IE Bulletin 79-01B, "Environmental gualification of Class 1E-Equipment," issued January 14, 1980, and its supplements dated February 29, September 30, and October 24, 1980, established environmental qualification requirements for operating reactors. This bulletin and its supplements were provided to OL applicants for consideration in their review.

A final rule on environmental qualification of electric equipment important to safety for nuclear power plants became effective on February 22, 1983.. This rule, Section 50.49 of'0,CFR 50, specifies the requirements to be met for demonstrating the environmental qualification of electrical equipment important to safety located in a harsh environment. In accordance with this rule, equip-ment for WNP-2 may be qualified to the criteria specified in Category II of NUREG-0588.

The qualification requirements for mechanical equipment are principally con-tained in Appendices A and B of 10 CFR 50. The qualification methods defined in NUREG-0588 can also be applied to mechanical equipment.

In response to the above requirements, the applicant has provided equipment qualification information in letters dated January 14, 1982, September 15, 1982, and January 31, 1983 to supplement the information in FSAR Section 3~ 11.

The following subsections evaluate the adequacy of the WNP-2 environmental qualification program for electric equipment important to safety as defined in 10 CFR 50.49 and for safety-related mechanical equipment. The staff review, includes an evaluation of the completeness of the list of systems and equipment to be qualified, the criteria which they must meet, the environments in which they must function, and an assessment of the qualification documentation for the equipment. It is limited to electric equipment important to safety within the scope of 10 CFR 50.49, and safety-related mechanical equipment. Equipment required to mitigate scram discharge volume (SDV) breaks as described in NUREG-0803, "Generic Safety Evaluation Report Regarding Integrity of BWR Scram System Piping," will be evaluated separately.

3.11.3 Staff Evaluation The staff evaluation of the applicant's environmental qualification program included an onsite examination of electrical equipment, audits of qualification documentation, and a review of the applicant's submittals for completeness and WNP"2 SSER 3 3-9

acceptability of systems and components, qualification methods, and accident environments. The criteria described in SRP 3. 11 (NUREG-0800) and NUREG-0588, Category II, form the basis for the staff evaluation of the adequacy of the applicant's qualification program. Revision 1 of NUREG-0588 was utilized to clarify staff positions as required.

The staff performed an audit of the applicant's qualification documentation and installed electrical equipment on February 15 through 17, 1983. The audit consisted of a review of 10 files containing equipment qualification docu-mentation. The staff's findings during the audit are discussed in detail in Section 3. 11.4.2 below. Mechanical equipment environmental qualification was also reviewed.

3. 11.3. 1 Completeness of Equipment Important to Safety The applicant was directed to (1) establish a list of systems and components that are required to prevent or mitigate a loss-of-coolant accident (LOCA) or a high-energy line break (HELB) and (2) identify components needed to perform the functions of safety-related display instrumentation, post-accident sampling and monitoring, and radiation monitoring.

The applicant's systems list for the environmental qualification program was compared to FSAR Table 3.2;l. Omissions from the harsh environment program were adequately justified by the applicant. Appendix 30, appended to this section, lists the systems identified and their safety function.

Based on information in the applicant's submittal, the staff has verified and determined that the systems included in the applicant's submittal are those required to achieve or support: (1) emergency reactor shutdown, (2) contain-ment 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 applicant has identified the equipment required by NUREG-0737, "Clarification of TMI Action Plan Requirements," but the qualification status has not been established for all items. Before an operating license is granted, the appli-cant should identify the qualification status for all TMI Action Plan equipment.

For any TMI Action Plan equipment not yet installed and that will not be installed prior to operation, a description of the plans for qualification, including the schedule for completion of qualification, must be submitted.

(All TMI Action Plan equipment currently installed or that will be installed before operati'on must be qualified, or justifications for interim operation provided before an operating license is issued, in accordance with 10 CFR

50. 49. )

To comply with 10 CFR 50.49, the following information must be submitted by the applicant before an operating license for MNP-2 can be granted:

(1) A list of all nonsafety-related electrical equipment, located in a harsh environment, whose failure under postulated environmental conditions could prevent satisfactory accomplishment of safety functions by the safety-related equipment. A description of the methods used to identify

'4NP-2 SSER 3 3-10

this equipment must be included. The nonsafety-related equipment iden-tified must be included in the environmental qualification program.

(2) A statement that all safety-related electrical equipment in a harsh environment,'s defined in the scope of 10 CFR 50.49, is included in the list of equipment identified in the September 1982 submittal.

(3) A list of all post-accident monitoring equipment currently installed, or that will be installed before plant operation begins, that is specified =as Category 1 and 2 in Revision 2 -of RG 1.97 and is located in a harsh environment. The equipment identified must be included in the environmental qualification program.

3. 11.3.2 qualification Methods
3. 11.3.2. 1 Electrical Equipment in a Harsh Environment Detailed procedures for qualifying safety-related electrical equipment in a harsh environment are defined in NUREG-0588. The criteria in NUREG-0588 are also applicable to other equipment important to safety as defined in 10 CFR 50.49. Type testing of equipment in a sequence consisting of pre-aging (thermal, radiation, and mechanical), seismic and dynamic loading, and exposure to LOCA/

HELB conditions (where applicable) is the prefer red method of qualification.

However, in a number of cases the applicant has extrapolated partial test data to establish the equipment qualfication. The staff has reviewed this analysis and finds the approach to be adequate except as noted in this report.

