Security Rated Nuclear Facilities


Security Rated Walls for Multinational Defence, Security and Aerospace company.

Successfully delivering a project in the nuclear sector takes patience, persistence and not least precision, especially when there is the underlying, ever-present threat of terrorism, theft or sabotage.

When the end user of the project is a multinational defence, security and aerospace company that develops and manufactures central components for nuclear weapons, you know there is no margin for error.

Fortunately, that didn’t faze the team at Securiclad, when they were asked to tender for a flagship, Surrey-based project that involved the production of some 2,200m² of composite panels to create a security rated external superstructure to the LPS1175 SR4 security standard.

It also needed to be Fire Rated and thermally efficient with an excellent U value as well as being lightweight and versatile.

Securiclad is used to working to the demanding specifications from the nuclear sector and meeting stringent requirements as Mike McColl, managing director, Securiclad points out: ”Having undertaken similar work in the nuclear sector in the past, we knew we could deliver this project and our diligence in the pre-qualification stage lead to a positive outcome.”

Securiclad’s team of CAD Engineers assisted in the architectural and post-award design phases and the Sales and Projects Department engaged in an overall pre-qualification phase that lasted more than a year.  The team liaised with design consultants, security consultants, cost consultants, architects and main contractors, such was the meticulous attention to detail.

McColl adds that “What is evident in the end result of the year-long process is the team’s dedication and commitment to reaching the right solution for our customer’s project.”

Securiclad’s experience and expertise in manufacturing panels for security rated nuclear facilities have garnered them a range of high-security credentials, from LPS1175 SR2 to SR5 and are Government approved.  Securiclad also holds European EN1063 BR2 and BR3 certification, meaning that they can withstand the firepower of a 357 Magnum calibre handgun.

Added to that is the fact that the panels can provide protection from persistent attack by tools including, disc grinders, felling axes, jigsaws, drills and sledgehammers.

McColl explains: “Having been assessed on our technical and design capability at each stage of the process, we showed that we could satisfy all areas of design and development for this, particularly demanding project.  We were also able to prove that we could offer the most cost-effective, modern, security building method.”

The innovative Securiclad system is extremely flexible and because it can be assembled quickly, it saves time and simultaneously reduces disruption to sites and services.

Once the project was given the green light and the system was specified, Securiclad engaged with preferred contractor, Hardy Sherwood (special Projects) Ltd, a company with a workforce trained and experienced in the installation of the Securiclad product. Hardy Sherwood had also beaten off stiff competition to be awarded the subcontracting contract for the construction of the entire superstructure envelope.

Julian Dear, owner and managing director of Hardy Sherwood is full of praise for Securiclad. “The team at Securiclad was helpful in every way, accommodating us at all stages of the tender process which helped us to secure the work during the final negotiations.

“The technical backup and information issued during the tender stage was first class and they were open to our suggestions regarding minor improvements in the overall installation process.

“Securiclad is very proactive at all stages of the process and work to a very high standard.”

The superstructure was completed on time and on budget.
