Nuclear power reactors are operated at low temperatures and consequently with lower efficiency because:

نیوکلیئر پاور ری ایکٹر کم درجہ حرارت اور اس کے نتیجے میں کم کارکردگی کے ساتھ چلتے ہیں کیونکہ

High pressure inside the reactor reduces the temperature

Uranium is difficult to heat

The walls of nuclear reactors cannot withstand high temperature

none of these

Explanation

Answer:

Nuclear power reactors are operated at low temperatures and consequently with lower efficiency because The walls of nuclear reactors cannot withstand high temperature