3. 11.3.2.2 Safety-Related Mechanical Equipment in a Harsh Environment Although ther e are no detailed requirements for mechanical equipment, GDC 1 and 4; Sections III and XVII of Appendix 8 to 10 CFR 50; and SRP 3. 11, Revision 2, contain the following requirements and guidance related to equip-ment qualification:

~

Components shall be designed to be compatible with the postulated environ-mental conditions, including those associated with LOCAs.

Measures shall be established for the selection and review for suitability of application of materials, parts, and equipment that are essential to safety-related functions.

~

Design control measures shall be established for verifying the adequacy of design.

~

Equipment qualification records shall be maintained and shall include the results of tests and materials analyses.

The staff review is concentrated on materials that are sensitive to environ-mental effects (for example, .seals, gaskets, lubricants, fluids for hydraulic systems, and diaphragms). qualification documentation was reviewed by the staff to verify conformance with the above criteria. The results of the staff review are in Section 3. 11. 4. 3 below.

WNP-2 SSER 3 3-11

3. 11.3.3 Service Conditions NUREG-0588 defines the methods to be utilized for determining the environmental conditions associated with LOCAs or HELBs, inside or outside of containment.

The review and evaluation of the adequacy of these environmental conditions are described'elow. The staff has reviewed the qualification documentation to ensure that the qualification conditions envelop the, conditions established by the applicant.

3. 11.3.3. 1 Temperature, Pressure; and Humidity Conditions Inside the Primary Containment The applicant provided the LOCA/main steamline break (MSLB) profiles used for equipment qualification program submittals. The peak values in the drywell resulting from these profiles are as follows:

Maximum Maximum pressure, tern erature F LOCA/MSLB 340 45 100 The staff has reviewed these profiles and finds them acceptable for use in equipment qualification; i.e., there is reasonable assurance that the actual pressures and temperatures will not exceed those profiles anywhere within the specified environmental zone (except in the break zone).

3. 11.3.3.2 Temperature, Pressure, and Humidity Conditions Outside the Primary Containment The applicant has provided the temperature, pressure, and humidity conditions associated with HELBs in the secondary containment. The staff has used a screen-ing criterion of saturation temperature at the calculated pressure to verify that the parameters identified by the applicant are acceptable. The applicant should indicate that the postulated environmental conditions associated with moderate-energy line breaks are no more severe than the conditions associated with high-energy line breaks.
3. 11.3. 3. 3 Submer gence The maximum submergence level established by the applicant in the environmental qualification program is 12 inches above the drywell floor. The applicant has stated that there are no exposed connections or equipment located between the diaphragm floor and the top of the downcomer vent pipes inside the wetwell, except for the wetwell level system, which-is totally enclosed in watertight conduit.

The effects of flooding on equipment located in the reactor building have been evaluated to ensure that safe shutdown can be achieved. All impacted equipment will either be protected, relocated, or qualified.

The applicant should indicate that any equipment important to safety that could be subjected to flooding will not affect the safety function of any other equip-ment or system and will not mislead the operator.

MNP-2 SSER 3 3-12

3.11.3.3.4 Demineralized Water Spray A demineralized water spray could be used inside primary containment to mitigate the effects of an accident. Spray impingement on affected equipment has been evaluated by the applicant and has been included in the qualification program.

3. 11. 3.3. 5 Aging NUREG-0588, Category II delineates two aging-program requirements. Valve operators committed to IEEE Standard 382-1972 and motors committed to IEEE Standard 334-1971 must meet the Category I requirments of NUREG-0588. This requires the establishment of a qualified life, with maintenance and replace-ment schedules based on the findings. All other equipment must be subjected to an aging program that identifies aging-,susceptible materials within the component.

In addition to the above, a maintenance/surveillance program should be implemented to identify and prevent significant age-related degradation in electrical and mechanical equipment. The applicant has committed to follow the recommendations in RG 1.33, Revision 2, "equality Assurance Program Requirements (Operation),"

which endorses American National Standard ANS-3.2/ANSI N18.7-1976, "Administra-tive Controls and equality Assurance for the Operational Phase of Nuclear Power Plants," as noted in SER Section 17. This standard defines the scope and content of a maintenance/surveillance program for safety-related equipment. Provisions for preventing or detecting age-related degradation in safety-grade equipment are specified and include (1) utilizing experience with similar equipment, (2) revising and updating the program as experience is gained with the equip-ment during the life of the plant, (3) reviewing and evaluating malfunctioning equipment and obtaining adequate replacement components, and (4) establishing surveillance tests and inspections based on reliability analyses, frequency and type of service, or age of the items, as appropriate. The applicant must commit to implementation before an operating license is granted.

3. 11.3.3.6 Radiation (Inside and Outside Containment)

The applicant has provided values of the radiation levels postulated to exist following a LOCA. The accident radiation environments in primary containment .

have been defined according to Section II.B.2 of NUREG-0737 and NUREG-0588, Revision 1. For this review, the staff has assumed that the values provided have been determined in accordance with the prescribed criteria. The staff review determined that the values to which the equipment was qualified enveloped the requirements identified by the applicant, except as noted in Section 3.11.4.2 below.

The radiation service condition specified by the applicant for primary contain-ment are: 7. 0 x 10~ rads in the drywell; 9 x 10~ rads in the wetwell; and 3.7 xlO rads in the suppression pool. In the secondary containment,: required values of up to 1.2 x 10 rads gamma were used in the evaluation of equipment in areas exposed to recirculating fluid lines. These values are acceptable for use in the qualification of equipment.

In addition the applicant was directed to evaluate any possible radiation-induced damage to solid state devices and the effect of beta radiation on WNP-2 SSER 3 3-13

equipment important to safety. The applicant has indicated that an investiga-tion is under way and corrective action will be taken as required.

