Slide 3 Mohammad Noshad (VLNComm)
Weaknesses of RF Networks
1.Vulnerable to a variety of cyber attacks such as man-in-the-middle attack (MITM), packet spoofing, packet injection, sniffing, unauthorized tapping and transfer
2.Electromagnetic interference (EMI) in the instrumentation and control system (I&C System) to perform safety function
3.Not reliable in a noisy environment

Ø Wi-Fi cause interference on RF devices in these environmentsØ Large number of users and robots need to be connected to networkØ Even wired networks are not completely practical due to the
moving robots or arms

qThere are three major issuesØ Electromagnetic compatibility (EMC) or interference (EMI) issuesØ Cyber securityØ Installation issues due to the type of the building structure
q In nuclear power plant control rooms, radio devices have been banned because of concerns about interference to the instrumentation and control equipment.q NO Wi-Fi or Bluetooth is permitted. q Wired network is costly and bulkyq A mesh network using of LED lights can reduce the pain

LC-based Wireless Sensor Networks in Nuclear Facilities
qIn 2009, the Nuclear Regulatory Commission (NRC) issued a cyber security rule requiring licensees to provide high assurance that critical systems and networks are adequately protected from cyber attacks [10 CFR 73.54].
q Although great effort has been spent to improve cyber security of RF wireless network technology such as Wi-Fi can still not be implemented everywhere in NPP.
