At 12:15 PM on 8/20/04, it was discovered … At 12:15 PM on 8/20/04, it was discovered that actions performed on 7/16/04 in support of Dry Fuel Storage activities to defeat the Railroad Access Area Radiation Monitor alarm horn had also defeated the actuation capability of the Railroad Access Process Radiation monitors. Per Technical Specifications, the process monitors are required to be operable "during movement of irradiated fuel assemblies within the Railroad Access Shaft, and above the Railroad Access Shaft with the Railroad Access Shaft Equipment Hatch open." Contrary to the Tech Spec requirement, two loaded Dry Fuel Storage Casks were lowered in the Railroad Shaft, one on 8/2/04 and the second on 8/16/04, with the radiation monitors inoperable. During this period the automatic isolation and re-alignment of Reactor Building Zone lll, automatic start of Reactor Building Recirculation Fans, and the automatic starts of SGTS and CREOASS would not have actuated from a HI-HI Radiation condition in the Railroad Access Shaft. Actual radiological conditions observed during the transfer of the casks in the railroad shaft would not have resulted in the need for system actuation. All other instruments in the Reactor Building ventilation system which actuate these systems were operable as required by Tech Specs. The jumpers which defeated the actuation capability were removed on 8/20/04 at 1400 (hrs.).</br>This event is considered reportable under 50.72(b)(3)(v)(C) as a loss of safety function.</br>The NRC Resident Inspector was notified..
