Savannah River Site (SRS)
(Site Profile/Docket Number 012)
Location: Aiken, South Carolina
Special Exposure Cohort Petition Information
The Special Exposure Cohort (SEC) is a unique category of employees established by the Act (42 CFR Part 83). Claims compensated under the SEC do not have to go through the dose reconstruction process. To qualify for compensation under the SEC, a covered employee must meet specific requirements (e.g., must have at least one of 22 “specified cancers,” and have worked for a specified time period at one of the SEC sites). Classes of employees and work sites can be considered for addition to the SEC through a NIOSH petition process. More information about the Special Exposure Cohort can be found on our Frequently Asked Questions page.
Open/Active SEC Petitions
There are currently no open/active SEC petitions from Savannah River Site (SRS).
Class(es) Added to the SEC
-
January 1, 1953 through September 30, 1972: All employees of the Department of Energy, its predecessor agencies, and their contractors and subcontractors who worked at the Savannah River Site from January 1, 1953, through September 30, 1972, for a number of work days aggregating at least 250 work days, occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees included in the Special Exposure Cohort.
Note: This class was established from Petition 103.
-
October 1, 1972, through December 31, 1990, with exclusions: All construction trade employees of Department of Energy subcontractors [excluding employees of the following prime contractors who worked at the Savannah River Site in Aiken, South Carolina, during the specified time periods: E. I. du Pont de Nemours and Company, October 1, 1972, through March 31, 1989; and Westinghouse Savannah River Company, April 1, 1989, through December 31, 1990], who worked at the Savannah River Site from October 1, 1972, through December 31, 1990, for a number of work days aggregating at least 250 work days, occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees included in the Special Exposure Cohort.
Note: This class was established from Petition 103.
Petitions Qualified for Evaluation
Below is a list of the petitions that qualified for evaluation. Select a petition on the list to view the table for that particular petition.
SEC Petitions Not Qualifying for Evaluation
In addition to the petitions listed above, three petitions were received but did not qualify for evaluation because they did not meet the minimum petition requirements.
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. Worker Outreach Activities for the Savannah River Site (SRS):

Agenda: This meeting has been scheduled to discuss the Savannah River Site, Site Profile document.
-
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.
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 (TBDs), and Technical Information Bulletins (TIBs). To learn more about these documents, please visit our Technical Documents Used in Dose Reconstruction page.
Site Profile/Technical Basis Documents
-
Revised: April 5, 2005

Site Description [6MB (119 pages)]
Revised: March 5, 2024
Revision Includes: Revision to separate site profile into an Introduction and five TBDs. Incorporated the latest boilerplate in the TBD. Expanded the descriptions of some of the facilities to provide additional information to dose reconstructors; added absorption types in the tables that represent the possibilities for the various radionuclides; eliminated Attachment A and incorporated the discussion and the tables in the main body. Expanded the discussion in Section 2.3.20 on tritium facilities to include additional history and process description; added a discussion of organically bound tritium and metal tritides. Revision to incorporate comments and guidance associated with issuance of two SEC classes implemented with Petition SEC-0103. Includes expanded details on major SRS operating areas. Replaced Attachment A with new list of radionuclides. Updated Special Exposure Cohort information in Section 2.1.3. Activity fractions for the radionuclides of concern were removed from the tables throughout, descriptive text and photographs were added for visualization, and production campaigns for the 300-M area were clarified. U-233 added to Table 2-28. Thorium specified as Th-232 in Tables 2-41, 2-47, 2-48, and 2-49. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.

Occupational Internal Dose [2 KB (78 pages)]
Revised: March 5, 2024
Revision Includes: Revised to update entire site profile and to separate it into six technical basis documents. This Part 5 was Section 4.0 of Revision 03. Revised to incorporate comments and guidance associated with issuance of two SEC classes implemented with Petition SEC-0103. Incorporates information from the internal co-exposure study (formerly ORAUT-OTIB-0081 and now ORAUT-TKBS-0003-7). Attributions and Annotations removed. Revised to include a thorough description and delineation of the types of uranium used and processed at SRS. Updated Section 5.6.4.2 to include reference to ORAUT-OTIB-0066 in OBT discussion and to edit unmonitored periods where co-exposure tritium dose is assigned in accordance with Table 7-18. Updated Section 5.6.3 to clarify whether and how to make comparisons between weapons-grade plutonium vs. nonmonotonic “pure” 238Pu for given facilities. Updated Section 5.6.5 to clarify where and how to apply the various uranium mixtures indicated tables other than NU and DU. Added a table in Section 5.6.5 that states which uranium mixture is to be applied for various facility codes by year range. Updated Section 5.6.9 to include wording to assume triple-separated thorium from 10/01/1972 to present. Updated Section 5.6.5.1 to clarify the “intakes to add” values in Table 5-31. Deleted “Uranium co-exposure intakes should be assigned to unmonitored workers while working in D Area from 1954 through 1988. Consult ORAUT-TKBS-0003-2 for rational.” from Section 5.6.5.3. Updated Section 5.6.7.1 to change 1988 to 1990 for the following statement: “FP co-exposure intakes should be assigned to unmonitored workers for work in D-Area from 1954 through 1988.” Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.

