Reactor accident chemistry an update | Cogent OA

A review and discussion of some of the literature on the subject of serious nuclear reactor accidents. This review addresses some biological issues such as the influence of dose rate on the ability of radiation to cause harm, the chemistry of a selection of serious accidents and the behaviour of a series of important fission products and the actinides.

Electrical conductivity of silicon carbide composites …

The electrical conductivity, σ, of silicon carbide (SiC) composites and fibers was measured for temperatures between 20 and 1000 °C in order to estimate the magnitude of magnetohydrodynamic effects for liquid metal blankets and a SiC composite structure. Two types of composites were tested: the first type had a matrix made by chemical vapor

Petroleum coke | Revolvy

2013-3-27 · Petroleum coke Petroleum coke Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter

Vinyl Plank by Jin Sei Corp. Supplier from South Korea

People usually call pvc in a more familiar way as "vinyl". This synthetic compound is essentially a plastic made from a coination of carbon, hydrogen and chloride. pvc is a 100% recyclable product that requires minimal energy and natural resources to produce, and itâ creates a softer floor than hardwood or tile, making it more resistant to dents and scratches. flooring made of pvc is

Anthracite - IPFS

Anthracite is a hard, compact variety of coal that has a submetallic luster.It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coal except for graphite.. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92.1% and 98%.
