There were no adverse | | safety consequences or implications as a result of this event. The event | | did not adversely affect the safe operation of the plant or health and | | safety of the public. An investigation is in progress to determine the | | cause of the event. | | | | "Engineering personnel are preparing a change to the piping support design | | with expected completion within the Technical Specification allowed | | Completion Time of 72 hours. | | | | "This condition does not apply to the other train of Unit 2 or Palo Verde | | Units 1 or 3." | | | | The licensee informed the NRC Resident Inspector of this notification. | | | | * * * UPDATE AT 1635 ON 3/19/99 BY HAZELWOOD, TAKEN BY WEAVER * * * | | The licensee desires to retract this event. The design intent of the | | support is to restrain pipe motion in the vertical direction only. The | | support is not intended to restrain pipe motion in the axial direction. | | Subsequent re-inspection of the subject pipe support determined the | | existence of a gap beneath the bottom end plate. Given the existence of | | this gap, the pipe support will function as originally intended. | | Accordingly, there would be no overload condition and the pipe support is | | acceptable and in accordance with design. Following racking in the pump | | breaker and performing a functional run, Operations declared the Train B | | Containment Spray System operable. | | | | The licensee informed the NRC resident inspector. The HOO notified the R4DO | | (Harrell). | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 35488 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: SUSQUEHANNA REGION: 1 |NOTIFICATION DATE: 03/19/1999| | UNIT: [] [2] [] STATE: PA |NOTIFICATION TIME: 11:51[EST]| | RXTYPE: [1] GE-4,[2] GE-4 |EVENT DATE: 03/19/1999| +------------------------------------------------+EVENT TIME: 10:00[EST]| | NRC NOTIFIED BY: ROBERT M.

The | | overall Total Combined Maximum Pathway Leakage can not to be determined | | based on the inability to pressurize the 'C' Outboard and 'D' Inboard Main | | Steam Isolation Valves. The 'as found' Minimum Combined Pathway Leakage is | | 255 scfh, which is below the 300 scfh used in the Offsite Dose Analysis.

Fuel movement was | | halted until the equipment hatch bolts were re-tightened and the inleakage | | was terminated. The inleakage was caused by a pressure differential across | | the equipment hatch set up by the containment ventilation. The design basis | | fuel handling accident for BVPS Unit No. 2 assumes that there is no pressure | | differential across the containment equipment hatch since the containment | | ventilation would be automatically secured upon a high radiation signal. It | | was originally believed that the door would have been able to contain any | | air transfer without the pressure differential across the door since it was | | closed with ten bolts in place versus the four required by Technical | | Specification 19.4 during fuel movement. | | | | "Information was obtained on March 19, 1999 that 1) the containment | | equipment hatch may have become ajar due to inadequate support during an | | equipment hatch chain hoist preventative maintenance and 2) there was a | | sufficient separation between the containment wall and the equipment hatch | | door to allow some light to be seen on the inside of containment coming from | | the outside. Given this information, it could not be concluded that the | | containment capability of the equipment hatch would have been sufficient to | | have performed its safety function during a fuel handling accident if it | | were postulated to occur. Since the BVPS Unit No. 2 design basis fuel | | handling accident inside containment concludes that environmental release is | | precluded, this condition violated the UFSAR safety analysis. Therefore this | | indication of an air gap through the closed containment equipment hatch is | | being reported as a condition that alone could have prevented the | | fulfillment of the safety function of structures or systems that are needed | | to control the release of radioactive material pursuant to 10 CFR | | 50.72(b)(2)(iii)(C)." | | | | The licensee notified the NRC resident inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 35491 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: INDIAN POINT REGION: 1 |NOTIFICATION DATE: 03/19/1999| | UNIT: [] [3] [] STATE: NY |NOTIFICATION TIME: 14:50[EST]| | RXTYPE: [2] W-4-LP,[3] W-4-LP |EVENT DATE: 03/19/1999| +------------------------------------------------+EVENT TIME: 14:10[EST]| | NRC NOTIFIED BY: TOM MCKEE |LAST UPDATE DATE: 03/19/1999| | HQ OPS OFFICER: DOUG WEAVER +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |JACK MCFADDEN R1 | |10 CFR SECTION: | | |APRE 50.72(b)(2)(vi) OFFSITE NOTIFICATION | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ | | | |3 N Y 100 Power Operation |100 Power Operation | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | OFFSITE NOTIFICATION - FREON RELEASE | | | | The licensee notified the New York Department of Environmental Conservation | | of a freon leak.
