I.

INTRODUCTION A design weakness was found to exist in the LPCI (RHR) swing bus transfer schemes for Dresden Units 2 & 3 and Quad Cities Units 1 & 2.

The design was such that the loss of 125 Vdc Division II control power would prevent an automatic transfer from taking place. This would result in all four LPCI (RHR) pumps being unable to inject water into the reactor vessel when required.

A design modification has since been issued for each unit which causes the circuitry to respond correctly to the loss of a de power source.

Based.upon the above identified.design inadequacy, CECo authorized an indepth comprehensive review of each de system for Quad Cities Unit 1. A design review was performed and the results were presented in a report dated June 8, 1988. This report was issued to CECo on June 9, 1988, under S&L Letter No. Q327E.

II.

. PURPOSE The purpose of this study is to review the Oresden Units 2 & 3 and Quad Cities Unit 2 de power system and ascertain whether or not any other single de failu~e exists at these units whi~h could adversely impact the availability of the*Emergency Core Cooling System (ECCS).

III.

REVIEW APPROACH

The ECCS equipment at the subject units and their de bus assignments along with the operationa 1 r.equirements wi 11 be compared to the results obtained from the Quad Cities Unit 1 review.

Any equipment or system considered to be unique or dissimilar from those already analyzed for Quad Cities Unit 1 will be reviewed in depth.

1

l:

This study will address the 125 Vdc, 250 Vdc and 48 Vdc power systems.

(Appendix C of this study report contains key diagrams of each station's 125 Vdc and 250 Vdc buses.)

IV.

ECCS SUBSYSTEM DIFFERENCES The Low Pressure Coolant Injection/Containment Cooling Subsystem at Dresden Units 2 & 3 fulfills the same objectives as the Low Pressure Coolant Injection mode and the Containment Cooling Mode of the Residual Heat Removal System at Quad Cities Units 1 & 2.

V.

REVIEW RESULTS A.

125 Vdc System The emergency ac power system configuration for each unit is illustrated in Figures 1, 2, 3, *and 4 of Appendix A of this report. Also included in these figures is the de control power source assignment for each safety-related ECCS pump breaker and 6ther bus source and tie breakers. Table 1 in Appendix B of this report provides a comparison between the four units of the assignment of 125 Vdc control power to ECCS loads and certain auxiliary equipment loads.

From these figures and this table, it is evident that the assignments of ECCS loads to de sources of power are similar between units. The schematic and key diagrams listed in Section VII of this report were utilized to compare the operational requirements of ECCS equipment and the emergency auxiliary power system equipment between all four units.

No major differences were uncovered in our review.

The consequences of each 125 Vdc circuits failure on ECCS availability did not differ between the units. Thus the complete loss of any 125 Vdc source would result in the availability of "J~ke" equipment at each unit.

B.

250 Vdc System The only ECCS loads connected to the 250 Vdc system for each unit are those associated with the High Pressure Coolant Injection (HPCI) subsystem. Therefore, the equipment/systems available following the loss of a 250 Vdc source are the same as those*

presented in the Quad Cities Unit 1 Study Report.

C.

48/24 Vdc System The 48/24 Vdc systems at Quad Cities Units 1 & 2 do not feed* any ECCS equipment..The 48/24 Vdc systems at Dresden Un.its 2 & 3 are used to supply power to the analog trip system. Certain outputs from the analog trip system ar~ used in ECCS applications.

S&L has previously studied the effects of losing the ATS power supply (see S&L report #SL-4413 revised issue dated September 12, 1988).

The conclusion reached in report (SL-4413) is that the loss of 48/24 Vdc power supply does not degrade the safety function of the ECCS circuits below an acceptable level.

VI.

CONCLUSIONS Based on the Quad Cities Unit 1 comprehensive de study report.and this study by comparison, it is evident that the design of the Emergency Core Cooling System and supportive Auxiliary Power Systems are very*

~imi lar between the four un~ts. No other desi.gn deficiencies have been identified which could prevent the fulfillment of the design basis safety functions of the Emergency Core Cooling Systems at Dresden Units 2 & 3 and Quad Cities Units 1 & 2 following a single de supply failure.
