Abstract
The MISTRAL code was used to analyze the BEATRIX-II experimental results of Li,O ring samples. The
analysis included the change in inventory due to different temperature transients, the end-of-life inventory of the
Phase I ring sample, and the analysis of the transient tritium release history of both Phase I and Phase II ring
samples. The change in inventory results were used in order to obtain a set of input data that will reproduce these
results. Using the same input data, MISTRAL was able to predict the end-of-life inventory of the sample. In all the
cases, the calculations indicated that most of the tritium was present in the bulk, leading to the assumption that
LiOT formation inside the grains is the key mechanism in controlling the tritium inventory in these cases.
1. Introduction
The most recent data available on the tritium re-
lease from Li,O comes from the BEATRIX-II experi-
ment (see Slagle et al. [l]), in which the in-situ tritium
release from Li,O samples was measured under differ-
ent conditions.
The experimental results were analyzed using the
