DATES: Comments, data, views, or arguments concerning this
recommendation are due on or before October 17, 1994.
ADDRESSES: Send comments, data, views, or arguments concerning this
recommendation to: Defense Nuclear Facilities Safety Board, 625 Indiana
Avenue NW., Suite 700, Washington, DC 20004-2901.
FOR FURTHER INFORMATION CONTACT:
Kenneth M. Pusateri or Carole C. Morgan, at the address above or
telephone (202) 208-6400.
Dated: September 12, 1994.

Chairman.

The high-level radioactive wastes that are a result of weapons
material production have been the strong focus of waste management
activities of the Department of Energy (DOE). Considerably less
attention has been placed upon the large volumes of low-level
radioactive waste that have been generated to date and that are
projected for the future. Operation of waste management facilities and
the maintenance of the defense nuclear complex will continue to
generate considerable low-level waste and the need for adequate waste
storage and disposal facilities. This volume is likely to increase
dramatically with the decommissioning and decontamination of excess
facilities.
The Board and its staff have been reviewing low-level waste
management within the defense nuclear complex pursuant to 42 U.S.C.
2286a(a)(1), which requires the Board to review and evaluate the
content and implementation of standards, including DOE orders and
regulations, at defense nuclear facilities. DOE Order 5820.2A,
Radioactive Waste Management, and the Nuclear Regulatory Commission's
regulation on low-level waste disposal, Code of Federal Regulations
Section 10 Part 61, have provided the basic frame of reference for this
review. Further, it was useful to examine the low-level waste
management program of the Department in terms of its past, present, and
the future operations.
The results of our review are summarized as follows:
As of 1993, the DOE and its predecessor agencies have
buried approximately 2.8 million cubic meters of low-level radioactive
waste. This waste has largely been disposed of at six sites through the
use of shallow land burial--Savannah River Site, Hanford, Idaho
National Engineering Laboratory, Oak Ridge National Laboratory, Nevada
Test Site, and Los Alamos National Laboratory.
Low-level waste disposal as practiced by DOE contractors
has not kept pace with the evolution of commercial practices. For
example, DOE disposal programs are generally characterized by minimal
barriers to infiltration and biologic intrusion, no requirements to
protect inadvertent human intruders, and operational practices not
geared toward maintaining integrity of the waste form and the cover.
In 1988, DOE issued Order 5820.2A, Radioactive Waste
Management, which adopted the basic performance objectives of the
Nuclear Regulatory Commission's 10 CFR part 61. A key feature of the
Order is the requirement to prepare a Performance Assessment (PA). This
Performance Assessment is intended to demonstrate that the buried waste
will remain sufficiently confined to pose no undue risk to public
health and safety. Although the Order was issued six years ago, no
defense nuclear facilities site has to date completed the performance
assessment process.
In establishing low-level waste burial ground source
terms, current DOE guidance for performance assessments required by DOE
Order 5820.2A allows the evaluators to neglect waste disposed of prior
to 1988. Further, it allows evaluators to apply reference dose criteria
to disposal facilities individually rather than assessing composite
effects when contiguous burial facilities exist. A number of other
factors also complicate site specific assessments. For example: (1) A
commercial low-level waste burial site is situated adjacent to a DOE
burial site at Hanford; (2) some sites have multiple burial grounds, a
situation not explicitly addressed by DOE Order 5820.2A; and (3)
agreements have been established with State/Environmental Protection
Agency authorities for closeout of some burial sites under the Resource
Conservation Recovery Act and the Comprehensive Environmental Response,
Compensation, and Liability Act provisions.
Some effort is being made by those tasked with site waste
management to have generators of waste provide long-range forecasts of
the amount of wastes they will have to send for disposal, but the
forecasts are beset with such uncertainty as to provide little
confidence in the projections. This is especially true as the
projections pertain to wastes from decontamination and decommissioning,
and environmental restoration.
The DOE's burial of low-level waste in some locations within the
complex actually constitutes nuclear waste storage, since inadequate
emplacement may require later retrieval of the waste, further
processing or packaging, and final disposal in a demonstrably adequate
facility. Given the substantial volume of low-level waste buried prior
to 1988 in old burial sites using practices which do not meet current
standards, the lack of complete compliance with requirements of DOE
Order 5820.2A at currently operating sites, and the likely dramatic
increase in future waste volumes, the Board recommends that:
1. A comprehensive complex-wide review be made of the low-level
waste issue similar to the review the Department conducted regarding
spent nuclear fuel. As with spent fuel, the objective of such review
should be the establishment of the dimensions of the low-level waste
problem and the identification of necessary corrective actions to
address safe disposition of past, present, and future volumes. The
Implementation Plan provided the Board should include:
a. A regularized program for forecasting future burial needs
relative to existing capacity, taking into account the projected
programs for decontamination and decommissioning of defense nuclear
facilities and environmental restoration activities as well as current
operational units.
b. The development and issuance of additional requirements,
standards or guidance on low-level waste management that address safety
aspects of waste form and packaging, burial ground siting and
performance assessment, facility design, construction, operation, and
closure, and environmental monitoring. Such guidance should reflect
consideration of concepts of good practices in low-level waste
management as applied in the commercial sector, both nationally and
internationally, and results of DOE's technological developments and
advisories to the State Compacts pursuant to the Low Level Radioactive
Waste Nuclear Waste Policy Act of 1982, as amended.
c. Planned studies directed towards (1) improving modeling and
predictive capability for assessing migration of radionuclides and (2)
enhancing the stability of buried waste forms, deterring intrusion and
inhibiting migration of radionuclides.
d. Studies of enhanced methods that can be used to reduce the
volume of waste to be disposed of, such as compaction and more
environmentally acceptable incineration.
e. Assessments of the safety merits/demerits of privatization of
facilities for disposal of DOE low-levels wastes.
2. More immediate steps be taken to complete the performance
assessment process for all active low-level waste burial sites as
required by DOE Order 5820.2A. In so doing clarifying instructions
should be issued to insure that:
a. Performance assessments are based upon the total inventories
(past, present, and future) emplaced or planned for the burial site(s).
b. Performance objectives (dose criteria) of DOE Order 5820.2A are
achieved for the composite of all low-level waste disposal facilities
on the site.
3. If non-compliance with reference dose criteria set forth in DOE
Order 5820.2A is found, an action plan with schedule be developed for
bringing operations into compliance or other acceptable compensating
measures be undertaken in the interim pending final closure.
