Containment Vent Isolation Instrumentation B 3.3.6 B 3.3 INSTRUMENTATION B 3.3.6 Containment Vent Isolation Instrumentaticn -Th BASES BACKGROUND Containment Vent Isolation Instrumentation containment isolation valves in closes the the Containment Purge System. This action isolates the containment from the environment to minimize atmosphere releases of radioactivity in the event of an accident. The Reactor Building Purge System may be in use during reactor operation and with the reactor shutdown.

Containment vent isolation is initiated injection (SI) signal or by manual by a safety actuation. The Bases for LCO 3.3.2, "Engineered Safety Feature Actuation System (ESFAS) Instrumentation," discuss initiation of SI signals.

Redundant and independent gaseous radioactivity monitors measure the radioactivity lev'els of exhaust, each of which will initiate the containment purge its associated train of automatic Containment Vent Isolation upon detection of high gaseous radioactivity.

The Reactor Building Purge System has inner and outer containment isolation valves in its supply and exhaust J ducts. This system is described in the Bases for LCO 3.6.3, "Containment Isolation Valves."

APPLICABLE The containment isolation valves for SAFETY ANALYSES Purge System close within six seconds the Reactor Building following the DBA.

The containment vent isolation radiation backup to the SI signal to ensure monitors act as system supply and exhaust valves. closing of the purge air They are also the primary means for automatically isolating containment in the event of a fuel handling accident during shutdown. Containment isolation in turn ensures meeting the containment leakage rate assumptions of the safety analyses, the calculated accidental offsite and ensures that radiological doses are below 10 CFR 100 (Ref. 1) limits.

The Containment Vent Isolation instrumentation satisfies Criterion 3 of the NRC Policy Statement.

Containment Penetrations B 3.9.4 BAS ES BACKGROUND The Reactor Building Purge Ventilation System operates to (continued) supply outside air into the containment for ventilation cooling or heating, to equalize internal and external and pressures, and to reduce the concentration of noble gases within containment prior to and during personnel access. The supply and exhaust lines each contain two isolation valves.

Because of their large size, the 24-inch containment lower compartment purge valves are physically restricted to : 50 degrees open.

The Reactor Building Purge and Ventilation System valves opened in MODES 5 and 6, but are closed automatically can be by the Engineered Safety Features Actuation System (ESFAS).

In MODE 6, large air exchanges are necessary to conduct refueling operations. The normal 24-inch purge system is used for this purpose. The ventilation system must be either isolated or capable of being automatically isolated upon detection of high radiation levels within containment.

The other containment penetrations that provide direct from containment atmosphere to outside atmosphere must access isolated on at least one side. be Isolation may be achieved by an OPERABLE automatic isolation valve, or by a manual isolation valve, blind flange, or equivalent. Equivalent isolation methods must be approved and may include use of a material can provide a temporary, atmospheric pressure, ventilation that barrier for the other containment penetrations during movements (Ref. 1). fuel Closure by other valves or blind flanges may be used if they are similar in capability to those for containment isolation. provided These may be constructed of standard materials and may be justified on the basis of either analysis methods or reasonable engineering judgment normal (Ref. 4).

APPLICABLE During CORE ALTERATIONS or movement of irradiated fuel SAFETY ANALYSES assemblies within containment, the most severe radiological consequences result from a fuel handling accident.

The fuel handling accident is a postulated event that involves irradiated fuel (Ref. 2). damage to Fuel handling accidents, analyzed in Reference 3, include dropping a single irradiated fuel and handling tool or a heavy object onto other irradiated assembly assemblies. fuel The requirements of LCO 3.9.7, "Refueling Cavity Water Level," in conjunction with a minimum decay time of 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to irradiated fuel movement with containment closure capability ensures that the release of fission radioactivity, subsequent to a fuel handling accident, product in doses that are well within the guideline values specifiedresults 10 CFR 100. in Standard Review Plan, Section 15.7.4, Rev. 1 (Ref. 3), defines "well within" 10 CFR 100 to be 25%

the 10 CFR 100 values. or less of The acceptance limits for offsite radiation exposure will be 25% of 10 CFR 100 values or the NRC staff approved licensing basis (e.g., a specified fraction of 10 CFR 100 limits).

Containment penetrations satisfy Criterion 3 of the NRC Policy Statement.

Turbine Overspeed Protection B 3.3.5 BASES ACTIONS B.1 (continued) taking into account the redundant capabilities afforded by the OPERABLE valve in the same steam line(s) and reasonable time for repairs.

B.2 A first alternative to Required Action B.1 is to close at least one valve in the affected steam line(s). This places the low pressure steam line(s) with the inoperable valve(s) in a no flow condition. This ensures total steam isolation to the low pressure turbine(s) in the event of an overspeed condition, even with a single failure of another reheat stop valve or reheat intercept valve. An additional 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (total of 78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br />) are allowed for a power reduction, if necessary, in an orderly manner and without challenging plant systems.

B.3 A second alternative is to isolate the turbine from the steam supply. This places the turbine in a condition where overspeed protection is not required. Again, an additional 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (total of 78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br />) are allowed for a power reduction, if necessary, in an orderly manner and without challenging plant systems.

