[2]: 5 [3] The large glass walls enabled public viewing of the reactor room's interior, showcasing the activity inside. [7] The first floor, partly covered by the outdoor plaza, housed the reactor, laboratory, crystal spectrometer, counting room with a nuclear densometer, classrooms, restrooms, and offices. The second floor contained the ...
Chernobyl Reactor 5 was initially abandoned after the 1986 disaster, but final decisions to halt work occurred in 1989 as safety and cost concerns grew. The Ukrainian government fully decommissioned the Chernobyl Nuclear Power Plant in 2000, closing down operations of the remaining active reactors and stopping any possible revival of Reactors 5 ...

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).
Hanford’s historic B Reactor, the world’s first full-scale nuclear reactor, went critical on Sept. 26, 1944. Wigner’s team had designed the Hanford reactors to house 1,600 process tubes.
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.
In August 2021 Energoatom and Westinghouse signed a contract for construction of 2 Westinghouse AP1000 reactors as blocks 5 and 6 at the Khmelnitskyi nuclear power plant. [25] Unit 3 and 4 will be completed with the VVER-1000 design. Workers from the Zaporizhzhia Nuclear Power Plant that have fled the area are now working on units 3 and 4.
The Chernobyl Nuclear Power Plant sarcophagus or Shelter Structure (Ukrainian: Об'єкт "Укриття", romanized: Ob'yekt "Ukryttya", Russian: Объект «Укрытие», romanized: Ob"yekt «Ukrytiye») is a massive steel and concrete structure covering the nuclear reactor number 4 building of the Chernobyl Nuclear Power Plant.
