This proposed action is to replace the ATR plant nuclear instrumentation and control components with functionally equivalent equipment. The replacement components consist of multiple channels with neutron detector drives, cables, conduit, monitor drawers, records, and displays. Correction of legacy issues includes equipment seismic anchorage and installation of additional conduit supports. Activity may require functionally equivalent temporary or permanent modifications to the Reactor Data Acquisition System (RDAS) input interface.
