NE 127 – Codes, Standards, and Regulations Power Industry Regulations INSTRUCTOR: Chattanooga State CC
Topics of Discussion • Steps in the Production of Electricity • Overview of Basic Power Plant Operation • Regulation of the Nuclear Power Industry • NRC History, Responsibilities, and Structure
Basic Energy Processes • Natural electrical energy cannot be harnessed • It must be converted from another energy source • Four steps in the production of electrical energy
Basic Energy Processes Continued Step 1 • (Fossil) Conversion of chemical energy into thermal energy (heat) through the burning of a fossil fuel (coal, oil, or gas) • (Nuclear) Conversion of nuclear energy into thermal energy by fission Step 2 • Absorption of thermal energy by water (conversion of water into steam)
Basic Energy Processes Continued Step 3 • (Fossil and nuclear) Conversion of thermal energy from steam into mechanical energy as steam jet spins turbine blades • (Hydro) Conversion of potential energy of water into mechanical energy as water spins turbine blades Step 4 • Conversion of mechanical energy into electrical energy as rotation of turbine shaft rotates the shaft of the electrical generator, thereby producing electricity
Coal Plant Facts • In the 1920s coal plants had to burn 3 lbs of coal to produce 1 kW-hr of electricity • In the 1970s (time-frame for construction of many existing fossil plants), 1 lb of coal could produce 1 kW-hr of electricity due to improvements in plant efficiency • It takes ~11 lbs of air to burn 1 lb of coal • Slightly more air than required to ensure complete combustion • It takes ~1200 tons of water (300,000 gallons) to cool the exhaust steam from the burning of 1 ton of coal
Regulation of Nuclear Power Industry • Due to potential (however slight) for a catastrophic nuclear incident, the U.S. nuclear industry is highly regulated • Title 10 of the CFR governs Energy regulations • Chapter 1 contains parts 1-199 • NRC (Nuclear Regulatory Commission) is the regulating entity for those codes
History of the NRC • 1942 – Enrico Fermi, professor at University of Chicago created first sustained nuclear chain reaction under the Chicago Stadium • Atomic Energy Act of 1946 • Provided for the exclusive military use and control of nuclear energy • Atomic Energy Act of 1954 • Allowed for the commercial use of nuclear energy • Created the Atomic Energy Commission (AEC)
History of the NRC Continued • AEC Objectives • Promote the development of nuclear power • Regulate nuclear power • 1974 – Energy Reorganization Act • Abolished the AEC which was seen as controversial • Created two organizations to perform original AEC objectives • Energy Resources Development Administration (ERDA) • NRC
History of the NRC Continued • ERDA • Renamed Department of Energy (DOE) in 1975 • Governs the development of commercial applications of nuclear energy • NRC • Governs regulation of nuclear power
Three Mile Island, PA • Occurred on March 28, 1979 • Approximately half of reactor core melted • Generated fear of widespread radioactive contamination • No general evacuation was needed • Led to greater NRC emphasis on: • Operator training • “human factors” in plant performance • Emergency planning
More on NRC Responsibilities • Key licensing activities • Licensing the construction and operation of nuclear reactors and other nuclear facilities, and overseeing their decommissioning • Licensing all facets of nuclear material • Licensing low-level and high-level waste disposal sites • Licensing operators of nuclear power and nonpower test and research reactors
More on NRC Responsibilities • Other key responsibilities • Inspection of licensed facilities and activities • Research on light-water reactor safety and identification of potential safety issues • Development, implementation, and enforcement of NRC regulations • Investigation of nuclear incidents and allegations • Conducting of public hearings
NRC Organization • Headed by 5 Commissioners • Appointed by the President • Confirmed by the Senate for 5-year terms • One Commissioner designated as Chairman • Principal executive officer • Official NRC spokesperson (currently Gregory B. Jaczko) • Role of Commission • Formulate policies • Develop regulations governing nuclear material safety and security • Issue orders to licensees • Adjudicate legal matters
NRC Organization Continued *Note: NRC re-organized since the preparation of the red book • Inspector General (Hubert T. Bell) reports to Chairman • Executive Director for Operations (EDO) • Supervises and coordinates policy development of EDO staff and implements Commission policy directives • EDO Organization • Oversees 3 principle offices • Office for Reactor and Preparedness Programs • Office for Materials, Waste, Research, State, Tribal and Compliance Program • Office for Corporate Management
NRC Structure Continued • Office for Reactor and Preparedness Programs Oversees: • Regional Offices (Regions I – IV) • Office of New Reactors • Office of Nuclear Security and Incident Response • Office of Nuclear Reactor Regulation • Responsible for ensuring public health and safety through licensing and inspection activities • Includes licensing of operators; emergency preparedness; facility security (including fitness for duty); inspection of component suppliers; licensing and renewal of operating licenses
NRC Structure Continued • Office for Materials, Waste, Research, State, Tribal and Compliance Program Oversees: • Office of Nuclear Regulatory Research • Conducts own research and coordinates research with others (universities, those in the nuclear industry) • Studies risk • Office of Enforcement • Office of Nuclear Material Safety and Safeguards • Develops and implements NRC policy for regulation of activities involving use and handling of radioactive materials, including the fuel itself, its transportation, and waste • Office of Investigations • Office of Federal and State Materials and Environmental Management Programs
NRC Structure Continued • Office for Corporate Management Oversees: • Office of Information Services • Office of Administration • Computer Security Office
NRC Structure Continued • Direct Reports to the NRC Commission • Advisory Committee on Reactor Safeguards • Atomic Safety and Licensing Board Panel • Composed of administrative judges including lawyers, physicists, engineers, and environmental scientists • Conduct hearings for the Commission • Office of Commission Appellate Adjudication • Court of appeals
Next Time… • NRC Enforcement • CFRs for the Nuclear Power Industry
