(a) 2

(b) 3

(c) 4

(d) 5

This question was posed to me in a national level competition.

This intriguing question originated from Types of Nuclear Reactor & Nuclear Waste in portion Nuclear Power Plant of Energy Engineering

Answer 1

The correct option is (b) 3

Explanation: There are three different types of BWR cycles commonly used:

 Single cycle internal circulation: This system uses internal recirculation system to generate power ranging from 50- 100 MW.

 Single cycle forced circulation: This type uses a forced circulation system using a circulation system using a circulating pump. The heat in the reactor is used to generate steam.

 Dual cycle forced circulation: this arrangement has two cycles, steam cycle and gas cycle.
