Corium may be completely retained by the reactor vessel, or the reactor floor or some of the instrument penetration holes can be melted through. [9] The thermal load of corium on the floor below the reactor vessel can be assessed by a grid of fiber optic sensors embedded in the concrete. Pure silica fibers are needed as they are more resistant ...
A large circular mimic display for every channel or core map is on the left. The distribution of power density in the reactor is measured by ionization chambers located inside and outside the core. The physical power density distribution control system (PPDDCS) has sensors inside the core; the reactor control and protection system (RCPS) uses ...
Another factor which probably contributed to the start of the Oklo natural nuclear reactor at 2 billion years, rather than earlier, was the increasing oxygen content in the Earth's atmosphere. [4] Uranium is naturally present in the rocks of the earth, and the abundance of fissile 235 U was at least 3% or higher at all times prior to reactor ...
On the basis of the T-15 there will be created a nuclear fusion–fission hybrid reactor, intended to use the neutrons generated by a core fusion reactor component to incite fission in otherwise nonfissile fuels, and to explore the feasibility of such a system for power generation. [8] [9] Assembly of the magnetic coils was finished in August ...

In fusion power plants, neutrons will be present at fluxes in the order of 10 18 m −2 s −1 and will interact with the material structures of the reactor by which their spectrum will be broadened and softened. [citation needed] A fusion relevant neutron source is an indispensable step towards the successful development of fusion energy. [4]
Laboratory scientists are collaborating with researchers on fusion science and technology at other facilities, including DIII-D in San Diego, EAST in China, JET in the United Kingdom, KSTAR in South Korea, the LHD in Japan, the Wendelstein 7-X (W7-X) device in Germany, and the International Thermonuclear Experimental Reactor (ITER) in France.
The Lockheed Martin Compact Fusion Reactor (CFR) was a fusion power project at Lockheed Martin’s Skunk Works. [1] Its high-beta configuration, which implies that the ratio of plasma pressure to magnetic pressure is greater than or equal to 1 (compared to tokamak designs' 0.05), allows a compact design and expedited development. The project ...
