Meeting Summaries for Development of the Hanford Site C Tank Farm Performance Assessment

The Meeting Summaries for Development of the Hanford Site C Tank Farm Performance Assessment cover informal discussions between representatives of the U.S. Department of Energy (DOE), U.S. Environmental Protection Agency (EPA), the U.S. Nuclear Regulatory Commission (NRC), and the Washington State Department of Ecology (Ecology) and involvement with Tribal Nations, State of Oregon, and the Hanford Advisory Board to support DOE’s preparation of a new performance assessment (PA) for the Hanford Site C Tank Farm (CTF). These discussions will include the underlying assumptions, input parameters, and modeling approaches to be taken in developing this assessment. These working sessions are intended to facilitate preparation of a performance assessment that meets the needs of each of the agencies. Once completed, the CTF PA document will undergo review by the NRC, Ecology, and EPA. DOE prepares a summary of each of the informal working sessions.

DOE O 435.1 requirements and guidance (including DOE G 435.1-1, "Content and Format of a DOE Performance Assessment") will be the primary driver in the development of the CTF PA. Additionally, these tanks will be closed in coordination with Ecology and EPA in accordance with the Hanford Federal Facility Agreement and Consent Order.

Currently, the Department of Energy-Hanford Site (DOE-ORP) is drafting a PA for their CTF. The CTF PA encompasses the closure of the entire CTF and will not be finalized until late spring of 2012.
