REACTOR COOLANT SYSTEM BASIS PRESSURE/TEMPERATURE LIMITS (Continued) 1.

The reactor coolant temperature and pressure and system heatup and cooldown rates (with the exception of the pressurizer) shall be limited in accordance with Figures 3.4-2 to 3.4-4 for the service period specified thereon:

a.

Allowable combinations of pressure and temperature for specific temperature change rates are below and to the right of the limit lines shown.

Limit lines for cooldown rates between those presented may be obtained by interpolation; and b.

Figures 3.4-2 to 3. 4-4 define limits to assure prevention of non-ductile failure only.

For normal operation, other inherent plant characteristics, e.g.

pump heat addition and pressurizer heater

capacity, may limit the heatup and cooldown rates that can be achieved over certain pressure-temperature ranges.

2.

These limit lines shall be calculated periodically using methods provided

below, 3.

The secondary side of the steam generator must not be pressurized above 200 psig if the temperature of the steam generator is below 70'F, 4.

The pressurizer heatup and cooldown rates shall not exceed 100'F/h and 200'F/h, respectively.

The spray shall not be used if the temperature difference between the pressurizer and the spray fluid is greater than 320 F, and 5.

System preservice hydrotests and inservice leak and hydrotests shall be performed at pressures in accordance with the requirements of ASME Boiler and Pressure Vessel

Code,Section XI.

The properties are then evaluated in accordance with Appendix G of the 1983 Edition of Section III of the ASME Boiler and Pressure Vessel Code and the additional requirements of 10 CFR 50, Appendix G and the calculation methods described in Westinghouse Report GTSD-A-1. 12, "Procedure for Developing Heatup and Cooldown Curves."

TURKEY POINT - UNITS 3 8a 4 Heatup and cooldown limit curves are calculated using the most limiting value of the nil-ductility reference temperature, RTNDT, at the end of 20 effective full power years (EFPY) of service life.

The 20 EFPY service life period is chosen such that the limiting RTNDT at the 1/4T location in 4ka ver~i' of 4-ke. AS~W E'@+ S<~~~~~

The selection of such a limiting RTNDT assures that all components in the Reactor Coolant System will be operated conservatively in accordance with applicable Code requirements. The heatup and cooldown limit curves, Figures 3.4-2, 3.4-3 and 3.4-4 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'redicted adjusted reference temperature at the end of the applicable service period (20 EFPY). The reactor vessel materials have been tested to determine their initial RTNDT'he results of these tests are shown in Tables B 3/4.4-1 and B 3/4.4-2 ~ Reactor operation and resultant fast neutron (E greater than 1 MeV) irradiation can cause an increase in the RTNpT Therefore, an adjusted reference tempera

ture, based upon the fluence and chemistry factors of the material has been predicted using Regulatory Guide 1.99, Revision 2, dated May 1988, "Radiation Embrittlement of Reactor Vessel Materials."

The heatup and cooldown limit curves of Figures 3.4-2, 3.4-3, and 3.4-4 include predicted adjustments for this shift in RTNDT at the end of the applicable service period. The actual shifts in RTNDT of the vessel materials will be established eriodicall during operation by removing and evaluating, in accordance with and 10 CFR Appendix H, reactor vessel material irradiation surve llance specimens installed near the insi e all o e react v ssel in e core area. P h p t 1 i p ansi e 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 materials (Intermediate to Lower Shell Circumferential Weld) in Units 3 and 4 are 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 kka ver si'e~ f kke p g<~ Et +s l~ C.FR S-~ P ppeM,'~ H TURKEY POINT - UNITS 3 Ec 4 B 3/4 4-9 AMENDMENT NOS.137 AND 132 P~& ~ ~ P ~ ~ ~r ~ 04 P e W -g r ~ yj +~ o r m s p e ~ e ~~ -r C rare z~)' +~i~g,~ '" t ,9c'tt~ ~ >'8 'lib 5 ~ <v r I faye sthaig 0 REACTOR COOLANT SYSTEM BASES PRESSURE/TEMPERATURE LIMITS (Continued) . Finally, the 10 CFR 50 Appendix G rule which addresses the metal temperature of the closure head flange and vessel flange regions is considered. The rule states that the minimum metal temperature for the flange regions should be at least 120 F higher than the limiting RTNDT for these regions when the pressure exceeds 20 percent of the preservice hydrostatic test pressure (621 psig). Since the limiting'TNDT for the flange regions for Turkey Point Units 3 and 4 is 44 F, the minimum temperature required for pressure of 621 psig and greater based on the Appendix G rul is 164 F. The heatup and cooldown curves as shown in Figures 3.4-2 to clearly satisfy the above requirement by ample margins. P.+-+ Finally, the composite curves for the heatup rate data and the cooldown rate data are adjusted for possible errors in the pressure and temperature sensing instruments by the values indicated on the respective curves. 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. OVERPRESSURE MITIGATING SYSTEM The Technical Specifications provide requirements to isolate High Pressure Safety Injection from the RCS and to prevent the start of an idle RCP if secondary temperature is more than 50 F above the RCS cold leg temperatures. These requirements are designed to ensure that mass and heat input transients more severe than those assumed in the low temperature overpressurization protection analysis cannot occur. The OPERABILITY of two PORVs or an RCS vent opening of at least 2.20 square inches ensures that the RCS will be protected from pressure transients which could exceed the limits of Appendix G to 10 CFR Part 50 when one or more of the RCS cold legs are less than or equal to 2754F. Either PORV has adequate relieving capability to protect the RCS 'from overpressurization when the transient is limited to either: (1) the star t of an idle RCP with the secondary water temperature of the steam generator less than or equal to 50'F above the RCS cold leg temperatures including margin for instrument error, or (2) the start of a HPSI pump and its injection into a water-solid RCS. When the PORVs or 2.2 square inch area vent is used to mitigate a plant transient, a special report is submitted. However, minor increases in pressure resulting from planned plant actions, which are relieved by designated openings in the

system, need not be reported.
