Therefore, prior to performance of the test, the Main Steam Line Radiation Monitor Trip Level Setpoint will be raised to fthree times the increased radiation levels. The test will be conducted at power levels >80% of normal rated power. During controlled power reduction, the setpoint will be readjusted prior to going below 20% rated power without the setpoint change, control rod withdrawal will be prohibited until the necessary trip setpoint adjustment is made.

At pressures below 785 psig, the core elevation pressure drop is greater than 4.56 psi for no boiling in the bypass region. At low powers and flows, this pressure drop is due to the elevation pressure of the bypass region of the core. Analysis shows that for bundle power in the range of 1-5 htWt, the channel flow will never go below 28 x 108 lb/hr. This flow results from the pressure differential between the bypass region and the fuel channel. The pressure differential is primarily a result of changes in the elevation pressure drop due to the density difference between the boiling water in the fuel channel and the non-boiling water in the bypass region. Full scale ATLAS test data taken at pressures from 0 to 785 psig indicate that the fuel assembly critical power at 28 x 108 lb/hr is approximately 3.35 h1Wt. With the desir,n peaking factors, this corresponds to a core thermal power of more thaa 50%. Thus, a core thermal power limit of 25% for reactor pressures below 785 psig is conservative.

L Attachment II to JPN-88-037 SAFETY EVALUATION Page 3 of 7 II. PURPOSE OF TIIE PROPOSED CIIANGES The purpose of the proposed changes is to support plant start-up and operation after the Reload 8/ Cycle 9 refueling outage. During this outage,184 fuel bundles are to be removed from the reactor core and replaced by new fuel. The changes to the Technical Specifications involve deleting specifications associated with the discharged fuel and with Cycle 8 specific analyses, and replacing them with ones which are appropriate for the new fuel and are based on Cycle 9 specific analyses.

To simplify the discussion of the proposed changes, the 16 individual changes on 14 technical specification pages are grouped into three categories:

A) Changes to reflect the removal of fuel type P8DRB299 from the reactor core and its replacement with fuel types BD336A and BD339A; B) Changes to reflect the Cycle 9 specific transient and accident analyses, use of the GEXL-PLUS critical power correlation, and the new fuel cladding integrity safety limit; C) Miscellaneous changes (e.g., correction of a typographical error and clarification of I text). I CATEGORY A 184 fuel bundles are to be removed from the reactor core and placed in the spent fuel pool for storage. Replacing these fuel bundles in the core will be 152 bundles of fuel type BD336A and 32 bundles of fuel type BD339A. The two new fuel types are General Electric's GE8X8EB design and are mechanically identical to the Reload 7 fuel. The U 2ss enrichment and gadolinium content are varied to support cycle specific needs and to improve fuel economy.

The changes to the Technical Specifications involve changes to the List of Figures, MAPLHGR figures and reactor design sections. The following changes fall into this category:

a, b,1, m, n, o, and p.

CATEGORY B Cycle 9 specific transient analyses, performed by General Electric Co. (GE), determine the operating limits for Cycle 9. The analyses were performed with GE's GEXL-PLUS thermal correlation and the revised safety limit MCPR of 1.04. The results of these analyses are contained in Reference 3 and are included in this application as Attachment II.

The changes to the Technical Specifications involve changes to the MCPR sections and Base;,

MCPR operatin8 limit ta'Ule, the MCPR figure, and the K g curves. The following changes fall into this category: c, d, e, f, h, j, and k.

CATEGORY C One typographical error (the misspelling of the word "signal") is corrected. Change [i] to the Technical Specifications reflects this correction.

In NRC Inspution Report 50-333/M-05 (Reference 4), an NRC inspector considered the Technical Specification Bases for ll.l.B to be unclear. This section discusses the reactor thermal power limit when the reactor pressure is below 785 psig. The Authority committed to

Attachment II to JPN-88-037 SAFETY EVALUATION Page 4 of 7 submit a revision to this bases section in this reload application submittal (Reference 5).

Change [g] to the Technical Specifications is that revision.

Cleed pages vii and 123, contained in Attachment I to this application, carry over errors wL. currently exist in the Technical Specifications. The Authority has previously submitted an application for amendment to the Technical Specifications to correct these and other administrative and typographical errors. (Reference 6)

III. IMPACT OF TIIE PROPOSED CIIANGES The overall impact of the proposed changes would be to allow start-up and operation of the FitzPatrick Nuclear Power Plant following the upcoming Reload 8/ Cycle 9 refueling outage.

This outage is entrently scheduled to begin in late August 1988 and last until early November.

To simplify the discussion of the impact of each of the individual changes, this evaluation will address the three categories of changes that were previously defined in Section II above.

CATEGORY A The 184 fuel bundle of Reload 8 are of fuel bundle type GE8X8EB. 152 of these bundles are designated BD336A, and the 32 others are designated BD339A. These fuel bundles incorporate the design features described in Reference 7.

The fuel to be added in Reload 8 is similar to that added in Reload 7 in that it contains several lattice types of varying gadolinium content. To determine the proper h1APLIIGR value for a particular axial location in a fuel bundle, ,he h1APLIIGR tables contained in Reference 8 will be programmed into the plant process computer and backup computer system. When hand calculations are necessary, the most limiting enriched uranium lattice hfAPLIIGR value is applicable. The exposure dependent limiting hfAPLIIGR values are shown in Figures 3.5-13 and 3.5-14 on pages 135k and 1351 for fuel types BD336A and BD339A respectively. The tables used to generate these figures are included in Attachment 111.

