The use of a neutron poison--e.g. boric acid--dissolved in primary coolant to control slowly varying reactivity effects is considered. Chemical shim provides increased power density and lowers control-rod requirements. The decrease of negative temperature coefficient does not appear to be a safety hazard or to limit fuel burnup. Studies on the Yankee and Saxton reactors indicate so far that problems in reactor functioning or safety from chemical and physical characteristics of boric-acid containing coolant are minimal.
