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 heatingThis question was posed to me during an interview.Enquiry is from Types of Nuclear Reactor & Nuclear Waste topic in portion Nuclear Power Plant of Energy Engineering

Answer»

Correct option is (b) Corrosion is less in PWR

Easy 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.
