AWE Site Wide Documents

Technical Documents

If the energy employee’s personal radiation information is incomplete, NIOSH will use other sources to estimate the radiation dose. This may involve using technical documents called Site Profiles, Technical Basis Documents, and Technical Information Bulletins.

NIOSH developed the AWE site wide technical documents below to help complete dose reconstructions. You can find discussion papers, public comments, and previous versions of these documents on this page also.

  • Estimating the Maximum Plausible Dose to Workers at Atomic Weapons Employer Facilities-CANCELED

    Document Number: ORAUT-OTIB-0004 Rev-03 PC-2

    Note:This document is no longer needed for dose reconstructions. Information in this document has been superseded by other approved methodologies.

Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs)

NIOSH is committed to applying the best available science in dose reconstructions. In keeping with this commitment, completed cases with probabilities of causation less than 50% are reviewed as relevant new information becomes available. The results of these reviews are described in a Program Evaluation Report (PER). The PER details the effect, if any, of the new information on the completed dose reconstruction. If it appears that the new information may result in an increase in dose for a completed dose reconstruction with a probability of causation of less than 50%, NIOSH is committed to working with the Department of Labor to reopen and rework the dose reconstruction, as appropriate. A Program Evaluation Plan (PEP) describes plans for evaluating specific program details or issues.

NIOSH developed the PER and PEP documents below as relevant new information became available. You can find discussion papers on these documents on this page also.

  • PER 24 : General Steel Industries TBD Approval [14 KB (1 page)]
    September 25, 2007

    Document Number: OCAS-PER-0024 Rev-00

    About this Document: New document to determine which previously completed claims require evaluation for the effect of approving a GSI TBD.

    Approved: September 25, 2007

    Summary: There were 4 General Steel Industries claims completed with a probability of causation below 50% prior to the approval of the TBD. These were completed using ORAUT-OTIB-0004. Since the new document describes a higher dose for some of the dose estimate, it is necessary to revise these dose estimates to determine the effect. NIOSH is requesting that these claims be returned for a new dose estimate. A new dose reconstruction will be completed for each of the claims using the latest revision to the General Steel Industries TBD.

Worker Outreach Activities

Based on a recommendation from the Advisory Board to provide workers and site experts with opportunities to participate in developing the technical documents used in dose reconstruction, NIOSH established a Worker Outreach Program.

At Worker Outreach Meetings, current and former DOE and AWE employees have opportunities to obtain information about Site Profiles, Technical Basis Documents, and Technical Information Bulletins, and to provide information for consideration and possible use in dose reconstruction. This process is valuable to ensure that the technical documents used in dose reconstruction contain correct and useful information.

Below are the Worker Outreach Activities for AWE Site Wide Documents:

Advisory Board Work Group on TBD 6000

This Work Group is responsible for the review of the specified TBDs and the Appendices that apply to specific work sites. The Work Group will also review reports developed by the Board’s contractor (SC&A) pertaining to these TBDs and the Appendices. They will assist NIOSH and SC&A in resolving issues that arise through the review process. The Work Group will make recommendations to the Board in cases where Appendices involve sites with SEC petitions.

Sites currently being considered by the Work Group include:

Note: Baker Brothers, Bliss & Laughlin Steel, and Simonds Saw and Steel Company work sites were previously discussed by the TBD 6000 Work Group, but are not currently under discussion.

Pre-Decisional Document Policy

Please Note: As part of the procedures and processes of the Advisory Board's Work Groups, several kinds of pre-decisional documents may be developed. These pre-decisional documents, such as white papers, matrices, working drafts, etc., are distributed among Work Group members as research and background tools to facilitate discussion and deliberation. Although discussion during a public meeting may cover pre-decisional documents, these documents often are not further revised or finalized, and thus do not reflect the final determination or evaluation of the Advisory Board and its Work Groups. Additionally, some pre-decisional documents not otherwise posted on the website may contain sensitive information, which would require an interested party to obtain such documents by filing a Freedom of Information Act (FOIA) request with the CDC/ATSDR FOIA Office at FOIARequests@cdc.gov.

