In October, 1976, the UNI Reactor Technology Section received approval and funding for the 189 program Activated Corrosion Produce (Crud) Behavior. This is a two-year program to evaluate methods of controlling activated corrosion product formation, transport, and deposition to reduce dose rates and personnel exposure around the primary coolant system. A new crud sampling system is required because the existing crud sampler in 109, as well as the other primary coolant sample points, cannot give a reliable sample of particulates in the primary coolant. Passing the coolant at low flow through 200 to 500 feet of half-inch stainless tubing precludes obtaining a sample representative of the crud concentration in the recirculating primary coolant. The purpose of this report is to outline the design requirements for a primary coolant crud sampler in support of the Engineering Request Primary Coolant Crud Sampler submitted October 29, 1976 for the design, procurement, and installation of the sampler.
