A 14-day fire protection system impairment was entered and a continuous compensatory fire watch with backup suppression was stationed prior to removing the system from service for testing. Upon failure of the surveillance test, the impairment remained in effect and the continuous fire watch remained stationed pending investigation/repair by Maintenance. On 9/2/2011 at approximately 1600 (CDT), Mechanical Maintenance personnel informed Operations that the sprinkler suppression piping was found to be fouled and not capable of passing flow. The intake sprinkler system is relied upon in part to satisfy an exemption for the station to 10CFR50 Appendix R, Section III.G.2.B concerning separation of components in the intake structure. Based upon the intake sprinkler system being non-functional, this condition is being reported under 10CFR50.72(b)(3)(ii)(B) as an unanalyzed condition affecting plant safety systems.</br>The licensee informed the NRC Resident Inspector.ensee informed the NRC Resident Inspector. +
