“…A possible uncertaintyin the results of both Phase I and II is the loss of tritium from the BEATRIX-IIsweep gas system by permeationof tritium through the stainlesssteel sweep gas tubing and canister walls. In the original design analysesof Phase I (Bauer 1988) tritium losses from permeation through the barrier-coated componentswere predicted to be low (approximately I%), but the uncertaintyin this ap_lysis remains an issue, lt was…”
