REQUEST FCR REVIEW OF THE WESTINGHOUSE TOPICAL REPORT ON FUtl REACTOR COOLANT SYSTEM CHEMICAL DECONTAMINATION The purpose of.this memorandum is to provide the generic discussion you requested on the requirements of 10 CFF Part 61 and the associated Branch Techr.ical Position on Waste Form (TP) as it relates to the certification for burial of radioactive waste generated in the Rear. tor Coolant System (RCS) decontamination process which is being proposed for use by the Westinghouse Corporation, lhe " Licensing Requirements for the Land Disposal of Radioactive Waste,"
10 CFR Part 61, contains the applicable regulatory requirements for low-level waste disposal. Hors specifically, 10 CFR 61.5S and 61.55 contain the waste-l classification and waste characteristics requirements applicole to waste generators.
These waste generator requirements help to assure that the disposal site will achieve and maintain its long-term stability as required by the performance objective in 10 CFR 61.44.
The Westinghouse Corporation Topical Report (TR) entitled. " Dilute Chemical Decontamination of the Full Primary Systein of a BWR Using the LOMI Process,"
contains projections of the quantities, chemical characteristics, and
, adiological and physical form of decontamination products generated in a full reactor coolant system decontamination.
In addition, the TR specifies i
that reactor coolant resin will be shipped to both the Barnwell Disposal Facility and the Richland Washington Disposal Facility.
The TR states that resin waste requiring stabilization following decon operations (Class A stable, Class B and. Class C stable) will be packaged.in either-high-integrity containers or solidified in cement. We would like to point out that the TP and the new appendix to this IP (enclosed) provides guidance on acceptable methods to meet the stability requirements of 10 CFR Part 61. At the present time, NRC has not granted a certification for a process to dispose of decontamination resln waste at any of the three operating disposal sites and the complete crittria necessary for proper disposal of this unique waste may not be centained in the TP on waste form.

f The TP emphasizes the importance of characterizing each particular waste s
stream which will be prcduced in the decontamination operations.
For the Westinghouse full reactor coolant system decontamination wastes, the vendor will need to identify the entire range of waste constituents.and elemental concentrations and determine if and hcw they will affect the ability of the proposed solidification formulations and the selected high integrity containers to meet the stability requirements over the long term.
In addition, Westinghouse proposes to seek approval for a wide range of waste streain types and with varying chemical compositions (including Boiling Water and Pressurized Water Reactor coolant decontamination resins).
The vendor's TR should focus on the results of the sampling data submitted to characterize each individual waste stream and test data sufficient to show that these generic compositions will meet the stability requirements of 10 CFR Part 61 and the TP on waste form. As explained in our memorandum to W. Bateman (Acting Branch Chief, Materials and Chemical Engineering Branch) on July 20, 1992, the NRC cannot begin a meaningfu'l review of the TR until testing equivalent to that. specified in the TP has been completed by the vendor and the vendor has concluded that the proposed waste formulations will meet the intent of 10 LFR Part 61.
If you have any further questions regarding this me u randum, please contact me at 504-2553 or Roy Perse'i of my staff at 504-2575.

lTh'e'TP emphasizes the importance.of characterizing each-particular waster stream which will be produced =in the' decontamination' operations.
For the i
Westinghouse full reactor coolant system decontamination wastes, this means identifying the entire range of waste constituents and elemental' concentrations which will affect the ability of the proposed solidification -
formulations and the selected high integrity. containers to meet the stability i
requireqents over the long term.
At the present time, NRC has not granted _a certificqtion for a process to dispose of decontamination resin waste _at any of the thyee operating disposal sites and the complete criteria necessary for-proper dis osal of this unique waste may not be contained in the TP on waste form.
In a dition, Westinghouse proposes to seek approval for a wide. range of waste stream types and with varying chemical compositions (including Boiling l
Water and Pre surized Water Reactor coolant decontamination resins).
. Review of this TR wil focus on the results of the sampling data submitted to characterize ea h individual waste stream and test data sufficient to show-that these gene ic. compositions will meet the stability requirements of_10 CFR L
Part 61 and the
'P on waste form. As explained in our memorandum to W. Bateman (Actin Branch Chief, Materials and Chemical Engineering Branch) on July 20, 1992, NR can not begin a meaningful review of your TR-until testing equivalent to that pecified in the TP has been submitted.
If you have any furt.r questions regarding this memorandum, please-contact Roy F rson of my staf at 504-2575.
