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.
The reactor was now producing only 5% of the minimum initial power level prescribed for the test. [21]: 73 This low reactivity inhibited the burn-off of xenon-135 [21]: 6 within the reactor core and hindered the rise of reactor power. To increase power, control-room personnel removed numerous control rods from the reactor. [27]
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 ...
They are typically 40 or more feet (12 m) deep, with the bottom 14 feet (4.3 m) equipped with storage racks designed to hold fuel assemblies removed from reactors. A reactor's local pool is specially designed for the reactor in which the fuel was used and is situated at the reactor site. Such pools are used for short-term cooling of the fuel rods.
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 ]