3. 11.3.4 Outstanding Equipment For items not having complete qualification documentation, the applicant must provide a commitment for corrective action and schedules for completion. For items that will not have full qualification before an operating license is .

granted, analyses must be performed in accordance with paragraph (i) of 10 CFR 50.49 to ensure that the plant can be operated safely pending completion of environmental qualification. These analyses must be submitted for consideration before the granting of an operating license.

In his list of equipment, the applicant has identified a manual control switch, General Electric type CR 2940. This switch has recently been identified as having failed after exposure to radiation aging. The applicant should review the specific use of this switch in the plant and ascertain that this equipment is suited for its application.

The applicant also has stated that the required minimum operating time margin of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> was not applied in certain specific cases. The specific equipment should be identified by the applicant for staff review.

3. 11.4 qualification of Equipment The following subsections present the staff assessment based on the applicant's submittal, audits of documentation at the plant site, information in the NRC Equipment qualification Data Bank, and previous staff evaluations of equipment in other plants.
3. 11.4. 1 Electric Equipment in a Harsh Environment The applicant has committed to completing several analyses important to the validity of the equipment qualification program, as stated in Section 3. 11. 3. 3. 6 above. The applicant has also committed to provide an updated Environmental Equipment gualfication Report to reflect any changes in the qualification status and information provided to the staff. Because of these expected revisions, Appendices 3A, 3B, and 3C, which would normally list the equipment items and their qualification status, will not be included in this SER. These appendices will be provided in a future supplement after the revised submittal is reviewed.
3. 11. 4. 2 Environmental qualification Audit The staff, with assistance from EG8G Idaho, Inc., performed an audit of the applicant's qualification files on February 15 through 17, 1983. The audit consisted of a review of 10 files containing information regarding the quali-fication status of the equipment. There were a number of exceptions taken with the findings of the applicant regarding the qualification status of the equipment. Based on the results of the audit, the staff has determined the following:

MNP-2 SSER 3

For 3 of the 10 items reviewed that were classified by the applicant as qualified, the required accuracy had not been developed and compared with the demonstrated accuracy during testing. These itmes should be reclassified as not fully qualified until the demonstrated accuracy under accident conditions is shown to envelop the required accuracy. The staff may select several pieces of equipment for detailed review of the resolution of this item before licensing.

(2) Modifications to installed transmitters resulting from IE Bulletin 80-16 had not been considered in the evaluation of the qualification information.

Although the applicant satisfactorily addresses the effects of these modi-fications, he should address how changes to other equipment items resulting from IE Bulletins, Circulars, and Information Notices have been or will be evaluated for their impact on qualification.

(3) For the same transmitter, the applicant determined by the Arrhenius equa-tion that an "0-ring" sealing the electronics housing had an expected life of 40 years. However, the applicant was unable to address the type and frequency of surveillance to be performed to determine if unanticipated age-related degradation is occurring. Recent information has revealed that a failure was observed during qualification tests of Rosemount trans-mitters as a result of the inability of the seal to prevent steam ingress into the electronics housing. Based on this, the staff will not accept analysis in lieu of testing to address the effects of age-related degrada-tion on the seals of any equipment containing susceptible electronic components, unless there are valid reasons to the contrary (environmental conditions, etc.).

One other file, for a level switch, did not contain aging data to support a calculated life of 40 years and only selected pages of a referenced test report were included in the file. The complete test report was provided at the end of the audit but was not made part of the qualification file.

A cursory review of the report revealed that maintenance was required at 1- and 5-year intervals to obtain a 40-year life. The applicant did not address these requirements.

Because aging was addressed exclusively by analysis in the majority of the files reviewed, the applicant should describe the approach that will be taken to account for material degradation.

(4) During the plant walk-down it was noted that flexible conduit connected to electrical equipment had not been included in the environmental qualifi-cation program. Failure of this conduit under accident conditions could permit steam to enter sealed portions of instruments and cause equipment failures. This item should be added to the program and qualified for the postulated environments.

Also noted during the walk-down were several instances where the installed equipment was not representative of the tested equipment, specifically An electronics housing for a transmitter did not contain a threaded metal plug for sealing but instead used a plastic insert intended only to protect the threads. The insert does not provide leaktight WNP-2 SSER 3 3-15

integrity and could permit steam from a high-energy line. break to enter the housing.

~

A pressure switch was described as being sealed with RTV silicone

.rubber at the lead wire entrance cavity to exclude moisture from the device internals during .qualification tests. This type of sealing was not evident at plant installation, and the applicant could not determine if the same type of sealing was provided in the installed configuration.

Because of the discrepancies identified, the applicant should reeva'luate the adequacy of the plant walk-down performed before the staff's audit.

From the information in the qualification files on installed equipment and the results of the staff's walk-down, it is apparent that environmental qualification concerns were not adequately addressed. The staff will review the applicant's approach to the resolution of this item prior to licensing.

{5) One item that could be exposed to elevated temperatures and 100%%uo'elative humidity from a high-energy line break was qualified by evaluation of tests for individual components in the device; type testing of the assembled device had not been utilized as required by NUREG-0588. Although addi-tional review by the applicant established that the item, a transformer, was not required to function during line break conditions, other equipment in the program may have been similarly reviewed and considered to be qualified. The applicant indicated during the audit that all other equipment has been qualified for steam conditions by type testing. To verify this, the staff will review the applicant's revised list of equip-ment and compare qualification methods with those described in the staff's Equipment qualification Data Bank.

