[en] Improved tritium control is needed today to meet toughening regulatory standards covering radioactive emissions and radiation hazards to nuclear workers. This can be accomplished by the application of zero leak tightness technology with leak tight confinement areas and highly efficient vapor recovery. Leakage occurs because of our failure to test equipment at operational conditions prior to installation and this in turn allows inadequate design and manufacturing procedures. Zero leak tightness in process systems can be accomplished by the use of (a) fewer joints; (b) seal welding; (c) improved gasketing design; (d) live loaded precision stuffing boxes; (e) bellows seal and diaphragm valves; (f) magnetic couplings for valves, pumps, and blowers. The improvements are available today
