BERYLLIUM POISONING IN THE MARIA REACTOR

K. Andrzejewski, T. Kulikowska - Institute of Atomic Energy, Poland

M. Bretscher, J. Matos - Argonne National Laboratory, USA

ABSTRACT

The poisoning of beryllium blocks initiated by the Be-9(n,a) reaction is discussed in this paper. The present status of the methods used to evaluate Li-6 and He-3 poison concentrations in the MARIA reactor are described. On the basis of conservative assumptions the magnitude of the problem is evaluated. Implications for the reactor operation are formulated, comprising the necessity of keeping long term reactor operation records with special emphasis on beryllium history.
