{{#Wiki_filter:PROPOSED CHANGE LIMITING CONDITIONS FOR OPERATION (GENERAL) TECHNICAL SPECIFICATIONS SALEM UNITS 1 AND 2 Description *of Change Clarification of the present technical specifications in regard to the use of the term "operable" as it applies to the single failure criterion for safety systems. Rea*son *for* Change To assure that no set of equipment outages would be aJ.,lowed to persist that would result in the facility being in an unprotected condition. Safety Evaluation This change only involves cJ.,arification to the curretit technical specification and therefore,.does not constitute an unreviewed safety question.

3/4.0 APPLICABILITY BASES The specifications of this section provide the general requirements applicable to each of the Limiting Conditions for Operation and Surveillance Requirements within Section 3/4. 3.0. 1 This specification defines the applicability of each specification in terms of defined OPERATIONAL MODES or other specified conditions and is provided to delineate specifically when each specification is applicable. 3.0.2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.

Exceptions to* this provision have been provided for a limited number of specifications when startup with inoperable equipment would not affect plant safety. These exceptions are stated in the ACTION statements of the appropriate specifications. / I S ""-. ;f.L.,,, < /, c.....!/ SALEM - UNIT 2 B 3/c;. 0-1
Revised se*ction 3. 0. 3 3.0.3 In the event a Limiting Condition for Operation and/or as-sociated ACTION requirements cannot be satisfied because of cir-cumstances in excess of those addressed in the specification, the unit shall be placed in at least HOT STANDBY within 1 hour, in at least HOT SHUTDOWN within the next 6 hours, and in at least COLD SHUTDOWN within the following 30 hours unless corrective measures are completed that permit operation under the permissible ACTION statements for the specified time interval as measured from initial discovery or until the reactor is placed in a MODE in which the specification is not applicable. Exceptions to these requirements shall be stated in the individual specification. New Section: 3. o*. 5 3.0.5 When a system, subsystem, train, component or device is determined to be inoperable solely because its emergency power source is inoperable, or solely because its normal power source is inoperable, it may be considered OPERABLE for, the purpose of satisfying the requirements of its applicable Limiting Condition for Operation, provided: (1) its corresponding normal or emer-gency power source is OPERABLE: and (2) all of its redundant system(s), subsystem(s), train(s), component(s) and device(s) are OPERABLE, or likewise satisfy the requirements of this specifi-cation. Unless both conditions (1) and (2) are satisfied, the unit shall be placed in at least HOT STANDBY within 1 hour, in at least HOT SHUTDOWN within the next 6 hours, and in at least COLD SEUTDOWN within the following 30 hours. This specification is not applicable in MODES 5 or 6. 3.0.3 This specification delineates the ACTION to be taken for circumstances not directly provided, for in the,ACTION statements and whose occurrence would violate the intent of the specifi-cation. For example, Specification 3.5.1 requ,ires each Reactor Coolant System accumulator to be OPERABLE and provides explicit ACTlON requirements if one accumulator is inoperable. Under the terms of Specification 3.0.3, if more than one accumulator is inoperable, the unit is required to be in at least HOT STANDBY within 1 hour and in at least HOT SHUTDOWN within the following 6 hours. As a further example, Specification 3.6.2.l requires two Containment Spray Systems to be OPEMBLE and provides explicit ACTION requirements if one spray system is inoperable: Under the terms of Specification 3.0.3, if both of the required Containment Spray Systems are inoperable, the unit is required to be in at least HOT STANDBY within 1 hour, in at least HOT SHUTDOWN within the following 6 hours and in at least COLD SHUTDOWN in the next 30 hours. It is assumed that the unit is brought to the required MODE within the required times by promptly initiating and carry-ing out the appropriate ACTION statement.
2 - New Bases 'S"e*ctiot1 :3.*o.5 3.0.5.This specification delineates what additional conditions must be satisfied to permit operation to continue, consistent with the ACTION statements for power sources, when a normal or emergency power. source is not OPERABLE.. It specifically pro-hibits operation when one division is inoperable because its normal or emergency power source is inoperable and a system, subsystem, train, component or device in. another division is inoperable for another reason.
- The provisions of this specification permit the ACTJ;ON statements*
associated with individual systems, subsystems, traJ.ns, compo-nents, or devices to be consistent with the ACTION statements of the associated electrical power source. It allows operation to be governed by the time limits of the ACTION statement associated
- with the Limiting Condition for Operation for the normal or emergency power source, not the individual ACTION statements for each system, subsystem, train, component Or;' device that is de-termined to be inoperable solely beca.use of -th,e. inoperabili ty of its normal or emergency power source.
For example,* Specification 3. 8. l.*l requires in; part that three emergency dies.el. generators be OPERABLE. The ACTION statement provides for a 72 hour out-of-service time when.one emergency diesel generator is not OPERABLE. If the definition of OPERABLE were applied withciut consideration of Spedification 3~0.5, all systems, subsysterris,*trains, components and devices supplied by the inoperable emergency power source would also be inoperable. This would dictate invoking*the applicable ACT;I:ON statements for each of the applicable Limiting Conditions for Operation. How-ever, the *provisions of Specification 3.0.5 permit the time limits for continued operation to be consistent with the ACTION
- .Statement for the inoperable emergency diesel generator instead I provided the other specified conditicins are satisfied.
In this case,* this would mean that the corresponding normal power source must be *oPERA.BLE, and all redundant systerris, su.bsysterris, trains, components, and devices* must be OPEMBLE, or otherwise *sati'sfy Specification 3. O. 5 (i. e,.be *capable of performing their design function and ha;ve at least one *normal or one emergency power
- source OPERABLE).
If they are not satisfied,.shutdown is re-quired in accordance ~ith this specification. As a further example, Specification 3.8.1.1 reg;ui:r;"es ;in part that two physically independent circuits between the offsite trans-mission network. and* the* onsi te. Class IE distribution system be OPERABLE. The ACTION statement provides a 24 hciur out~of-service time *when both. required offsite *circuits are not Ol?ERA,BLE. If the definition of.OPERABLE were applied without consideration of Specification 3.0.5, *all systems, subsystems, trains, components and devices* supplied by the inoperable no:r*mal power sources, both of the offsite 'circuits, would also be inoperable. Th.is would
- dictate invoking the applicable ACTION statements for each of the applicable LCOs.
However, the provisions of Specification 3.0.5 permit the time limits for continued operation to be consistent with the ACTION statement for the inoperable normal power sources instead, provided the other specified conditions are satisfied. In this case, this would mean that for one division the emergency power source must be OPERABLE (as must be the components supplied by the emerge.ncy power source) and all redundant systems, sub-systems, trains, components and devices in the other division must be OPERABLE, or likewise satisfy Specification 3.0.5 (i.e., be capable of performing their design functions and have an emergency power source OPERABLE). In other words, all three emergency power sources must be OPERABLE and all redundant sys-tems, subsystems, trains, components and devices in all three divisions must also be OPERABLE. If these conditi0ns are not satisfied, shutdown. is required in accordance with this specification. In MODES 5 or 6 Specification 3.0.5 is not applicable, and thus the individual ACTION statements for each applicable Limiting Condition for Operation in these MODES must be adhered to.}}
