In-Pile Loop Cryogenic Refrigerator
Supply 1150 w of refrigeration at the transfer-line manifold with a minimum of 950 w at the entrance to the in-pile test loops while maintaining a test-sample temperature within the range of 30° to 540°R to ±1°R.
Be capable of holding concurrently any single sample temperature in this range of 30° to 540°R in separate test loops (one under irradiation and another in the pool not under irradiation) provided that the total heat load of the test loops does not exceed 950 w at 24° R under steady-state conditions.
The refrigeration system must provide for three interchangeable test loops to be connected at one time.
The transfer lines must be sufficiently flexible to permit insertion of a test loop into the reactor beam port and 180° rotation, then translation into a hot cave port which is used for removal of test samples from the loops.
