Region II Organization William Travers Regional Administrator Victor McCree Deputy Regional Administrator Charles Casto Director Division of Reactor Projects Harold Christensen Deputy Director Joseph Shea Director Division of Reactor Safety Kriss Kennedy Deputy Director Jim Moorman Branch Chief Regional Specialists Catawba Nuclear Station Andrew Sabisch; SRI Gordon Williams, RI Lee Harmon, OA Project Engineer Curt Rapp, SPE
NRC Performance Goals Ensure protection of the public health and safety and the environment Ensure the secure use and management of radioactive materials PRIMARY GOALS OTHER GOALS
- Ensure openness in NRC regulatory process
- Ensure that NRC actions are effective, efficient, realistic, and timely
- Ensure excellence in NRC management to carry out the NRCs strategic objective
Reactor Oversight Process The NRC monitors plant performance The NRC monitors plant performance in three major areas:
in three major areas:
Reactor Safety Reactor Safety (avoiding accidents or (avoiding accidents or transient & reducing their consequences if transient & reducing their consequences if they occur) they occur)
Radiation Safety Radiation Safety (both plant workers & the (both plant workers & the public during routine operations) public during routine operations)
Security Security (protection of the plant against (protection of the plant against sabotage or other security threats).....
sabotage or other security threats).....
Major changes in the post Major changes in the post--9/11 environment 9/11 environment
Reactor Oversight Process
Reactor Oversight Process The ROP includes two separate sources of The ROP includes two separate sources of information:
information:
- Inspections conducted by NRC personnel Inspections conducted by NRC personnel
- Performance Indicators developed from data Performance Indicators developed from data provided by licensees provided by licensees Inspectors can be Site Inspectors can be Site--based or Region based or Region--
based based Together they provide a composite picture Together they provide a composite picture of how the plant is being operated of how the plant is being operated
