• FITZPATRICK Gell LEAD TEST ASSEMBLY LICENSING 1.- BACKOROUND The Power Authority of the State of New York (The Authority) plans to load four (4) Lead Test Assemblies (LTAs) as part of James A. FitzPatrick Nuclear Power Plant (JAFNPP) Reload 9 Cycle 10 during the 1990 refueling outage. These fuel bundles, also referred to as GEli LTAs, are planned to be in operation as part of a joint program with the General Electric Company (GE).

This report contains information that is to be provided to the Nuclear Regulatory Commission (NRC) to comply with the Reference 1 letter which provides guidelines to be followed to licer.se LTAs. Included in this report are a description of the GEli LTAs, a discussion of the applicability of approved methods to the licensing analyses, a description of the objectives of the LTA program, and an outline of the kinds of measurem-nts planned for the LTAs.

2. LTA DESCRIPTION A descripion of the GE11 LTAs is contained in Attachment 2. Table 1 of Attachment 2 provides LTA design s.aecifications. Fuel bundle and fuel rod descriptions for the LTAs are provided in Figures 1 anc 2 of Attachtnent 2.

3. LICENSING ANALYSES l The GEli LTAs have been analyzed using the NRC approved methods described in Reference '

2. Rese methods are fully capable of analyzing all of the LTA features and the results demonstrate that the LTAs will operate within all design and safety limits of Reference 2. Cycle specific analyses - 1 have been performed for JAFNPP Reload 9 Cycle 10 to establish fuel operating limits for the LTAs and to ensure that the core loading has been designed such that the LTAs will not be the most 1

limiting fuel assemblies at any time during Cycle 10. Results of these analyses are contained in Reference 3. Furthermore, licensing analyses will be performed for the LTAs for each cycle of their operation,wherein the effect of the LTAs is considered for each of the appropriate licensing events and anticipated operational occurrences (AOOs) to establish appropriate reactor core thermal l limits for operation.

He application of approved methods to analyze events and accidents whose results could be l affected by the LTA's design is discussed below. Since the analysis of the LTAs using the approved l l methods meets the approved criteria, it can be concluded that no unreviewed safety question exists.

3.1 Core Wide AOOs Current approved methods described in Reference 2 are considered appropriate to determine the impact of the core wide AOOs on the LTAs. Appropriate MCPR hmits are established to ensure safe operation of the LTAs based on the results in Reference 3.

. 3.2 Localized AOOs

.[

Approved methods are considered adequate to evaluate core response to a Rod Withdrawal Error (RWE), since nuclear inputs are available to represent the LTAs discretely. MCPR results for the LTAs are provided in Reference 3.

' An evaluation was performed to estimate the effect on CPR of the Fuell.cading Error (Rotated Bundle). The evaluation demonstrates that the change in CPR for this event is bounded by that used to establish the Operating Limit MCPR (OLMCPR) for the LTAs, and therefore a Rotated Bundle Error will not result in violation of the OLMCPR.

3.3 Control Rod Droo Accident (CRDA)

Due to the similarities in nuclear characteristics between the LTAs and approved GE fuel designs, the Reference 2 methodology is applicable to the LTAs. Operation with the LTAs will not result in exceeding CRDA acceptance criteria.

3.4 Loss-of Coolant Accident and ECCS ,

Current approved emergency core cooling system (ECCS) models, extended to the 9x9-

. geometry, have been conservatively applied to the analysis of the LTAs. The resulting LTA Maximum Average Planar Linear Heat Generation Rtte (MAPLHOR), peak clad temperature and local oxidation fraction values are presented in References 3 and 4.

3.5 Refueline Accident The impact of the LTAs on the assumptions and consequences of a refueling accident, as documented in the JAFNPP FSAR and m Reference 2, has been evaluated. The radiological consequences are conservatively bounded by the current FSAR analyses.

3.6 Core Stability The LTA design maintains core and channel stability equivalent to that of the BP8x8R and GE8x8EB designs according to current approved GE methods. As noted in Reference 3, GE SIL 380 recommendations have been included in the JAFNPP operating procedures and/or Technical Specifications and JAFNPP will comply with the recommendations contained in NRC Bulletin No. 88 07, Supplement 1. Therefore, no JAFNPP Reload 9 Cycle 10 stability analysis is required.

3.7 Shutdown Marcin ,

Analyses performed with approved methods for the LTAs in the JAFNPP Reload 9 Cycle 10 core have shown that the minimum cold shutdown margin (results presented in Reference 3)is greater than or equal to the design criteria identified in Reference 2 which, therefore, assures that all Technical Spectfication shutdown margin requirements are satisfied.

4. LTA PROGRAM OBJECTIVES The purpose of the Gell LTA Program is to obtain test data to verify that fuel bundles with the design features given in Section 2 perform satisfactorily in service, prior to use of those features on a production basis.

