Nuclear Power Engineering Water is a better coolant than a gas (like CO₂, He, N₂ etc.), because it Is a better neutron moderator as well Has a better heat transfer characteristics, and it can be pressurised to attain a high temperature All of these Requires comparatively smaller pumps and heat exchanger for a given heat transfer rate Is a better neutron moderator as well Has a better heat transfer characteristics, and it can be pressurised to attain a high temperature All of these Requires comparatively smaller pumps and heat exchanger for a given heat transfer rate ANSWER DOWNLOAD EXAMIANS APP
Nuclear Power Engineering The half life period of a radioactive substance is best determined by counting the number of alpha particles emitted per second in a Geiger Muller counter from its known quantity. If the half life period of a radioactive substance is one month, then It will completely disintegrate in two months It will completely disintegrate in four months L/8th of it will remain intact at the end of four months 3/4th of it will disintegrate in two months It will completely disintegrate in two months It will completely disintegrate in four months L/8th of it will remain intact at the end of four months 3/4th of it will disintegrate in two months ANSWER DOWNLOAD EXAMIANS APP
Nuclear Power Engineering H₂ is a better coolant than CO₂, due to its relatively Lower neutron capture cross-section Higher specific heat Lower density Non-reactivity to uranium Lower neutron capture cross-section Higher specific heat Lower density Non-reactivity to uranium ANSWER DOWNLOAD EXAMIANS APP
