Abstract
An arrangement of reactor coolant pump seals arranged in a generally annular stack with a plurality of stacking spacers in a test housing for emplacement in a chemical decontamination test loop enables a variety of flow characteristics to be simulated by varying the detailed arrangement of the RCP seals and supporting structure in the test housing. By adjusting parameters such as fluid chemistry, gross flow, pressure, and temperature in a controlled manner with systems incorporated into the test loop, additional information can be obtained regarding the feasibility of any specific decontamination process. The magnitude of process fluid flow across particular surfaces of one or more RCP seal components can be predetermined by selecting the placement, number and dimensions of penetrations in a flow distribution tube through which the process fluid enters the housing. The penetrations feed the process fluid to channels in selected stacking spacers, thereby directing the process fluid flow to selected seal surfaces. The arrangement of the stacked seal assembly also assures that each of the seal components will experience a process fluid flow similar to what would be experienced in an in situ decontamination procedure in an RCP.
