Summary
This study evaluated tritium releases from Chinese nuclear power plants before 2009. Heavy water reactors showed higher airborne tritium releases compared to pressurized water reactors.
Area of Science:
- Environmental Science
- Nuclear Engineering
Background:
- Nuclear power plants generate radioactive effluents.
- Tritium is a key radionuclide of concern in nuclear effluents.
Purpose of the Study:
- To evaluate tritium releases and public doses from Chinese nuclear power plants before 2009.
- To compare tritium release pathways (airborne vs. liquid) across different reactor types.
Main Methods:
- Review of historical data on tritium releases from nuclear power plants in mainland China.
- Comparative analysis of tritium releases based on reactor technology (Pressurized Water Reactor vs. Heavy Water Reactor).
Main Results:
- Tritium releases from liquid pathways dominate for Pressurized Water Reactors.
- Airborne and liquid tritium releases are comparable for Heavy Water Reactors.
- Airborne tritium release from Heavy Water Reactors is significantly higher than from Pressurized Water Reactors.
Conclusions:
- Reactor type significantly influences tritium release pathways and magnitudes.
- Understanding these differences is crucial for environmental monitoring and dose assessment in nuclear power operations.

Nuclear Power
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

Nuclear Transmutation
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...
Nuclear Fission
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large number of different...
Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

Radioactivity and Nuclear Equations
Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The nucleus of an atom is composed of protons and, except for hydrogen, neutrons. The number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element.

Nuclear Stability
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.
