Dear Mr. Parr:

The purpose of this letter is to update and expand upon the information previously provided in the report, "Dynamic Analysis of the Reactor Coolant System for Loss-of-Coolant-Accidents: Salem Nuclear Generating Station I and II which was trans-11 mitted by Reference (a). The information herein was discussed with representatives of Westinghouse and the NRC Core Performance Branch in a tel econ on December 21, 1978.
Attachment A (proprietary) and Attachment B (non-proprietary) contain fuel grid load impact data which supplements the information previously provided in Reference (a). It should be recognized that grid impact loads are calculated using conservative analytical techniques and modeling assumptions. These con-servatisms, which have been discussed in other rlockets such as the North Anna FSAR (Appendix 5A, response to Question 5.71), include: (1) break opening time ~ ... "3Pr}Y-for postulated pip*e ruptures is typ*ically much longer (approximately 20 milli-seconds) than the assumed 1 millisecond break opening time; (2) internal hy-

It is, therefore, unnecessary to apply arbitra*ry factors of safety to the loads resulting from the core evaluations.
The information provided in Table*A-1 represents the grid impact loads for both seismic and blowdown forces calculated by the conservative methods described above. As demonstrated by analyses in \JICAP-9283, "Integrity of the Primary Piping Systems of Westinghouse Nuclear Pow.er Plants during Postulated Seismic Events," transmitted to the NRC by Reference (b), a seismic event will not cause a primary coolant system pipe rupture~ Therefore, the impact loads presented in Table A-1 do not require combination to assure adequate conservatism in the plant design. For your information, a synopsis of WCAP-9283 is provided in Attachment C.

ATTACHMENT C Synopsis of VI-CAP 9283 - "Integrity of the Primary Piping Systems of Westinghouse Nuclear Power Plants During Postulated Seismic Events" WCAP 9283 discusses the simultaneous occurence of seismic and LOCA event and provides a rationale demonstrating that a seismic event will not cause a loss of *coolant accident. The rationale presented by Westinghouse is based upon a detenninistic evaluation of the design margin and quality* of the reactor coolant system while hypothesizing large piping surface flaws. In addition, this report describes a probabilistic structural reliability analysis v1hich supports the above position.
The approach used to develop a rationale for the reactor coolant system integrity incorporates a line of defense methodology at the component level.
The six tiers of protection employed in this approach encompass such tech-niques as non destructive examination during fabrication, inservice inspec-tion, and leak detection. The underlying basis for the integrity of the reactor coolant system is the good engineering practices employed throughout design and construction foll owed by equal diligence during the operating phase.
Deterministic Approach:
The deterministic evaluation of the reactor coolant system is initiated through an examination of the material behavior and stress analysis of components.
Tensile and toughness properties of stainless steel are examined along with fatigue crack growth behavior. In addition, stresses in the reactor coolant system are evaluated based on-;a typical ~/estinghouse four loop plant in a severe seismic zone. Based upon this evaluation, only the reactor vessel outlet nozzle safe end experienced stresses which significantly exceeded the
_yield stresses under combined loadings. This being the case, the elastic-
-plastic behavior of the reactor vessel outlet nozzle safe end is taken into
- account when evaluating fatigue, crack growth, and the potential for localized failure.
Upon completing the review of the material properties, a discussion of quality assurance practice is presented to demonstrate the measures used during con-struction to assure the integrity of reactor coolant piping. Current quality assurance techniques can detect flaws .75 inches in lenqth and .l inches in depth. However, for the purposes of this study, a flaw .25 the thickness in depth and 1.5 the thickness in length at the worst orientation and loading condition is assumed. It should also be recognized that pipe cracks can be identified by leak detection systems sensitive to identify leakage before* such leakage could interfere with the safe operation of the plant .
With the ~ssumption of the piping flaw described above, fatigue crack growth during a seismic event is studied. An elastic analysis is performed
- except for the.reactor vessel outlet nozzle safe end (highest stress location).
In this case a detailed study of elastic-plastic behavior is conducted and two methods (J-integral and equivalent energy fracture methodol-ogies) of plastic.crack.growth evaluation are used. Based upon these evaluations, the reactor vessel outlet nozzle safe end is the only area exhibiting even modest crack grqwth. As a result of these anlayses, it is concluded that a seismic event wil 1 not be the caus.e of a violation of the primary pressure boundary due to cyclic crack growth.
The next phase of t.his study determined the critical flaw size at the worst location (e.g., reactor vessel outlet nozzle safe end). Based upon this evaluation, the critical flaw size at this location is determined to be through wall flaw 25.5 inches in circumference.
Probabilistic Aporoach:
To support the deterministic evaluation described above, probabilistic structural" reliability analyses are performed. Three separate analyses a re described in the. WCAP as follows:
- l. Probability of a crack initiating due to se.ismic induced cyclic fatigue in the ~*1orst location but with no flaw present.
- 2. Probability of a part through crack initiating (ductile tearing) and possibly penet~ating the pipe wall.
- 3. *Probability of~:: seismic event being t'he initiator of a loss of coolant accident assuming a through wall flaw is present.
A*summary of the conservative probabilistic results is provided in the attached Table. These probabilities represent the upper bound and although the input used in these analyses do not support precise prediction of failure probabilities, the calculated numbers can be interpreted as evidence of the adequacy of the design against the specific failure mode in question.
The items in the attached Table are arranged in order of occurrences and may be used directly to estimate the probability of failure for any desired con-ditional assumptions._ 1,he probability of a LOCA caused by an SSE during plant 11fe is 2 x 10 (i.e., the product of the probabilities in Items 1, 3, 4, and 5). Assuming the earthquake occurs and the quarter thickness flaw is present in the sense of the analyses performed, the probability of a LOCA caused by* the SSE is 4 x lo-6 (i.e., l x 10-4 x 0.04). *Considering the prob-ability of the flaw being present, the probability of the LOCA caused by the SSE is 4* x lQ-9,
