Qualitative / deterministic risk assessment
Safety and risk management: help or hindrance to innovation?
There is a common perception in industry that safety and risk management can be a blocker to progress and innovation, or that it is a ‘tick box’ exercise to be endured rather than embraced.
Proportionality – avoiding ‘one size fits all’ solutions
Proportionality is a fundamental attribute of modern risk management.
Common law – the harmonisation of european rail safety
The Common Safety Method on Risk Evaluation and Assessment (CSM REA) became a legal requirement in July 2012 throughout European member states. It applies to proposers of all significant changes to mainline railways.
Wind of change
It is now widely accepted that global temperatures are increasing due to the increased emission of greenhouse gases trapping the sun's heat in the Earth's atmosphere.
Small but mighty: an introduction to Small Modular Reactors
The size of civil nuclear power reactor units has steadily grown from 60 MWe in the 1950s to today's 1600+ MWe, driven by economies of scale. So too has the capital investment required, to the extent that funding new nuclear power stations is becoming prohibitively expensive for many nations.
Deterministic or probabilistic analysis?
The goal of safety assessment is to demonstrate that the risk associated with the construction, operation or decommissioning of any facility is at an acceptable level. One of the questions that people sometimes ask is, "which analysis techniques should be used to determine whether this goal is achieved?"
Nuclear decommissioning demands new thinking
To achieve the stringent levels of safety required over their lifetime, nuclear power plants rely heavily on engineered safeguards. Other industries, where consequences are less severe, rely more on procedural controls and operator action to manage risks. Understandably, the emphasis has been on designing new operating facilities and upgrading existing facilities to meet improving standards.
The brownfield revolution
In 2007 the UK Government agreed to an overall European Union target of generating 20% of EU's energy supply from renewable sources by 2020. As industry tries to turn this promise into power, it's finding that one of the most substantial obstacles to the proliferation of wind power in the UK is obtaining land for which planning consent is likely to be granted to erect wind turbines.
The Matrix Reloaded – our guide to the risk assessment matrix
The humble Risk Assessment Matrix (RAM) comes in for a lot of criticism. Whilst some of this may be justified, some arises more from a misunderstanding of the purpose and intended use of the RAM. There are strong views expressed on both sides of the argument (see Refs. 1 and 2 for example). Here, we provide practical guidance on some of the more common issues.
Hydrogen future: safety assessment of hydrogen facilities
Hydrogen is increasingly being used as a transport fuel in Fuel Cell Electrical Vehicles (FCEVs) thanks to its environmentally friendly nature and increasing availability from water electrolysis or steam reforming.
