Nucleonic analyses have been performed for the Naval Research Laboratory's imploding-liner fusion reactor concept called LINUS. Mixtures of Pb and LiPb were used for the liquid metal liner (blanket), with blanket thickness, LiPb fraction, and Cd poisoning concentration being varied in scoping studies. Investigated responses were tritium breeding ratio, neutron leakage from the liquid liner to permanent reactor structure, and time-dependent nuclear heating of the liner and permanent structure. Tritium breeding ratio was as high as 1.8 for blankets sufficiently thick (approximately 1 m) to reduce leakage to the permanent structure to tolerable levels. Approximately 98.4% of the energy is deposited in the blanket within 10 ..mu..s, providing confidence that the heating of LINUS's blanket will occur while it is mechanically secure.