Advisory Board Work Group on Uranium Refining Atomic Weapons Employers (AWEs)–formerly TBD 6001 Work Group

    • Page Change Revision December 6, 2006 [285 KB (25 pages)]

      Document Number: ORAUT-OTIB-0004 Rev-03 PC-2

      Page Change Revision Includes: Removes Westinghouse Atomic Power Development Plant from Table B-1 in Attachment B on page 25, because their radiological activities included more than metallic uranium work. Updated required language in Purpose section on page 5. No further changes occurred as a result of internal formal review. Incorporated NIOSH formal review comment. This revision may result in an increase in assigned dose to Westinghouse Atomic Power Development Plant cases and a PER is required for Westinghouse Atomic Power Development Plant cases previously completed using this document.

    • Page Change Revision November 18, 2005 [196 KB (24 pages)]

    • Revised August 12, 2005 [258 KB (25 pages)]

      Document Number: ORAUT-OTIB-0004 Rev-03

      Revision Includes: Updates Appendix A, List of Applicable Facilities, and adds wording to clarify the application of the document. Allows for expansion to other facility types; includes estimate of industrial source exposures based on analyses of 1960-1980 commercial doses; deletes applicability (at this time) to U-recovery with phosphoric acid; adds type S assumption; used activity rather than mass air concentrations for calculations; uses different specific activity assumption for consistency with IMBA; uses OCAS-TIB-009 ingestion scenario; adds consideration of urinalysis; adds RU and EU assumptions; updates MCNP ingot doses; modifies ingot external dose assumptions; modifies external dose contamination calculation by accounting for isotopic fractions to consider effect of EU; removes external organ doses, but provides separate analyses (concern from Task 5 that reconstruction methods subject to their program should not be in Site Profile – the line is still blurry); added nonpenetrating dose assumptions; added photofluorography assumption prior to 1962. Corrected Table 3-8, first row to acute. Addressed OCAS comments: explicitly stated exception to default radiography doses could be made on a case-by-case basis, limited Appendix A industrial exposures to covered periods, and changed Appendix A industrial dose estimates back to linear (versus exponential) fit of data.

    • Revised December 4, 2003 [166 KB (13 pages)]

  • Site Profile for Atomic Weapons Employers that Refined Uranium and Thorium [446 KB (75 pages)]
    Approved December 13, 2006

    About this Document: This technical basis is established for the reconstruction of radiation doses of workers at AWE sites which refined uranium under contract to the United States government from 1942 to 1958. This document covers the generic aspects of uranium refining and the data are useful where no other dosimetry data exist. Site specific appendices are included that provide information that apply to only the identified site.

  • Site Profile for Atomic Weapons Employers that Worked Uranium and Thorium Metals [394 KB (57 pages)]
    Now titled “Site Profile for Atomic Weapons Employers that Worked Uranium Metals”
    Approved December 13, 2006

    About this Document: This document provides an exposure matrix for workers at AWE facilities that performed metal-working operations with uranium metal. Over 110 facilities performed these operations, and this document intends to provide guidance for dose reconstruction at any of these facilities. The main body of this document, in Sections 2-6, includes general discussions of operations and exposure conditions at these facilities. Following the main body of this document is a collection of appendices, with one appendix for each AWE site that performed metal-working operations. Each appendix contains site-specific information that can be used for dose reconstruction. For those sites where this information is insufficient or totally lacking, the dose reconstructor must use information in the main body of the Site Profile.

Advisory Board Work Group on TBD 6000/6001, Appendix BB

This Work Group no longer exists. In March 2010, this Work Group was divided into two separate Work Groups–Advisory Board Work Group on TBD 6000 and Advisory Board Work Group on TBD 6001.

This Work Group is responsible for the review of the specified TBDs as well as the Appendices that apply to specific work sites. They will also review any reports developed by the Board’s contractor (SC&A) pertaining to these TBDs and the Appendices, and will assist NIOSH and SC&A in resolving issues that arise through the review process. The initial focus of the Work Group will be on Appendix BB of TBD 6000, dealing with General Steel Industries. The Work Group will make recommendations to the Board in cases where Appendices involve sites with SEC petitions.
