SUBJECT:
NOTICE OF ENFORCEMENT DISCRETION FOR COMMONWEAL TH EDISON COMPANY REGARDING THE DRESDEN NUCLEAR STATION, UNIT 3
Dear Mr. Lyster:
By letter dated February 22, 1994, yo*u requested the U.S. Nuclear Regulatory Commission (NRC) to exercise its discretion not *to enforce compliance with the required actions associated with the inability to perform Technical Specification Surveillance Requirement 4.7.B.2.b(3) within the allowable time frame.
Specifically, DIS 7500~01 "STANDBY GAS TREATMENT SYSTEM (SBGTS) AUTO-ACTUATION,"
which is required to be performed, at a minimum, every 18 months, will become.
overdue at 0817 hours0.00946 days <br />0.227 hours <br />0.00135 weeks <br />3.108685e-4 months <br /> on February 26, 1994. This date was calculated using the extension to the surveillance interval allowed by Technical Specification 1.0.CC based on the surveillance being last performed on Unit 3 at 0817 hours0.00946 days <br />0.227 hours <br />0.00135 weeks <br />3.108685e-4 months <br /> on April 10, 1992. Failure to perform Surveillance Requirement 4.7.B.2.b(3) within the specified time interval would require Unit 3 to be placed in a condition in which* the SBGTS would not be required within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> to comply with the Limiting Condition for Operation (LCO) action statement 3~7.B.l.b. Your staff provided as justification for continued operation that ~ll auto-actuation input signals
. to the SBGTS have been demonstrated operable as required by routine surveillance activities; the Unit 3 SBGTS responded as required to the Group II isolation auto-initiation signal involving the loss of instrument air on January 16, 1993; and the three previous performances of DIS 7500-1 were successful.
In addition, you identified and will take compensatory measures including minimizing switchyard operations that may increase the probability of a Loss of Offsite Pow~r and evolutions that may effect.SBGT operability must get prior approval from the Operating Engineer.
Based on our review of your justification* for continued operation including.
compensatory measures identified above, we have concluded that plant safety will
. not be unduly compromised and we are satisfied that such action is in the interest of the public health and safety. Therefore, this letter documents our intention to exercise.discretion not to enforce compliance with TS 4.7.B.2.b(3) 9403080070 940224 PDR ADOCK 05000249 p
