Title	Scaffolding Affecting Safety Related Equipment
Event Description	At 1500 [CDT], a concern was raised with regard to scaffolding that had been constructed around safety related equipment in the Auxiliary Building which contains both trains of safety injection and containment spray. As a result T.S. 2.0.1 was entered (which is the Fort Calhoun equivalent to standard T.S. 3.0.3). The scaffolding in question was removed and the equipment was returned to operable status and T.S. 2.0.1 was exited at 1726 [CDT]. The NRC Resident Inspector has been notified. * * RETRACTION FROM ERICK MATZKE TO HOWIE CROUCH @ 2027 EDT ON 5/27/11 * * * Following the initial report, Fort Calhoun performed a seismic analysis of the impact of the scaffolding previously reported to determine if the equipment in the room would be capable of performing its required safety functions. The evaluation determined that the safety related function of the affected equipment would be able to be accomplished. Therefore, this event is being retracted. Notified R4DO (Haire). The licensee has notified the NRC Resident Inspector of this retraction.
