Programme Performance Updates

NDA Sites Monthly Performance Updates

The NDA's Programme Update is a high level summary of performance at the NDA sites.

In the updates we give a summary of

  • schedule and cost performance at programme level;
  • items of interest related to site performance; and
  • safety information that relates to the reporting period.

The NDA has made clear its absolute commitment to the highest standards for health and safety, security and protection of the environment and expects its contractors to deliver sustained excellence in HSSE performance.

In the Safety section we give details on any reportable incidents and environmental impact that has occurred at an NDA site in the reporting period

Site Performance Overview - March 2008

Note: Due to the approval of plans to extend the Joint European Torus (JET) operations at Culham decommissioning work will now not start until the end of 2010. The current decommissioning programme is now on hold until this date.

Measuring programme performance

We measure programme performance by using Earned Value Performance Management. This compares the budgeted cost of work that was scheduled with the budgeted cost of work that was actually performed to determine schedule performance and the budgeted cost of work that was actually performed with its actual cost to determine cost performance.

Points of clarification for financial year 2007/8

For financial year 2007/8, with the exception of Sellafield, sites' budgets are not over pressured. Sites' budgets contain scope of work that matches released funding.

Points of clarification for financial year 2006/7

For financial year 2006/7 the NDA set budgets for sites that contained more scope of work than there was available funding to complete. This is referred to as the Over Pressured Budget. Setting over pressured budgets is a tactic to build the sites cost efficiency target into their baseline scope. It is important to note that sites can only carry out the total value of work in their budget by making the necessary savings to fund the over pressured work.