The hfAPLilGR curve for fuel type P8DRB299 (Figure 3.5-10 on page 135h) is deleted since all fuel bundles of this tyra are being removed from the core.

CATEGORY B The changes in this category reflect the Cycle 9 specific transient and accident analyses performed by General Electric Co. for FitzPatrick. The results of these analyses are contained in Reference 3 and are included in this application as Attachment III.

The analyses were performed with GE's GEXL-PLUS critical heat flux correlation. This correlation provides a more accurate determination of the critical heat flux. Implementation of the GEXL-PLUS correlation increases plant fuel cycle efficiency and operating flexibility without reducing the current safety margins (Reference 9). Use of the GEXL-PLUS correlation was approved generically for GE fueled BWRs by the NRC in Amendment 15 to Reference 7.

The analyses required for Cycle 9 were performed with the revised safety limit minimum critical power ratio (hfCPR) of 1.04, instead of the previous safety limit hfCPR of 1.07. The safety limit hiCPR of 1.04 is a result of the statistical analyses performed by GE for reactor cores which are operated with a second successive reload of high enrichment, high R-factor,

Attachment 11 to JPN-88-037 l SAFETY EVALUATION  ;

Page 5 of 7 l 8x8 fuel. The analyses associated with the new safety limit predict that 99.9% of tne fuel rods in the core would avoid boiling transition. This is the same criteria that was previously applied to the safety limit of 1.07 and therefore, the change does not reduce any margin of safety. Use of the revised MCPR safety limit of 1.04 was generically approved by the NRC in Amendment 14 to Reference 7.

CATEGORY C Correction of the misspelling of "signal" has no impact on plant operation and is being made to correct the error.

Clarification of the Bases for Ql.l.B. has no impact on the plant since no change is being made to the safety limit power level for the Core Thermal ?ower Limit when the reactor pressure is below 785 psig. The Authority concurs with the NRC that the existing Bases section is unclear. The proposed replacement to this section was developed with the assistance of General Electric Co. It attempts to more clearly describe the theoretical and experimental bases for the existing power level limit than the existing paragraph.

IV. EVALUATION OF SIGNIFICANT IIAZARDS CONSIDERATION Operation of the FitzPatrick Plant in accordance with the proposed Amendment would not involve a significant hazards consideration as stated in 10 CFR 50.92 since it would not:

1. involve a significant increase in the probabliity or consequences of an accident previously evaluated. NRC approved methodologies and codes have been used to perform all analyses concerning the General Electric Co. fuel to be loaded at this refueling (Reference 7). The fuel design has been reviewed and approved for use at FitzPatrick under the constraints and methodologies detailed in Reference 7.

There are no unique aspects of this fuel or its application which have not i undergone prior NRC review and approval. The refueling of the FitzPatrick l reactor and Cycle 9 operation does not increase the probability or consequences of any accident previously evaluated.

2. create the possibility of a new or different kind of accident from any accident previously evaluated. Refueling the FitzPatrick reactor is a periodic evolution performed in accordance with appropriate procedures and controlled by the Technical Specifications. The fuel bundles inserted as Reload 8 are mechanically identical to those inserted in Reload 7 and will not create the possibility of a new or different type of accident. The nuclear characteristics of the individual fuel bundles and the core loading pattern have been fully analyzed by the General Electric Co. and do not create the possibility of a new or different type of accident. The assemblies have been fully reviewed and approved for use in power reactors by the NRC (Reference 7).
3. involve a significant reduction in a margin of safety. The analyses performed in support of this reload assure maintenance of all existing margins of safety. These analyses have resulted in core wide (MCPR) and bundle specific (MAPLilGR) limits for General Electric Co. fuel which, when applied to the reloaded core, assure operation within the design criteria previously approved in Reference 7.

The revised MCPR safety limit provides the same margin of safety as the previous

Attachment II to JPN-88-037 SAFETY EVALUATION Page 6 of 7 safety limit in preventing boiling transition. This change was previously approved by the NRC for use in GE fueled BWR reactors (Reference 7).

In the April 6,1983, FEDERAL REGISTER (48FR14870), the NRC published examples of license amendments that are not likely to involve significant hazards considerations. Example number (iii) of that list is applicable to this proposed chance and states in part:

For a nuclear power reactor, a change resulting from a nuclear reactor core reloading, if no fuel assemblies significantly different from those found previously acceptable to the NRC for a previous core at the facility in question are involved.

V. Ih1PLEh1ENTATION OF TIIE PROPOSED CIIANGE Implementation of the proposed changes will not impact the ALARA or Fire Protection Programs at FitzPatrick, nor will the chan8es impact the environment.

VI. CONCLUSION The change, as proposed, does not constitute an unreviewed safety question as defined in 10 CFR 50.59. That is, it:

A. will not change the probability nor the consequences of an accident or malfunction of equipment important to safety as previously evaluated in the Safety Analysis Report; B. will not increase the possibility of an accident or malfunction of a different type from any previously evaluated in the Safety Analysis Report; C. will not reduce the margin of safety as defined in the basis for any technical specification; D. does not constitute an unreviewed safety question; and E. involves no significant hazards consideration, as defined in 10 CFR 50.92.
