%*****/SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION PUBLIC SERVICE ELECTRIC AND GAS COMPANY HOPE CREEK GENERATING STATION DOCKET NO. 50-354

1.0 INTRODUCTION

In its letter dated November 25, 1986, Public Service Electric and Gas Company provided a revision to the Process Control Program (" Process Control Program, Revision 1", dated November 1986) for the Hope Creek Generating Station. The revised Process Control Program (PCP), in addition to addressing Class A wastes, addresses Class B and C wastes by incorporating the results of the Waste Chem Corporation testing performance program. The intent of this program was to demonstrate the compliance of the asphalt binder waste form with the requirements of 10 CFR Part 61.

This program is under staff review. In addition to requesting that the NRC review and approve the PCP, the licensee also requested that the NRC approve the use of a temporary radwaste solidification vendor (Chem-Nuclear Systems, Inc.) to process radwaste at Hope Creek.

2.0 EVALUATION In March 1983, the staff reviewed and accepted the Chem-Nuclear Mobile Cement Solidification System Topical Report (CNSI-2, 4313-01354-01, Revision 2) dated January 1983, for referencing in license applications and amendments. We have reviewed the revised Hope Creek PCP and find that it provides the required interface information, acceptable administrative controls, and adequate area (i.e., in terms of suitable location and suffi-cient space) for the temporary vendor's (Chem-Nuclear) equipment. Therefore, we find that the use of the temporary radwaste solidification vendor is acceptable.

In the Hope Creek Safety Evaluation Report (NUREG-1048, dated October 1984),

the staff concluded that the Hope Creek Solid Waste Management System, pro-vided by Waste Chem, Inc. (formerly Werner and Pfleiderer) and described in Werner and Pfleiderer Topical Report, WPC-VRS-1, "Radwaste Volume Reduction and Solidification System", is acceptable. In April 1978, the staff re-viewed and accepted the Werner and Pfleiderer Topical Report for referencing in license application and amendments.

I The Waste Chem System installed at Hope Creek utilizes an extruder /evap- j orator to provide volume reduction by evaporation and mixes the residual l with an asphalt (bitumen) binder. In August 1986, the state of South I Carolina, Department of Health and Environmental Control, issued a license  !

amendment to the Barnwell Waste Management Facility (Radioactive Material  !

License No. 097) permitting the facility to receive oxidized bitumen l (asphalt) solidified radwaste for disposal.

We find the operation of the installed Waste Chem System, which uses an asphalt (oxidized bitumen) binder to produce free-standing monolithic product, is acceptable on an interim basis. The interim basis will be in effect until the staff completes its review of the Waste Chem Topical Report "10 CFR 61 Waste Form Conformance Program for Solidified Process Waste Produced by a Waste Chem Corporation Volume Reduction and Solid-ification System" dated May 1986. The staff's preliminary review indicates that the topical report, for the most part, contains sufficient information for conducting a detailed and final review. We anticipate the completion of our review by September 1987.

We also expect that the NRC guidelines for the preparation and use of a PCP will be available for all licensees in early 1988. PSE8G should up-date and/or revise the Hope Creek PCP accordingly, when NRC guidance becomes available.

3.0 CONCLUSION

On the basis of the above evaluation, we conclude that the use of the temporary radwaste solidification vendor (Chem-Nuclear, Inc.) is accept- ,

4 able, and the use of the installed solid radwaste system at Hope Creek is l 4 acceptable for processing Class B and C solid wastes on an interim basis. l i The revised Hope Creek PCP is acceptable on an interim basis. The interim basis will be in effect until the staff completes the review of the Waste Chem Topical Report.
