SSIN No.: 6835 IN 85-92 UNITED STATES
NUCLEAR REGULATORY COMMISSION
OFFICE OF INSPECTION AND ENFORCEMENT
WASHINGTON, D.C. 20555 December 2, 1985 IE INFORMATION NOTICE NO. 85-92: SURVEYS OF WASTES BEFORE DISPOSAL FROM
NUCLEAR REACTOR FACILITIES
Addressees
All production and utilization facilities, including nuclear power reactors
and research and test reactors, holding an operating license (OL) or construc- tion permit (CP).
Purpose
The purpose of this information notice is to supplement the guidance of IE
Circular 81-07 as it applies to surveys of solid waste materials before
disposal from nuclear reactor facilities. It is expected that recipients
will review the information for applicability to their facilities. However, this information notice does not constitute NRC requirements; therefore, no
specific action or licensee response is required.
Description of Circumstance:
Some questions have arisen concerning appropriate methods of surveying solid
waste materials for surface contamination before releasing them as nonradio- active (i.e., as wastes that do not contain NRC-licensed material).
Discussion:
The need to minimize the volume of radioactive waste generated and shipped
to commercial waste burial sites is recognized by the NRC and industry. Some
nuclear power plants have initiated programs to segregate waste generated in
radiologically controlled areas. Such programs can contribute to the reduction
in volume of radioactive waste; however, care should be taken to ensure that
no licensed radioactive material is released contrary to the provisions of
10 CFR Section 20.301. In practice, no radioactive (licensed) material means
no detectable radioactive material.
In 1981, IE Circular 81-07 was issued by the NRC. That circular provided
guidance on the control of radioactively contaminated material and identified
the extent to which licensees should survey for contamination. It did not
establish release limits. The criteria in the circular that addressed surface
contamination levels were based on the best information available at the time
and were related to the detection capability of portable survey instruments
8511270325
IN 85-92 December 2, 1985 equipped with thin-window "pancake" Geiger-Mueller (G.M.) probes, which respond
primarily to beta radiation. Monitoring of aggregated, packaged material was
not addressed. In 1981, there was no major emphasis on segregating waste from
designated contamination areas. As a consequence, large volumes of monitored
wastes were not being released for unrestricted disposal. However, because
of recent emphasis on minimizing the volume of radioactive waste, current prac- tices at many nuclear power facilities result in large volumes of segregated, monitored wastes, containing large total surface areas, being released'as
"clean" waste.
When scanning surfaces with a hand-held pancake probe, there is a chance that
some contamination will not be detected. (See the papers by Sommers,' for
example.) There is the chance also that the total surface area will not be
scanned completely. Thus, when numerous items of "clean"-material (e.g.,
paper and plastic items) are combined, the accumulation of small amounts of
contamination that have escaped detection with the pancake probe may be detected
using a detector that is sensitive to gamma radiation (e.g., by using a sensi- tive scintillation detector in a low-background area). Such measurements of
packaged clean waste before disposal can reduce the likelihood that contaminated
waste will be disposed of as clean waste, then found to be contaminated after
disposal. (Some operators of sanitary landfills have begun to survey incoming
waste. for radioactivity using scintillation survey meters which in some cases
are supplemented by portable gamma-ray spectrometers.2)
In order to preclude the unintentional release of radioactive materials, a
good monitoring program likely would include the following:
1. Careful surveys, using methods (equipment and techniques) for detecting
very low levels of radioactivity, are made of materials that may be
contaminated and that are to be disposed of as clean waste. These
survey methods should provide licensees with reasonable assurance that
licensed material is not being released from their control.
2. Surveys conducted with portable survey instruments using pancake G.M.
probes are generally more appropriate for small items and small areas
because of the loss of detection sensitivity created by moving the probe
and the difficulties in completely scanning large areas. This-does not
preclude their use for larger items and areas, if supplemented-by other
survey equipment or techniques.
3. Final measurements of each package (e.g., bag or drum) of aggregated
wastes are performed to ensure that there has not been an accumulation
of licensed material resulting from a buildup of multiple, nondetectable
quantities (e.g., final measurements using sensitive scintillation
detectors in low-background areas).
