Q. Select the incorrect statement about PWR.
  • (A) high primary circuit pressure requires a strong pressure vessel
  • (B) corrosion is less in pwr
  • (C) during fuel charging in pwr, the reactor has to be shut down at least for a month
  • (D) pwr results in uneven heating
💬 Discuss
✅ Correct Answer: (B) corrosion is less in pwr

Explanation: presence of high temperature and high pressure water, the corrosion is severe. this means use of stainless steel adds to further costing. when γ- radiations pass through the pressure vessel it results in uneven heating which induces thermal stresses on vessels.
