AGREEMENT STATE REPORT - ABNORMAL EXCESS LOSS OF WATER INTO DRAIN SYSTEM FROM DE-IONIZATION SYSTEM
The following information was provided from the State of Nebraska via e-mail:
"The Nebraska DHHS [Department of Health and Human Services] was notified on March 23, 2009 at 0825 by the Radiation Safety Officer (RSO) for Becton Dickinson in Broken Bow, Nebraska. On March 22, 2009 in the evening, the RSO received a call from one of the pool irradiator operators. During the operator's weekly sterilizer checks, he noticed that the pool water make-up meter indicated the pool had used 1,103 gal for the week. Normal usage is about 120 gal/week. Investigation on the next morning revealed a bleed valve on the D.I. [de-ionizing] water system was cracked open, allowing D.I. water to flow to drain. This was not readily apparent because the hose goes down into the drain. The RSO closed the valve, recorded the current meter reading, noting the meter had used about 100 gal overnight. The RSO intends to check the reading Tuesday morning to see if closing the valve solved the problem. This water leaking does not affect the level of the pool water.
"Nebraska DHHS has notified Randy Erickson, NRC, Region IV
"Event report ID No. NMED NE090006"

"The next [meter] reading on 3/29 was also elevated at 336 gallons. The next readings were 201 gallons on 4/5, 244 gallons on 4/12 and 231 gallons on 4/19. Levels had dropped, but were still slightly higher than expected. The licensee's maintenance technicians discovered that the oil pressure safety switch in the compressor unit of the water chiller system was tripping off and shutting down the unit. The safety switch was replaced on May 1.
"In addition, the licensee installed a beacon and an audible alarm to alert an operator when the chiller oil pressure safety switch tripped out. This prevents the chiller from being down for any length of time without anyone's knowledge. The safety switch continued to trip out occasionally but was reset immediately so the water use returned to normal readings of 110 gallons on 5/3, 60 gallons on 5/10 and 63 gallons on 5/17. The licensee continued the investigation and parts were obtained to repair the compressor unit. On 5/18, the licensee replaced the oil pump, pressure sensor and changed the oil in the compressor. The unit ran for the next 24 hours without any further issues. The licensee said they would continue to monitor the situation closely, but they believe the issue has been resolved."

UNIT 1 STEAM GENERATOR FOUND IN AN UNANALYZED CONDITION RELATED TO GAPS ON SEISMIC WASHER PLATES
"At 1334 on March 22, 2009, while Unit 1 was in Mode 3, replacement steam generator (RSG) 1-3 was conservatively determined to be in an unanalyzed condition in that seismic washer plates were found to have nonconforming gaps on two of the four steam generator support columns. A plant walk down discovered that the two washer plates were not seated in the column adapter due to an interfering weld on the interior recess of the column adapter. Because of this condition, Technical Specification 3.0.3 was entered for Unit 1.
"At 1536 on March 22, 2009, a shim was installed between the washer plate and the column adapter at each of the two non-conforming locations on RSG 1-3 of sufficient thickness to clear the weld metal interfering with washers. This action brought the support columns for RSG 1-3, support foot joints into compliance with the full design capacity. Technical Specification 3.0.3 was exited for Unit 1 at that time.
"This issue was discussed with US NRC DCPP Senior Resident."
