Pingnan Baisha Nuclear Power Station, also known as Guangxi Guidong Nuclear Power Station, was signed by China Power Investment Group and Pingnan County Government on August 3, 2009, and the nuclear power was initially determined. A nuclear energy is the energy released by nuclear fission or nuclear fusion, so A is correct; But it does not conform to the meaning of the problem;

B, the current nuclear power plant uses nuclear energy through fission reaction, so B is wrong; Meet the meaning of the question

C, nuclear energy is the use of radioactive nuclear fuel to release energy, and the reserves of these substances on the earth are certain, so they belong to non-renewable energy and primary energy, so C is correct, but it does not meet the meaning of the question;

D, the chain reaction in the nuclear reactor can be controlled, so D is correct, but it doesn't meet the question.

So choose B.
