The following information was received via E-mail:
The shutter on a SVP generator [chlorine dioxide] ClO2 density meter failed in the open position. This failure was identified and verified on Saturday, 7/13/19. Berthold inspected the gauge while they were on site on 7/19/19 and are scheduled to come in on the next C mill outage to replace the shield. Outage is tentatively scheduled for 10/9/19. The gauge shutter normally operates in the open position so the failure poses no safety risk during normal operations.
The SVP generator density meter is Rayonier instrument loop no. 507-081. The source is Cesium-137, 500 mCi, model 2623-100, serial no. ED350A in a LB7440 housing.
