Nuclear Plant Insulation

As the effects of climate change become increasingly evident and States recognize the significance of energy independence, it is imperative that we achieve a successful transition towards low-carbon energies such as wind, solar, hydraulic, and nuclear power.

While renewable energies are considered green due to their reliance on unlimited resources, their intermittency is an obstacle. On the other hand, nuclear power is a reliable and efficient complement to the low-carbon energy mix. It currently contributes around 10% to global electricity production, with 436 reactors operating worldwide and 59 under construction.

Insulating the ageing nuclear fleet

The average age of nuclear plants in advanced economies is 35 years, suggesting many facilities are approaching the end of their lifespan, with an estimated 25% of existing nuclear capacity expected to be retired by 2025. Therefore, significant investments will be made in the coming years to sustain the sector.

ISOVER offers a complete range of insulation solutions for the nuclear industry, meeting all potential needs, from thermal or acoustic insulation, to fire safety or corrosion prevention.

Benefits of nuclear insulation solutions

Insulation solutions play a crucial role in the nuclear industry by providing numerous benefits to plant owners, specifiers, EPCs, and contractors. Here are some of these key benefits:

Optimising energy officiency

By insulating pipes, ducts, and equipment, heat loss can be minimiszed, which reduces energy consumption and costs. This not only helps plant owners save money but also contributes to reducing CO₂ emissions.

Ensuring safety

In nuclear power plants, it is essential to maintain specific temperatures for various processes to operate safely and efficiently. Insulation solutions help maintain these temperatures by preventing heat loss or gain.

Meeting standards and regulations

High-performance insulation systems are also designed to meet specific requirements and regulations for thermal, acoustic, and fire performance. These requirements are particularly strict in the nuclear industry where safety and reliability are more critical than anywhere else.

Reducing installation time and labor costs

Finally, insulation solutions provide easy-to-use options for maintenance or new construction projects that can reduce installation time and labour costs. Contractors can rely on these solutions to provide approved insulation options for the nuclear industry while meeting specific requirements.

Our Insulation Solutions for Nuclear Applications

The demand on the quality of installed products is exceptionally high in nuclear power plants, especially in the nuclear island. ISOVER products are designed to meet nuclear industry requirements.

All our products used in the construction or renovation of nuclear power plants undergo special approval procedures. They are virtually free of organic content and therefore do not contribute to corrosion under insulation. All our products designed for the nuclear industry are approved by major industry players.

> TECH TELISOL 5.0 QN

TECH TELISOL 5.0 QN is a non-combustible insulation solution that has excellent thermal performances across a wide range of temperatures. It retains its long-term performance even when exposed to mechanical stress, making it suitable for use in the nuclear industry. It has been tested and certified to meet Euroclass A1 standards and has a fire spread index of 0 and smoke development index of less than 20.

> TECH LOOSE WOOL QN

TECH LOOSE WOOL QN is a non-bonded, resilient white glass mineral wool designed for use in the nuclear industry, particularly for insulation of dead spaces or joints. It is produced without the addition of silicone and is almost free of organic content to ensure that it does not contribute to the corrosion of stainless steel. The high resilience of its glass wool fibers guarantees a durable and long-lasting performance.

A complete range to insulate any nuclear application

Beyond these two flagship products, we offer a whole range of products tested and approved for use in the nuclear industry, all characterised by a low (or very low) organic content. Depending on the application to be insulated, you can choose from different formats, from loose wool to wired mats, slabs, and pipe sections.
