WebAn increasing reaction rate constant was observed with increasing temperature, (excluding the 35 degree trial whose correlation coefficient would support that it cannot be represented well by a linear fit). From the linear regression taken for an assumed 2nd order reaction plot, the reaction rate constant was taken to be the slope. The The light-water reactor produces heat by controlled nuclear fission. The nuclear reactor core is the portion of a nuclear reactor where the nuclear reactions take place. It mainly consists of nuclear fuel and control elements. The pencil-thin nuclear fuel rods, each about 12 feet (3.7 m) long, are grouped by the hundreds in bundles called fuel assemblies. Inside each fuel rod, pellets of uranium, or m…
