Thermite contains its own supply of oxygen and does not require any external source of air. Consequently, it cannot be smothered, and may ignite in any environment given sufficient initial heat. It burns well while wet, and cannot be easily extinguished with water—though enough water to remove sufficient heat may stop the reaction. [22]
The CNRS project EVOL (Evaluation and viability of liquid fuel fast reactor system) project, with the objective of proposing a design of the molten salt fast reactor (MSFR), [72] released its final report in 2014. [73] Various MSR projects like FHR, MOSART, MSFR, and TMSR have common research and development themes. [74]
Caesium-137 concentration in the air, 19 March 2011. Radioactive materials were dispersed into the atmosphere immediately after the disaster and account for most of all such materials leaked into the environment. 80% of the initial atmospheric release eventually deposited over rivers and the Pacific Ocean, according to a UNSCEAR report in 2020.

The 2011 Fukushima Daiichi nuclear disaster, the worst nuclear incident in 25 years, displaced 50,000 households after radioactive material leaked into the air, soil and sea. [1] Radiation checks led to bans on some shipments of vegetables and fish. [2] Map of contaminated areas around the plant (22 March – 3 April).
The outflow of the plant is put into the discharge from Encina Power Station for dilution, for a final salt concentration about 20% higher than seawater. Most desalination plants discharge water with about 50% extra salt, which can lead to dead spots in the ocean, because the super-salinated brine does not mix well with seawater. [16]
The water temperature in normal operating conditions is held below 50 °C (120 °F). [8] Radiolysis, the dissociation of molecules by radiation, is of particular concern in wet storage, as water may be split by residual radiation and hydrogen gas may accumulate increasing the risk of explosions. For this reason the air in the room of the pools ...
The pipeline empties the water into a sea water intake sump on the shore where 3 vertical turbine pumps of variable discharge up to a maximum of 4,000 m 3 /h each are used to pump water into the plant. The average intake flow is 9,000 to 10,000 m 3 /h, and the average product water output of the plant is about 4,000 m 3 /h. The system is ...
This is contrary to many media reports, [27] which have popularized the concept as a candle-like reactor with a burn region that moves down the length of a fuel section. By replacing a static core configuration with an actively managed "standing wave" or "soliton", however, TerraPower's design avoids the problem of cooling a moving burn region ...
