Permanent Storage Areas in CANDU Nuclear Power Plants

Abstract

Historically less than adequate attention was paid to the transient (up to four months) and permanent (longer term) combustible and flammable materials (does not include permanent station cabling, electronic, and mechanical equipment) needed to operate the plant over its life at the design stage. This has resulted in operations and station engineering staff having to accommodate these necessary materials during the operations phase. This paper discusses the challenges and proposes a methodology to redesign the station to safely accommodate these materials on a permanent basis.
