The economic costs of underground storage are high. However, given that nuclear power is necessary to avoid what would likely be a very significant amount of economic harm, specifically from global warming. For example, it has been projected that not doing anything to address climate change would result in an overall increase in temperate of 5 degrees Celsius which would lead to economic costs in the order of $74 trillion. This means that the need for nuclear waste storage is inevitable.1  As such, whilst underground storage does cost more than alternate options, it is as mentioned within the proposition case the safest and most reliable method of nuclear waste storage. As such, proposition is willing to take the harm of extra cost in order to prevent harm to people’s health and well being.  Ackerman, Frank.
