Unit 6 also shortly began on 1 July 1983. Unit 5 was scheduled to become operational on 7 November 1986, and reactor 6 in 1994 inside a new block of buildings. [3] The two RBMK-1000 units measured 11.8 m (39 ft) tall and 7 m (23 ft) in diameter, and were installed with two large portal cranes. [4]

The New Safe Confinement design is an arch-shaped steel structure with an internal height of 92.5 metres (303.5 ft) and a 12-metre (39.4 ft) distance between the centers of the upper and lower arch chords. The internal span of the arch is 245 metres (803.8 ft), and the external span is 270 metres (885.83 ft).
A BWR's containment consists of a drywell, where the reactor and associated cooling equipment is located, and a wetwell. The drywell is much smaller than a PWR containment and plays a larger role. During the theoretical leakage design basis accident, the reactor coolant flashes to steam in the drywell, pressurizing it rapidly.
A $100 million air intake shaft at the Waste Isolation Pilot Plant reached its final depth of 2,275 feet. Nuclear waste managers said they needed the shaft to add air for underground workers to ...
In 1982, Congress established a national policy to solve the problem of nuclear waste disposal. This policy is a federal law called the Nuclear Waste Policy Act, [20] which made the U.S. Department of Energy (DOE) responsible for finding a site, building, and operating an underground disposal facility called a geologic repository.
The plant processes liquid radioactive waste, which during the technological process is cemented and transformed into safer for storage and disposal. At the moment, the plant has processed 34 "packages", which, after exposure and radiation control, will be directed to burial in a special near-surface storage of solid radioactive waste.
Multipurpose Constor Storage, Transport, and Disposal Cask A centralized storage facility using dry casks is located at Ahaus . [ 18 ] As of 2011, it housed 311 casks: 305 from the Thorium High Temperature Reactor , 3 from the Neckarwestheim Nuclear Power Plant , and 3 from the Gundremmingen Nuclear Power Plant . [ 18 ]
