2. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida 2 Why is spent fuel pool monitoring a concern?
3. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida An NRC task force has found that… "The lack of information on the conditions of the fuel in the Fukushima spent fuel pools … contributed to a poor understanding of possible radiation releases and to confusion about the need and priorities for support equipment. The Task Force therefore concludes that reliable information on the conditions in the spent fuel pool is essential to any effective response to a prolonged station blackout or other similarly challenging accident.” 3 Miller, C., Cubbage, A., Dorman, D., Grobe, J., Holahan, G., Sanfilippo, N., “Recommendations for Enhancing Reactor Safety in the 21st Century.” U.S. NRC (July 12, 2011).)
4. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida New NRC Level Monitoring Requirements (EA-12-051) 4
5. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida Current Practices • Narrow-range instrumentation • Limit switches • Check for departure of acceptable limits, nothing beyond this 5
6. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida Solution for Spent Fuel Pool Monitoring • Commercial, off-the-shelf equipment – Level sensors – Temperature Sensors – Radiation-hardened video equipment • Existing wireless transmission devices • Have already had success operating these devices in plants 6
7. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida System Overview 7
8. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida Challenges with Wireless Implementation • Electromagnetic compatibility (EMC) – Characterize the electromagnetic environment • Identify systems vulnerable to electromagnetic interference 8
9. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida Cyber-Security • Industry-standard wireless security protocols (WPA2 over 802.11b/g/n) • Meet or exceed guidelines established in IEEE 802.11i and NIST FIPS 140-2 9
10. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida Successes in Wireless • Arkansas Nuclear One • Comanche Peak • High Flux Isotope Reactor 10
11. 56th Annual ISA POWID Symposium, 3-5 June 2013, Orlando, Florida Conclusions • This system will greatly improve spent fuel pool monitoring, especially in the case of on-site power loss • Can provide for effective, targeted emergency response procedures • An increased level of safety for all 11
