Which element will used for Ruppur Nuclear Power plant as fuel? (রূপপুর পারমাণবিক বিদ্যুৎ কেন্দ্রে জ্বালানি হিসেবে কোন উপাদান ব্যবহৃত হবে?)

সঠিক উত্তর: Uranium

Consider the following statements.
1. The chain reaction process is used in nuclear bombs to release a vast amount of energy, but in nuclear reactors, there is no chain reaction.
2. In a nuclear reactor, the reaction is controlled, while in nuclear bombs, the reaction is uncontrolled.
3. In a nuclear reactor, all operating reactors are 'critical', while there is no question of 'critically' in case of a nuclear bomb.
4. Nuclear reactors do not use moderators, while nuclear bombs use them.
Which of the above statements about operational principles of a nuclear reactor and a nuclear bomb is/are correct?

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:

With reference to 'fuel cells' in which hydrogen rich fuel and oxygen are used to generate electricity. Consider the following statements.
1. If pure hydrogen is used as a fuel, the fuel cell emits heat and water as by products.
2. Fuel cells can be used for powering buildings and not for small devices like laptop, computers.
3. Fuel cells produce electricity in the form of Alternating Current (AC).
Which of the statements given above is/are correct?
