What people know about this machine
“BR-204 tends to recover slowly after cooling-loop maintenance.”
J
Jens Müller
Senior Production Technician · 11 yrs on BR-204
“Cooling felt slower than usual right after lunch break on 17 Sep.”
J
Jonas Lind
Operator, shift B · 4 yrs on BR-204
“Agitator noise rises a little before the vibration alarm ever trips.”
H
Henrik Sørensen
Process Engineer · 9 yrs on BR-204
“The CV-204 actuator needs a full stroke test, not just a bump test.”
M
Mette Dahl
Maintenance Lead · 14 yrs on BR-204

What the Brain has learned
KB-204-032 · from BR-204 investigation · DEC-204-0917
Post-maintenance cooling response should be verified before the next production run.
Validated learningKNOWN
KB-204-019 · from QR-2291
CV-204 actuator calibration must be re-run after any replacement.
Validated learningKNOWN
KB-204-024 · from EV-1187 · QR-2291 · DEV-204-017
Slow recovery after cooling-loop work is a recurring pattern on this reactor (3 occurrences).
