NRC INFORMATION NOTICE NO. 90-XX:
UPDATE ON WASTE FORM AND HIGH INTEGRITY CONTAINER TOPICAL REPORT REVIEW STATUS.
IDENTIFICATION OF PROBLEMS WITH CEMENT SOLIDIFICATION, AND REPORTING OF WASTE MISHAPS Addressees:
All holders of operating licenses or construction permits for nuclear power reactors, fuel cycle licenses, and certain by-product materials licenses.
Purpose:
+
This information notice is being provided to inform addressees of recent developments concerning the stabilitc/ of waste forms that contain Class B or Class C low-level waste.
The developments pertain to: t'a status of reviews of topical reports on waste stabilization media and high integrity containers; the results of the Workshop on Cement Stabilization of Low-Level Waste hela in Gaithersburg, MD on May 31 to June 2,1989; the identification of constituents that create problems with cement solidification of lw -level wastes, and; the notification to the NRC of mishaps with waste stabilization.
It is expected that addressees will review the information for applicability to their facilities and consider actions, as appropriate, to avoid problems in solidification of wastes in cement and in disposing of certain waste streams.
Addressees are encouraged to distribute the notice to responsible radiological staff and waste handling personnel.
However, suggestions contained. in this information notice do not constitute NRC requirements; therefore, no specific action or written response is required.
Discussion:
Update on Waste Form and High Integrity Cor,tainer Topical Report Review Status -
In Information Notice No. 89-27, " Limitations on the Use of Waste Forms and High Integrity Containers for the Disposal of Low-Level Radioactive Waste,"
March 8, 1989, it is pointed out that waste generators are required under 10 CFR 20.311 to certify that any Class B or C wastes that they send for disposal are structurally stable in accordance with 10 CrR Part 61.
The Information Notice goes on to describe the review of topical reports (TR) by the NRC on waste solidification media and high integrity containers for the disposal of class 8 or Class C wastes.
The status of these TR reviews by the NRC is summarized, and a description is provided on the implementat1on of NRC decisions
i IN 90-xx January xx,1990 page 2 of 4 on the TR by the Agreement State authorities that host the three operating low-level waste disposal facilities.
The Information Notice states that the 1
status of approved waste stabilization media and high integrity containers will change periodically as TR reviews are completed and as new TRs are submitted for review.
The Information Notice states that the NRC will periodically issue updates of the status of topical report reviews to keep licensees fully informed of approved solidification media and high integrity containers for disposal of Class B and C wastes. Attachment 1 provides the status of topical report reviews by the NRC as of January 1,1990.
Licensees are directed to Information Notice 89-27 for further information that applies to disposal of Class B and C wastes. Waste generators are urged to contact the disposal facility operators for additional information and procedural details prior to pursuing disposal options for Class B and C wastes.
Cement Solidification Workshop -
Information Notice 89-27 pointed out that no topical reports describing commercial cement stabilization of low-level wastes had been approved by the NRC.
Thissituationstillexists(SeeAtttchment1).
To gather information that would provide en improved understanding of the complex technical concerns in the use of cement for waste stabilization and that would lead to both short-term and long-term regulatory resolution of TR reviews on cement stabilization media, the NRC hosted the Workshop on Cement Stabilization of Low-Level Radioactive Waste on May 31 - June 2, 1989. During the Workshop the following topics were discussed:
lessons learned from small-and full-scale waste forms and observations at nuclear power plants; implications of laboratory test experience with cement solidification and the application to problem waste streams; stabilized waste form testing guidance (including the NRC's 1983 Technical Position on Waste form), and process control programs and waste characterization.
The results of the Workshop have been published as an NRC Conference Proceedings report, NUREG/CP-0103.
Licensees are encouraged to obtain a copy of this report and determine if any topics l
discussed will potentially improve their application of waste solidification processes.
Waste Constituents That Create Problems with Cement Solidification -
i One important concern.that licensees should be fully aware of which was discussed in detail during the Workshop is continuing concerns with deleterious chemical reactions ciuring waste solidification using cement.
This subject was first brought to the attention of licensees by Information Notice No. 88-08,
.i i
March 14, 1988, " Chemical Reactions with Radioactive Waste Solidification U
l Agents." As a result of the continuing concerns with this subject, the NRC has H
developed the attached list (Attachment 2) of waste constituents that could L
cause problems with solidification campaigns, particularly at nuclear power plants. The first part of the list identifies " problem" constituents of wastes that are expected ingredients in certain waste streams.
Licensees should ensure that proper formulations are being used for these types of wastes, especially if the wastes require structural stability.
The second part of the list are
" problem" constituents of waste streams that are not expected ingredients in I-the wastes, and may cause a problem with cement sM idification if they accidently I
get into a waste stream, especially since the waste processing vendor may not necessarily be using a. formulation that would successfully treat the waste
6
,s'?
IN 90-xx January xx,1990 Page 3 of 4 stream.
Sone of these constituents may be a problem for successful cement solidification even at parts per million concentrations, depending on the waste stream they are in and the synergistic offects that could arise.
The NHC has Identified these as waste constituents that could be controlled and possibly prevented from entering waste streams with good housekeeping, inventory control, use limits, or pretreatment, thereby minimizing the potential to af fect cenent solidification.
The NRC encourages licensees to determine if they are using any of these items, and if they are to determine if housakeeping, inventory, or use controls are adequate to prevent these " problem constituents from entering waste streams that ere to be solidified, especially waste streams that require structural stability.
Licensees who are aware of having small concentrations of these " problem" constituents in their waste streams, and are using a proper solidification formula to treat the wastes, should be aware that changes in concentrations of these constituents may result in a problem.
Licensees are also encouraged to evaluate the use of alternative products or chemical constituents in order to reduce or eliminate the possibility of " problem" constituents entering the waste stream. Licensees should inform solidification vendors of circumstances that may result in waste constituent changes so that the vendor may determine the correct formula to use in solidification.
This will help in avoiding problems such as those reported in Information Notice No. 88-08.
Licensees should be aware that several of the waste constituents listed in may result in a situation that produces mixed hazardous and radioactive waste.
The currently operating low-level radioactive waste disposal facilities are not permitted to receive mixed wastes.
Licensees should contact the Environmental Protection Agency (EPA) for more information on what constitutes a mixed hazardous and radioactive waste and refer to the joint NRC/ EPA guidance document entitled, " Guidance on the Definition and Identification of Consnercial Mixed Low-Level Radioactive and Hazardous Waste and Answers to Anticipated Questions."
Notification of Waste Stabilization Mishaps -
l The NRC has become increasingly concerned about mishaps that have occurred during the solidification of low-level radwaste at power plants and other facilities. These mishaps, some of which were described in Information Notice No. 89-27, have included waste forms that have failed to solidify completely and that swelled and/or disintegrated over relatively short tines af.er solidification.
These mishaps result in questions as to whether the waste form will satisfy the Part 61 stability requirements.
In order to maintain current information about problems encountered in solidifying wastes and placing wastes in high integrity containers for structural stability, the NRC will be asking waste processing vendors at the time the processor's TR is approved to volunteer to report mishaps like the ones iiescribed a'oove.
The NRC will be asking the vendor to report such mishaps to the Director of the Division of Low-Level Waste Management and Decommissioning within 30 days of the incident, i
Licensees will become involved in the reporting process to the extent that th?
waste that is involved in the mishap that is voluntarily reported to the NRC is the ultimate responsibility of the waste generator.
Licensees are encouraged to become familiar with the waste processor's reporting procedures.
