This required that personnel mechanically break the stack starting from the top while working from suspended or attached temporary working platforms. Initially explosive demolition was rejected in favour of mechanical disassembly because the former posed unmanageable safety risks. For example, proximity to a building where irradiated fuel was handled presented a major problem because parts of this building were located within the height range of the stack. A misdirected fall could have had serious consequences.

External access platforms. ; — Flame or plasma cutting. g. drilling and spalling, use of rock splitters (hydraulic wedges, expanding grout), use of jackhammers; — Diamond wire sawing; — Circular diamond wheel sawing; — Thermic lances. Concrete fragmentation techniques result in an amount of broken concrete that needs to be managed. This material can be dropped inside the stack, but measures are often necessary to prevent this material falling outside 23 the stack.
