What We Regulate Reactors Materials Waste
What We Dont Regulate Military Radon X-Rays
Some Nuclear Facts
- 100 nuclear power plants supply about 20 percent of the electricity in the U.S.
- Nuclear materials are used 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.

NRC Annual Assessment Summary Dresden Nuclear Power Station 2015 Exelon operated the station safely and in a manner that preserved the public health and safety and protected the environment.
Dresden Unit 2 was in the Regulatory Response Column of the NRCs Action Matrix at the start of 2015 in first quarter of 2015 due to a White performance indicator for greater than 3 scrams per 7000 operating hours and remained there until August 7, 2015.
for the last three quarters of 2015 due to a White finding on the inoperability of a Unit 2 Electromatic Relief Valve and remained there until the end of the first quarter of 2016 Dresden Unit 3 was in the Regulatory Response Column for the fours quarter of 2015 due to a White finding on the inoperability of a Unit 3 Electromatic Relief Valve and remained there until December 2, 2015 No Substantive Cross-Cutting Issues were identified 14 14
NRC Inspection Activities Dresden Nuclear Power Station 2015 5307 total hours expended by NRC on Reactor Oversight Process activities 2360 inspector hours of direct inspection activity 733 inspector hours reviewing and observing plant operating status 1291 inspector hours of preparation for and documentation of inspection activities 923 hours0.0107 days <br />0.256 hours <br />0.00153 weeks <br />3.512015e-4 months <br /> for other Reactor Oversight Process elements (e.g., assessments and communications) 15
NRC Inspection Activities Dresden Nuclear Power Station 2015 2 resident inspectors on site - residents produced four quarterly inspection reports and walked through the plant daily 26 other inspectors participated in various inspections 4 major inspections Two Supplemental Inspections for Regulatory Response Column entry Initial Reactor Operator License Examinations Modifications/10 CFR 50.59 Inspection 16
Significance Threshold Performance Indicators Green Baseline Inspection White Requires additional NRC oversight Yellow Requires more NRC oversight Red Requires most NRC oversight Inspection Findings Green Very low safety issue White Low to moderate safety issue Yellow Substantial safety issue Red High safety issue 17
Dresden PIs and Findings January 1 through December 31, 2015 Green Performance Indicators with One White in first quarter of 2015 11 Green/Severity Level IV Inspection Findings 1 White Inspection Finding associated with the Mitigating Systems Cornerstone 18
Safety Significant Findings Dresden Nuclear Power Station NRC Identified one Unit 3 White finding in Fourth Quarter of 2014 which carried over to 2015 NRC Identified one Unit 2 White finding in Second Quarter of 2015 Both Findings Involved one of four Electromatic Relief Valves on each Units Main Steam Lines Valves are designed to rapidly reduce reactor vessel pressure if needed Licensee failed to ensure continued operability of valve with increased steam flows after implementing an approved power uprate
NRC Inspection Findings Some Examples of Green Findings Dresden Nuclear Power Station Failure to prevent foreign material (teflon tape) from degrading a relay in the starting circuit of a emergency diesel generator resulting in diesel generator inoperability Failure to perform Ultimate Heat Sink surveys in accordance with the Quality Assurance Program Failure to ensure procedure revisions did not result in conditions that could cause the Isolation Condenser to be outside of its design conditions 20

- Site Audit was performed in August 2015
- Site Safety Evaluation scheduled to be issued after the NRC receives the site compliance letter
- Regional inspection of MS inspection (TI 191, Rev 1) will be performed after Safety Evaluation issued 22
Hardened Vent Order
- Requires that the hardened vents be capable of operating under severe accident conditions
- Licensee Combined Phase 1/Phase 2 Plan submitted in December 2015
- Site Audit Reports will be developed after Sites come into compliance with each Phase of the Order
- Completion expected in 2017 to 2018
- Site inspection will follow 23
Dresden Fukushima Flooding Response Status
- Flooding Hazard Reevaluations
- Reevaluate Hazards using present-Day information
- Licensee Flooding Evaluation was submitted in 2013 with followup answers to questions in 2014
