| Abstract: | Bhabha Atomic Research Centre
(BARC) is currently developing concepts of high temperature nuclear reactors
capable of supplying process heat at temperatures around 1000°C. These reactors would
provide energy to facilitate production of hydrogen by a suitable high efficiency
water splitting process. Currently a compact high temperature reactor is being
developed as a technology demonstrator for associated technologies. Design and
development has been also initiated for a 600 MWth Innovative High Temperature
Reactor. Carbon based materials have important applications in these reactors.
Nuclear fuel retaining elements in the form of fuel compacts and fuel pebbles,
as well as neutron moderators and reflectors use carbon based materials. These
materials are required to survive under extreme environmental conditions such
as neutron irradiation, high temperatures around 1000°C and corrosive
environment of liquid metal/salt based coolant. R & D issues involve design
methodology for carbon-based components, compatibility with other materials and
coolant, creep, and degradation under reactor conditions. Induced dimensional
changes, irradiation creep, and degradation of thermal and mechanical
properties are important factors to be considered in the design of these
components. The paper highlights design of these high temperature reactors in
general and their carbon based material related requirements in particular. |
