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.

    About this Document: Determines the effect on previously completed claims due to changes in methods used in BWXT claims.

    Summary: No claim had a probability of causation of greater than or equal to 50% as a result of this reanalysis. One claim, however, had probability of causation between 45% and 50%. For that claim, the IREP program was run 30 times at 10,000 iterations in accordance with NIOSH procedures. The probability of causation remained below 50%. NIOSH provided the Department of Labor with the list of all the claims evaluated under this PER. Since all claims were below 50%, NIOSH did not request the return of any of the claims.

To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs) page.

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 BWX Technologies, Inc.:

At the current time, worker outreach activities have not been scheduled.
