Carminite (PbFe 3+ 2 (AsO 4) 2 (OH) 2 [8]) is an anhydrous arsenate mineral containing hydroxyl. [citation needed] It is a rare secondary mineral that is structurally related to palermoite (Li 2 SrAl 4 (PO 4) 4 (OH) 4). [8] Sewardite (CaFe 3+ 2 (AsO 4) 2 (OH) 2) is an analogue of carminite, with calcium in sewardite in place of the lead in ...
When the reactor is prompt critical, the time to double the power is of the order of 10 microseconds. The duration necessary for temperature to follow the power level depends on the design of the reactor core. Typically, the coolant temperature lags behind the power by 3 to 5 seconds in a conventional LWR. In the SL-1 design, it was about 6 ...
RELAP5-3D is an outgrowth of the one-dimensional RELAP5/MOD3 code developed at Idaho National Laboratory (INL) for the U.S. Nuclear Regulatory Commission (NRC). The U.S. Department of Energy (DOE) began sponsoring additional RELAP5 development in the early 1980s to meet its own reactor safety assessment needs.
The stable salt reactor (SSR) is a nuclear reactor design proposed by Moltex Energy. [118] It represents a breakthrough in molten salt reactor technology, with the potential to make nuclear power safer, cheaper and cleaner. The modular nature of the design, including reactor core and non-nuclear buildings, allows rapid deployment on a large scale.
However, in September 2013, Marat Mustasin, general director of Atomenergoproekt, clarified in an interview with Nuclear.Ru that although the geological survey at Rooppur would be conducted under the VVER-TOI project, a decision on which specific reactor design the plant would be adjusted to would be made later.

During atomic layer deposition, a film is grown on a substrate by exposing its surface to alternate gaseous species (typically referred to as precursors or reactants). In contrast to chemical vapor deposition, the precursors are never present simultaneously in the reactor, but they are inserted as a series of sequential, non-overlapping pulses.
This reactor is the oldest operating in the nation and has undergone numerous power upgrades, renovations, and other changes. The reactor serves the research purposes of the Penn State Department of Mechanical and Nuclear Engineering as well as researchers from industry and other universities.
A number of reactor designs, like the Integral Fast Reactor, have been designed for this rather different fuel cycle. In principle, it should be possible to derive energy from the fission of any actinide nucleus. With a careful reactor design, all the actinides in the fuel can be consumed, leaving only lighter elements with short half-lives ...