C.1 If the Turbine Overspeed Protection System is inoperable for causes other than Condition A or Condition B, the turbine must be placed in a condition where overspeed protection is not required. This is accomplished by isolating the turbine from the steam supply system. A Completion Time of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> is allowed to shutdown the turbine in an orderly manner and without challenging plant systems.

Isolation Devices B 3.8.1 BASES TECHNICAL SURVEILLANCE TSR 3.8.1.3 2)

REQUIREMENTS This surveillance requires that the performance of a CHANNEL (continued) CALIBRATION of all protective relays associated with medium voltage (6.9 kV) isolation overcurrent devices. A CHANNEL CALIBRATION assures that the relays will be able to detect overcurrent conditions on the non-Class 1E loads. The Frequency of 18 months is consistent with the typical industry refueling cycle.

TSR 3.8.1.4 This surveillance requires the performance of an integrated system functional test which verifies that the relays and associated medium voltage (6.9 kV) circuit breakers function as designed to isolate fault currents. An integrated test assures that the individual elements of the protection scheme, the relays, breakers and other control circuits, interact as designed.

The surveillance has been modified by a Note stating that if a failure is discovered in the integrated functional test, an additional representative sample of at least 10% of all the circuit breakers of the inoperable type shall also be tested to assure that there is no common cause failure mechanism that could systematically affect all breakers of a given type.

The Frequency of 18 months coincides with the typical industry refueling cycle.

TSR 3.8.1.5 This surveillance requires the inspection of each circuit breaker and the performance of procedures prepared in conjunction with the manufacturer's recommendations. By performance of recommended maintenance, the likelihood for the circuit breakers to become inoperable can be minimized.

The 72 months periodicity for Class 1E circuit breaker, (Ref. 5), takes into consideration the low frequency of operation of the circuit breakers and the low likelihood that operation and maintenance activities at the plant could adversely affect the OPERABILITY of the circuit breaker.

Containment Penetration Condgctor Overcurrent Protection Devices B 3.8.2 BASES TECHNICAL TSR 3.8.2.4 SURVEILLANCE REQUIREMENTS This surveillance requires the performance of a functional (continued) test on a representative sample of ; 10% of each type electrically-operated circuit breaker used as penetration of protection. This sample size is sufficiently large to represent the actual failure distribution within the whole population of circuit breakers of a given type used in the plant. If there are any failure mechanisms that could affect the OPERABILITY of the circuit breaker(s),

they are likely to have occurred in the sample tested. The 18 month Frequency takes into consideration the infrequent operation of the breakers and their correspondingly low failure rate.

The Surveillance is augmented by three Notes. The first Note states that the breakers shall be selected for testing on a rotating basis. This ensures that all of the breakers will eventually be tested and those failures that may not have been discovered in the initial 10% samples will eventually be discovered. The second Note describes the functional test procedure and the response to be verified to ensure OPERABILITY.

The third Note states that for each electrically-operated circuit breaker found inoperable during functional tests an additional representative sample of 10% of the defective type shall be functionally tested until no more failures are found or all of that type have been functionally tested. This helps to ensure that a failure discovered in the representative sample was not caused by a failure mechanism that could systematically affect other breakers in the overall population of breakers of the same type.

TSR 3.8.2.5 This surveillance requires the inspection of each circuit breaker and the performance of preventive maintenance in accordance with procedures prepared in conjunction with the manufacturers recommendation. Performance of recommended preventive maintenance helps ensure the operability of the circuit breakers. The 72 months periodicity for Class 1E and 96 months for non-Class 1E circuit breakers, (Ref. 4), takes into consideration known failure rates for the circuit breakers and operating experience.

Refueling Machine B 3.9.3 B 3.9 REFUELING'OPERATIONS B 3.9.3 Refueling Machine BASES R

BACKGROUND The refueling machine is used during CORE ALTERATIONS to either move fuel assemblies to new'positions in the core, load new fuel assemblies, or unload spent fuel assemblies.

The refueling machine consists of a rectilinear bridge and trolley crane with a vertical mast extending down into the refueling water. The bridge and trolley motions position the vertical mast over are used to a fuel assembly in the core.

A long tube with a pneumatic gripper on the end is lowered down out of the mast to grip the fuel assembly and manipulate it so that it can be transported to its new position.

The refueling machine has two auxiliary monorail which are located on each side hoists of the bridge. The auxiliary hoists are used for the movement of control rod drive shafts in order to facilitate the refueling the hoist, the drive shafts must process. Before using be disconnected from their respective control rods and, with the upper internals, removed from the vessel (Ref.

TECHNICAL TSR 3.9.3.1 SURVEILLANCE REQUIREMENTS TSR 3.9.3.1 requires the performance of three tests on the refueling machine. A 1oad test of 3150 pounds must be performed on the refueling machine to verify its capacity.

A test must be performed to demonstrate an automatic electrical load cutoff before the crane load .

is greater than 2650 pounds. A test must also be performed to demonstrate second automatic electrical load cutoff before a the crane load is greater than 2800 pounds. These tests verify that the capacity and the load limits are still within the Technical Requirements. The Surveillance Frequency of 18 months is based upon engineering judgement, manufacturer recommendation, the fact that the refueling machine is an infrequently used and highly reliable piece of equipment, and consistency with the typical industry refueling cycle.
