TECHNICAL SPECIFICATION CHANGE REQUEST NO. 130 The Licensee requests that the attached revised pages replace the following pages of the existing Technical Specifications.
Replace 3-40c, 4-7a II.
REASON FOR CHANGE Current Technical Specifications do not address backup incore thermocouples.
This change request provides Tech Spec required operaoility and surveillance of the backup incore thermocouples display channel of four (4) thermocouples per core quadrant and a minimum of two (2) thermocouples per quadrant. This action is in response to Item (8) of NUREG 0737 II.F.2.
(See GPU Letter 82-007, dated February 2, 1982).
III.
SAFETY EVALUATION AND JUSTIFICATION OF CHANGE The proposed change increases reliability of the backup display channel by requiring a monthly check of that channels capability to display four incore thermocouples per core quadrant. New operability and surveillance requirements insure availability of the channel.
IV. 'NO SIGNIFICANT HAZARD CONSIDERATIONS The proposed change is administrative and adds surveillance and operability requirceents of the backup incore thermocouple display system beyond the scope of current Technical Specificatiom and, therefore, does not:
1.
involve a significant increase in the probability or consequences an accident previously evaluated; or 2.
create the possibility of a new or different kind of accident from any accident previously evaluated; or 3.
involve a significant reduction in a margin of safety.
V.
IMPLEMENTATION Implementation of this proposed amendment is requested to be effective 30 days after issuance.
VI.
AMENDMENT CLASSIFICATION (10 CFR 170.22)
This change request is administrative in nature and is, therefore, considered a Class II Amendment.
A check for $1,200.00 is enclosed.
