Event Notification Report for August 16, 2000

OFFSITE NOTIFICATION REGARDING A LARGE FISH KILL

The following text is a portion of a facsimile received from the licensee:

"[The] decision was made today (08/17/00) at 1130 [CDT] to notify offsite agencies concerning a large fish kill at Prairie Island. This [was the] result of the planned zebra mussel treatment that was taking place at the plant."

The licensee stated that the event occurred on 08/16/00 and that the fish kill involved approximately 7,500 young fish (mainly catfish and minnows approximately 2" to 5" in length). The majority of these fish were discovered in the plant's recycle canal. However, a few dead fish were also found in the Mississippi River.

The licensee notified both the state and Goodhue County. The licensee also plans to notify the NRC resident inspector. In addition, a press release may be issued because this may be a media sensitive event.

* * * UPDATE 1145EDT 8/21/00 FROM BILL MATHER TO S. SANDIN * * *

The licensee is correcting this report to read that 75,000 young fish were killed. The licensee informed the NRC resident inspector. Notified R3DO(Hiland).

UNIT 1 DECLARED HIGH PRESSURE COOLANT INJECTION (HPCI) INOPERABLE DUE TO A FAILURE DURING SURVEILLANCE TESTING

"While performing weekly exercise per Operating Order 00-01-0200S, High Pressure Coolant Injection turbine stop valve failed to close when trip solenoid pushbutton was depressed.

"High Pressure Coolant Injection was declared inoperable.

"Cause of turbine stop valve failure to close is under investigation."

With HPCI inoperable, Unit 1 entered a 14 day LCO Action Statement. Both Maintenance and Engineering are evaluating corrective actions. The licensee will inform the NRC Resident Inspector.

The North Carolina Division of Radiation Protection reported a radiography camera with a disconnected source.

The state discovered, while reviewing records, they had mis-filed an incident report from a licensee reporting a source had disconnected on a Source Production and Equipment Co. (SPEC) model #150 serial #316 radiography camera. This occurred when Quality NDE(currently Janx) was performing work in Roaring River, N.C. and while they were retrieving the source to its shielded position, the drive cable broke at the gearbox. The licensee followed emergency procedures and brought two more radiographers to the site and retrieved the source to the shielded position manually. Readings of 2mr/hr @ 6" were measured when the source was retracted to the shielded position. The source(#EH1804) at the time of the incident(01/18/99) measured 25 curies @ Iridium-192 and it was disposed 3/99. The individuals involved in the recovery of the source received an actual dose of <8 millirem. The licensee had filed this incident report on 02/09/99 with the State, which was within the required time.

N.C. incident report #00-33

A contract supervisor tested positive for alcohol during random testing. His access was immediately suspended. Review of his work determined that their was no impact on plant safety.

The NRC Resident Inspector was notified of this event by the licensee.

SMOKE SEEN COMING FROM "2C" SERVICE WATER PUMP MOTOR

"2C" Service Water Pump (swing) motor was seen having smoke coming from it. On site fire brigade was sent out to the Service Water building and extinguished the fire at 1609 CT. The licensee declared an Alert at 1625 CT due to the potential of the fire affecting ECCS equipment. No offsite assistance was needed and no other equipment onsite was damaged by the fire. Service Water Pumps "2A", "2B", "2D", & "2E" remain in service. All Emergency Core Cooling Systems are fully operable if needed.

Fire Alarm for Service Water pump was received in control room at 1548 CT. A person was immediately dispatched to investigate the alarm. Person reported back to control room at 1552 CT that smoke was coming from "2C" Service Water motor. Licensee entered AOP 29 (Plant Fire) at 1552 CT. At 1555 CT "2C" Service Water Pump tripped for unknown reason. Service Water pump flow was degraded for approximately 15 seconds at which time another Service Water pump was placed in service. Lowest service water pressure reached was 70 psi (min pressure is 60 psi). At 1609 CT report received that fire had been extinguished using carbon dioxide. 1616 CT AOP 29 was exited. The licensee notified state and local officials of entering Alert classification.

