2. History of Remote Monitoring

3. Remote Monitoring Technology (RMT)

4. Global Use of RMT Technologies Global Growth • Today, the use of Remote Monitoring Technologies (RMT) of workers is growing globally. U.S. – Market Leader • The U.S. has lead the development and has demonstrated the benefits in reduction of individual dose utilizing worker telemetry to monitor Dose & Dose Rate. EPRI’s RMT Activities • EPRI (Electric Power Research institute) hosts an annual Remote Monitoring Working group of International attendees.

5. RMT Global Use- Benefits Wireless Technology in the Nuclear Industry • The development of wireless technology has spread throughout the world, and is only beginning to be utilized in KHNP, EDF plants and other nuclear sites around the world. Growing Need for RMT • Whether as a result of aging workforce or plant economics, the result is that plants have fewer personnel to monitor individual worker activities and need to rely on RMT to monitor various activities simultaneously. Benefits of RMT • Remote personnel can troubleshoot issues, advise on-site engineering and operators as how to remedy a problem quickly while improving performance.

6. KHNP has developed Remote Monitoring Video System (RMVS) for use within their nuclear stations. The use of RMVS has reduced the dose exposure received by workers. In Korea - RMT is Utilized

7. France & UK Markets - RMT • In France and associated EDF nuclear plants in UK utilize remote monitoring. • At recent ISOE meeting EDF’s presentation showed how EDF was integrating teledosimetry into their operations.

8. Use of Technology Expands

9. Remote Monitoring Technologies Countless Benefits of RMT • Greater worker protection • Minimizes potential of exposures • Provides the ability to respond quickly to control work activities in the case of emergency • Provides RP technicians with comprehensive monitoring and communication capabilities with RP workers to ensure worker and plant safety Increased Reliance/Use of RMT for Plant Workers by 2020, Including: • Biometrics • Position monitoring/location along with audio and visual interface with workers in radiation areas

10. In US, EPRI estimates RMT growth to be minimum of 10% per year with new applications and technologies. In US NPPs approx. 1/3 of all EPDs are transmitting. The Vision is to expand and include all workers on transmitting EPDs that include Biometrics, Positioning and location features EPD Telemetry Growth Rates

11. Growth in Biometrics is Expanding Growth of wireless technologies with Biometrics is expanding (Heat stress with older individuals is an issue) The introduction of Biometric monitoring of individuals along with dose and dose rate will become standard in workplace monitoring. Other emerging technologies is growing.

12. ALARA Add-On Devices • New ALARA devices • Links EPD to wrist display • Bluetooth connection • Allows easy Viewing • Alarm Notification

13. High Radiation Area Access Control

14. Future of RMT Flexibility is Key • The key to any RMT system in the future lies with the flexibility of its design and its impact on system infrastructure The Benefits are Clear • Customers see the value with RMT systems • Fleet RPM Manager feedback: • “ I would like to see all workers entering RCA areas to be constantly monitored to minimize worker exposure and daily challenges in the field.” Communication Between Electronic Devices • The ability of electronic devices (such as smart dosimeters) to integrate and communicate is key • As the industry expands its use, we cannot continue relying on the standard protocols of the past RMT – Growing Globally • The Growth of RMT Globally is expanding and projected @ min 10% /year based on discussions with EPRI.

15. Develop Detail Assessment & Site Plan • Remote Monitoring is present everywhere and people have become comfortable using it for many applications. • The advantages of wireless system are numerous, and challenges associated with RMT within plants need to be addressed. • Challenges with existing systems (i.e. Lost communication) can be minimized/avoided. • Development of site wireless assessment plan is essential for various wireless devices

16. What are the Challenges

17. Bandwidth, Data Rate, and Throughput

18. Packet Loss Descriptions • “Loss” is defined as packets that did not arrive and were dropped somewhere along the network path. • Packet loss can occur anywhere along the network path for a variety of reasons. Common reasons include: • „„ Layer-1 errors on the physical interfaces and cables along the path, such as a malfunctioning cable and optical interface. • „„ Mis-configured network interfaces along the path, such as Ethernet speed/duplex mismatches between devices. • „„ Bursts of packets exceeding the buffer (queue) limit or configurations on network interfaces along the path, such as Ethernet switches with insufficient queue depth or oversubscribed backplane architectures, or WAN router interfaces. • „„ A poor wireless network connection due to either distance to the access point or general network congestion.

19. Signal Throughput • Understanding Throughput Requirements • Knowing the data rate that a devices will send and receive at is critical for planning the network. • Result Packet Data Loss

20. Channel Allocation • When using > one access point or other access points in the area, identify the channels that will be utilized on each adjacent access point • Avoid using the same channel as an adjacent access point • For 2.4 GHz range - three channels (1,6 &11) do not overlap. This will minimize a kind of interference known as co-channel interference

21. Communication Systems –Interconnections During Event • As an industry, we are currently in the midst of a transformation • We must determine how we can utilize RMT within plant site boundaries AND off-site, in order to provide key information on: • Radiological Parameters • Environmental Conditions • Personnel Health.

22. Key Planning Concepts RMT Assessment • The overall RMT Assessment provides guidance and strengthens the plant’s approach to ensure key information (video/audio/data) are received to be analyzed Integrated Small Cell • The Integrated Small Cell becomes an important component of the spectrum management plan that combines dynamic spectrum access across spectra as diverse as data, video and audio Emerging Techniques • Using emerging techniques such as Distributed Mobility Management (DMM), these will provide efficient and high rate mobility solutions over localized regions, such as emergency planning zones around nuclear facilities

23. A Future with RMT… • The vision is for integrated solutions that addresses the issue at both the network and the customer user and management overview. • It starts with the key user devices, utilizing a smart connection manager that will fully automate spectrum access to the point where the users will no longer have to think about what cellular operator, what Wi-Fi SSID, what Bluetooth connection is needed • Users will simply start their apps- health monitoring. The smart connection manager will take this information, examine the available connectivity options together with access policies provided by the operator, and allocate the “right bandwidth” for the right application.

24. Key Points • Successful Site Plan • Must understand System limitations and minimize communications issues upfront • Design system for use vs ad-hoc • Expansion of monitoring capabilities of individuals • Integration of communications for onsite and offsite into one system
