| Consider the following statements with reference to the hydrogen fuel |
| 1. Bhabha Atomic Research Centre (BARC) Trombay is on the brink of developing a Compact High Temperature Reactor (CHTR) would to produce Hydrogen fuel. |
| 2. The CHTR would use Thorium Uranium 233. |
| 3. It would break water into molecules of hydrogen and oxygen. Which of the statements given above is/are correct? |
A) 1, 2 and 3
B) 1 and 2
C) 2 and 3
D) Only 1
Correct Answer: A
Solution :
[a] High temperature nuclear reactors are capable of supplying process heat at temperatures around \[1000{}^\circ C\]. 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 \[1000{}^\circ C\] 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.
