FM 8.2 Exhibit RB Temperature Data from 1992 BS Event 1 pg 1 of 4 The attached graph is from strip chart recorder AH-1003-TIR. Among many other data points, there are four RB temperature thermocouples that monitor containment temperature:

Point 5:

Point 6:

Point 7:

Point 8:

AH-536-TE El. 102'-9" AH-537-TE El. 125'-0" AH-538-TE El. 180'-6" AH-539-TE El. 235'-0" The data indicates that Point 7 and Point 8 each dropped about 6 degrees during the spray event. The other two points actually increased about 2 degrees.

The data points monitored by AH-1003-TIR are shown on the attached Instrument Data Sheet, and the actual locations of the thermocouples are shown on attached drawing 308-695.
