Radiation Dose Reconstruction

 

Chapman Valve
(Site Profile/Docket Number 042)

Location: Indian Orchard, Massachusetts

Also known as: Chapman Valve Manufacturing Co.
                         Crane Co.

Technical Basis Document


Chapman Valve Manufacturing, Indian Orchard, Massachusetts
(Revised September 12, 2008)
this document in PDF PDF 453 KB (33 pages)

Revision Includes: Incorporates OCAS changes and updated references. Incorporated new information: dates of uranium fires, period of operation, details of plant processes, facility layout, radiological control practices, and radiological monitoring results. Updated information on the date of the uranium fire resulted in changes in the internal exposure scenario. Added the Dean Street location to the facility description based on new information from the DOE. Constitutes a total rewrite of the document. Incorporates formal internal and NIOSH review comments.

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.

  • PER 22: Chapman Valve TBD Revision
    this document in PDF PDF 15 KB (1 page)

    Document Number: OCAS-PER-0022 Rev-00

    About this Document: New document to determine which previously completed claims require evaluation for the effect of revising the Chapman Valve TBD.

    Approved: September 20, 2007

    Summary: There were 31 Chapman Valve claims completed with a probability of causation below 50% prior to the revision to the TBD. Twenty one of these were completed using TIB 4. Because that document describes a higher dose estimate than the revision to the Chapman Valve TBD, no further evaluation is necessary for those claims. The remaining 10 Chapman Valve claims were completed using revision 0 of the Technical Basis Document. 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 Chapman Valve 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 Chapman Valve:

Advisory Board Work Group on Chapman Valve

This Work Group is responsible for reviewing the SEC petition from the Chapman Valve petitioners, reviewing the NIOSH Evaluation Report of the petition, considering issues raised by the Board's contractor (SC&A), and for assisting NIOSH and SC&A in the resolution of such issues. The Work Group may recommend to the Board, changes in the site profile as appropriate. The Work Group should strive to develop a recommendation to the Board on whether a class should be added to the SEC.

      Please note that as part of the procedures and processes of the Advisory Board's Work Groups, several kinds of pre-decisional documents may be developed. These documents, which can include white papers, matrices, working drafts, etc., are distributed among the Work Group members as research and background tools to facilitate discussion and deliberation. The discussions during the above meeting may cover a pre-decisional document. Because these types of documents are pre-decisional in nature, may contain sensitive information, and may change over time, they are not posted on our Web site.

      Revision Includes: Replaced boilerplate language in Section 1.0. Added information from February 2005 Worker Outreach meeting. Added additional claim-supplied information. Added discussion supporting assumption of unenriched uranium. Added information regarding the use of a furnace/incinerator and provided a comparison of internal exposures to NUMEC incinerator operators with derived Chapman Valve exposures. Added information on the radiological safety program from a 1952 newspaper account. Added information regarding the month of the previously reported 1948 fire. Provided information developed for SEC petition evaluation report. Reanalyzed intake regimes as directed by OCAS using the largest of the 40 results not associated with the fire, 0.03 mg/L, for each sampling period to calculate a non-fire intake rate, and using the largest result associated with the fire, 0.08 mg/L, for the June 11, 1948 result, and keeping the other results the same as for the nonfire scenario to calculate the fire-associated intake scenario. Both intake scenarios are directed to be constant distributions in IREP. Added a comparison of Chapman derived air concentrations with air concentrations measured at other facilities. Added figures showing location of chip burner and dust, debris and soil sampling.

      Corrected two residual radioactivity external exposure values (increased rates by a factor of 2). Incorporated formal internal review comments, NIOSH and DOL comments. This revision results in an increase in assigned dose.
