LOSS OF SPDS COMPUTER

"This 8-hour non-emergency report is being made based upon requirements of 10CFR50.72(b)(3)(xiii) which states, 'The licensee shall notify the NRC as soon as practical and in all cases within eight hours of the occurrence of any event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability (e.g., significant portion of control room indication, Emergency Notification System, or offsite notification system).' An example of a major loss of emergency assessment capability is when the Safety Parameter Display System (SPDS) computer is unavailable for greater than eight hours.

"At 0830 EDT on Wednesday, September 02, 2009 the SPDS Computer was found by the computer department to have one of three interface modules failed. The interface module transports data from the radwaste computer to SPDS. The failure resulted in a loss of 187 SPDS points.

"All other SPDS points along with Plant Process Computer functions are available. Information Technology Department personnel are investigating the cause of the interface module failure, which is currently unknown.

"No other control room emergency assessment capabilities have been adversely affected. All Control Room panel indicators and annunciators are responding properly."

The licensee notified the NRC Resident Inspector.

"The Safety Parameter Display System [SPDS] was returned to service at 1030 EDT on 9/10/2009. Degraded SPDS components have been repaired and SPDS has been verified to be functional and capable of meeting all required design functions.

"The licensee has notified the NRC Resident Inspector."

STATE OFFSITE NOTIFICATION DUE TO NOT MEETING PERMIT REQUIREMENTS

"The Minnesota State Pollution Control Agency and State Department of Emergency Management were notified today, September 10, 2009, that Monticello did not meet the National Pollutant Discharge Elimination System (NPDES) Permit.

"Samples from a new monitoring well near the reactor building showed low levels of tritium greater than normal background but below Environmental Protection Agency drinking water standards. The concentration of tritium is below any radiological reporting levels established in station procedures. No elevated levels have been detected in any of the other permanent plant monitoring wells. Therefore, we have no indications that there has been a release of tritium beyond the site from this source. The station will continue to monitor, sample and investigate the source of the tritium."

The licensee notified the NRC Resident Inspector.
