2. BASES PRESSURE TEMPERATURE LIMITS All components in the Reactor Coolant System (RCS) are designed to withstand the effects of cyclic loads due to system temperature and pressure changes. These cyclic loads are induced by normal load transients, reactor trips and startup and shutdown operations. During RCS heatup and cooldown, the temperature and pressure changes must be limited to be consistent with design assumptions and to satisfy stress limits for brittle fracture.

During heatup, the thermal gradients through the reactor vessel wall produce thermal stresses which are compressive at the reactor vessel inside surface and which are tensile at the reactor vessel outside surface. Since reactor vessel internal pressure always produces tensile stresses at both the inside and outside surface locations, the total applied stress is greatest at the outside surface location. However, since neutron irradiation damage is larger at the inside surface location when compared to the outside surface, the inside surface flaw may be more limiting. Consequently for the heatup analysis both the inside and outside surface flaw locations must be analyzed for the specific pressure and thermal loadings to determine which is more limiting.

During cooldown, the thermal gradients through the reactor vessel wall produce thermal stresses which are tensile at the reactor vessel inside surface and which are compressive at the reactor vessel outside surface. Since reactor vessel internal pressure always produces tensile stresses at both the inside and outside surface locations, the total applied stress is greatest at the inside surface location. Since the neutron irradiation damage is also greatest at the inside surface location, the inside surface flaw is the limiting location. Consequently, only the inside surface flaw must be evaluated for the cooldown analysis.

The fracture toughness properties of the ferritic material in the reactor vessel were determined in accordance with the NRC Standard Review Plan, ASTM E185-73 and in accordance with additional reactor vessel requirements.

The properties are then evaluated in accordance with Appendix G of the 1983 Edition of Section XIX of the ASME Boiler and Pressure Vessel Code and the additional requirements of 10CFR50, Appendix G and the calculation methods described in Westinghouse Report GTSD-A-1.12, "Procedure for Developing Heatup and Cooldown Curves".

B3. l. 2 Amendment Nos. and TCGPTL.PLA

The heatup and cooldown limit curves, Figures 3.l-la, 3.1-1b, and 3.1-1c are composite curves prepared by determining the most conservative case with either the inside or outside wall controlling, for any heatup rate up to 100 degrees F per hour and cooldown rates of up to 100 degrees F per hour. The heatup and cooldown curves were prepared based upon the most limiting value of predicted adjusted r'eference temperature at the end of the applicable service period (20 EFPY).

The reactor vessel materials have been tested to determine their initial RT ; the results of these tests as well as other material erties are shown in Tables B3.1-1 and B3.1-2. Reactor operation and resultant fast neutron (E greater than 1 MeV) irradiation can cause an increase in the RTN T. Therefore, an adjusted reference temperature, based upoR the fluence and chemistry factors of the limiting Reactor Vessel material has been predicted using Regulatory Guide 1.99, Revision 2, dated May 1988 (the latest accepted NRC methodology), "Radiation Embrittlement of Reactor Vessel Materials". The heatup and cooldown limit curves of Figures 3.1-1a, 3.1-1b, and 3.1-1c include predicted adjustments for this shift in RTNDT at the end of the applicable service period The actual shift in RT D of the vessel material will be established periodicallPduring operation by removing and evaluating, in accordance with ASTM E185-73 and 10CFR Appendix H, reactor vessel material irradiation surveillance specimens installed near the inside wall of the reactor vessel in the core area. The surveillance specimen withdrawal schedule is shown in Specification 4.20.1. Since the neutron spectra at the irradiation samples and vessel inside radius are essentially identical, the measured transition shift for a sample can be applied with confidence to the adjacent section of the reactor vessel.

Since the limiting beltline material (Intermediate to Lower Shell Circumferential Weld) in Unit 3 and 4 is identical, the RV surveillance program was integrated and the results from capsule testing is applied to both Units. The surveillance capsule "T" results from Unit 3 (WCAP 8631) and Unit 4 (SWRI 02-4221) and the capsule "V" results from Unit 3 (SWRI 06-8576) were used with the methodology in Regulatory Guide 1.99 Revision 2 to provide limiting material properties information for generating the heatup and cooldown curves in Figures 3.1-1a, 3.1-lb, and 3.1-1c. The integrated surveillance program along with similar identical reactor vessel design and operating characteristics allows the same heatup and cooldown limit curves to be applicable at both Unit 3 and Unit 4.

B3.1-2a Amendment Nos. and TCGPTL.PLA

The limitations imposed on the pressurizer heatup and cooldown rates and spray water temperature differential are provided to assure that the pressurizer is operated within the design criteria assumed for the fatigue analysis performed in accordance with the ASME Code requirements.

These corrections involved subtracting the incremental change in the %DC associated with a core condition of iLll rods inserted (most positive hIDC) to an all rods withdrawn condlfi(xl and 4 conversion for the rate of change ot moderator density with temperture at RR,TEO THERMAL, POWER conditims R3. l -) Amendment Nos. ~d
