Install Ventilation System for the Sodium Nitrite Makeup Tank (SNMUT)

Install a temporary ventilation system for the Sodium Nitrite Makeup Tank (SNMUT) to allow tank to vent directly to the atmosphere at the 422-S roof edge rather than through the 422-S acid vent system. This temporary modification revises Revision 0 of DWPF-TMC-15-022 that isolated the SNMUT from the acid vent system. Installing a temporary ventilation system on the SNMUT will eliminate compensatory actions found in the section 8 of Revision 0 of the temporary modification. The temporary ventilation will provide the same design exhaust flow rate from the SNMUT that the acid vent system provided.
