Witness software, showing detection and visualisation of small deer

ConclusionPower stations are national assets and their security is of strategic importance. The capabilities of AdvanceGuard are ideally suited for this specific application. The system has a greater capability than other security technologies, even in the poorest weather, lighting and environmental conditions. Designed specifically to help prevent access into sensitive or high-security areas, AdvanceGuard can change detection areas for different times of day, and in so doing increases the coverage and monitoring at, or even beyond, the perimeter. This option is available for both day and night time surveillance.

With unrivalled performance in minimising false alarm rates, reliability can be assured and on-site guarding can be deployed to patrol and control any incident efficiently and effectively.

The system can be configured to provide detection well before a breach into a critical zone occurs. And because the perimeter of a detection area is effectively predefined within the system’s software, it need not be a fixed line, making AdvanceGuard the ideal security partner in protecting complex real estate configurations, such as power stations.

Reducing the requirement for physical boundaries, AdvanceGuard’s superior detection range minimises the requirement for infrastructure, reducing maintenance costs, power consumption and number of required cameras. The economic and environmental benefits of this are clear.

Further ApplicationsAs well as those listed in this application note. The possibilities surrounding Navtech’s AdvanceGuard solution are endless.

By constantly innovating and building upon 15 years of existing knowledge and experience, Navtech are able to provide tailored solutions for a multitude of challenges.

Tightening Security

Perimeter SurveillanceAdvanceGuard perimeter surveillance is the first key barrier to prevent intrusion. Using a high frequency radar to scan the area, AdvanceGuard is able to detect any target, such as people or vehicles over a wide area. Advanced tracking algorithms follow intruders’ movements and alert control room operators to any potential threats by locating them on an onscreen site map, as well as automatically guiding CCTV cameras to track the intruders’ precise location. Security personnel have complete situational awareness and are equipped with vital information such as direction, speed and type of intruder, allowing them to react in the most appropriate manner.

Water Facing Applications and Cooling Facility ProtectionThe very nature of nuclear power tends to require proximity to expanses of open water. Often the most vulnerable area of a nuclear site is its cooling facility. By cutting off the cold water supply, malicious attackers can cause the plant to stop functioning for extended periods of time. Water pipes, valves and processing facilities are, therefore, key areas that must be protected. AdvanceGuard can cover the most vulnerable areas where these pipes come ashore.

In addition, any intruders approaching the perimeter fence via this vulnerable coastal corridor of both land and water will be detected.

Roof Top SurveillanceAs with the sea, the air is also a difficult area that high security facilities have increasingly been looking to defend. With the use of Unmanned Autonomous Vehicles (UAVs), often referred to as drones, surveillance technology has needed to adapt to this new vulnerability. Navtech have, therefore, provided the innovative solution of installing radar sensors on top of the site’s buildings.

At this elevated height, sensors are able to detect and track any UAVs within or approaching the facility, and provide early warning to security staff.

Scanning Radar SolutionNavtech’s experienced project delivery team carefully evaluate each site and establish the most efficient and effective installation necessary for total site security. In a typical installation a variety of AdvancedGuard AGS sensors are used. These are placed on perimeter fences, site buildings, coastal corridors and the Nuclear Island for absolute coverage. Each AGS unit provides a compact, high performance, scanning radar sensor that scans 360° every second and is capable of detecting vehicles, humans and animals in all weather conditions.

Housed in a lightweight, IP67-compliant enclosure, the AGS series features an industry standard interface for easy setup and is used as part of a multi-radar solution. The radar units’ wide-area surveillance capabilities are interfaced with Navtech Radar’s sophisticated physical security information management (PSIM) system called WitnessTM.

Witness manages all system functions; from analysing movement to creating target ‘tracks’ and controlling cameras to follow them, to handling the complex algorithms in the security rule engine which analyses target behaviour, assigns threat levels and allow security staff to define alarm zones and the rules that trigger them. In this respect, radar is much like video and other sensors in that it provides as much information as it can but the full realisation of its functionality is down to the sophistication of the real time processing software.

Nuclear IslandThe area that must be protected at all costs is the nuclear reactor within “The Island”. As well as high level security at every possible point of entry, the Nuclear Island itself can also be protected by AdvanceGuard. Whilst monitoring inside the Island to ensure an entirely sterile environment, the radar sensor is able to simultaneously monitor movement around the Island, detecting, tracking and forewarning against any unauthorised movement towards the reactor.

The Witness software system harnesses the power of Navtech’s security radar, to provide a fully integrated solution for a wide range of security applications. It draws on over 10 years’ experience of working with ground surveillance radar. This unique knowledge has enabled Navtech to implement critical features that enhance the capability of security radar and overcome weaknesses associated with more traditional security solutions, such as excessive nuisance or false alarms.

Witness includes an intuitive on-screen security interface which allows users to draw or revise alarm zones and their associated rules. At the simplest level, it can replace physical barriers using ‘virtual fences or access points’ which alarm when objects enter them, travel in the wrong direction within them, or pass through out of hours. Witness allows the setting of rules to do this automatically.

With virtually no limit to the complexity of the rules that can be applied in Witness, a level of pseudo-intelligent monitoring can be introduced that closely mimics a human observer. By comparison, while video analytics may appear to be able to do many of the same things, in practice it has limited coverage, does not have accurate speed, direction and location information, and is affected by environmental conditions.

As of July 2015, 438 nuclear reactors provide electricity generation across 30 countries worldwide, with 67 new nuclear plants currently under construction. Producing 10.9 percent of the world’s electricity in 2012 , nuclear power plants are a vital part of global infrastructure and power supply.

These nuclear sites are vulnerable to a wide range of threats and are under increasing pressure to defend themselves against a variety of possible security breaches. Ranging from the simple threat of theft or malicious entry, to industry specific attacks from terrorist and protest groups, to extreme acts of state terrorism. In this technologically advanced age, intruders’ methods are evolving and adapting to traditional methods of security, driving governments and power plants alike to focus their energies on investing in security systems of the highest calibre.

Having enabled high level security systems worldwide for an extensive range of applications, Navtech is well experienced in providing unparalleled solutions for a variety of problems. Drawing on over 15 years’ experience working with 360° scanning radar, Navtech have been able to provide sophisticated security systems to several Nuclear Power Plants.

Radar ApplicationsWith a maximum detection range of 1600 metres, Navtech’s 360° scanning radar sensors hold a number of advantages over traditional security surveillance technologies. Unlike standalone CCTV cameras, radar is unaffected by external conditions such as high wind, fog, rain and snow. Navtech’s AdvanceGuard™ solution has been selected for its ability to provide unrivalled threat detection in all weather conditions. Essential in mission-critical applications, AdvanceGuard provides high reliability where alternative solutions could not. "Palo Verde Nuclear Generating Station" by Cuhlik