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

OCAS-PER-0001 Rev-00: Misinterpreted Dosimetry Records Resulting in an Underestimate of Missed Dose in Savannah River Site Dose Reconstructions [958 KB (4 pages)]
September 8, 2003About this Document: Describes the evaluation of the programmatic effect of the misinterpreted dosimetry records resulting in an underestimate of the missed dose for Savannah River Site dose reconstructions.
Summary: While the underestimated missed dose resulted in a non-claimant favorable estimate of missed dose, the overestimated onsite ambient dose offset this underestimate. As a result, no further evaluation is necessary because the offset still resulted in a slight claimant favorable bias in the dose estimate and resulting probability of causation.

OCAS-PER-0002 Rev-00: Error in Surrogate Organ Assignment Resulting in an Underestimate of X-ray Dose in Savannah River Site Dose Reconstructions [482 KB (4 pages)]
December 15, 2003About this Document: Describes the evaluation of the programmatic effect of an error in surrogate organ assignment resulting in a potential underestimate of the X-ray dose for certain Savannah River Site dose reconstructions.
Summary: An error in surrogate organ assignment for the liver, gall bladder and spleen (ovaries was assigned instead of lung) resulted in the underestimation of X-ray organ doses in three completed dose reconstructions. The impact on the probability of causation in these three cases has been evaluated and found to be minimal (<0.5%), and the probable compensability status of these claims was unaffected. No revision of any completed dose reconstructions is warranted; however, to preclude future occurrences of this error, revisions of several Technical Basis Documents has been initiated.

OCAS-PER-0019 Rev-00: Program Evaluation Report: The Effect of Additional Neutron Dose Data from the Savannah River Site [20 KB (2 pages)]
May 18, 2007About this Document: New document to report the impact of additional neutron dose data received from the Savannah River Site.
Summary: Dosimetry records are requested from the Savannah River Site for each claim received from the Department of Labor with Savannah River employment. This data is used in reconstructing the individuals’ radiation dose. The Savannah River site notified NIOSH that additional data pertaining to neutron dosimetry was not sent for several claims. The additional data has since been received and added to the original dosimetry data. Previously completed claims were re-evaluated to determine the affect of this new data on the individual claims. This Program Evaluation Report (PER) was prepared to report the results of that evaluation.

OCAS-PER-0030 Rev-00: Program Evaluation Report: Savannah River Site TBD Revisions [31 KB (3 pages)]
December 18, 2007About this Document: Document to determine which previously completed claims require evaluation for the effect of revising the Savannah River Site< TBD.
Summary: There were 54 Savannah River Site claims completed prior to August 21, 2003, (issue date of revision 1) with a probability of Causation below 50%. The dose reconstruction methodology of each will be reviewed to determine if a new dose reconstruction is necessary to determine if the revisions increase the dose estimate. NIOSH will review these dose reconstructions to determine if they meet any of the criteria listed in this PER. NIOSH will provide DOL with the list of 54 claims as well as a determination on each claim as to whether a new dose estimate is required. Documentation for each claim not requiring a new dose reconstruction will provide the basis for that determination.

ORAUT-TKBS-0003 Rev-02: Revised October 29, 2004 [4 MB (242 pages)]
Revision Includes: Allows use of Table C-17, Maximum site-wide annual intakes and geometric standard deviations, for all environmental dose reconstruction and clarifies periods of applicability. Modified instructions for determination of undetected dose from in vitro bioassay results (except tritium) below detection threshold. Clarified instructions for missed dose determination from whole body count results below the detection threshold. Corrected Ce-144 table 4.3-5. Pages changed are 24, 57, 58, 62, 72, 80, 81, 84, 85, 86, 89, 156, and 183. The Uncertainty Section (4.4.2) was deleted because it is not specific to SRS and because this avoids inconsistencies that might result from dose reconstruction programmatic changes. Incorporated medical x-ray changes and addition of section on photofluorography, addition of references, and information on TNX and CMX. Changed all dates referring to photofluorograph to 1951-1957. Removed reference to 1967.

Revised November 30, 2009 [581 KB (23 pages)]
Revision Includes: This revision is updated with newly acquired captured information. Includes Attributions and Annotations section. Specific changes are as follows: Added specific technique factors for PA and LAT projections for Type I machines and for LAT projections for Types II through IV machines in Table 3-3. Added Table 3-4. Rearranged the various sections and changed section headings: Section 3.3.1 changed from X-ray Apparatus to Photofluorography; Section 3.3.2 from Collimation to Radiography; Moved the existing section 3.4.2 on Collimation to Section 3.4. Added Section 3.3.3. Replaced the text in the existing Section 3.5 that contained example calculations of doses for the various projection types with two paragraphs of new text describing how doses were assigned. The original Table B.2 is now Table 3.9. All organ doses for the period 1950-1970 for Type I X-ray equipment have decreased; also doses for the male lungs and female bone marrow have been added. Entrance air kerma and skin doses for the PA and LAT projections have been deleted from Table 3-9. Table 3-10 and Table 3-11 have been added. The discussion regarding the four potential sources of uncertainty has been deleted except for the final statement to assume a +30% uncertainty at the 99% confidence level as stated in OTIB- 0006. Changed reported range on technique factors for the Picker machine. Values added to Table 3-3; The calculated entrance and exit skin doses were compared to the measured entrance and exit skin doses of Cooley (Cooley, 1967) made on the mobile Picker machine for the PA chest for the 1950-1970 time period. The comparison is shown in Table 3-7. The 21% uncertainty derived from the Cooley measurements is substituted into the root mean square calculation for combined uncertainty instead of the 10% value initially reported from this source of uncertainty in ORAUT-OTIB 0006 (2005). As a result of this substitution, the resulting combined, standard uncertainty is 34%, and rounded up to 35%. Skin doses were put into a different table format to more closely match the skin dose tools. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.
