Book Description
Several safety parameters are calculated for a large, fast, Na-cooled, oxide-fueled reactor. The Doppler coefficient is studied as regards its effect on the reactivity during a power excursion, and its dependence on the neutron spectrum, on the concentrations of U238, Pu 239, a nd Pu24°, on spatial temperature and power distributions, and on temperature. Other parameters studied include the Na temperature coefficient of reactivity, and the reactivity insertion caused by total Na loss; reactivity coefficients caused by thermal expansion of fuel and steel cladding; the excess operating reactivity; and the reactivity caused by a fuel slump. The effects of a Be reflector on neutron lifetimes are determined. The safety aspects are balanced against economic considerations. (T.F.H.).

Book Description
This volume contains the proceedings of the second in a series of annual topical conferences sponsored by Argonne National Laboratory and the U.S. Atomic Energy Commission on various specific aspects of fast reactor science and technology. The first conference, which was held in October 1963, was entitled "Breeding, Economics, and Safety in large Fast Power Reactors." The proceedings of that conference were issued as ANL-6702. Nor conference was held in 1964 because the Third International Geneva Conference on the Peaceful Uses of Atomic Energy had been scheduled for that year. In October 1959, a related conference entitled "The Physics of Breeding" was held at Argonne. The proceedings of that conference was issued as ANL-6122.

Book Description
Fast reactors are gradually attaining a very prominent place in the research and development programs of reactor research centers throughout the world. It is appropriate, therefore, that international conferences be held periodically to foster direct communication among fast reactor specialists. Subject-wise, this first conference was limited to the topics of breeding, economics, and safety of large fast reactors, with particular emphasis on the interrelation among them. Many other topics remain to be covered in future meetings.

Book Description
Calculations of the Doppler coefficient of large, ceramic-fueled fast reactors containing plutonium were made by means of the ELMOE program to provide accurate flux calculations. The temperature-dependent cross sections of P. Greebler et al., for U-238 and plutonium-239 were used. Doppler coefficients of the order of 105 intermediate temperature k/ C were obtained, in agreement with Greebler's results. Coefficients of carbide fueled reactors are about 0.7 of those of oxide-fueled reactors at the same fuel enrichment. Effective coarse-group elastic-removal cross sections for light elements are tabulated. It appears that, with tabulations of this sort as a guide, coarse-group sets of cross sections can be constructed to give adequate accuracy in calculations of Doppler coefficients without use of ELMOE.
