Action plan for response to abnormal conditions in Hanford Site radioactive waste tanks containing ferrocyanide. Revision 2

摘要

This action plan describes the administrative controls, monitoring frequencies, monitoring criteria, and reporting requirements that have been implemented for the Ferrocyanide Watch List tanks. In addition, corrective actions have been outlined where a response to an abnormal condition in a Ferrocyanide Watch List tank is warranted. Such responses may be due to changes in tank temperatures or pressures; flammable or toxic vapor concentrations, or airborne radiation levels. Additionally, this plan identifies source documents that detail the following: the criteria and specification limits required for ensuring that Ferrocyanide Watch List tanks are maintained in a SAFE or CONDITIONALLY SAFE state; response actions for prevention or mitigation of the consequences of an abnormal condition; and organizational responsibilities for ensuring that ferrocyanide tanks are maintained in a SAFE or CONDITIONALLY SAFE state and for responding to abnormal conditions.
