3/4.4 MAIN C00UlNT SYSTEM BASES 3/4.4.1 MAIN COOLANT LOOPS The plant is designed to cperate with all main coolant loops in operation, and maintain DNBR above 1.30 during all nonnal operations and anticipated transients. 'dith one main coolant loop not in operation, THERMAL POWER is restricted to < 75 percent of RATED THERMAL POWER.
With four loops operating, a loss of flow or low SG water level in two loops will cause a reactor trip. A loss of flow or low SG water level in one loop will cause a reactor trip with three loops operating.
Adequate main coolant loops are required to provide sufficient heat removal capability for removing core decay heat. Single failure con-siderations require placing the Shutdown Cooling System into operation if the required main coolant loops are not OPERABLE. A steam generator is capable of removing core decay heat by natural or forced circulation provided the conditions specified in 4.4.1.1.2 are met.
The requirement to maintain the baron concentration of an isolated loop greater than or equal to the boron concentration of tne operating loops ensures that no reactivity additier. to the core could occur during startup of an isolated loop. Verification of the boron concentration in an isolated loop prior to opening the stop valves provides a reassurance of the adequacy of the boron concentration in the isolated loop. Startup of an isolated loop will inject cool water from the loop into the core.
The reactivity transient resulting from this cool water injection is minimized by delaying isolated loop startup until its temperature is within 30*F of the operating loops. Making the reactor subcritical l
prior to loop startup prevents any power spika which could result from this cool water induced reactivity transient.
3/4.4.2 and 3/4.4.3 SAFETY VALVES The pressurizer code safety valves operate to p*avant the Main Coolant System from being pressurized above its Safety Limi' of 2735 psig. Each safety valve is designed to relieve 92.000 lbs per hour of saturated steam at the valve set point. The relief capacity of a single safety valve is adequate to relieve any overpressure condition which could occur during sNtdown.
In the event that no safety valves are OPERABLE, an operating Shutdown Cooling System connected to the Main l
Coolant System provides overpressure relief capability and will prevent Main Coolant System overpressurization during shutdown.
(

' YANKEE-ROWE B 3/4 4-1 Amendment No. 49 i
-~
MAIN COOLANT SYSTEM BASES Uuring operation, all pressurizer code safety valves must be OPERABLE to prevent the Main Coolant System trom being pressurized above its safety limit of 2735 psig. The combined relief capacity of all of these valves is greater than the maximum surge rate resulting from a complete loss of load assuming no reactor trip until the first Reactor Protective System trip set point is reached (i.e., no credit is taken for a direct reactor trip on the loss of load) and also assuming no operation of the power operated relief valves or steam dump valves.
Demonstration of the safety valves' lift settings will occur only during shutdown and will be performed in accordance with the provisions of Section XI of the ASME Boiler and Pressure Code.
3/4.4.4 PRESSURIZER A steam bubble in the pressurizer ensures that the Hain Coolant System is not a hydraulically solid system and is capable of accom-modating pressure surges during operation. The steam bubble also protects the pressurizer code, safety valves and power operated relief valve against water relief. The power operated relief valve and steam bubble function to relieve Hain Coolant System pressure during all design transients up to and including the design step load decrease with steam dump. Operation of the power operated relief valve minimizes the undesirable opening of the spring-loaded pressurizer code safety valves.
YANKEE-ROWE B 3/4 4-2
MAIN COOLANT SYSTEM _
BASES Ouring heatup, the thermal gradients in the reactor vessel wall produce thermai stresses which vary from compressive at the inner wall to tensile at the outer wall. These thennal induced compressive stresses tend to alleviate the tensile stresses induced by the internal pressure.
Therefore, a pressure-temperature curve based on tteady state conditions (i.e., no thennal stresses) represents a lower bound of all similar curves for finite neatup rates when tne inner wall of the vessel is treated as the governing location.
The heatup analysis also covers the detennination of pressure-temperature liuitations for the case in which the outer wall of the vessel becomes the controlling location. The thermal gradients established during heatup produce tensile stresses at the outer wall of the vessel. These stresses are additive to the pressure induced tensile stresses which are already present. The thermal induced stresses at the outer wall of the vessel are tensile and are dependent on both the rate of heatup and the time along the neatup camp; therefore, a lower bound cur,e similar to that described for the heatup of the inner wall cannot be defined. Consequently, for the cases in which the outer wall of the vessel becomes the stress controll'ng location, each heatup rate of interest must be analyzed on an individual basis.
The heatup limit curves, Figures 3.4-2, and 3.4-4, are composite curves which were prepared by detennining the most conservative case, with either the inside or outside wall controlling, for any heatup rate up to 100*F per hour. The cooldown limit curves, tigures, 3.4-3, and 3.4-5, are composite curves which were prepared based upon the same type analysis. The heatup and cooldown curves were prepared based upon a 10'F.
These limitations are derived by using beginning of life RTthe rules contained NT_e+ction III of the ASME Code including Ap S
G. Protection Against Nonductile Failure, and the rules contained in 10CFR50, Appendix u, tracture Toughness Requirements.

CONTAINMENT SYSTEMS BASES 3/4.6.1.6 CONTAINMENT VESSEL STRUCTURAL INTEGRITY This limitation ensures that the structural integrity of the containment will be maintained comparable to the original design stan-dards for the life of the facility. Structural integrity is required to ensure that the containment will withstand the maximum pressure of 31.6 psig in the event of a LOCA. A visual inspection in conjunction with Type A leakage tests is sufficient to demonstrate this capability.
3/4.6.1.7 CONTINUOUS LEAX MONITORING SYSTEM The OPERABILITY of the continuous leak monitoring system provides some assurance that the containment equipment hatch seal, emergency hatch seal, and airlock seal are not leaking excessively between Type A leak tests.
3/4.6.2 CONTAINMENT ISOLATION VALVES The OPERABILITY of the containment isolation valves ensures that the containment atmosphere will be isolated from the outside environment in the event of pressurization of the containment. Containment isolation l
within the time limits specified ensures that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses for a LOCA.
3/4.6.3 COMBUSTIBLE GAS CONTROL The OPERABILITY of the equipment and systems required for the detection and control of. hydrogen, gas ensures that this equipment will be available to maintain ~the hydrogen concentration within containment below its flammable limit during post-LOCA. conditions. The purge system is capable of controlling the expected hydrogen generation associated with 1) zirconium-water reactions, 2) radiolytic decomposition of water and 3) corrosion of metals within containment.
The hydrogen recirculating system is provided to ensure adequate mixing of the containment atmosphere following a LOCA. This mixing action will prevent localized accumulations of hydrogen from exceeding the flammable limit.
