| PART 21 REPORT INVOLVING REPLACEMENT SIEMENS ELECTRICAL BREAKER COMPONENTS |
| NOT MEETING DESIGN SPECIFICATIONS |
| |
| "On March 26, 2001, Carolina Power & Light Company (CP&L) determined the |
| following condition to be reportable in accordance with 10 CFR Part 21. |
| |
| "Description of Defect or Failure to Comply: |
| |
| "Siemens RLN/RLNF breaker cubicle Mechanism Operated Cells (MOC) were |
| supplied to the Harris Nuclear Plant (HNP) as replacements which do not |
| match design specifications. The parts procured were received with improper |
| push bar length and configuration. The length and configuration are critical |
| characteristics of this component. Improper length and configuration of the |
| push bar on the MOC can result in the MOC not actuating upon breaker closure |
| as per design. These parts were received commercial grade and dedicated |
| onsite by CP&L for use in safety-related applications. CP&L's inspection of |
| critical characteristics failed to identify that the component was not |
| manufactured in accordance with the approved design specifications. |
| Therefore, the defective MOCs were available in HNP stores for installation |
| in safety-related applications. |
| |
| "HNP has identified a potential application where, had the subject MOC been |
| installed, safety related functions designed to help mitigate the |
| consequences of design basis events could have been lost. |
| |
| "A more detailed 30 day report will be submitted to the NRC in accordance |
| with 10 CFR 21.21 by April 25, 2001." |

EVENT TEXT

| UNIT 1 EXPERIENCED A GENERATOR TRIP FOR REASONS UNKNOWN |
| |
| At 1853EST on 3/28/01, Unit 1 experienced a main generator trip, turbine |
| trip and reactor scram. The first out indication showed "power load |
| unbalance." There were no maintenance or surveillance activities ongoing at |
| the time. All control rods fully inserted. During the transient reactor |
| vessel water level decreased to a minimum of -31 (Div I) and -37 (Div II) |
| inches as shown on level recorders. Both HPCI and RCIC initiated but did |
| not inject due to level increasing above the -35 inches setpoint required |
| for the injection valves to open. The four low-low pressure setpoint (1120 |
| psig) SRVs, i.e., "A", "C", "G" and "F", opened and reseated controlling |
| reactor pressure. Subsequent to the investigation, it was determined that |
| the "B" SRV also momentarily lifted based on a review of computer edits and |
| an approximate 10 degree F increase on the temperature recorder. The |
| highest recorded pressure was 1125 psig. Group II isolations occurred as |
| expected including initiation of the Standby Gas Treatment System. All |
| isolations have been reset and the affected equipment restored to standby |
| status. |
| |
| Unit 1 is currently stable in hot shutdown with reactor pressure controlled |
| using bypass valves to the main condenser. Condensate feed is in service |
| supplying makeup with the reactor recirculation pumps at minimum speed. An |
| event review team is responding to the site to determine the root cause. |
| Three 230KV breakers, i.e., two generator output and one switchyard, opened |
| during the transient. Unit 1 will remain shutdown pending the results of |
| the investigation and completion of other scheduled maintenance. |
| |
| The licensee informed the NRC resident inspector and does not plan a press |
| release at this time. |
