In order to grow the business, a new nuclear station costing $6bn is being considered for which Maxwell is trying to raise finance. A nuclear plant takes about five years to build (assuming no regulatory difficulties or problems over the design choice). It has a working life of 40 years and costs about $1bn at current prices to decommission although this estimate is uncertain as each site is unique in the decommissioning difficulties which it presents.
Discussion
You are not expected to be experts in nuclear power plant construction (or in any other type of business). Always look for information provided in the question that you can use. You can then often expand that information to make additional points.
Here you are required to look at the whole-life costing issues of a nuclear power station, from initial planning all the way through to decommissioning 40 years hence. Sometimes it is worth imagining yourself having to perform an exercise for real: you are the accountant responsible for the lifecycle costing: what figures are you going to put into your calculations? Where will you have difficulties?
Examiner’s comments
Part (b) for 6 marks required a discussion of lifecycle costing issues associated with the plan to build a new nuclear power station. This part was poorly done by some candidates who simply discussed what the product lifecycle is with no reference to lifecycle costing. The key elements that were specific to this scenario were the design stage issues and the decommissioning costs and these were often ignored and the focus was on the growth, maturity and decline phases of a product without consideration that the end-product was electricity.
Suggested answer
Lifecycle costing takes all the costs of an undertaking into account: design and development, marketing, production, environmental costs, post-production costs (such as clean-up and scrapping costs). If a project is to be worthwhile total revenues over the project's life should cover total costs incurred over its life.
The particular costing issues arising when applying lifecycle costing to the proposed nuclear power station are:
Initial phase
These include complying with regulatory authorities (such as nuclear safety and security concerns) and designing the power plant. Almost certainly there will be a requirement to amend some parts of the design to satisfy safety, environmental and public objections. Not only is there a high chance that the project will be delayed (inevitably causing costs) but the design eventually chosen will have implications for constructing, running and decommissioning the plant. The estimated $6bn cost is likely to be incorrect.
Production phase
It is expected that the plant will last for 40 years, but it is obvious that the actual use of the plant could be different, so lifetime running costs will vary. In addition, the raw materials used by the plant, labour costs, security costs, environmental protection costs and so on will have to be estimated over a very long time-horizon and so must inevitably be difficult to estimate.
Decommissioning phase
We are told these will be about $1bn at current prices although this estimate is uncertain as each site is unique in the decommissioning difficulties which it presents. In addition, after the plant is no longer being used there will be on-going costs, possibly for many decades, for storing radioactive waste material safely and securely. These cost will be very difficult to estimate indeed.
