| Abstract: | Total/occluded or residual gas
content of sintered nuclear fuel pellets is an important specification. The
specification of the gas content depends on the nature of the fuel and type of
the reactor. The total gas content and its composition were determined employing
hot vacuum extraction followed by quadrupole mass spectromety. Detailed
investigations carried out on the determination of total gas in various types
of nuclear fuels used in different types of reactors are reported in this
paper. Oxide pellet is heated at 1650°C for 15 min while carbide
pellet is heated at 1000°C for 30 min for the determination of total gas content.
The overall measurement error is ± 5% and the detection limit is 0.005 cc. The main
constituent of the gas is hydrogen (> 95%) in all the types of fuel pellets. |
