Denton, Director Office of Nuclear Reactor Regulation United States Nuclear Regulatory Commission Washington, DC 20555 SHEARON HARRIS NUCLEAR POWER PLANT UNIT NO ~ 1 DOCKET NO. 50-400 BORON INJECTION TANK CONCENTRATION REDUCTION

Dear Mr. Denton:

Carolina Power & Light Company hereby submits information to justify reducing the boron concentration in the Boron Injection Tank (BIT) to zero ppm (Attachment 1). Reducing the boron concentration in the BIT eliminates the need for heat tracing of the system. This will translate into considerable maintenance savings and a slight decrease in plant electrical load.

Additionally, all technical specifications concerning BIT boron concentrations, temperatures, and associated surveillance/maintenance, exclusive of the Refueling Mater Storage Tank, will be eliminated.

Carolina Power & Light Company is proceeding to implement the subject design modifications. Therefore, your prompt review and approval of this submittal is appreciated. Changes to the Final Safety Analysis Report will be submitted in a future amendment. If you have any questions, please contact Mr. S. R. Zimmerman at (919) 836-6242.

I ATTACHMENT I RESULTS OF THE REPORT FOR THE BIT CONCENTRATION REDUCTION/BIT ELIMINATION STUDY FOR THE SHEARON HARRIS NUCLEAR POWER PLANT BY WESTINGHOUSE ELECTRICAL CORPORATION FOR CAROLINA POWER 6 LIGHT COMPANY 1

(356GAS/ccc)

Introduction Westinghouse has developed improved analytical techniques which allow a reduction in the Boron Inj ection Tank (BIT) concentration or bypassing/elimination of the BIT, which removes it from the Safety Inj ection System. This report provides information to substantiate a reduction in the BIT boron concentration for the Shearon Harris Nuclear Power Plant (SHNPP).

Back round on Existi Desi n and Anal sis The BIT is a component of the Safety Injection System whose sole function is to provide concentrated boric acid to the Reactor Coolant System (RCS) to mitigate the consequences of postulated steamline break accidents. Although the BIT acts to mitigate steamline breaks of various sizes occurring from any power level, the cases which serve as the Westinghouse steamline break licensing basis and which define the existing requirements on the minimum BIT boron concentration are as follows:

For the "hypothetical" steamline break; i.e., double-ended rupture of a main steamline, the radiation releases must remain within the requirements of 10 CFR 100. This is the ANSI N18.2 criterion for Condition IV events. The SHNPP conservatively meets this criterion by demonstrating that the DNB design basis, the criterion typically used for Condition II events, is met.

For the "credible" steamline break; i.e., the failure open of a single steam generator relief, safety, or turbine bypass valve, the radiation releases must remain within the requirements of 10 CFR 20. This is the ANSI N18.2 criterion for Condition II events. Westinghouse has conservatively demonstrated compliance with this criterion for the SHNPP by demonstrating that no return to criticality is achieved.

Descri tion of the Anal ses The only accident analyses which are significantly affected by BIT boron concentration reduction are the steamline break transients. These transients are affected with respect to both core integrity and mass and energy release to containment. For the SHNPP, the system was analyzed assuming that the BIT remains installed, without heat tracing, and with the boric acid concentration reduced to zero ppm. This combination provides the most limiting case for the analyses.

This case is considered because it allows elimination of the presently specified heat tracing associated with the BIT. Additionally, all technical specifications concerning BIT concentrations, temperatures, and associated surveillance, exclusive of the Refueling Water Storage Tank (RWST), can be eliminated.

(356GAS/ccc)

Core Inte rit Anal sis The following cases were reanalyzed for the reduction in the BIT boron concentration with respect to the core integrity:

"Hypothetical" steamline break, with and without off-site power available, for the largest double-ended rupture of a steam pipe (1.4 ft2).

"Credible" steamline break, with off-site power available, for the largest single failed open steam generator relief, safety or steam dump valve.

For the hypothetical breaks, the same criteria is applied as that applied in the FSAR. That is, for the most severe Condition IV break, Westinghouse concluded that the radiation releases were within the requirements of 10 CFR 100 by demonstrating that the DNB design basis is met. The steamline break dose calculations performed for the FSAR use a conservative fuel failure level of one (1) percent. The core analyses however show that no consequential fuel failures are anticipated.

The credible steamline break analysis is performed using a new criterion whereby the plant may return to criticality, but no damage may occur to the fuel. This constitutes a relaxation of the conservative internal Westinghouse criterion for Condition II events. This new criterion is in compliance with the criteria used by the NRC and ANS which require that releases during steamline .break accidents remain within the limits set forth in 10 CFR 20. If it is assured that there is no consequential fuel damage, the limits stipulated in 10 CFR 20 are met with a return to criticality.

