Abstract : A modification to provide protection system test capability during operation, now lacking, at the SM-1A is described. The proposed installation allows complete testing of most of the process channels, from sensing element through final protective action. Where direct test of sensing element is not feasible, an indirect test of the sensing element and operational test of the other components in the channel is accomplished. The neutron monitoring system is not changed, but duality of operative components receiving signals from the neutron monitoring system is provided. (Author)