The NRC Resident Inspector was in the control room during the event.

NRC Operation Center was notified by Brad Grinstead of the Alabama Department of Public Health and by Kerri Seber of the Florida State Warning Point of the Farley Unit 2 Alert.

* * * UPDATE ON 08/16/00 AT 1845 ET BY G RHODES TAKEN BY MACKINNON * * *

Alert was terminated at 1736 CT due to fire being out and all systems operating properly.

"At 1625 [CT] FNP staff declared an Alert Emergency classification based on criteria found in site procedures. The 2C Service Water Pump motor had faulted resulting in a small fire in the Service Water Intake Structure. The Site Fire Brigade responded and the fire was extinguished promptly. No other equipment was damaged. The FNP Unit 2 Service Water system has 5 pumps and requires 2 pumps per train (4 pumps total) to ensure that system design functions are met. The 2C Service Water Pump is a swing pump that can be aligned to either train. The remaining four Unit 2 Service Water pumps are currently operable and in service.

"The FNP staff has assessed this event. No plant personnel were injured and only limited damage to plant equipment as described above occurred. There was no affect on the health and safety of the general public and no release of radiation. The Alert was terminated at 1736 [CT]. Both Units are continuing to operate at 100% power."

R2DO (Paul Fredrickson) & IRO (Congel) notified.

The NRC Resident Inspector was notified of this update by the licensee.

***** UPDATE/RETRACTION AT 1727 ON 08/18/00 FROM CHERI COLLINS TO LEIGH TROCINE *****

The licensee is retracting this event notification. The following text is a portion of a facsimile received from the licensee:

"Farley Nuclear Plant ENS Update - Retraction of Alert Emergency due to Fire at the Service Water Intake Structure"

"Farley Nuclear Plant [(FNP)] is retracting the Alert Emergency Declaration that occurred at 1625 CDT and was terminated at 1736 CDT on August 16, 2000. FNP Staff personnel made this declaration based on a conservative interpretation of the classification requirements in their internal site procedures. The site procedure requires an Alert Classification to be declared when a fire occurs that potentially affects Emergency Core Cooling Systems (ECCS). The Service Water System supplies cooling water to ECCS components, and therefore, when a 2C Service Water Pump motor fault occurred requiring site fire brigade response, FNP staff felt that the most appropriate and conservative approach was to declare the Alert Classification."

"Subsequently, [the] FNP Staff determined that while there was a fire internal to the motor casing of the 2C Service Water Pump, the ECCS was not affected since the required number of Service Water pumps remained available to support ECCS operation. Although a fire in a vital area represents a potential safety hazard, this fire did not rise to the level of safety hazard warranting an Alert Emergency Classification. [The] FNP Staff now believes that no classification should have been declared, and we are retracting this event notification."

The licensee notified the Alabama Department of the Emergency Management, Georgia Emergency Management Agency, Florida Division of Emergency Management , and other appropriate local officials. The licensee has also notified the NRC resident inspector. In addition, the licensee plans to issue a press release on Monday (08/21/00).

The NRC operations officer notified the R2DO (Fredrickson), NRR EO (Beckner), IRO (Miller), and PAO (Beecher).

The following text is a portion of a facsimile received from the licensee:

"[This was a] 72-hr phone call for compliance with [procedure] AP-0005762, Rev. 12B, Section 8.4.1.E., 'increase in nuisance organisms (sea grass) or conditions which may require action to prevent detrimental impact to plant operating equipment.' Unit 2 down powered to 50% on 08/16/00 @ 0810 hrs. Sea grass accumulation [was] mitigated. Unit 2 returned to 100% power on 08/17/00 @ 0835 hrs. Reference Tech. Spec. Appendix B, EPP 4.1."

The licensee plans to notify the NRC resident inspector.
