2.0 Purpose The purpose thit 9reoperational inspection was to determine if the licensee's radioactive effluent control programs were consistent with regulatory requirements and commitments made in the Final Safety Analysis Report (FSAR) with respect to the following areas.
o Solid Radioactive Waste Program o Liquid Radioactive Effluent Control Program o Gaseous Radioactive Effluent Control Program 3.0 Status of Previously Identified Item
.
Closed) Inspector Followup Item (352 88-05-01; 353/88-03-01): TLD rogram conducted by a contractor should be audited by the Quality Assurance (QA) Group annually. The licensee updated the Annual QA Audit Checklist to include the contractor's TLD program. The inspector reviewed the QA Audit Report (Audit Number D-228, conducted on September 27-28,
<
1988) and noted that the contractor's TLD Program was audited thoroughly.
This item is closed.

Unit I facility. Equipment in place was designed for a two-reactor site,
^
and thus no additional mechanical systems were needed or planned by the licensee. The radwaste program was previously inspected in Nuvember, i
1988 (Inspection Report 50-352/88-23) with no violations noted.

4.1 Personnel i
The Operations Department staffs the Radwaste Control Room and Operations Supervisor. pulations, under the direction of the Radwaste performs all valve mani This Supervisor reports to both the Shift Supervisor and the Senior Engineer-Radwaste Packages are surveyed and wipe tested by members of the Health Physics staff. Classification, documentation and labeling of packages is the responsibility of the Supervisory Physicist-Radwaste Services.
Staffing levels within Radwaste Services and Operations (for the Radwaste Control Room)
appeared adequate for the level of operations expected for a two-unit facility.
4.2 Processes The licensee currently generates spent resin, contaminated tools and materials, laundry and Dry Active Wastes (DAW).
Spent resins are
, utilizing processed by dewatering in the High Level Storage Area (HLSA)d equipment a vendor supplied and operated system.
Contaminated tools an are cleaned on site both by the licensee and via a vendor-operated mobile decontamination unit, or are shipped to a vendor facility for decontamination.
Laundry is sorted by the licensee, with contaminated laundry cleaned by a vendor off site.
DAW is segregated into " clean" and " hot", then all material is sent to a vendor facility for verification and disposal.
4.3 Facilities Under present utilization conditions, the HLSA mhy have to be modified and/or procedures amended to accommodate the startup of Unit 2.
Presently the licensee has eleven large storage pits available for the dewatering and storage of radwaste liners. Six of these pits are typically in use at any one time, with the empty pits used for empty liner storage or as a reserve area. The Unit 2 startup can be expected to double the volume of spent resins generated at the facility, and thus may cause all the pits in the HLSA to be filled, with no reserve space available. The licensee was aware of this potential restraint and was formulating plans to address this, including reducing the storage time of filled liners in the HLSA prior to shipping.
5.0 Liquid Radwaste Systems Batch releases of liquid wastes are handled through the Radwaste Control Room. Releases are approved by the Shift Supervisor, with both Chemistry

and Health rhysics providing technical support. Staffing levels within these departments appeared adequate to handle the additional work generated by the operation of Unit 2.
5.1 Process Radiation Monitoring j
The licensee's liquid process rad Stion monitors (Process Radiation consist of the Service Water monitors, Reactor Monitoring System) Water monitors and the Residual Heat Removal Enclosure Cooling Service Water monitors. Monitors utilized in Unit 2 are of the same design as those currently in use at Unit 1.
Preoperational testing of these conitors has been completed in accordance with Procedure 2P-79.20, Rev 0," Liquid Process Radiation Monitoring System Startup Subsystem 79E".
Documentation associated with this testing included Test Change Notices and a Test Exception Log. Calibration of the monitors was also included as part of this preoperational testing procedure.
The inspector reviewed Procedure ST-2-009-600-0, " Radioactive Liquid Effluent Monitoring-Cooling Tower Blowdown Discharge Line Flow Calibration / Functional Test. This test was cc,mpleted satisfactorily on March 24, 1989.
5.2 Effluent Releases Sampling and analysis of liquid effluents prior to batch release are the responsibility of the Chemistry Department.
Discharge permits are initiated by Operations in accordance with Procedure CH-1017, Rev 10,
" Procedure for Preparation and Control of Liquid Rad Waste Discharge Permits". Offsite dose calculations for each release were performed by the Health Physics staff which also prepared monthly release summaries and the semiannual effluent release reports.
