Anomalies
Start of testing, which was otherwise scheduled to being Monday the 18
th
of February, had to be
postponed for two days. Friday afternoon, the week before, there had been an accident with a
Soap stone slow heat release appliance, which slipped of the fork lifter upon dismantling from the
test rig. Several test rig accessories were broken irreparable and had to be replaced. The test rig
was not fully operational again until Wednesday the 20
th
of February. The incident is recorded in
DTI’s workplace safety system.
The camera ran out of power late in the morning, so pictures of the firebed at the end of the Cold
start is missing. Further, the image of loading of the MF fuel load was delayed approximately 5
minutes (please see appendix 3) All events could however be reconstructed from the set of logger
data.
