1 Introduction
1.1 Purpose
This guide provides guidance for the units responsible for design, construction, operation and decommissioning of nuclear facilities to carry out radioactive waste minimization (hereinafter referred to as “waste minimization”), and also provides reference for regulatory authorities to conduct nuclear safety review, supervision and management.
Appendixes I, II and III have the equal force as the text.
Annexes A, B and C are informative.
1.2 Scope
This guide is mainly applicable to the waste minimization in the design, construction, operation and decommissioning stages of PWR nuclear power plants and it may also be referenced by nuclear facilities such as other reactor nuclear power plants, nuclear fuel cycle facilities and research reactors.
2 Objectives and principles
2.1 Overall objectives
In the procedure of design, construction, operation and decommissioning of nuclear facilities, measures such as source control, recycling and reuse, clearance, optimized waste treatment and strengthened management are taken and cost and benefit analysis is conducted to enable the final amount of radioactive solid waste (volume and activity) as low as reasonably possible.
2.2 Basic principles
The waste minimization of nuclear facilities shall be based on the premise of ensuring safety, with waste disposal as the core, and follow the principles of giving priority to source control, whole procedure management, all-member responsibility and continuous optimization for the purpose of realizing waste minimization through technical and management measures.
2.3 Target value of waste minimization
The annual amount of radioactive solid waste from nuclear facilities shall be as low as reasonably possible by adopting practical design and management measures and comparing with international best practices.
Annex A specifies requirements for annual amount of single-unit waste packages from PWR nuclear power plants in major nuclear energy countries in the world and waste packages from newly built PWR nuclear power units specified in nuclear power plant user requirement documents in US and Europe.
3 Waste minimization in design and construction stages
3.1 General requirements
3.1.1 Appropriate design measures shall be taken to reduce the generation of radioactive waste from the source and keep the amount of radioactive waste as low as reasonably possible.
