Technical Basis Document
Chapman Valve Manufacturing, Indian Orchard, Massachusetts
(Revised September 12, 2008)
 PDF 356 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 compensability of a completed dose reconstruction may be effected, 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
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:

- Revised October 16, 2006
PDF 252 KB (32 pages)
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.
