STUDY OF 40 MW PRESSURIZED WATER, BOILING WATER, AND ORGANIC MODERATED REACTORS FOR PRODUCTION OF PROCESS STEAM

The study efforts were toward the creation of a reactor design for each of the three types and the development of each concept to a point where the range of costs could be established. The studies presented have high burnup cores of low enrichment in an effort to minimize fuel costs. Of the three designs presented to deliver 1.25 x 10/sup 5/ lb/hr of 380 deg F steam at 196 psia the PWR core is the most favorable. (W.D.W.

ARGONNE HIGH-FLUX RESEARCH REACTOR-AHFR CONCEPTUAL DESIGN STUDY

This report presents a reactor design to meet the needs of the basic research program at Argonne National Laboratory. The program requires some irradiations in thermal neutron flux approaching 5 x 10/sup 15/n/ (cm/sup 2/ )(sec) and some beam experiments having over 10/sup 15/ n/(cm/sup 2/) available. Parametric studies indicate that the highest peak thermal flux per unit of reactor power can be obtained in an internal H/sub 2/ reflector having a radius of about 6 cm. Since the design effonts recognized total reactor cost as a mator parameter, an all H/sub 2/O-cooled system was adopted as most expedient. Further, the design and calculations effont was directed toward operating conditions which require little or no research effort. This latter point is a recognition both of the over-all cost plus a desire to meet the needs of research in the shortest possible time. (auth
