ABSTRACT
The Heavy Water Components Test Reactor (HWCTR) was shut
down most of May and June 1964 for repair of equipment. A
D20 leak in one of the steam generators was repaired, and
shaft seals were replaced on the main D20 pumps. A cladding
failure occurred in an assembly of compacted U02 fuel tubes
at extremely low exposure because of inadequate sealing of
an end plug during fabrication of the tubes.
A technique was developed for the calculation of multi-
group one-dimensional neutron density distributions by the
use of heterogeneous one-group diffusion calculations.
Additional U02 fuel tubes for HWCTR irradiation tests
were fabricated, and fabrication development was started on
a set of U02 driver fuel tubes for the HWCTR.
An engineering study of large D20-moderated power
reactors indicated that reactors designed for liquid D20 or
organic cooling are technically feasible in capacities at
least as large as 8300 MW (thermal).-2-
