Russian nuclear microreactor Shelf-M. A nuclear microreactor is a type of nuclear reactor which can be easily assembled and transported by road, rail or air. [1] Microreactors are 100 to 1,000 times smaller than conventional nuclear reactors, and range in capacity from 1 to 20 MWe (megawatts of electricity), compared to 20 to 300 MWe (megawatts of electricity) for small modular reactors (SMRs ...
MH-1A was the first floating nuclear power station.Named Sturgis after General Samuel D. Sturgis, Jr., this pressurized water reactor built in a converted Liberty ship was part of a series of reactors in the US Army Nuclear Power Program, which aimed to develop small nuclear reactors to generate electrical and space-heating energy primarily at remote, relatively inaccessible sites.

3 × 45,000 lb/h (5.7 kg/s) Stirling boilers with chain grate stokers, The total evaporative capacity was 229,000 lb/h (28.8 kg/s), steam conditions were 200 psi and 620–650 °F (13.8 bar, 327–343 °C), and supplied steam to: Turbo-alternators: 2 × Parsons 10 MW turbo-alternators, 3000 rpm, generating at 6.6 kV
For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower. Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.
The overall thermal efficiency of the A station in 1963-64 was 20.16 per cent. [4] In 1959 the B station had four Parsons 25 MW turbo-alternators and one Metropolitan Vickers 56.9 MW twin set. [5] By 1963-64 the B station had 1 × 60.27 MW and 1 × 60 MW generators. [4] The steam capacity of the associated boilers was 2,305,000 lb/hr (290.4 kg/s).
Unit 1 was a 460 MW boiling water reactor from the BWR-3 design iteration introduced in 1965 and constructed in July 1967. After the plant became severely damaged in the TÅhoku earthquake and tsunami , loss of reactor core cooling led to three nuclear meltdowns, three hydrogen explosions, and the release of radioactive contamination in Units 1 ...
Together with the adjacent 2,106 MW La Grande-2-A generating station (LG-2-A), commissioned in 1991–1992, it uses the reservoir and dam system of the Robert-Bourassa Reservoir to generate electricity. The two plants taken together account for more than 20% of Hydro-Québec's total installed capacity of 36,810 MW in 2009. [1]
Rolls-Royce Marine Power Operations at Derby was the centre for design and manufacture of the UK's submarine reactors, and remains so today. The Ministry of Defence 's Vulcan Naval Reactor Test Establishment (NRTE) , at Dounreay , tested each reactor core design prior to its installation in nuclear submarines.
