I&C – a Nuclear Power Plant’s Central Nervous System Through its constituent elements, such as equipment, modules, sensors, transmitters, motors, valves and others, the I&C system senses plant parameters, monitors performance, integrates information, and makes automatic adjustments to the NPP’s operations as necessary.
How are nuclear facilities protected?
Security measures include: physical barriers, electronic detection and assessment systems, and illuminated detection zones. electronic surveillance and physical patrols of the plant perimeter and interior structures. bullet-resisting, protected positions throughout the plant.
Who provides security for nuclear plants?
The U.S. Nuclear Regulatory Commission (NRC)
The U.S. Nuclear Regulatory Commission (NRC) regulates both safety and security at nuclear power plants. After 9/11, these sites were required to add multiple layers of protection, with the cores of reactors (where the fuel is located) the most highly defended areas.
What are I&C systems?
The Instrumentation and Controls (I&C) systems of a nuclear power plant (NPP) function as the “nervous system” of the plant. New reactor designs have highly integrated digital systems, and the existing fleet of operating reactors are implementing digital upgrades to address obsolescence issues with analog equipment.
What is nuclear Control?
To maintain a sustained controlled nuclear reaction, for every 2 or 3 neutrons released, only one must be allowed to strike another uranium nucleus. Most reactors are controlled by means of control rods that are made of a strongly neutron-absorbent material such as boron or cadmium. …
What are control rods made of?
Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium. Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons without themselves fissioning.
Why is nuclear security important to facilities?
Nuclear security relates to the prevention and detection of, and response to, theft, sabotage, unauthorised access and illegal transfer or other malicious acts involving nuclear material and other radioactive substances and their associated facilities.
How can we prevent nuclear plant accidents?
Five steps to prevent another Fukushima
- Stabilize the electricity supply system.
- Store spent fuel in dry casks.
- Install filtered vent systems.
- Prevent sabotage at nuclear facilities.
- Ratify a treaty to prohibit military attacks.
How can we control nuclear accidents?
What are the security measures taken in storing nuclear power plants?
Security enhancements put in place since 2001 for nuclear power plants include:
- Upgraded physical security plans.
- Enhanced security officer training.
- Increased security patrols.
- Additional physical barriers.
- Greater stand-off distances for vehicle checks.
- More restrictive site access controls.
What is electrical and I&C?
GSE’s Electrical and Instrumentation & Control (I&C) Engineering team focuses on power plant electrical, instrumentation and control systems. We work in close coordination with supporting and supported engineering disciplines. …

How do you control access to a nuclear power plant?
Controlling Nuclear Power Plant Access. The industry’s authorization program for unescorted access to a nuclear power plant includes an FBI criminal history review; psychological assessments; work, education and credit history reviews; fitness for duty reviews; and pre-access and random drug and alcohol tests.
How to develop access control procedures for a federal facility?
Developing Access Control Procedures When developing access control procedures for a federal facility, the facility should match security procedures with the threat against the tenant agencies. 1 The Facility Security Committee makes most determinations for multi-tenant facilities.
What is the owner controlled area of a nuclear reactor?
The large outer perimeter, called the “owner-controlled area,” is far enough from the reactor that only minimal security is needed. Other than signs, the security measures in place for the owner-controlled area are not always visible to the public.
What is the “vital area” in nuclear power plants?
The innermost circle is called the “vital area.” It contains the reactor and associated safety systems, the control room, the used fuel pool, and the main security alarm stations. Access to the vital area is limited and protected by locked and alarmed security doors. Every nuclear power plant has an NRC-approved cybersecurity plan.
