HIGH CONDUCTIVITY READINGS IN GAMMA POOL
On 4/22/04, around 13:30 EDT, after the irradiator shielding pool had been vacuumed, pool water conductivity exceeded 100 microsiemens per centimeter. The licensee initiated a change of the resin beds and observed pool water conductivity to decrease, as expected. On 4/23/04, the licensee noticed that pool water conductivity had increased to 110 microsiemens per centimeter. New resin beds are being placed in service today (4/26/04) by 18:00 and its is expected that pool water conductivity will decrease from 201 microsiemens to levels of less than 20 microsiemens per centimeter within 24 to 48 hours at the current recirculation rate through the resin beds. There are no personnel safety issues involved with this incident. The licensee will contact the Operations Center if the expected water pool conductivity does not return to normal operating levels.

SAFETY PARAMETER DISPLAY SYSTEM (SPDS) DECLARED INOPERABLE
"At 1045 hours on 04/22/04, the Safety Parameter Display System (SPDS) portion of the Emergency Response Facility Computer System (ERFCS) was noted to be inoperable due to all outputs being displayed in "magenta" color. Attempts were made to reboot the system, but were unsuccessful. At 1145 hours on 4/22/04, SPDS was returned to service. Therefore, the SPDS had been out of service for 1 hour, which is considered a major loss of emergency assessment capability. This report is being made in accordance with 10CFR50.72(b)(3)(xiii)."
SPDS is not 100% operable, but it does meet the licensee's operability criteria to be declared operable. The licensee is analyzing the problem.
The licensee notified the NRC Resident Inspector.
