Nuclear power plants call for 24/7 continuous monitoring

Incidents in nuclear power plants around the world have continued to demonstrate the vulnerability of safety systems to fire and its effects. The potential danger from an accident at a nuclear power plant is exposure to radiation to the people in the vicinity of the plume from the cloud and particles deposited on the ground, inhalation of radioactive materials and ingestion of radioactive materials. It is for this reason that the safety demands of the Atomic Energy Authority must be met.

The Dangers Presented by Fire

The International Atomic Energy Authority state clearly in the Fire Safety in the Operation of Nuclear Power Plants standards that the effects of a single failure in fire safety systems, such a system not performing its required function, can be detrimental.

With fires at nuclear power plants still occurring, such as the 2017 power plant explosion at Flamanville, deemed “very serious” by industry experts, the call for advanced technology is of most importance. A significant technical issue led to a blast in the turbine hall in the unit, although there was no radioactive leak, a thorough investigation is being conducted into the concerning event.

What are Gaseous Extinguishing Systems?

Gaseous extinguishing systems protect urgently important infrastructure against special hazards, fundamental for the safeguarding of critical facilities. Gaseous extinguishing systems are highly pressurised: approximately 29-48Bars of pressure for CO2, and up to 300 Bars for Inergen and Nitrogen, higher than a standard cup of water which is at 1bar. The risk of the agent contents leaking and discharging is widely accepted by the industry and this is shown in the regulations that demand their upkeep.

Because it is accepted that gaseous extinguishing systems are dynamic and not passive or static.

The neglect of continuous monitoring - of the fundamental protection provided by the gaseous extinguishing systems - is to the peril of the lives of occupants of the premises and at the risk of crippling financial and reputational loss to the facility comprising the critical infrastructure.

Safesite Solutions: the future is 24/7 constant monitoring

Coltraco have developed the Permalevel® Multiplex, a fixed fire suppression monitoring device, designed for permanent contents verification. The Permalevel®  Multiplex    is  designed  to  ensure  that fire  suppression  systems  are  always  fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire at a nuclear power plant. With guaranteed systems operations, adaptability for purpose, 24/7 remote access to the systems status, an interruptible power supply and remote real-time monitoring, the Permalevel® offers unbeatable efficiency. The likes of the Atomic Energy Authority asked Coltraco Ultrasonics to tailor make them a solution to constantly monitor a special application using the Permalevel® Single Point for over 10 years.

The Portascanner® 520 is the most mathematically accurate device available providing precise data concerning leak locations and aperture. It is unrivalled in its precision, non-invasive methodology and ease of use. It is perfectly positioned to work alongside Door Fan testing in order to meet the total requirements for fire safety regulations and ensure the continuous fire protection of rooms using Clean Agent Fire Suppression systems. The immediate use of the Portascanner® lies in its improvement of the final stage of room integrity testing – for which it can vastly improve accuracy and operational efficiency. A device such as this has never been used before in this industry, and is the first to place emphasis directly on this important aspect of room integrity testing.
