SNUFFING STEAK S.O.P.
The idea of steam injection is a good one, but the system must be
maintained to benefit us in an emergency.
The following will be S.O.P. regarding the Dowtherm furnace steam snuff
system.
cv
1. The steam block valve located in the header above the Dowtherm
storage tank shall be opened and sealed at all times, and the seal number
shall be logged on the snuffing steam inspection sheet.
2. The upstream block valve around the steam FCV shall be opened, sealed,
and logged on the snuffing steam inspection sheet.
3. Each Monday on day shift, the reactor operator and lead operator will
inspect the steam snuff system. This will be done by first making a visual
inspection of the steam block valves to make sure they are open and second
isolating and stroking the steam FCV. Finally, the block valve before the
steam FCV shall be sealed again and the new seal numbers logged on the
inspection sheet. Any problems found with the steam system should be reported
to the Maintenance Coordinator at once.
4. The Dowtherm furnace should not be operated unless the steam snuff
system is in good operating condition.