(6) During the plant walk-down and review of the qualification files, it was evident for one item that traceabi lity and similari.ty between the tested piece of equipment and the installed equipment was not established. The applicant has not demonstrated conclusively that the material data reported in the files apply to the component materials of the installed equipment.

The applicant should review the qualification program and establish that all data reported are applicable.

3. 11.4.3 Environmental qualification of Mechanical Equipment Three mechanical equipment qualification files were reviewed by the staff.

In general the same comments made for electrical equipment apply to the mechanical equipment. qualification is based on analysis to a great extent, especially to demonstrate radiation and aging resistance. For example, radia-tion resistance of the "0-rings" on a "qualified" air operator on the main steamline is achieved by a vague referenced statement that in one test the "seals perform acceptably." Similarity of material compound and similarity of application were not demonstrated. For another material, the required radia-tion dose was not enveloped by the reported qualification dose. A replacement interval was not specified to justify the lower value.

WNP-2 SSER 3 3" 16

The applicant should review the mechanical equipment qualification files to ascertain tHat all deficiencies are removed. The staff may select additional pieces of equipment for detailed review. Additionally, the applicant shou'Id submit the results of his review for all safety-related mechanical equipment located in a harsh environment. For any equipment that will not be demon-strated fully qualified before an operating license is granted, justification for interim operation should be submitted, along with proposed corrective actions and a schedule for completion.

3. 11. 5 Conclusions On the basis of its review, the staff finds that the applicant must provide the required information, identified above, to demonstrate full compliance with 10 CFR 50.49 and all applicable regulations. The qualification information should be provided to allow sufficient tipe for staff review and approval before an operating license is issued. The staff's evaluation wi')') be addressed in a future supplement.

4 REACTOR 4.2 Fuel S stem Desi n 4.2.3 Design Evaluation 4.2.3. 1 Fuel System Damage Evaluation (4) External Corrosion and Crud Buildu Waterside Corrosion Corrosion problems associated with stainless steel cladding in boiling water reactors (BWRs), together with a desire to improve neutron economy, led to a change some years ago from stainless steel to Zircaloy cladding material, which has good resistance to the hot water and steam environment encountered under typical BWR operating conditions (Garzarolli et al., 1978). In several recent cases, however, cladding failures have been associated with external "waterside" corrosion (GE Projects Division Memorandum, 1979, and Manry, 1981),

and these occurrences have been characterized by GE as "crudinduced local corrosion failure" (NEDE-24343-P). The corrosion is reportedly associated with a variably high copper concentration in the core coolant water and a minor anomaly in the Zircaloy cladding metallurgy (Charnley, 1979; Engel, 1980; Smith, 1980; Smith, 1981; and DelGeorge, 1980). The source of the copper contamination in the affected plants appears to be the copper-bearing main condenser tubes (DelGeorge, 1980). All the plants affected have copper alloy condenser tubing. It is notable also that virtually all the BWR waterside corrosion failures have involved gadolinia burnable poison rods.

The NRC staff has been following this issue generically, and in a recent meeting with the staff, GE identified (Tokar, 1982) what were believed to be some factors responsible for the corrosion, failures and stated that a change had been made in the manufacturing process to ensure that such fai lures will not occur in newly manufactured fuel bundles. GE's presentation provided an explanation of the problem, and the solution appears plausible (ibid).

Further documentation on this subject has been provided in a recent letter from the applicant (Bouchey, 1982c). This letter confirmed that all susceptible cladding will be eliminated from the WNP-2 environment. The staff, therefore, concludes that this issue should be considered resolved for WNP-2.

Crud Bui ldu The buildup of a corrosion film and a crud layer on the outer surface of a fuel rod during irradiation causes gradual flow reductions and impedes heat transfer to the coolant. The effects of crud buildup on flow are discussed in SER Sec-tion 4. 4. 5. As indicated in Section 2. 4. 2. 2 of NEDE-24011, GE calculates the cladding surface temperature using the cladding surface heat flux at a given

axial position of a fuel element in conjunction with an overall cladding-to-

, coolant film coefficient that is taken to represent the combined effects of crud and oxide resistances and a liquid film resistance based on the Jens-Lottes wall superheat equation (Jens and Lottes, 1951). The impact of high cladding temperatures, such as decreased yield strength and reduced cladding thickness due to oxidation, was considered in GE's design evaluation (NEDE-24011). GE's methods for analyzing the effects of oxidation and crud on fuel cladding temperatures were reviewed and approved in connection with NEDE-24011, and the NRC staff, therefore, finds that approach acceptable for WNP-2.

(5)'imensional Chan es Channel Box Deflection Boiling water reactor (BWR) fuel channels provide structural stiffness for the fuel assemblies and distribute the coolant flow between the assemblies and channel bypass regions. The channels are subject to time-dependent, permanent dimensional changes (i.e., deflections) that result from irradiation, creep, and stress-relaxation effects. The resultant bulge (resulting from long-term creep) or bow (resulting from differential irradiation-induced axial growth) reduces the size of the gap available for control blade insertion. Channel box deflection is thus a phenomenon that can limit channel life because of the potential adverse effects on the ability of the control blades to move freely.

In a generic topical report (NEDE-21354-P), General Electric (GE) describes a channel lifetime prediction method and a backup recommendation for periodic channel deflection measurements that consist of settling friction tests. Upon consideration of the factors involved, the NRC staff concluded that the settl-ing friction tests or an acceptable alternative (such as channel dimensional deflection measurements) should be performed, and in a memorandum (Rubenstein, 1981) the staff outlined a method that could be used to resolve the channel box deflection issue f'r several near-term'WR operating license applications, including WNP-2. Basically, the staff advocated a multistep procedure that had been proposed bv the Zimmer applicant. The key ingredient of the Zimmer plan was a commitment to (1) perform some control rod settling friction tests, which would provide an exact profile of control rod drive friction versus position at refueling outages, or (2) make some actual channel dimensional measurements.

