environment.

Some Nuclear Facts*104 nuclear power plants supply about 20 percent of the electricity in the U.S*Nuclear materials are used inmedicinefordiagnosis 6 in medicine for diagnosis and cancer treatment*Nuclear materials are widely used in industry, such as in density gauges, flow measurement devices, radiography devices, and

irradiators The NRC Regulates*Nuclear reactors-commercial power reactors, research and test reactors, new reactor designs*Nuclear materials-nuclear reactor fuel, radioactive materials for medical, industrial, and academic use 7*Nuclear waste-transportation, storage and disposal of nuclear material and waste, decommissioning of nuclear facilities*Nuclear security-physical security of nuclear facilities and materials from sabotage or attacks What We Don't Do*Regulate nuclear weapons, military reactors, or space vehicle reactors 8*Own or operate nuclear power plants*Regulate some radioactive materials, such as X-rays and naturally

occurring radon How We Regulate*Establish rules and regulations*Issue licenses

• Provideoversightthroughinspection 9 Provide oversight through inspection , enforcement, and evaluation of operational

experience*Conduct research to provide support for regulatory decisions*Respond to events and emergencies Assurance of Plant Safety*Require "defense-in-depth"*Require long-term maintenance of equipment 10 equipment*Require continual training of operators

• Verify compliance with regulations What We Do -Nuclear Waste*The NRC regulates:-Storage of spent reactor fuel in fuel 11pools or dry storage

casks, and-Any national spent fuel storage site.

What We Do -Nuclear Security*NRC Requires:-Well-armed and well-trained security forces;-Surveillance and perimeterpatrols; 12 perimeter patrols;-State-of-the-art site access equipment and

controls;-Physical barriers and detection zones; and-Intrusion detection systems and alarm

stations.

NRC Performance Goals*Safety: Ensure adequate protection of public health and safety and the

environment 13*Security: Ensure adequate protection in the secure use and management of

• Residentbaselineinspections(e.g.,plantstatusreviews, 20 Resident baseline inspections (e.g., plant status reviews, equipment lineup "walkdowns," maintenance and testing verifications, operator qualification observations, refueling and forced outage activity specific inspections)*Regional specialist inspections (e.g., license renewal, plant modifications, security, radiation protection, emergency preparedness)

Resident Inspector Activities*Two full time Resident Inspectors assigned to Dresden that have unfettered access at the site*Monitor plant daily activities and issues (e.g., observe control room turnover and plan of the day tiiditit)21 mee ti ngs, rev iew every con diti on repor t)*Perform independent inspections based on a risk informed approach and knowledge of plant issues*Respond to the station during abnormal occurrences to observe and assess performance

• NRC Information Notice 2010-006, "Inadvertent Control Rod Withdrawal Event While Shutdown" Station Substantive Cross-Cutting Issue in Human Performance*22 overall findings*14 Green findings in 2009 involved a Human Performance Issue*5outofthe14findingssharedthecommonaspectofthe 25 5 out of the 14 findings shared the common aspect of the inadequate usage of human error prevention techniques (i.e.,

self and peer checking, pre-job briefs, proper documentation of activities). H.4(a) (ref. IMC 0310)*These findings affected multiple NRC cornerstone objectives

• The station has not made sufficient progress to date to address this issue Human Performance Issue Examples*FIN 2009002-005: Inadvertent actuation of the standby gas ventilation system*NCV 2009006-001: NRC identified a diesel driven fire pump discharge valve was out of position (i.e., ht)26 s h u t)*NCV 2009005-001: Operations personnel incorrectly placed tags *NCV 2009005-005: Spent fuel assembly moved to the wrong location in the spent fuel pool NRC Inspections Planned for 2010*Baseline annual ROP inspections*Baseline Biennial Problem Identification and Resolution team inspection
