The | | condition required the Station to declare both zones inoperable, and placed | | Unit 1 in a 4 hour LCO to restore Secondary Containment. Unit 2 is already | | in Mode 5, however the condition would have prevented all additional fuel | | moves. The Standby Gas Treatment System was capable of maintaining the DP | | requirement of 0.25 " vac. water gauge during the test. By 0330 | | investigation had reduced flow from the two zones to approximately 2600 | | SCFM, and the LCO was exited. The inoperability of Secondary Containment is | | a loss of an entire Safety Function that is needed to control the release of | | radioactive material, and is reportable under 10CFR50.72(b)(3)(v)(c)." | | | | The licensee notified the NRC Resident Inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 39683 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: PALO VERDE REGION: 4 |NOTIFICATION DATE: 03/20/2003| | UNIT: [1] [2] [3] STATE: AZ |NOTIFICATION TIME: 13:13[EST]| | RXTYPE: [1] CE,[2] CE,[3] CE |EVENT DATE: 03/20/2003| +------------------------------------------------+EVENT TIME: 08:30[MST]| | NRC NOTIFIED BY: DAN MARKS |LAST UPDATE DATE: 03/20/2003| | HQ OPS OFFICER: ARLON COSTA +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |CLAUDE JOHNSON R4 | |10 CFR SECTION: | | |APRE 50.72(b)(2)(xi) OFFSITE NOTIFICATION | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 97 Power Operation |97 Power Operation | |2 N Y 98 Power Operation |98 Power Operation | |3 N Y 99 Power Operation |99 Power Operation | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | MEDIA COVERAGE OF TERRORIST TARGET | | | | "The following event description is based on information currently | | available.
