  Nuclear marine propulsion - Wikipedia, the free encyclopedia
It is known that during use the properties of nuclear fuel change, it is quite possible for fuel to crack and for fission gas bubbles to form.
A marine reactor was used to supply power (1.5 MWe) to a US Antarctic base for ten years to 1972, testing the feasibility of such air-portable units for remote locations.
Work on nuclear marine propulsion started in the 1940s, and the first test reactor started up in the United States in 1953.

A nuclear reactor is a device in which nuclearchain reactions are initiated, controlled, and sustained at a steady rate (as opposed to a nuclear explosion, where the chain reaction occurs in a split second).
Nuclear reactors are usedfor many purposes, but the most significant current uses are for the generation of electrical power and for the production ofplutonium for use in nuclear weapons.
Two U.S. nuclear submarines, the USS Scorpion and Thresher, have been lost at sea, though for reasonsnot related to their reactors, and their wrecks are situated such that the risk of nuclear pollution is considered low.

nuclear fuel is frequently expressed in terms of "full-power days," which is the number of 24-hour periods (days) a reactor is scheduled for operation at full power output for the generation of heat energy.
After fifty years of nuclear power the question of how to deal with this material remains fraught with safety concerns and technical problems, and one of the most important lines of criticism of the industry is based on the long-term risks and costs associated with dealing with the waste.

 Encyclopedia article on Nuclear reactor [EncycloZine]   (Site not responding. Last check: 2007-11-03)
In the vast majority of the world's nuclear power plants, heat energy generated by fissioning uranium fuel is collected in purified water and is carried away from the reactor's core either as steam in boiling water reactors or as superheated water in pressurized-water reactors.
Proponents of nuclear power maintain that nuclear energy is the only power source which explicitly factors the estimated cost of waste containment and plant decommissioning into its overall cost, and that the quoted cost of fossil fuel plants is deceptively low for this reason.
Nuclear power does have very useful additional advantages such as the production of radioisotopes which are used in medicine and food preservation, though the demand for these products can be satisfied by a relatively small number of plants.

 The Canberra Commission on the Elimination of Nuclear Weapons - Annex A
The nuclear weapon states are unlikely to accept inclusion of tritium in the proposed cut-off convention because of the changes to force structures this would require and consequent effect on deterrence.
A practical step would be for the nuclear weapon states and other states to commence a detailed study of how such a regime might operate, and what would be acceptable to the nuclear weapon states and to the international community at large.
As the nuclear powers go into their final countdown, there may be resistance to rapid elimination should the nuclear weapon states want a pause of some years to assure themselves (and others) that this elimination of bomb-building capabilities was both genuine and stable.

 Hyman G. Rickover - Wikipedia, the free encyclopedia
That he was willing to put his own life on the line during such nascent operations spoke loud and clear that he understood the importance of related success, and expected as much dedication from his own staff as well as the submarine's construction yard.
It could be argued that because of Rickover's singular focus on reactor operations, and direct line of communications with each nuclear submarine's captain, that this acted against the captains' warfighting abilities.
Creating a detail-focused pursuit of excellence to a degree that was previously unknown, he redirected the U.S. Navy’s ship propulsion, quality control, personnel selection, and training and education, and has had far-reaching effects on the defense establishment and the civilian nuclear energy field.