Several plants agreed to the Zimmer proposal. Subsequently, the BWR Licensing Review Group (LRG-II) submitted a position paper (Holtzscher, 1982) on channel box deflection that incorporated several of. the same features as the Zimmer proposal (the settling friction test was simplified). The LRG-II position was approved (Rubenstein, 1982) for the LRG-II plants (i.e., River Bend and Perry),

and a letter (Schwencer, 1982) was sent to WPPSS indicating the NRC staff's position on this issue at that time.

In response to the Schwencer letter, WPPSS stated (Bouchey, 1982b) that a channel management program for WNP-2 has been initiated that includes the following features:

(1) Compiling complete operating history records for each channel. Data to be collected include channel location, orientation of welded sides, exposure, and control history.

4-2

(2) Compiling complete analytical history records for each channel including fast fluence (>/MeV) and flux gradient history.

(3) Heasurement of post-operation channel box deflection.

Items 1 and 2 are consistent with the Zimmer and LRG-II proposals. The main difference in the WPPSS program lies in the emphasis on channel box deflection measurements. WPPSS proposes to measure channel box deflection after each refueling outage for selected channels that are discharged to the spent fuel pool. The reuse of discharged channels (the nominal design lifetime of BWR fuel channels is one fuel assembly lifetime, which currently is about 4 or 5 years) would be determined based upon those measurements as compared to predetermined criteria. Other items to be addressed in this program include development of channel manufacturing history data and analytical prediction capability.

In support of its proposed channel management program, WPPSS referred to some recently available data from Commenwealth Edison measurements that indicate that major channel bowing may be a strong function of channel manufacturing history rather than location of the channel within the core. The Commonwealth Edison data alluded to in the WPPSS letter are probably the same as that des-cribed in detail in a recent Electric Power Research Institute (EPRI) report (EPRI NP-2483) on a rather exhaustive study funded by EPRI. As indicated in the Bouchey letter (1982b) (and in Section 4 of the EPRI report), the Common-wealth Edison data indicate that prime candidates for channel bowing are those manufactured from mismatched halves; i.e., channels manufactured from two pieces of stock material not from the same original batch. It is notable that Car Tech channels avoid this potential problem because the channels are made by rolling and welding single sheets of material. The GE fabrication process, on the other hand, does not preclude use of unmatched halves. WPPSS has ident-ified which of the WNP-2 channels are manufactured from mismatched halves (75 out of 764) and has set up special plans to manage the use of these channels to minimize potential bowing. Those measures will include taking advantage of core locations that are not adjacent to control blades and identifying locations of minimal exposure and fast flux tilt. In addition, WPPSS is proposing to take a number of operational actions to monitor channel distortion in the core, including scram time and rod notch testing prior to startup after each reload.

For control rods that fai 1 those tests, the settling friction test described in Section 4.4.2 of NEDE-21354-P would be performed.

The above described channel box management program committed to by the applicant for WNP-2 reflects the latest state-of-the-art information on this issue and is supported by results of a comprehensive study funded by EPRI. Based on the information from that study, the NRC staff concludes that the proposed program is eminently sound and that its implementation by WPPSS wi 11 provide adequate assurance that channel box deflection will not become a problem in WNP-2. This removes the need for potential license condition 2.

Fuel Rod Bowin A 1977 version of a GE fuel experience report (NEOE-21660-P) stated that BWR fuel operating experience, testing, and analysis indicate that there is no significant problem with rod bowing. The staff recently completed (Rubenstein, 4-3

1983) a review of a GE generic topical report (NEDE-24289-P) that is intended to update the GE rod bowing experience. On the bases of (1) the reported GE data base and GE's statement that "To date, no significant fuel rod bowing has been detected in GE BWR fuel assemblies" Lsic, excluding segmented-rod designs]

and (2) the NRC staff's calculations using other vendors'roprietary informa-tion, the NRC staff concludes that significant fuel rod bowing in GE BWR fuel is not anticipated and no operational penalties on GE BWR fuel are warranted at this time. If adverse rod bowing behavior (gap closures greater than 50K) is observed in GE-supplied fuel in the future, NRC should be notified to ascertain the need for critical power ratio penalties. This resolves confirmatory item 12.

4.6 Functional Desi n of Control Rod Drive S stem In the SER, the NRC staff stated that its review of the applicant's response to the'ffice of Analyses and Evaluation of Operational Data (AEOD) May 3, 1981 report entitled "Safety Concerns Associated with a Pipe Break in the BWR Scram System" was not complete. The NRC staff has completed its review of the appli-cant's submittal and the additional information provided by submittals dated December 9, 1982 and February 3, 1983. The results of the applicant's analysis indicated that the scram system pipe break identified in the AEOD report would not result in flooding of safety-related equipment and would not produce any adverse environmental effects. The applicant provided a discussion of the pro-cedure needed to isolate such a reactor coolant system leak and verified that the effects of the escaping reactor coolant would not prevent personnel from enter-ing the area and isolating the leak. Thus the applicant has adequately addressed the May 3, 1981 AEOD report concerns, and the NRC staff agrees with the applicant's conclusions.

Based on the above, the NRC staff concludes that the applicant has adequately addressed the concerns expressed by AEOD in its May 5, 1981 report. The design of the control rod drive system meets the applicable acceptance criteria of SRP 4. 6 {NUREG-0800). This resolves outstanding issue 28.

