Current status, KO mock-up removed
•KO mock-up developed water leak at cycle 2383 in 12-mm-dia tube. Repair was not possible. Removed on 6/08/2009. •JA mock-up has partially un-bonded ss tubes since fabrication, but performing within acceptable margins.

Summary
• FWQM testing in Round 1 (completed 11/08)• EU & US passed Round 1 in US
•Waiting for MARFE/Additional in Judith in EU• Currently above 6300 cycles in Round 2 testing
•CN, JA, KO, RF MARFE testing in August•KO mock-up pulled, replacement for MARFE testing•JA 12-mm-tubes not well attached to CuCrZr
• Following next year – semi-prototype testing ?
