Which of the following types of nuclear reactors is most prone to radioactive hazards ?
Correct answer: C. Boiling water reactor
- A. Pressurised water reactor
- B. Gas cooled reactor
- C. Boiling water reactor
- D. Molten sodium cooled reactor
Explanation
A boiling water reactor is more prone to radioactive hazards outside the reactor vessel because its primary coolant boils and the resulting steam passes directly to the turbine. In pressurised-water systems, the radioactive primary loop is separated from the steam loop.
