We develop bespoke fire safety solutions for nuclear facilities, integrating regulatory requirements, radiation protection and technical feasibility throughout all phases of operation.
Safety is the top priority at nuclear facilities. Fire safety is a key component in ensuring the protection of staff, the public and the environment. In addition to building regulations, ordinances and guidelines, particular attention must be paid to the Atomic Energy Act, the Radiation Protection Act, the Radiation Protection Ordinance and the rules of the Nuclear Safety Committee (KTA).
Due to the specific requirements of radiation protection, standard fire safety solutions – such as those commonly used in industrial construction – cannot be implemented directly in radiation protection areas. For example, smoke extraction in the event of a fire would conflict with the protection objective of preventing the release of radioactive substances. Tailored solutions must therefore combine the protection objectives and specific requirements of radiation protection with those of fire safety. This applies throughout all operational phases of a facility, from planning and new construction through operational use to decommissioning and dismantling.
Our experts can assist you with this task in all facilities involving ionising radiation, e.g. nuclear power stations, waste treatment facilities, facilities for the processing of radioactive materials, interim and final storage facilities, as well as research reactors and research institutions.

We draw up site-specific fire safety plans (phases 1 to 4 in accordance with AHO), technical fire safety reports and expert opinions, taking into account building regulations, radiation protection requirements and usage-specific requirements.
We assist in reconciling the requirements set out in the fire safety documentation (usually the fire safety concept) and the planning permission with the results of the detailed design, in order to avoid unnecessary iterative design stages.
We check that the necessary fire safety equipment has been installed correctly and that relevant regulations are being complied with, in order to avoid costly retrofitting work at a later stage.
We draw up the necessary planning documents in accordance with the applicable regulations and official requirements, and check that they are up to date

Fire safety measures are designed to protect staff, the public and the environment. A key feature is that these measures must limit fire risks whilst at the same time preventing the release of radioactive substances. For this reason, in addition to building regulations, nuclear legislation and radiation protection legislation apply, with specific rules (e.g. KTA).
In addition to building regulations, the Atomic Energy Act (AtG), the Radiation Protection Act (StrlSchG), the Radiation Protection Ordinance (StrlSchV) and the rules of the Nuclear Safety Commission (KTA) are particularly relevant.
In radiation protection areas, standard measures (e.g. conventional smoke extraction) may conflict with the aim of preventing the release of radioactive substances. Solutions must therefore be specifically adapted to meet radiation protection requirements.
Key factors include the strict separation of redundant safety systems, higher requirements for availability and documentation, specialised cabling and plant designs, enhanced emergency planning and on-site fire services, as well as regular safety assessments (both deterministic and risk-based).
Through tailored, site-specific concepts that incorporate both safety objectives: preventing the outbreak and spread of fire, and preventing the release of radioactive substances. This encompasses requirements relating to building regulations, operational procedures and radiation protection legislation.
Fire safety plans must be site-specific; in other words, they must always relate to a specific building or facility. A fire safety plan must contain all the information required to assess the building or facility in terms of structural, technical, organisational and protective fire safety measures. In some federal states, the content is specified by regulations or administrative provisions.
Redundancy separation ensures that the effects of fire (and consequential damage) do not affect several safety-critical, redundant systems simultaneously. This is achieved through fire compartments, minimum clearances, fire resistance ratings, independent routing or separate supply systems.
The level of site supervision, i.e. the depth of the inspection, is described in AHO, Booklet 17. The specialist fire safety site manager usually carries out spot checks to verify that fire safety installations (building materials and components) have been fitted correctly and that relevant regulations and requirements set out in the planning permission have been complied with. This enables problems to be identified at an early stage and costly retrofitting to be avoided.
