Operating Limits The PTLR limits for Beaver Valley Power Station (BVPS) Unit 1 have been prepared in accordance with the requirements of Technical Specification 5.6.4, using the methodology contained in Reference 1.

RCS Pressure and Temperature (PIT) Limits (LCO 3.4.3)

The RCS temperature rate-of-change limits are defined as:

a.

A maximum heatup of 100°F in any one hour period (Reference 2).

b.

A maximum cooldown of 100°F in any one hour period (Reference 2), and

c.

A maximum temperature change of less than or equal to 5°F in any one hour period during inservice hydrostatic testing operations above system design pressure. This rate-of-change limit ensures that thermal gradient stress resulting from temperature change is not induced in the reactor vessel during inservice hydrostatic testing operations above system design pressure.

Beaver Valley Unit 1 5.2 - 1 PTLR Revision 1 O LRM Revision 103

Licensing Requirements Manual 5.2 Pressure and Temperature Limits Report Pressure and Temperature Limits Report 5.2 The RCS PfT limits for heatup, leak testing, and criticality are specified by Figure 5.2-1 and Table 5.2-1. The RCS PfT limits for cooldown are shown in Figure 5.2-2 and Table 5.2-2. These limits are defined in Reference 2.

Consistent with the methodology described in Reference 1, the RCS PfT limits for heatup and cooldown shown in Figures 5.2-1 and 5.2-2 are provided without margins for instrument error. The criticality limit curve specifies pressure-temperature limits for core operation to provide additional margin during actual power production as specified in 10 CFR 50, Appendix G (Reference 5). The heatup and cooldown curves also include the effect of the reactor vessel flange.

The PfT limits for core operation (except for low power physics testing) are that the reactor vessel must be at a temperature equal to or higher than the minimum temperature required for the inservice hydrostatic test, and at least 40°F higher than the minimum permissible temperature in the corresponding PfT curve for heatup and cooldown.

Pressure-temperature limit curves shown in Figure 5.2-3 were developed for the limiting ferritic steel component within an isolated reactor coolant loop. The limiting component is the steam generator channel head to tubesheet region.

This figure provides the ASME Ill, Appendix G limiting curve which is used to define operational bounds, such that when operating with an isolated loop the analyzed pressure-temperature limits are known. The temperature range provided bounds the expected operating range for an isolated loop and Code Case N-640.

- NOTE -

Pressure limits are considered to be met for pressures that are below 0 psig (i.e., up to and including full vacuum conditions) since the resulting PfT combination is located in the region to the right and below the operating limits provided in Figures 5.2-1, 5.2-2, and 5.2-3.

Figures 5.2-1 and 5.2-2 and Tables 5.2-1 and 5.2-2 are based upon analysis of all applicable surveillance capsules per Reference 2. Reference 2 provides an updated surveillance capsule credibility evaluation, updated Position 2.1 chemistry factor values, and an updated fluence evaluation. Therefore, the development of the PfT limit curves (Reference 2) utilized the revised information. Taking into account the updated surveillance data credibility evaluation, the Position 2.1 chemistry factor values, and the fluence analysis summarized in Reference 2, the limiting material for the current BVPS-1 PfT limits continues to be the lower shell plate B6903-1 at 50 EFPY.

Beaver Valley Unit 1 5.2-2 PTLR Revision 10 LRM Revision 103

Licensing Requirements Manual Pressure and Temperature Limits Report 5.2 5.2 Pressure and Temperature Limits Report 5.2.1.2 5.2.1.3 Using the fluence analysis provided in Section 2 of Reference 2, the neutron fluence value for lower shell plate 86903-1 at 50 EFPY is determined to be 5.89 x 1019 n/cm2 (E > 1.0 MeV). Using this updated fluence value along with the updated Position 2.1 chemistry factor value (Table 5.2-4) for this material, the limiting 1/4T and 3/4T adjusted reference temperature (ART) values are 244.0°F and 208.8°F, respectively, at 50 EFPY. Note that for conservatism, PIT limit curves were developed using 1/4T and 3/4T ART values of 244.5°F and 209.5°F, respectively (Reference 2).

Overpressure Protection System (OPPS) Setpoints (LCO 3.4.12)

The power operated relief valves (PORVs) shall each have a nominal maximum lift setting and enable temperature in accordance with Table 5.2-3. The lift setting provided does not impose any reactor coolant pump restrictions.

The PORV setpoint is based on PIT limits which were established in accordance with 1 O CFR 50, Appendix G without allowance for instrumentation error and in accordance with the methodology described in WCAP-14040-A, Revision 4 (Reference 1). The PORV lift setting (Reference 10) shown in Table 5.2-3 accounts for appropriate instrument error.

OPPS Enable Temperature (LCO 3.4.12)

Two different temperatures are used to determine the OPPS enable temperature, they are the arming temperature and the calculated enable temperature. The arming temperature (when the OPPS rendered operable) is established per ASME Section XI, Appendix G. Based on this method, the arming temperature (Reference 10) is 347°F with uncertainty for 50 EFPY.

