The air flow reduction may be indicative of a reduced air flow | | that would occur in the RB Emergency Cooling system if it was called upon to | | function in the event of a design basis accident. The design basis flow for | | the RB Emergency Cooling System is 25,000 CFM with the RB cooling fans in | | slow speed. Engineering judgement is that the current flow rate may be below | | 25,000 CFM if the system was called upon to function, hence the | | identification of a condition outside the plant design basis. | | | | "Engineering judgement is that: the Reactor Building Emergency Cooling | | System remains operable but may be degraded. The judgement that the system | | is operable with degraded air flow is based on the difference between | | conservative assumptions in environmental temperatures in the plant design | | basis analysis and current environmental conditions and in view of the fact | | that the environmental conditions within the Reactor Building in the design | | basis accident should enhance the current potential degraded system air | | flow. A formal internal justification of continued operation (JCO) will be | | prepared to document the basis for the engineering judgement and will be | | provided to the site NRC resident inspectors office. | | | | "Because GPU Nuclear has classified this condition as being potentially | | outside the design basis of the plant, GPU Nuclear is notifying the NRC | | Operations Center in accordance with 10 CFR 50.72(b)(1)(ii)(b).

OPERATIONS PERSONNEL DISCOVERED THAT REQUIREMENT #5 | | OF NUCLEAR CRITICALITY SAFETY ANALYSIS (NCSA) PLANT_003.A01 WAS NOT BEING | | MET. THE REQUIREMENT, MONITORING SURGE DRUM PRESSURE ONCE EACH SHIFT WAS | | BEING PERFORMED WITH THE INSTALLED PRESSURE INDICATOR WHICH WAS ISOLATED ON | | 5/20/99 TO ALLOW MAINTENANCE TO CALIBRATE. WHEN THE INDICATOR COULD NOT BE | | CALIBRATED IT WAS LEFT ISOLATED AND OPERATIONS WAS NOT MADE AWARE THAT OF | | THIS CONDITION. SINCE THE LINE WAS VALVED OFF THE DRUM PRESSURE WAS NOT | | MEASURED AS REQUIRED, THIS IS A LOSS OF A SINGLE CONTROL (CONCENTRATION) OF | | THE DOUBLE CONTINGENCY PROGRAM. THE SECOND CONTROL (MODERATION) WAS | | MAINTAINED THROUGHOUT THE EVENT. THE PRESSURE INDICATOR WAS VALVED IN AT | | 0905 HRS. ON 6/4/99. PREVIOUS MAINTENANCE IN THE CASCADE REGARDING SURGE | | DRUM CALIBRATION MAY HAVE RESULTED IN A SIMILAR SITUATION. | | | | "THE 'X' BANK SURGE DRUM WAS EVACUATED AND TAGGED OUT OF SERVICE FOR | | MAINTENANCE. | | THEREFORE, THE SURGE DRUM IS CONSIDERED EMPTY. ON 5/20/99 MAINTENANCE | | VALVED OFF THE DRUM TO DO WORK ON THE PRESSURE SENSOR. THE DRUM REMAINED | | VALVED OFF UNTIL 6/4/99. WHEN THE DRUM WAS VALVED BACK IN THE DRUM WAS | | STILL EVACUATED. THIS INDICATED THAT THE NCSA PRESSURE LIMIT WAS NEVER | | EXCEEDED (i.e., WET AIR IN-LEAKAGE DID NOT OCCUR), THEREFORE, THE SAFETY | | SIGNIFICANCE OF THIS EVENT IS LOW AND A CRITICALITY WAS NOT POSSIBLE. | | | | "FOR CRITICALITY TO OCCUR THE SURGE DRUM WOULD HAVE TO HAVE MATERIAL IN IT | | AND THE MATERIAL WOULD NAVE TO BE MODERATED BY WET AIR IN-LEAKAGE. THIS WAS | | EXPECTED TO OCCUR IN THIS CASE BECAUSE THE DRUM WAS HOLDING ITS PRESSURE | | BEFORE MAINTENANCE CALIBRATED THE PRESSURE SENSOR, AND THE FACT THAT OTHER | | SURGE DRUMS IN THE SAME ROOM WERE OPERATING AND THE ROOM TEMPERATURE WAS | | GREATER THAN 140�F. | | | | "THE ESTIMATED AMOUNT OF MATERIAL IN THE DRUM IS LESS THAN 600 gms. U-235 (A | | SAFE MASS AT 10% ENRICHMENT) DUE TO THE FACT THAT THE DRUM WAS EVACUATED | | PRIOR TO MAINTENANCE. WHEN THE PRESSURE SENSOR WAS VALVED BACK INTO THE | | DRUM, THE DRUM WAS STILL AT A VACUUM (NOTE: THE NCSA PRESSURE LIMIT ON THE | | DRUM IS 17 psia). THE MAXIMUM ENRICHMENT IN THIS DRUM IS 10%. THE FORM OF | | THE MATERIAL IS EITHER UF6 OR UO2F2. | | | | "THE MAINTENANCE PROCEDURE REQUIRES THE PRESSURE INDICATOR TO BE ISOLATED | | FOR CALIBRATION. THIS WAS DONE ON 5/20/99. WHEN THE SENSOR COULD NOT BE | | CALIBRATED, THE LINE WAS LEFT VALVED OFF AND OPERATIONS DID NOT KNOW THIS. | | THE NCSA REQUIRES THE PRESSURE ON THE DRUM TO BE MONITORED AND RECORDED EACH | | SHIFT, OPERATIONS WAS READING THE MT&E SENSOR INSTALLED.
