The steam generator tube | | rupture was initially estimated to be approximately 90 gallons per minute. | | At 1929, the reactor was manually tripped, and all rods fully inserted into | | the core. The faulted steam generator was isolated. Currently, reactor | | coolant system pressure is 2243 psig, temperature is 547 �F and pressurizer | | level is being maintained at 35%. The licensee declared an Alert | | classification at 1929 per EAL 3.1.2 (large amount of water out of the | | reactor coolant system). The NRC entered Standby at 2049 EST. | | | | The NRC response was deescalated to Monitoring at 2335 EST. | | | | The NRC Resident Inspector was notified of this event by the licensee. | | | | * * * UPDATE AT 1000 @2/16/00 * * * COMMISSIONER'S ASSISTANTS BRIEFING GIVEN | | BY RANDY BLOUGH ON THE INDIAN PT 2 ALERT. | | | | The following persons participated in the briefing: Region 1 RA (Hub | | Miller), R1 PAO(Diane Screnci), R1 (Jennifer England), RI (Pete | | Habighorst), R1DO (F.

Leakage from systems that are isolated from the | | recirculation flow path or that can be isolated from it, without degrading | | the ability to recirculate the reactor coolant system are not included in | | leakage requirement of the USFAR. | | R1DO (F.

The | | subject flaw was identified by Non-Destructive Examination (NDE) at the | | connection of Level Instrumentation to the RCS Hot Leg Piping. | | | | "Unit 1 was taken offline at 0010 on 2/5/2000 for scheduled maintenance. | | Boron buildup was identified on 2/15/00 at the subject connection while the | | plant was at cold shutdown condition. The accumulated boron indicates the | | leakage through the weld flaw is classified as very small weepage. The | | unidentified RCS leakrate prior to thc scheduled outage was 0.093 GPM. No | | unexplainable changes in RCS leakrate exist for cycle 16 operation. Due to | | the physical location of the connection, major scaffolding was required to | | access the area. At 2058 on 2/15/2000, NDE was complete identifying the | | reportable condition.

The leak is estimated to be 0.03 gpm based on | | historical trending of the reactor building normal sump. The leak was | | discovered during a reactor building entry to investigate reactor coolant | | pump seal indications. | | | | At 1352 EST on 02/16/00 shutdown was commenced. Unit 1 must be in Mode 3 | | (Hot Standby) by 02/17/00 at 0105 EST and in Mode 5 (Cold Shutdown) by | | 02/18/00 at 0105 EST per Technical Specification 3.4.13, "Reactor Coolant | | Operational Leakage." | | | | The post accident sampling line connects to the coolant cold leg piping | | between the "B" once through steam generator and the suction side of reactor | | coolant pump "1B2". The leak is coming from the area of a 90 degree elbow | | where the sampling line passes near the containment floor. | | | | All emergency core cooling systems and the Keowee system are fully operable. | | The electrical grid is also stable. | | | | The NRC Resident Inspector was notified of this event by the licensee. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Hospital |Event Number: 36699 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: ONCOLOGY INST.

The | | licensee uses a Nulceatron Micro Selection HDR #31024, controlled by an IBM | | G50 computer. It was discovered that after the dwell time was entered into | | the computer, if the enter key is pushed twice instead of once, the distance | | that the source moves is increased by 100% without warning the operator that | | the distance had changed. (If the source is supposed move 4 centimeters and | | you push the enter key twice that source will move 8 centimeters). A patient | | received three unintended site radiation treatments to his bronchial tube | | before the problem was discovered. An NRC Region 3 Inspector was at the | | facility when this incident occurred. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 36700 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: POINT BEACH REGION: 3 |NOTIFICATION DATE: 02/16/2000| | UNIT: [1] [2] [] STATE: WI |NOTIFICATION TIME: 19:19[EST]| | RXTYPE: [1] W-2-LP,[2] W-2-LP |EVENT DATE: 02/16/2000| +------------------------------------------------+EVENT TIME: 17:55[CST]| | NRC NOTIFIED BY: J SELL |LAST UPDATE DATE: 02/16/2000| | HQ OPS OFFICER: JOHN MacKINNON +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |BRUCE JORGENSEN R3 | |10 CFR SECTION: | | |AOUT 50.72(b)(1)(ii)(B) OUTSIDE DESIGN BASIS | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | |2 N Y 100 Power Operation |100 Power Operation | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | TEMPORARY FIRE PENETRATION IN THE CABLE SPREADING ROOM WAS FOUND TO BE | | POTENTAILLY OUTSIDE THE PLANTS DESIGN BASIS. | | | | A condition was discovered which is potentially outside the plants design | | basis.
