APPENDICES Appendix A-Schematic Flow Diagram Appendix B-Radwaste Cement Solidification System Diagram l I 0 1.0 PURPOSE The purpose of the Process Control Program (PCP)for the Palo Verde Nuclear Generating Station (PVNGS), Units 1, 2, and 3 is to establish a set of process parameters which will provide reasonable assurance of complete solidification of various liquid radioactive"wet wastes" including resin slurries, evaporator bottoms, filter sludges, and chemical drains in accordance with the requirements of applicable portions of the PVNGS Quality Assurance Program, PVNGS Technical Specifications, PVNGS Final Safety Analysis Report, Depart-ment of Transportation (DOT)regulations, Nuclear Regulatory Commission (NRC)regulations, and licensed burial facilities acceptance criteria for solidification, packaging, and ship-ment to an approved offsite burial site.There are no Arizona State Regulations applicable to PVNGS.Toward this purpose, the PCP ensures that the solidified substance is a monolith having no freestanding liquid and is within the limits as set forth in the above mentioned regulations and acceptance criteria.This PCP will also ensure that solidification'will be performed to maintain any potential radiation exposure to plant personnel to"as low as is reasonably achievable" (ALARA)levels, in accordance with the"ALARA Program" procedure.

2)Boric acid waste from the Boric Acid Concentrator.

3)Bead resin waste as a slurry from the Spent Resin Tanks.4)Chemical Drain Tank waste.5)Spent filter cartridges.

b.Typical and atypical wet waste types shall be identified by the"Solidification Process Control" procedure, which provides a record of waste formulations.

c~When the radiation level of a waste batch is determined to be excessive by ALARA standards, a waste substitute shall be prepared in accordance with the"Solidification Process Control".3.2 Process Parameters a~An acceptable waste product for transfer and disposal in accordance with 10 CFR 20.311 for class A, B, and C waste shall be provided by compliance with the"Solidification Process Control" procedure and the"Solidified Radioactive Waste Classification" procedure.

These documents establish boundary conditions to provide reasonable assurance that solidification will be complete.co For class-A waste types containing concentrations of chemicals that do not fall within the bound of chemical concentrations for which preoperational solidification tests have been performed by Hittman Nuclear and Develop-ment Corporation, acceptable base data for test solidifications shall be developed in accordance with the"Solidification Process Control" procedure.

d.As plant conditions dictate, including.ALARA considerations as well as inplant system inoperability due to maintenance, repairs, or modifications, a portable solidification system will be used to process class A waste in accordance with the vendor's operating procedures.

Class B and C waste will be processed in accordance with the vendor's operating procedures and a NRC approved 10 CFR 61 Topical Report.

0 e.For class-B'and class-C waste types, a 10 CFR 61 qualified solidification process will be used on the installed solid radwaste system in accordance with the"Solidifi-cation Process Control" procedure",or a portable solidification system will be used in accordance with the vendor's operating procedures and a NRC approved 10 CFR 61 Topical Report.f.Process mixing ratios for class-A, B, and C waste types shall be determined for each waste batch in accordance with the"Solidification Process Control" procedure.

3.3 Waste Classification a~The"Solidified Radioactive Waste Classification" procedure shall provide PWR scaling factors for identifying specific radionuclides as required by 10 CFR 61.55,"Waste Classification." b.Scaling factors shall be verified or updated annually by waste stream analysis to ensure acceptable standards are maintained for waste classification.

c.During incident conditions where the use of the existing scaling factors is questionable, the waste shall be classified by correlation factors or actual sample analysis in accordance with the"Solidified Radio-active Waste Classification" procedure.

3.4 Waste Preconditionin a.The"Operation of Solidification System" procedure shall designate the required mixing/recirculation times and system operations to ensure a representative sample is obtained after chemical addition and prior to process initiation.

b.Adjustment of the waste solution pH shall be in accordance with the"Operation of Solidification System" procedure.

c.The"Operation of Solidification System" procedure shall designate when heat tracing is required to ensure chemical suspension.

3.5 Verification of Solidification a~Solid Radwaste S stem 1)The solidification bench tests, in accordance with the Hittman Topical Report, Radwaste Solidification System (Cement), HN-R1109, Revision 4, provide the solidification bench testing base data for the"Solidification Process Control" procedure for use with'class-A type waste.

lf P 0 2)The solidification bench tests in, accordance with a vendor's NRC approved 10 CFR 61 Topical Report will provide the bench testing base data for the"Solidification Process Control" procedure for use with class-B and C type waste.3)During solidification system operations, additions'o the waste feed tank, waste feed pump operation, and process mixing ratio adjustments shall be in accordance with the"Operation of Solidification System" procedure.

i.No additions will be made to the waste feed tank while the tank is being recirculated for sampling or processing.

ii.The waste feed pump will not be stopped during sampling.4)A periodic solidification bench test shall be performed as specified by and in accordance with the"Solidification Process Control" procedure for verification of an acceptable solidification process.5)If any solidification bench test is found to be not acceptable, subsequent operations and testing shall, be in accordance with the"Solidification Process Control" procedure.