7 INSTRUMENTATION AND CONTROL 7.3 En ineered Safet Features S stems

7. 3. 2 Specific Findings 7.3.2.4 Standby Service Water System The standby service water (SSW) system was designed to use multiplexed signals to operate associated pumps and valves. The NRC staff raised several concerns regarding the use of multiplexing in this Class lE application. Of particular concern were the potential effects of electromagnetic interference (EMI) on the SSW multiplexer systems, and the inability to manually operate SSW system components remotely, independent of the multiplexer systems.

The applicant has since committed to implement design modifications that will remove all safety-related functions from the multiplexers. This will allow (1) the functioning of the SSW pumps and valves in 'the primary flow path with-out the multiplexer, and (2) manual initiation/control capability for SSW components from the control room, independent of the multiplexers. The multiplexers will remain operational, providing the operator with supple-mentary information fr'om the SSW pumphouse. Examples of this information are spray pond level and temperature, pump discharge pressures, and pump motor and bearing temperatures. Sufficient instrumentation independent of the multiplexers is provided in the control room to allow the operators to verify SSW system operability. This instrumentation includes valve position and pump running status lights, SSW flow through the RHR heat exchangers, and low flow alarms for the components served by the SSW system. The applicant plans to complete these modifications before fuel load.

The NRC staff has determined (based on its review of the SSW system as described and on supporting information provided in WPPSS letters G02-83-167 dated February 23, 1983, and G02-83-266 dated March 28, 1983) that the SSW system instrumentation and controls are acceptable. This resolves outstanding item 10.

The applicant will be required to submit the final drawings (electrical schematics) for the affected components for confirmatory review when the design modifications are completed. This resolves outstanding issue 10.

7.6 All Other Instrumentation S stems Re uired for Safet 7.6.2 Specific Findings

7. 6. 2. 3 Rod Bl ock Moni tor The NRC staff identified four concerns regarding the WNP-2 rod block monitor (RBM) function as stated in the SER. These are WNP-2 SSER 3 7-1

(1) The four flow monitors are interconnected by armored cable and shielded cables, and there are open spaces around the cables that penetrate fire barriers between redundant channels.

(2) Both RBM channels are connected by data buses that are enclosed in a metal shield and run along the top of the cabinet.

(3) The wiring of the RBM bypass switch may not satisfy the separation criterion (minimum separation of 6 inches).

(4) The RBM is a modified design and contains multiplexing circuitry that interfaces with the new reactor manual control system.

The WNP-2 RBM is identical to other RBM designs for which the above four concerns were identified and subsequently resolved. The applicant was to confirm that similar plant modifications to resolve these concerns have been implemented. The applicant has submitted information indicating that correc-tive actions to resolve these concerns have been or will be implemented as fol 1 ows:

(j.) As stated in the NRC staff's fire protection review (SER Section 9.5. 1),

the applicant has committed to inspect all fire barriers within the plant and to seal any unsealed penetrations with an approved fire resistant material with a rating equivalent to that of the barrier itself. Any deficiencies regarding the open spaces identified above will be corrected, according to the applicant's commitment. This resolution is acceptable to the NRC staff.

(2) The NRC staff reviewed the tests performed on the devices used to isolate the redundant RBM channels from each other in the Zimmer design and con-cluded that these devices provide adequate isolation. The applicant has indicated that these same devices are used in the WNP-2 RBM design.

Therefore, the NRC staff considers this item resolved.

(3) The applicant has stated that the wiring of the WNP-2 RBM bypass switch is being rerouted to provide acceptable separation. The NRC staff considers this item resolved.

(4) The multiplexing circuitry employed in the WNP-2 RBM and reactor manual control system processes and transmits information about reactor status, control rod position, rod block logic, and rod control logic through common electrical circuits. In earlier BWR designs this was accomplished by individual circuits. The new design has a self-testing capability to ensure that this information is being processed correctly. The NRC staff believes that the new multiplexing design is acceptable, provided this self-testing capability is, formally implemented through Technical Specifications. The Technical Specifications will require that this is done.

On the bases discussed above, the NRC staff has concluded that the WNP'-2 RBM is acceptable. This resolves confirmatory item,20.

WNP-2 SSER 3 7-2

9 AUXILIARY SYSTEMS 9.5 Other Auxiliar S stems 9.5.1 Fire Protection Program In the SER, two open items concerning fire protection were identified: verifi-cation of unlabeled fire doors, and deletion of a fire suppression system in fire areas.

By letters dated April 22, June 30, September 20, October 4, and October 5, 1982, the NRC staff received additional information concerning these open items.

In the SER, the NRC staff also stated that the applicant proposed to equip all manual hose stations in the plant with 150 feet of hose. At the request of the NRC staff, by letter dated January 28, 1983, the applicant agreed to modify the standpipe hose system to provide enough hose stations so that effective water streams can reach any area of the plant with a maximum of 100 feet of 1 1/2-inch hose, in accordance with Section C. 6. c of BTP CMEB 9. 5-1. By letter of March 4, 1983, the applicant proposed to deviate from the NRC staff guidelines by equip-ping hose stations in the reactor building with 150 feet of hose. This devia-tion was justified on the basis of water distribution system hydraulics, the capabilities of the plant fire brigade, and the cost and potential repercussions of a fire on safety-related equipment, SER Sections 9. 5. 1. 5(l), 9. 5. l. 6(3), 9. 5. l. 8, and 9. 5. l. 9 have been revised to reflect the results of the NRC staff evaluation of this information.

