A preliminary study of a conceptual design of a fusion-fission hybrid system based on a mirror fusion reactor with a subcritical helium-cooled fission blanket
(Rensselaer Polytechnic Institute, Troy, NY, 1977-06)(5) In regards to safety, with the prospect of the potential release of fission products to the environment, the system will not achieve criticality as a result of an accidental insertion of positive reactivity such as ... -
A study of radiation-induced swelling in stainless steel weld metal
(Rensselaer Polytechnic Institute, Troy, NY, 1977-06)Changes in concentration of both major components and minor elements in an iron-chromium-nickel base alloy dramatically affect susceptibility to radiation-induced swelling. Substantial changes in composition occur in a ... -
An analytical approach to fast reactor fuel cycle analysis
(Rensselaer Polytechnic Institute, Troy, NY, 1976-05)A dramatic reduction in computing effort was achieved as a result of the coupling of the analytical solution of the depletion equations and the analytical prediction through correlation of the spectrum-averaged cross ... -
An improved water density feedback model for pressurized water reactors
