SSEM/20<strong>11</strong>/4730 June 20<strong>11</strong>7.2 Application of BAT <strong>for</strong> beach monitoring7.2.1 Introduction<strong>Sellafield</strong> <strong>Ltd</strong> is required to ensure that best practice is used to meet the objectives of beachmonitoring. This has been specified in the CEAR <strong>for</strong> paragraph 19 schedule 1 of theAuthorisation since the start of the large area programme. The current wording is below: Since the commencement of large area beach monitoring several pieces of work have beenundertaken to ensure the application of best practice. In 2008 Serco were awarded acontract to investigate the BPM options <strong>for</strong> beach monitoring. The work involved a deskstudy, technical workshop <strong>and</strong> a BPM study (Serco/TAS/2301/002). Using the Serco studyas a basis, the BPM approach was determined by <strong>Sellafield</strong> <strong>Ltd</strong> at the start of 2009(Desmond, 2009). The Serco reports <strong>and</strong> the BPM determination were peer reviewed byEntec on behalf of the EA. Progress against recommendations from BPM determination weremade in March <strong>2010</strong> (Dalton, <strong>2010</strong>a), a review of techniques by Serco in September <strong>2010</strong>(Locke, <strong>2010</strong>) <strong>and</strong> an updated BPM determination was completed in March 20<strong>11</strong> (Dalton,<strong>2010</strong>b). Another review of techniques is scheduled <strong>for</strong> October 20<strong>11</strong>.7.2.2 Beach monitoring detection equipmentFor the latest BPM determination, in<strong>for</strong>mation on the technical development <strong>and</strong> utilisation ofthese techniques has been gathered by web-searches, examination of manufacturer’sin<strong>for</strong>mation <strong>and</strong> by personal contact with other experts in the field. The basic in<strong>for</strong>mation <strong>for</strong>each technique has been updated <strong>and</strong> the Ministry of Defence Technology Readiness Levelscale has been used to assess whether or not the technique has advanced sufficiently to beconsidered <strong>for</strong> this application. For those new techniques which showed the most promise acomparison was made against the current beach monitoring best practice.
