Which type of fuel is removed from the reactor core after reaching end of core life service?

Which type of fuel is removed from the reactor core after reaching end of core life service? Correct Answer Spent fuel

Spent fuel is the unprocessed fuel that is removed from the reactor core after reaching end of core life service. It is removed and then stored for 3 to 4 months under water in the plant site to give time for the most intense radioactive isotopes to decay.

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
