I will have to do more research on this topic. The largest experience in operating nuclear power plants has been in nuclear naval propulsion, particularly aircraft carriers and submarines.This accumulated experience may become the basis of a proposed new generation of compact-sized nuclear power plants designs.The mission for nuclear powered submarines is being redefined in terms of signal intelligence gathering and special … Question2) Explain the disease symptoms caused by Ustilago and its control. Current space missions use fuel cells, nuclear batteries or solar power. Conventional nuclear power stations and the generating plants on nuclear submarines and ships use the technique to make electricity. Very Explain regarding the presence of phosphorous in waste water and its removal. However, most of these studies have been concerned with the type of bacterial contaminants found in natural systems and thoses encountered in closed ecological systems designed for use in space craft and nuclear submarines (3, 4, 6, 8).
