TSC AND EOF OUT OF SERVICE DUE TO MAINTENANCE
"At approximately 0930 hours EDT on Thursday, April 12, 2012, the H. B. Robinson Steam Electric Plant, Unit No. 2, Technical Support Center (TSC)/Emergency Response Facility (EOF) air conditioning and charcoal filtration systems will be removed from service to facilitate the replacement of the charcoal filtration media. The duration of work is expected to be approximately 11 hours. Since the unavailability will last greater than 8 hours, this is considered a Loss of Emergency Assessment Capability, and reportable under 10 CFR 50.72(b)(3)(xiii).
"Due to the inability of the TSC/EOF ventilation system to maintain a habitable atmosphere, as a compensatory measure, Emergency Responders assigned to these facilities have been informed to report to the alternate facilities until such time that the TSC/EOF ventilation system has been returned to service.
"TSC/EOF ventilation system maintenance and post maintenance testing is scheduled to be completed by 2030 hours EDT on Thursday April 12, 2012.
"The NRC Resident Inspector has been informed."
* * * UPDATE FROM WARREN WONKA TO HOWIE CROUCH AT 0435 EDT ON 4/13/12 * * *
At 1814 EDT on 4/12/12, maintenance on the TSC/EOF ventilation system was completed and the TSC/EOF was returned to service.

INTERNAL REPORTING REQUIREMENT FOR CRITICALITY SAFETY CONTROLS
"At approximately 8:00 am on April 12, 2012, a criticality safety engineer was notified that waste in the Dry Conversion Process (DCP) area was improperly placed into a designated storage location. Upon investigation, it was determined that waste in the designated location contained materials with a total of less than 5 kg of uranium. As a result, no unsafe condition existed.
"An operator placed a bag of waste adjacent to a partially filled receptacle instead of placing the bag into the receptacle. This resulted in a portion of one of the documented administrative controls for criticality safety, requiring 24 inches separation between waste storage locations, to be degraded. This event is being conservatively reported per internal procedural requirements.
"As an immediate corrective action, the material was removed and transferred to the waste processing area. In addition, a shop wide communication to Fuel Manufacturing Operations is underway to inform operators of the issue.
"Additional corrective actions and extent of condition are being evaluated.
"At no time was an unsafe condition present."
Notifications were sent to state and local agencies and NRC Region II.