9.5. 1.5 General Plant Guidelines

( )

Fire areas are defined by walls and floor/ceiling assemblies. Walls that separate buildings and walls between rooms containing safe shutdown systems are 3-hour-fi re rated. Floor/ceiling assemblies are 1-1/2-, 2-, or 3-hour-fire-rated assemblies. In cases where the fire rating is less than 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, the staff has evaluated the fuel loading and fire protection provided and found the fire rating acceptable. By letter dated December 9, 1981, the applicant has committed that all fire-rated walls and floors/ceilings will be qualified in accordance with ASTM E-119. Based on its review, the NRC staff concludes that the fire-rated walls and floor/ceiling assemblies are provided in accordance with the guidelines of Branch Technical Position (BTP) CMEB 9. 5-1, Section C.5. a," and are, therefore, acceptable.

By letter dated December 9, 1981, the applicant has also committed to provide 3-hour-fire-rated penetration seals. The penetration seals are verified by a 3-hour-fire test in accordance with the ASTM E-119 fire test procedure. Based on this, the NRC staff concludes that the fire seal ratings meet the guidelines of BTP CMEB 9.5-1, Section C.5.a, and, therefore, are acceptable.

WNP-2 SSER 3 9-1

Door openings in rated fire barriers are provided with labeled fire doors, except for several doors that are nonrated airtight doors. By letter dated April 22, 1982, the applicant provided additional information to verify that the airtight doors are similar in construction to labeled fire doors. The doors and frames are constructed of heavy gauge welded steel, with 2-1/4 inches of internal insulating material. The doors, when closed, will be able to withstand the anticipated fire exposure, represented by burning in situ and transient combustibles, and prevent the passage of smoke as well as convective and radiant heat as effectively as a labeled fire door. This resolves confirmatory item 23.

The applicant, in Amendment 19, has committed that the fire doors will satisfy the requirements of Appendix R to 10 CFR 50, Section N, which pertains to self-closing or administrative-cl'osing procedures. With the commitment the NRC staff finds that the fire doors meet the guidelines of BTP CMEB 9.5-1, and are, therefore, acceptable.

The applicant has provided 3-hour- and l-l/2-hour-fire door dampers in ducts penetrating fire-rated walls. Where duct penetrations have less than a 3-hour-fire rating, the NRC staff has evaluated the fuel loading and fire protection provided and found the fire rating acceptable. Based on its review, the NRC staff concludes that the fire doors and dampers will be provided in accordance with the guidelines of BTP CMEB 9.5-1, Section C.5. 1, and are, therefore, acceptable.

The use of plastic materials, in particular halogenated plastics, has been minimized. No flammable liquids (with the exception of the diesel generator oil day tanks covered in Section 9.5.4.2 of the SER) as defined by National Fire Protection Association (NFPA) Standard 30 are stored 'in the plant. The NRC staff finds that this conforms to the guidelines of BTP CMEB 9.5-1, Section C.5, and is, therefore, acceptable.

Interior walls and structural components, thermal insulation materials and components, and radiation shielding materials are noncombustible. Decontamin-able coatings and finish painting materials have a flame spread of less than

25. The NRC staff finds this to be within the guidelines of BTP CMEB 9.5-1, Section C.5.a, and, therefore, acceptable.

All high-voltage transformers located inside safety-related building areas are insulated or cooled with noncombustible liquid. There are no oil-filled transformers located within 50 feet of the exterior wall of a building containing safety-related equipment. This meets the guidelines of BTP CMEB 9.5-1, Section C.5.a, and is, therefore, acceptable.

9.5. 1.6 Fire Detection and Suppression (3) S rinkler and Stand i e S stems The wet pipe sprinkler system and standpipe hose system are connected to common risers from the underground water supply loop. Looped interior headers are provided. This design is in compliance with BTP CMEB 9.5-1, Section C.5.c, and is, therefore, acceptable.

WNP-2 SSER 3 9-2

The automatic sprinkler systems (wet pipe sprinkler systems, pre-action sprinkler system, and deluge water spray systems) are designed to the pro-visions of,NFPA Standards 13, "Standard for the Installation of Sprinkler Systems," and 15, "Standard for Mater Spray Fixed Systems."

The areas that are being equipped. with automatic water suppression systems are listed in FSAR Amendment 24.

By letter dated January 21, 1982, the applicant stated that 15 fire areas contain cables associated with redundant shutdown systems. To ensure post-fire shutdown capability, these cables must be protected. In FSAR Amendment 24, and in a letter dated October 4, 1982, the applicant revised this number from 15 to 10. The reduced number reflects the establishment of redundant shutdown capabilities in fire areas separate from those plant loca-tions originally identified as containing redundant safety divisions.

The following three areas will be completely protected by an automatic sprinkler system:

(1) cable spreading room (RC-ll)

(2) cable chase (RC-111)

(3) corridor (TG-1)

In the following seven areas, the applicant proposes to deviate from the staff guidelines to the extent that they require automatic fire suppression systems:

(1) remote shutdown room (RC-IX)

(2) switchgear room 82 (RC-XIV)

(3) general floor area (R-1) - elevation 471'-0" (4) general floor area (R-1) - elevation 501'-0" (5) general floor area (R-1) - elevation 522'-0".

