1. MERIT Primary Containment Inspection Van Graves MERIT Video Conference October 13, 2010

2. 2Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Mercury Primary Containment Inspection 17 Aug – Viewport 2 Sapphire windows removed No obvious surface damage noted Higher quality photographs to be obtained Jet & Beam Mercury Beads Jet & Beam Sapphire Window Gasket

3. 3Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 New Photographs Taken 10 Sept With 35mm Camera & Macro Lens Snout Orientation – Beam from Right Top of Container is Up Setup

4. 4Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Viewport 2 Upstream Side General surface appearance is uniform Jet

5. 5Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Viewport 2 Upstream Side Close-Ups

6. 6Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Viewport 2 downstream side Raw material labeling intact Jet SS Plate Label Hg Bead

7. 7Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Viewport 2 Top Jet

9. 9Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Other Viewports Have Similar Images VP1 Upstream VP3 Upstream

10. 10Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Primary Containment Microscopic Inspection Dissection of chamber around viewport 2 – Might require purchase of dedicated tool due to radiation & Hg issues – Would also allow sectioning of mercury nozzle piping Decontamination of pieces (includes sapphire viewports) Inspection with SNS scanning electron microscope Cost estimate: $25k

11. 11Managed by UT-Battelle for the U.S. Department of Energy MERIT Containment Inspection 13 Oct 2010 Observations Surface appearance consistent throughout interior of primary containment – standard, un-machined surface texture Higher resolution images do not support theory of mercury bead pitting, at least on a macroscopic level Further investigation possible by sectioning chamber, decontaminating and viewing pieces with microscope
