Scientific Design of Purdue University Multi-Dimensional Integral Test Assembly (PUMA) for GE SBWR

摘要

The scientific design of the scaled facility (PUMA) has been carried out under the project 'Confirmatory Integral System Testing for GE SBWR Design'. The design was based on the three level scaling method developed for this task. The first level of scaling is based on the integral response function. The second level scaling is for the boundary flow of local phenomena and constitutive relations. The facility has 1/4 height and 1/100 area ratio scaling. This corresponds to a volume scale of 1/400 and power scaling of 1/200. The time will run twice as fast in the model as predicted by the present scaling method. The PUMA is scaled for full pressure and is intended to operate at and below 150 psia following scram. The facility models all the major components of SBWR.
