4 1 1.0 Intmduction Dresden Nuclear Powcr Station is a three reactor generating facility owned and operated by the Commonwealth Edison Company of Chicago, Illinois. Dresden Station is located at the confluence of the Kankakee and Des Plaines Rivers, in Grundy County, near Morris, Illinois. Dresden Unit I is a General Electric Boiling Water Reactor with a design net electrical output rating of 200 megawatts electrical (MWe). The unit is retired in place with all nuclear fuel removed from the reactor vessel. Therefore, no Unit I operating data is provided in this report. Dresden Units 2 and 3 are General Electric Boiling Water Reactors with design net electrical output ratings of 794 MWe each. Waste heat is rejected to a man-made cooling lake using the Kankakce River for make-up and the Illinois River for blowdown. The Architect-Engineer for Dresden Units 2 and 3 was Sargent and Lundy of Chicago, Illinois This report for February,1993 was compiled by Gregory II. King of the Dresden Technical Staff, telephone nwnber (815) 942-2920, extension 2648. (GIIKLT92/2)/4

SUMMARY

l .i 02-01-93 to 02-26-93 Unit 3 entered the month on-line and operating at 760 MWe and operated steady state forL.~ j most of the month until the unit scrammed due to high reactor pressure at 1618 hours on 02-i 26-93. The root cause of the unit scram was due to the foreign material damaging the unit. turbine generator. The description of this event is described fully in LER number 93-007. l 02-26-93 to 02-28-93 Unit 3 finished the remainder of the month shutdown and in forced outage number 2 with a : system availability of 91.71 and a capacity factor of 84.38%. i f I t I i . i 1 i t e [ l I -f ] (GHKLT92/2)/6 -1

' Only those procedures that have required a new or an additional 10CFR j 50.59 review of changes are included. (Procedures approved for use during the month of January are. i summarized below) : i DIP 2400-03 Bypass of Unit 3 Drywell llich Radiation Monitor Group 2 Isolation Durine Refuel Outare : During Refuel. outages the Drywell Ifigh Radiation Monitor Group 2 Isolation is routinely jumpered out to prevent spurious ~ trips which frequently occur due to welding in the detector area. This procedure was written to eliminate the i necessity of using a Temporary Alteration and improve administrative controls. I DIP 2400-02 Hvoass of Unit 2 Drywell llich Radiation Monitor Group 2 Isolation durine Refuel Outane : During Refuel outages the Drywell High Radiation Monitor Group 2 Isolation is routinely jumpered out to prevent spurious - trips which frequently occur due to welding in the detector area. This procedure was written to eliminate the necessity of using a Temporary Alteration and improve administrative controls. l DES 8000-01 Reactor Protection M-G Set Output Breaker Trio Device : This is a new procedure to provide instructions to. f perform an inspection of the trip device in the RPS output breakers. This procedure supports LER 3-91-015.' Work was previously' done under an MMP and traveler.. This procedure provides for the placement of a' temporary feed to maintain power to the applicable refuel floor radiation moniton while perfonning the applicable Reactor Protection M-G set output breaker trip device test. The feed will be from a regular lighting l cabinet which will allow reactor building ventilation to run while the applicable RPS M-G set is out of service.

4 i 5.3 Significant tests and experiments not described in the MAR (Units 2 & 3) i Significant special procedures involving tests not described in the FSAR which were approved during the month of February,1993 are listed below: SP 92-12-147 Control Rod Drive Flow Control Valve Operability Test : This procedure will verify that the trim replacement of the 6A FCV has not affected the vahe's ability to operate. The SP will vary CRD System flow to verify newly installed valve trim in the 6A FCV can adequately throttle flow as required. SP 92-10-120 Secondary Containment 1 eak Rate Test for liardened Vent Afodification : blodification M12-2-90-029A requires that the 2-1601-24 valve be tested as a secondary contaimnent boundary as well as manual isolation damper 2-5772-104. This SP will test the 2-5772-104 manual isolation damper to ensure secondary containment can be maintaint4 with Drywell Vent / Purge inspection hatches open. SP 93-01-11 Work Activities Associated with the Removal and Reinstallation of the 2A Recire. Pumo durine D2R13 Ontare : This SP provides instructions for removing and reinstalling the 2A Reactor Recirculation Pump Motor from the Dry well and ensures that all conditions and requirements associated with the analysis of the heavy load movement, as etu!uated under exempt change D15176, are satisfied. SP 93-01-01 Modification M12-2-88-22C Testinz of Panels 902-54. 55. 56. 923-4. 5A and 7 : Commonwealth Edison committed to performing a detailed control room design review (DCRDR) per NUREG-0737, supplement 1. Modification M12-2-88-22I1 implements corrective action for this DCRDR. This SP is the Modification test for M12-2-88-22C. i l (GIIKLT92/2)/15 i
