ES‐konsult performs safety analysis reports
ES‐konsult is implementing, reviewing and coordinating both probabilistic and deterministic safety analyses. The methods
are universal and are therefore not restricted to a specific industry even though the emphasis is on the nuclear industry.
ES‐konsult has extensive experience in working with risk and safety analyses in industries with high safety demands, such
as the nuclear industry, chemical processes and transportation industries to name some.
Within ES‐konsult's field of work, the nuclear industry, deterministic safety analyses are used to examine how well the
safety systems handle different incidents, that is to say how safe the plant is. For example, we have performed analyses of more or less probably
incidents in the plant, such as fires, floods, pipe breaks and earth quakes.
Probabilistic safety analyses are used to calculate the probability for certain incidents to happen. This is done by using
estimated probabilities for failure in components and systems. The objective is that every type of failure that can happen should be included
in the analysis. Then, by combining the possible states of the systems and components concerned Målet är att samtliga felmoder som kan
inträffa ska inkluderas i analysen.
The result of the analysis then forms the basis for further work and actions to reduce the identified risks. Risk and safety
analyses are very useful tools when running a technically complex business.
Exemples of performed work:
- Analysis of external steam pipe breaks at Ringhals 2
- Production of base load data and dynamic loads to be used in safety analyses at Forsmark
- Analysis of hydrogen explosions in the hydrogen-cooled generator at Ringhals 1
- Risk analysis of hydrogen as a transportation fuel for cars
- Ringhals 4, updating of the probabilistic safety analysis in connection to the power uprate project FREJ.
