NPTR HEAT TRANSFER ANALYSES
H. C. F. Ripfel and Q. L. Baird
The heat balance and physical design data for the Nuclear Proof Test
Reactor (NPTR) are linked together since the heat balance can be investigated
only with a sound basis of physical data. A rather important aspect is the
isotopic composition of the plutonium in the NPTR fuel. The a-decay heat
generated in the fuel has an impact on the safety of the facility. All
considerations assume that for ease of operation the NPTR should be maintained
at, or close to, room temperature and that design measures (e.g., void intro-
duction) should be such that they minimize the differences between FTR and
The following sections include: a consideration of the nuclear and
fission heat production(Section II); a physical description of the reference
and alternate core features, with special attention to the similarity to
the FTR and the necessary accommodations for heating and cooling (Section
III); a heat balance determination for the reference core including loss
of air coolant considerations (Section IV); a heat balance determination for
the molten sodium alternate (Section V); and heating and cooling considerations
for the fuel storage and handling area (Section VI). The results are summarized
in a conclusion (Section VII).
Cost and operational aspects of the molten sodium alternate feature are
discussed briefly in Appendix A. Appendix B is included to propose a high
temperature core zone (module).
