RADIATION SITUATION AND ITS EVALUATION WHILE MAKING AN OPENING IN THE UPPER STRUCTURES OF A SHUTDOWN URANIUM‑GRAPHITE REACTOR

JOURNAL: 2022, 18, p. 43-56

AUTHORS: A.O. Paviluk, S.G. Kotlyarevskij, R.I. Kan, V.S. Zagumennov, E.S. Paderin, A.A. Sheshin, E.A. Savran

ANNOTATION:

This article presents the results and methods allowing to evaluate the changes in the radiation situation during the experimental implementation of graphite stack dismantlement methods at ADE-5 PUGR (JSC PDC UGR site). It considers the approaches proposed to limit the increasing gamma radiation levels at work places when an opening is arranged in the upper structures of a shutdown uranium-graphite reactor providing access to the graphite stack and evaluates their effectiveness.

Keywords: decommissioning, dismantling, radiation fields, uranium-graphite reactor, gamma radiation, radiation factor, radioactive waste.