The calculated enable temperature is based on either a RCS temperature of less than 200°F or materials concerns (reactor vessel metal temperature less than RT Nor + 50°F), whichever is greater. The calculated enable temperature (Reference 10) is 345°F with uncertainty for 50 EFPY.

As the arming temperature is higher and, therefore, more conservative than the calculated enable temperature, the OPPS enable temperature, as shown in Table 5.2-3, is set to equal the arming temperature.

Beaver Valley Unit 1 5.2-3 PTLR Revision 10 LRM Revision 103

Licensing Requirements Manual Pressure and Temperature Limits Report 5.2 5.2 Pressure and Temperature Limits Report 5.2.1.4 5.2.2 The calculation method governing the heatup and cooldown of the RCS requires the arming of the OPPS at and below the OPPS enable temperature specified in Table 5.2-3, and disarming of the OPPS above this temperature. The OPPS is required to be enabled, i.e., OPERABLE, when any RCS cold leg temperature is less than or equal to this temperature.

From a plant operations viewpoint the terms "armed" and "enabled" are synonymous when it comes to activating the OPPS. As stated in the applicable operating procedure, the OPPS is activated (armed/enabled) manually before entering the applicability of LCO 3.4.12. This is accomplished by placing two keylock switches (one in each train) into their "automatic" position. Once OPPS is activated (armed/enabled) reactor coolant system pressure transmitters will signal a rise in system pressure above the OPPS setpoint. This will initiate an alarm in the control room and open the OPPS PORVs.

Reactor Vessel Boltup Temperature (LCO 3.4.3)

The minimum boltup temperature for the Reactor Vessel Flange shall be ;::: 60°F.

Boltup is a condition in which the reactor vessel head is installed with tension applied to any stud, and with the RCS vented to atmosphere.

Reactor Vessel Material Surveillance Program The reactor vessel material irradiation surveillance specimens shall be removed and analyzed to determine changes in material properties. The capsule withdrawal schedule is provided in Table 4.5-3 of the UFSAR. Also, the results of these analyses shall be used to update Figures 5.2-1 and 5.2-2, and Tables 5.2-1 and 5.2-2 in this report. The time of specimen withdrawal may be modified to coincide with those refueling outages nearest the withdrawal schedule.

The pressure vessel material surveillance program (References 3 and 4) is in compliance with Appendix H to 1 O CFR 50, "Reactor Vessel Radiation Surveillance Program." The material test requirements and the acceptance standards utilize the reference nil-ductility temperature, RT NDT, which is determined in accordance with ASME, Section Ill, NB-2331. The empirical relationship between RT NDT and the fracture toughness of the reactor vessel steel is developed in accordance with Appendix G, "Protection Against Non-Ductile Failure," to Section XI of the ASME Boiler and Pressure Vessel Code. The surveillance capsule removal schedule meets the requirements of ASTM E 185-82.

Reference 8 is an NRC commitment made by FENOC to use only the calculated vessel fluence values when performing future capsule surveillance evaluations for BVPS Unit 1. This commitment is a condition of license Amendment 256 and will remain in effect until the NRC staff approves an alternate methodology to perform these evaluations. Best-estimate values generated using the FERRET Code may be provided for information only.

(c) ART Nor values are the measured 30 ft-lb shift values. The Beaver Valley Unit 1 ART Nor values for the surveillance weld data are adjusted by a ratio of 1.06. Pre-adjusted values are listed in parentheses, and were taken from Table 4-1 of Reference 2. NOTE: Per Regulatory Guide 1.99, Revision 2 (Reference 7), section 2.1 "Radiation Embrittlement of Reactor Vessel Materials," the vessel weld chemistry factor is divided by the surveillance weld chemistry factor to obtain a ratio factor to multiply the ART NDT values by to obtain adjusted ART NDT values.

(d) i1RT Nor values are the measured 30 ft-lb. shift values. i1RT Nor values for the surveillance weld data are adjusted first by the difference in operating temperature then using the ratio procedure to account for differences in the surveillance weld chemistry and the beltline weld chemistry. Pre-adjusted values are listed in parentheses, and were taken from Tables 4-2 of Reference 2 and Table A-5 of Reference 9. The temperature adjustments for each capsule were calculated from the data in Table 5.2-4b and the average plant irradiation temperature for BV-1. The St. Lucie Unit 1 L1RT Nor values for the weld data are adjusted by a ratio of 1.17. The Millstone Unit 2 and Fort Calhoun L1RT Nor values were not adjusted since the ratio was less than 1.00; therefore, a conservative value of 1.00 was used. (e) The St. Lucie Unit 1 and Millstone Unit 2 surveillance data is deemed credible per Appendix D of Reference 2; however, a full margin term should be utilized for conservatism when this data is applied as a result of the unclear identification of the Millstone Unit 2 weld specimen heat numbers.
