TS1184-0001A-LI01 Basis for Determination of No Significant Hazards Considerations We have reviewed the proposed change to allow a 15-minute time constraint for compliance with Technical Specification 3.l.3(c) in order to determine whether or not this change involves a significant hazards consideration.
Technical Specification 3.1.3 further requires that with the primary coolant temperature below 525°F, the reactor shall be subcritical by an amount equal to or greater than the potential reactivity insertion due to depressurization. Contrary to CE Standard Technical Specifications, however, the current Palisades Technical Specifications do not specify a time interval for compliance.
In our review, we have used the guidance of certain examples (48FR14870).
The above proposed change to the Palisades Technical Specifications provides a reasonable time interval for compliance with Technical Specification 3.l.3(c), and is consistent with CE Standard Technical Specifications. Additionally, the proposed change will preclude the necessity of immediately bringing the reactor subcritical by insertion of control rods, which may result in a further temperature decrease.
One of the examples (ii) in this guidance is if a change constitutes an additional limitation, restriction or control not presently included in the Technical Specification, then that change can be considered not likely to involve significant hazards considerations.
TS1184-0001A-LI01
Since this proposed change adds a 15-minute requirement to 3.l.3(c) which is more limiting than the generic LCO under 3.0.3which allows one (1) hour, we have determined that this change falls within the example and; therefore, the change does not involve a significant hazards consideration.
 
III. CONCLUSION The Palisades Plant Review Committee has reviewed this Technical Specification Change Request and has determined that this change does not involve an unreviewed safety question and therefore involves no significant hazards consideration.
