AGREEMENT STATE REPORT - SHUTTER FAILURE
The following information was received via email from the Illinois Emergency Management Agency:
"On December 19, 2012 this general license registrant called to advise that a shutter on one of their process gauges had failed. The registrant had discovered the failure as a result of conducting their routine 6-month safety checks of the device. A makeshift shield was placed over the beam opening following the manufacturer's instructions, pending repair. Arrangements were made to have a field engineer from the company come to the site the next day to replace the shutter. No exposures to operating personnel were reported due to the circumstances of the gauge installation and low activity of the source involved.
"Source/Radioactive Material: SEALED SOURCE GAUGE
"Radionuclide: AM-241, 0.025 Ci, 0.925 GBq
"Manufacturer: QSA GLOBAL
"Model Number: AMC.P6
"Serial Number: 7734AR"
Illinois Item Number: IL12018

PARTIAL LOSS OF EMERGENCY ASSESSMENT DURING PLANNED MODIFICATIONS
"Calvert Cliffs Nuclear Power Plant will begin a planned modification of the Unit 1 and Unit 2 Plant Process Computers (PPC's) and associated network infrastructure on December 18, 2012. This includes the Emergency Response Data System (ERDS) communication with the NRC Operations Center. This work will require the TSC, OSC and subsequently EOF to lose data flow from the plant data network for a period of approximately 36 hours. During this time, the following systems will be impacted for the duration of maintenance:
1. ERDS will be out of service.
2. Plant Data will not reach the TSC and OSC from the plant data network.
3. TSC Computer data transfer to the EOF only will be out of service.
4. Chemistry DAS remote monitoring capability will be lost.
5. Plant parameter data will not be available on the site's LAN network.
"Once the schedule maintenance starts, the systems (listed above) can be returned to service within 1 hour. Should an emergency be declared during this period, the Control Room will continue to have the capability to retrieve plant data inputs to assess plant conditions and perform core damage assessment. Control Room Emergency response personnel will use emergency response procedures (ERPIP 106) to disseminate plant parameter data to the effected Emergency Response Facilities. MIDAS (Meteorological Data) will continue to be operational at the site. Compensatory measures exist within the Calvert Cliffs Emergency Response procedures to provide plant data in the event of an actual Emergency to the NRC Operations Center until the ERDS can be returned to service."
The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM BRIAN HAYDEN TO S. SANDIN ON 12/20/2012 AT 1035 EST * * *
On 12/20/2012 at 0200 EST, the plant process computer and associated network infrastructure was restored to service. The licensee will notify the NRC Resident Inspector.