(6) general floor area (R-1) - elevation 548'-0" (7) general floor area (R-1) - elevation 572'-0" ln lieu of an automatic sprinkler system, the applicant proposes to completely protect one safety division with a subliming and insulating coating that is capable of withstanding a 3-hour-fire exposure as defined in American Society for Testing and Materials (ASTM) Standard 119. The material has been demon-strated to protect the cable from visible fire damage and to maintain circuit integrity during fire exposure. The material is not adversely affected by a water hose stream and is capable of limiting temperature rise on the unexposed side to not more than 250'F above ambient, which is well below the temperature at which similar Institute of Electrical and Electronics Engineers (IEEE)-

qualified cabling began to fail in tests conducted independently for NRC at Underwriters'aboratories. The NRC staff concludes that this protection, coupled with the smoke detection systems in these areas, provides an equivalent level of fire safety to that achieved by the installation of a sprinkler system.

The NRC staff finds the deletion of automatic sprinkler systems in the proposed areas an acceptable deviation from Section C.6.c. of BTP CMEB 9.5-1. Therefore, the fire protection provided for these rooms is acceptable.

MNP-2 SSER 3 9-3

Manual hose stations are provided in stairwell enclosures throughout the plant except in containment. With the exception of the reactor building, all hose stations are equipped with 100 feet of 1.5-inch hose, in accordance with Section C.6.c of BTP CMEB 9.5-1. By letter dated March 4, 1983, the applicant proposed to deviate from the NRC staff guidelines by utilizing 150 feet of hose to protect all areas of the reactor building. One hundred feet of hose will be pre-connected to the hose outlets. The remaining 50 feet of hose will be connected only if required to suppress a fire in a remote area.

The configuration of the reactor building is such that it is possible to protect most of the floor area with 100 feet of hose. The remaining areas that necessitate the use of the additional 50 feet of hose contain the following systems:

Elevation 606'-10. 5" no safety-related equipment El evati on 572' train systems associated with the emergency core cooling system and the residual heat removal (RHR) heat exchanger Elevation 548' train systems associated with the RHR heat exchanger and-three motor-operated valves Elevation supply for the 522'ower RHR, reactor core isolation cooling (RCIC), and reactor water'leanup systems and the main .steam drain valve Elevation steam 501'ain isolation valve Elevation to motor-operated valves 471'HR piping valves and the dc power supply Elevations 441'nd 444' train systems associated with the RCIC and severe water systems and dc-operated valves Elevation 422'3" no safety-related equipment If a fire damages any of the above-listed equipment, an alternate capability exists in a separate fire area, or compensating actions could be taken, such as manual operation of valves. Consequently, there is no safety significance to the proposed deviation.

The plant water distribution system is capable of supplying hose streams in the reactor building with the required quantity of water and pressure (125 gpm, 65 psi) through 150 feet of hose. In addition, the plant fire brigade is capable of deploying the hose lines quickly enough to suppress postulated fires.

WNP-2 SSER 3 9-4

Based on the above evaluation, the NRC staff concludes the use of 150 feet of hose in the reactor building represents an acceptable deviation from Section C.6.c of BTP CMEB 9. 5-1. This resolves outstanding issue 31.

The applicant has not identified the seismic design of standpipe systems, which is recommended in BTP CMEB 9.5-1, Section C.6.c.(l). For plants for which construction permits were issued prior to July 30, 1976, the guidelines in Appendix A to BTP ASB 9.5-1 have no requirement for seismic design for standpipe systems. Therefore, this is an acceptable deviation from the guidelines of BTP CMEB 9.5-1, Section C.6.c.(1).

9.5. 1.8 Summary of Deviations from BTP CMEB 9.5-1 Five deviations from the guidelines of BTP CMEB 9.5-1 have been identified.

Those items have been approved, and they are (1) control room vent closure (2) seismic design of standpipe systems (3) floor drains in day tank room (4) deletion of a fire suppression system in the following seven plant areas:

remote shutdown room (RC-lX) switchgear room ¹1 (RC-XIV) general floor area (R-1) - elevation 471'-0" general floor area (R-1) - elevation 501'-0" general floor area (R-1) - elevation 522'-0" general floor area (R-1) - elevation 548'-0" general floor area (R-1) - elevation 572'-0" (5) the use of 150 feet of hose at hose stations in the reactor building

9. 5. 1. 9 Concl us i on Based on its evaluation, the NRC staff concludes that the fire protection pro-gram with the accepted deviations listed in Section 9.5. 1.8 above meets the guidelines of BTP CMEB 9.5-1 and GDC 3 and is, therefore, acceptable.

9.5.8 Emergency Diesel Engine Combustion Air Intake and Exhaust System As stated in the SER, the applicant had not adequately addressed potential blockage of the combustion air intake structure as a result of the design worst case dust storm and volcanic ashfall and blockage of the diesel engine exhaust stack as a result of severe meteorological events such as freezing rain, snow, dust storms, heavy rain, and volcanic ashfall. (The evaluation and acceptability of the tornado-missile protection for the diesel engine exhaust stack are addressed in Section 3.5.2 of this supplement.)

In letters dated August 5 and December 28, 1982, the applicant provided information on the capabilities of the diesel engine to operate under adverse meteorological conditions (snow, freezing rain, heavy rain, dust storms, and volcanic ashfall). The applicant stated that if any blockage did occur as a result of adverse meteorological conditions, the diesel engine air intake and

~ WNP-2 SSER 3 9-5

~

~

exhaust structures would only be partially blocked and engine operation would not be affected.. The NRC staff has reviewed the submitted information and concurs with the applicant.

Based on its review, the NRC staff concludes that the emergency diesel engine intake and exhaust system meet the requirements of GDC 2, 4, 5, and 17; meets the guidance of the cited RGs and SRP 9. 5. 8; can perform its design safety function; and meets the recommendations of NUREG/CR-0660 and industry codes and standards. It is, therefore, acceptable. This resolves outstanding issue 18.
