Regarding nuclear reactor I need some clarifiications;
1. During fisssioin of U-235 it is said that the temperature raises to several million degree celcius (in uncontrolled chain reation). But what will be temperature produced when a controlled chain reaction takes place inside a nuclear reactor? In the case of a coolant such as a pressurised heavy water, its boiling point is only around 300 degree celcicus. Even if the temperature inside a reactors will not be to such an extent of several million degrees as in the case of atom bomb, definitely it will touch a few thousands in the reactor. Then how is that the water remains without boiling in the primary loop and conducts heat to the heat exchanger? What wiil be the temperature range inside a reactor? How is achieved?
2. What is the exact critical mass and size for U-235? Different values are given in different textbooks?
