TECHNICAL PARTS OF CHAPTER 1 OF TITLE 10
The parts governing the licensing and operation of nuclear power plants, together with a short summary (not as precise as the regulation), are described below for easy reference. Part 52 is not directly applicable to the operating reactors. However, it has been summarized here because Chapter 9 of the book discusses the regulation in context with advanced reactors, where Part 52 is applicable.
Requirements of Parts 20 and 21
Part 20 — Standards for Protection Against Radiation
The regulations in this part establish standards for protection against ionizing radiation resulting from activities conducted under licenses issued by the Nuclear Regulatory Commission. These regulations are issued under the Atomic Energy Act of 1954 and the Energy Reorganization Act of 1974.
Part 21 — Reporting of Defects and Non-Compliance
This part applies to any individual director or responsible officer of a firm constructing, owning, operating, or supplying the components of any facility or activity which is licensed or otherwise regulated pursuant to the Atomic Energy Act of 1954 (as amended) or the Energy Reorganization Act of 1974. If such an individual obtains information indicating: (a) that the facility, activity, or basic component supplied to such facility or activity fails to comply with the Atomic Energy Act of 1954, as amended, or any applicable rule, regulation, order, or license of the Commission relating to substantial safety hazards or (b) that the facility, activity, or basic component supplied to such facility or activity contains defects, which could create a substantial safety hazard, to immediately notify the Commission of such failure. Under this regulation, the vendors of the structures, systems, and components, as well as the designers of the nuclear plant’s SSCs are required to report to the NRC potential defects in the hardware and/or calculations that would have long-term effects on the safety of the plants.