Anal sis Method In this analysis, the system transient parameters; i.e., Reactor Coolant System (RCS) pressure, temperature, steam flow, core boron concentration and core power were calculated by using the LOFTRAN System Transient Analysis computex code (Reference 1). This computer code includes models of the reactor core, protection systems, and engineered safeguards system. The change in Safety In) ection System initial concentration and temperatures were introduced into the analysis in the LOFTRAN code.

For the "hypothetical" breaks, the plant is initially assumed to be at hot zero power at the minimum required shutdown margin. Following the break, the RCS temperatures and pressures decrease rapidly, and in the presence of a large End of Life (EOL) moderator coefficient of reactivity, the reactor returns critical with the rods inserted, assuming the most reactive RCCA in the fully withdrawn position. The reactor power increases at a decxeasing rate until boron from the Safety In) ection System reaches the coxe and begins to offset the positive reactivity insertion caused by the cool-down.

The core is subsequently brought subcritical with boron inj ection, aided by the abatement and eventual termination of steam flow from the faulted steam generator.

(356GAS/ccc)

The attached Figures 1 through 6 show the transient behavior for the hypothetical breaks. A comparison of these figures with the current FSAR figures reveals only small changes in RCS parameters, with the single exception of core power, which is understandably higher for the cases without the BIT. The effect of the boron on the total reactivity is both delayed and damped in the attached figures because the Safety Injection System must purge more water before inj ecting boron in the cold leg and the fact that the boron source (RWST) is both colder and of a lower boron concentration. This causes the power to initially rise to a higher peak due to the delay and to subsequent decay at a slower rate after the boron reaches the core.

Additionally, with the BIT assumed to be at zero ppm concentration, the BIT acts as a dilution volume for the borated water being inj ected from the,RWST, thereby further delaying the effectiveness of the RWST.

After verifying that the case assuming full reactor coolant flow will remain limiting relative to the case without off-site power, DNB analyses were performed using the same design verification procedure that is used for the FSAR cases. The DNB analyses show that the DNB design basis is met, and that no consequential fuel failures are anticipated.

The dose evaluation, which is performed assuming one (1) percent failed fuel, continues to demonstrate that the Condition IV accident criteria are satisfied.

Attached Figures 7 and 8 depict system transient parameters for the Condition II steamline break in the FSAR. This Westinghouse criterion assures that the DNB design basis is met in a very conservative manner. In order to substantiate reduction of the boron concentration in the BIT, the Westinghouse criterion was relaxed to allow a subsequent return to power for the Condition II transients, but in order to meet, the 10 CFR 20 dose requirements, the DNB design basis had to be met. Figure 7 shows that criticality is attained for the assumed BIT elimination. DNB analyses for this case show that the DNB design basis is met and no fuel failures are predicted. This conclusion is also consistent with the conclusion drawn on the Condition IV breaks, since no violation of the DNB design basis was calculated for the more extreme Condition IV, double-ended ruptures.

Thus, calculations have been performed for the SHNPP which show that for the present NRC criterion for Condition II events, Carolina Power & Light Company (CP&L) may reduce the boron concentration in the BIT to zero ppm. The same criteria for the Condition IV steamline breaks that was used in the FSAR can be met for this elimination.

Hass and Ener Releases A spectrum of break sizes at various power levels were reanalyzed for the

'eduction in the BIT boron concentration to zero ppm. The breaks analyzed are listed in Table l.

Anal sis Method The mass and energy release was analyzed by Westinghouse using the MARVEL Code (Reference 2). The analysis assumptions are essentially identical to the analysis described in the FSAR with the exception of the temperature and boron concentration of the BXT. The mass and energy releases for the break cases indicated in Table 1 are provided as Appendix A.

Based upon the Westinghouse analysis, a new containment pressure and temperature analysis was completed. The results of this analysis are in Appendix B to this report. The new maximum peak containment temperature is 379'F which is 3'igher than the present FSAR value, but still within the 380'P values used for equipment qualification. Por the pressure, the worst case was found to be the zero power, full double-ended break with a single failure of a feedwater isolation valve. This is different from the present FSAR worst case which is at 30 percent power. The new maximum peak containment pressure is 39.1 psig which is higher than the present FSAR value of 35.4 psig, but well within the containment design limit of 45 psig. CPGL has reviewed and concluded that the new containment peak temperature and pressure, as they related to balance-of-plant design, are acceptable.

Conclusion As a result of these analyses, CPGL proposes to reduce the boron inj ection tank boron concentration to zero ppm. FSAR changes resulting from these analyses will be incorporated in a future amendment to the FSAR.
