AGREEMENT STATE REPORT - FIXED GAUGE STUCK SHUTTER
The following was received from the State of Texas via email:
"On March 31, 2015 the Agency [Texas Department of State Health Services] was notified by the radioactive materials reciprocity coordinator that it received a notice of an engineering company scheduled to complete work on a nuclear source stuck shutter. The licensee [Westlake Longview Corporation] was called without contact. A message was left on voicemail. The engineering company was contacted and stated that it was hired to complete work on a sealed source gauge for level measurements due to a stuck shutter. The item is a Ronan Model 4F6S, Cs-137, 40 mCi, Serial Number M7352. The investigation into this case is ongoing. Further updates will be provided in accordance with SA 300 guidelines."

SEISMIC MONITOR NOT AVAILABLE FOR EMERGENCY PLAN ASSESSMENT
"Three Mile Island Station has completed a review of seismic monitor performance. The seismic monitor is currently operable however, this review identified 1 time in the past 3 years that the seismic monitor was inoperable such that emergency classification at the ALERT level could not be obtained with site instrumentation. The seismic monitor was determined to be inoperable on the following date:
1) August 7, 2012
''This unplanned inoperable condition of the seismic monitor was entered into the Three Mile Island Corrective Action Program when it occurred.
"While Exelon procedural direction allowed the use of offsite sources to obtain seismic data when the seismic monitor is incapable of assessing emergency plan Emergency Action Levels (EALs), this was not explicitly referenced in the approved EALs. The loss of assessment capability is reportable to the NRC within 8 hours of discovery in accordance with 10 CFR 50.72(b)(3)(xiii). This report is required per 10 CFR 50.72(a)(1)(ii) as an event that occurred within 3 years of the date of discovery.
"The licensee has notified the NRC Resident Inspector."

SEISMIC MONITOR NOT AVAILABLE FOR EMERGENCY PLAN ASSESSMENT
"Braidwood Generating Station has completed a review of seismic monitor performance. The emergency preparedness plan requires seismic monitoring instruments to diagnose an earthquake for emergency action levels (EAL) HA4 (natural and destructive phenomena affecting vital areas) or HU4 (natural and destructive phenomena affecting the protected area). Contrary to that requirement, this review identified 5 times in the past 3 years that the seismic monitor was non-functional such that emergency classification at the ALERT or UNUSUAL EVENT level could not be obtained with site instrumentation.
"The seismic monitor is currently functional; however, the seismic monitor was determined to be non-functional on the following dates:
1. April 24, 2012
2. December 5, 2012
3. December 20, 2012
4. June 17, 2013
5. October 8, 2014
"These non-functional conditions of the seismic monitor have been corrected and were entered into the Braidwood Corrective Action Program.
"While Exelon procedural direction allowed the use of offsite sources to obtain seismic data when the seismic monitor is incapable of assessing emergency plan Emergency Action Levels (EALs), this was not explicitly referenced in the Braidwood approved EALs. The loss of assessment capability is reportable to the NRC within 8 hours of discovery in accordance with 10 CFR 50.72(b)(3)(xiii). This report is required per 10 CFR 50.72(a)(1)(ii) as an event that occurred within 3 years of the date of discovery.
"Corrective actions are in progress.

ACCUMULATION OF SAMPLE CYLINDERS IN THE CHEMISTRY LAB EXCEEDS AMOUNT ALLOWED
"Event Summary: An amount of Uranium greater than that analyzed in the associated HAZOP [Hazardous Operation] for the Chemistry Laboratory is present in the laboratory. The HAZOP states that approximately 5 kg at any given time, and a maximum of 9 kg per year, will exist in the laboratory. This HAZOP was never updated for changes in customer orders and the resultant accumulation of 1S cylinders which has exceeded the original 9 kg limit.
"Nuclear Criticality Safety (NCS) staff have identified the condition as stable and safe. At no time were the enrichment levels or quantities of U235 in an unsafe condition.
"This is a condition different than that analyzed in the Integrated Safety Analysis (ISA).
"An NCS posting has been applied to prevent the removal or introduction of any material until a detailed evaluation of the condition and measures necessary for resolution are determined."
Samples in 1S cylinders are provided to the Chemistry Lab which is located in the CRDB [Chemistry Receipt Dispatch Building] prior to shipment of product to the customer. Due to a slowdown in business these samples have accumulated to an amount exceeding the approved ISA which had not been updated to reflect current business practices. This condition was discovered by the MC & A [Material Control & Accounting] Group during a review of the process and will be addressed at an Emergency ISA Meeting on Monday, 3/30/15.
