3.1 Technical Overview3.1.9 Technical Recommendation for LAr Tank Option

12

Based on the overall result of the Technical, Cost and Schedule comparisonsof the Baseline and Membrane Tanks, it is Technodyne's technicalrecommendation (fully supported by the other industrial and scientific

partners in terms of cost and schedule) that the GTT GST/Mark IIImembrane tank design concept should be developed further for thenext stages of LAGUNA LBNO

This may involve prototype or small scale experiments to investigate areas of

the tank and detector integration where further information is considerednecessary

20 ktonne & 100ktonne membrane tank designs were not generated as part ofthis study. It was agreed that a 50 ktonne design only should be fully evaluated

to establish design, procurement and construction costs/schedule to allow directcomparison with the 50 ktonne baseline steel/steel tank design.

Once a decision is made to proceed with either the baseline or the membranetank design, then a further decision will be made as to any requirement todevelop similar 20 ktonne & 100ktonne membrane tank designs.
