3.3.1.2 During power operation, the requirements of 3.3.1.1 may be modified to allow components to be inoperable at any one time.
More than one component may be in-operable at any one time provided that one train of the ECCS is operable.
If the requirements of 3.3.1.1 are not satisfied within the time period specified below, the reactor shall be placed in hot shutdown within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and at T

Any valve, interlock, or piping required for the functioning of one safety injection train and/or one low head safety injection train (RHR) may be inoperable provided repairs are completed within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Prior to initiating valve repairs, all valves in the system that provide the duplicate function shall be tested to demonstrate operability.
Power may be restored to any valve referenced in 3.3.1.1 g for the purposes of valve testing providing no more than one such valve has power restored and provided testing is completed and power removed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Attachment B
The proposed change will clarify existing Technical Specifica-tions and will provide for consistency between the Ginna Technical Specifications and the NRC Standard Technical Specifications (STS) for Westinghouse plants.
Specification 3.3.1.7, which addresses requirements in the event of ECCS subsystem inoperability, is to be revised to eliminate requirements not based on safety analyses and to address all portions of the ECCS including piping.
The requirement regarding number of inoperable components is restated to ensure that one train is always operable.
This restatement is necessary as a result of our implementing the definition of "operability" as described in our letter dated May 5, 1981.
The time period for corrective action is restated, consistent with the STS
~
The specified time period remains short such that the likelihood of requiring remaining operable equipment is small.
The requirement for reactor coolant drain tank (RCDT) pump operability in the event of a RHR pump inopera-bility has been deleted.
The RCDT pumps are not required to satisfy any safety analysis assumptions.
While they could provide added redundancy, they are substantially smaller than the RHR pumps so they cannot. provide a comparable level of decay heat removal.
Inoperability of piping and interlocks is added to the Specification for completeness and the Specifications are clarified to address only that portion of the RHR system required for the low head safety injection, including the recirculation phase.
The proposed changes do not substantially change the existing requirement, but do provide for clarity and completeness.
