A nuclear power plant (18) and its heat exhanger (26) are enclosed in an envelope (22) which is suspended above a bored shaft (14) from a support stem (30). When appropriate, the stem (30) can be melted by a furnace (34) to drop the envelope (22) to the bottom of the shaft (14). Sand (42) can then b
A nuclear power plant (18) and its heat exhanger (26) are enclosed in an envelope (22) which is suspended above a bored shaft (14) from a support stem (30). When appropriate, the stem (30) can be melted by a furnace (34) to drop the envelope (22) to the bottom of the shaft (14). Sand (42) can then be dropped onto the envelope (22) through a drainage pipe (46). While the nuclear power plant (18) is operating and suspended in the shaft, spent fuel rods (70) are dropped into a sand blasting machine's hopper (130), mixed with sand and dropped into a bag (134) containing a small explosive device. The bag (134) is then dropped to the bottom of the shaft (14) and the explosive detonated to scatter the contents of the bag (134). Optionally, more sand or earth is then added to reduce heat and radiation to acceptable levels.