. -- 5. - LTA MEASUREMENTS As currently envisioned, measurements on the LTAs consist of preirradiation characterization of

_ fuel pellets, clad tubing, fuel rods and fuel bundles. At subsequent refueling outages, the scope of.

inspections consist of overall bundle visual examinations, channel bow and bulge measurements, bundle and rod length measurements, rod integrity and profilometry measurements, and corrosion thickness measurements. The extent of such measurement and testmg will be governed by the need to minimize the impact of such testing on refueling outage critical path, the amount of inspections being performed on similar features at other reactor sites, and by the degree of technical interest in implementing the design changes demonstrated in the LTA.

Results obtained from this LTA Program will be summarized in a timely manner in subsequent General Electric Fuel Experience Reports.

AFFIDAVIT ,

l I, Janice S. Charnley, being duly sworn, depose and state as follows.

1. I am Manager, Fuel Licensing, General Electric Company, and have been delegated the function of reviewing the information described in paragraph 2 which is sought to be with -

held from public disclosure and have been authorized to apply for its withholdmg.

?.. The information sought to be withheld is the attached GEli LTA Fuel Bundle Description l Report for The Power Authority of the State of New York James A. FitzPatrick Nuclear l' Power Plant, January 1990.

3. In designating material as proprietary, General Electric utilizes the definition of proprietary information and trade secrets set forth in the American Law Institute's Restatement of Torts, Section 757. This definition provides:

"A trade secret may consist of any formula, pattern, device or compilation of infor-mation which is used in one's business and which gives him an opportunity to obtain an advantage over competitors who do not know or use it.... A substantial element of secrecy must exist, so that, except by the use of improper means, there would be difficulty in acquiring information.... Some factors to be considered in determining whether given information is one's trade secret are: (1) the extent to which the information is known outside of his business; (2) the extent to which it is known by employees and others involved in his business; (3) the extent of mea-sures taken by him to guard the secrecy of the information; (4) the value of the in-formation to him and to his competitors;(5) the amount of effort or money ex-pended by him in developing the information; (6) the case or difficulty with which the information could be properly acquired or duplicated by others."

4. Some examples of categories of information which fit into the definition of proprietary infor-mation are:

a. Information that disclosed a process, method or apparatus where prevention of its use by General Electric's competitors without license from General Electric constitutes a competitive economic advantage over other companies;

b. Information consisting of supporting data and analyses, including test data, relative to a process, method or apparatus, the application of which provide a competitive economic advantage, e.g., by optimization or improved marketability;

c. Information which, if used by a competitor, would reduce his expenditure of resources

- or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality or licensing of a similar product;

d. Information which reveals cost or price information, production capacities, budget levels or commercial strategies of General Electric, its customers or suppliers;

~

e. Information which reveals aspects of past, present or future General Electric cus-tomer funded development plans and programs of potential commercial value to.

General Electric;

f. Information which discloses patentable subject matter for which it may be desirable to obtain patent protection; 1

g. Information which General Electik must treat as proprietary according to agreements  !

with other parties.

5. Initial approval of r,,roprietary treatment of a document is typically made by the Subsection ~ i manager of the origmating component, who is most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge. Access to such documents within the Company is limited on a "need to know" basis and such documents are clearlyidentified as proprietary.

6. The procedure for approval of external release of such a document ty)ically requires review by the Subsection Manager, Project manager, Principal Scientist or ot ier equivalent author-ity, by the Subsection Manager of the cognizant Marketite function (or delegate) and by the Legal Operation for technical content, competitive effect and determination of the accuracy of the proprietary designation in accordance with the standards enumerated above. Disclo-sures outside General Electric are generally limited to regulatory bodies, customers and po-tential customers and their agents, suppliers and licensees, and then only with appropriate protection by applicable regulatory provisions or proprietary agreements.

7. The document mentioned in paragraph 2 above has been evaluated in accordance with the above criteria and procedures and has been found to contain information which is propri-etary and which is customarily held in confidence by General Electric.

8. The document mentioned in paragraph 2 above is classified as proprietary because it contains details concerning current General Electric fuel designs which were developed at considerable expense to General Electric, which are not available to other parties.

9. The information to the best of my knowledge and belief has consistently been held in confi-dence by the General Electric Company, no public disclosure has been made, and it is not available in public sources. All disclosures to third parties have been made pursuant to .

regulatory provisions or proprietary agreements which provide for maintenance of the infor- i mation in confidence.

10. Public disclosure of the information sought to be withheld is likely to cause substantial harm to the competitive position of the General Electric Company and deprive or reduce the availability of profit making opportunities because it would provide other parties, including competitors, with valuable information regarding current General Electric fuel designs which  ;

were obtained at considerable cost to the General Electric Company. The manpower, computer and manufacturing resources expended by General Electric to develop the current fuel designs are valued at approximately $8 million. In addition, the development of

. individual bundle and lattice designs required over 120 man hours and approximately $20,000 in computer resources.
