Introduction

Terminology is the basis for standardization in a field. In order to standardize and unify a large number of terminology in the field of nuclear science and technology and improve communication To ensure accuracy and efficiency, our country has formulated and released GB/T 4960 "Nuclear Science and Technology Terminology", which is planned to consist of 9 parts.

---Part 1. Nuclear physics and nuclear chemistry. The purpose is to define terms and definitions in nuclear physics and nuclear chemistry.

---Part 2. Fission Reactor. The purpose is to define the terminology and safety aspects of nuclear fission reactor design, commissioning and operation. definition.

---Part 3. Nuclear fuel and nuclear fuel cycle. The purpose is to define uranium mining, uranium conversion, fuel element design and manufacturing, etc. Terms and Definitions.

---Radionuclides. The purpose is to define the terms and definitions of radionuclides and their applications in agriculture, industry, medicine, etc.

---Radiation protection and radiation source safety. The purpose is to define terms and definitions in radiation protection, radiation source safety, etc.

---Part 6. Nuclear instrumentation. The purpose is to define terms and definitions for various types of instrumentation used in the nuclear industry.

---Part 7. Nuclear material control and nuclear safeguards. The purpose is to define terms and definitions in the context of nuclear material control.

---Part 8. Radioactive waste management. The purpose is to define the terminology and definition.

---Part 9. Magnetic confinement nuclear fusion. The purpose is to define terms and definitions in the field of magnetic confinement fusion.

This document standardizes the terminology in the field of nuclear material control and nuclear safeguards in my country, plays a unifying and coordinating role, and facilitates the relative control of nuclear materials in my country.

The exchange of relevant work has played an important guiding role in my country's nuclear material control work. However, with the development of nuclear science and technology, many new processes, new methods, new technologies, new understandings and new needs since the promulgation of the Nuclear Safety Law of the People's Republic of China, the original standards cannot fully meet the current requirements.

Definition of pre-nuclear science. In order to meet current needs, reduce synonymous and synonymous definitions of nuclear material control terms and avoid nuclear material control terms ambiguities and misunderstandings, this document is specially revised. The revision of this document aims to meet the needs of my country's nuclear material control work and achieve unified standards for my country's nuclear materials control work.

Nuclear material control terms and definitions are coordinated and unified with international terminology to achieve the purpose of international integration and make it more scientific, reasonable and effective.

1 Scope
