The inspector interviewed cognizent members of the radiation protection department and observed or reviewed the following solid radioactive waste management program activities:

• Waste stream sampling results and waste characterization documentation

= Scaling factors for required isotopes not measured directly

Solid radioactive waste classification

. Quantities of radioactive waste shipped for dispot.al

. Waste minimization program

= Annual radinactive effluent and so;id radioactive waste repons Observations andf1Dd1023 The inspeJtor verified that waste stream samples were taken as required and analyzed to meet 10 CFR Part 61 requirements for waste classification and characterization. Six waste streams wNe identified that consisted of dry active waste, resin, and filters. Each of the different waste media was divided into two waste streams. Waste stream samples were analyzed by a contractor laborator Classification of waste was performed with a computer code used in the nuclear industr Scaling factors for difficult to measure nuclides in the waste streams were determined and updated as needed in the radwaste computer code data base. Selected exampies of radioactive waste packaged for burial determined that the waste was properly classified and characterize The radwaste computer code used by the licensee was obsolete and no longer supported with current updates by the vendor. However, the radiation protection staff, through the use of several program applications maintained the ability to perform proper data analyses and process the required waste classification and transportation documentation. The licensee stated that arrangements to purchase a current computer code were being develope .. . .

The transfer of the resin went well and no problems were identifie Discussions on radwaste minimization efforts were held. The licensee showed good l performance in its efforts to reduce the amount of dry active wastes generated. Worker  !

awareness was enhanced to minimize radioactive waste and maintain contaminated areas to a minimum. Licensee data trends showed that these efforts were effective.

'

However, the licensee have reached a plateau in reducing radwaste generatio '

The volume of radwaste generation was tracked by the licensee with no segregation, processing, or volume reduction. Recently, the licensee began tracking the weight of wastes generated. The following table of licensee outage data shows the dry active waste generated per outage.

Audits and assessments of the solid radioactive waste management and transportation -

programs were reviewed. The review also included the following:

a interviews of quality assurance personnel

= Qualifications and resumes of auditors and technical specialists a Quality controlinspections

- Action requests Observations and Findinas Nuclear Quality Services Audit 95031 of radwaste activities was conducted September 19,1995, through July 25,1996. An audit of this area is conducted every 24 months in accordance with Technical Specification requirements.' The audit team included off site technical specialists knowledgeable in radioactive waste management and transportation activities. The inspector determined that the audit was comprehensive in its review of solid radioactive waste management and transportation activitie During the last NRC inspection, a concem was identified regarding the lack of a quality assurance, programmatic review of transportation activities. The licensee committed to a programmatic review of transportation activities to be included in the 1996 auality assurance audit of the solid radioactive waste ma..agement activitie The inspector verified that the commitment to enhance quality assurance oversight of transportation programs was implemented during the 1996 audit. The licensee also implemented quarterly assessments for a 2-year period. The quarterly assessments were an enhancement to program oversight since the last NRC inspection. Six assessment reports pertaining to solid radioactive waste and transportation activities were conducted in 1997. The assessments were effective in providing feedback to management on program effectivenes Auditi .r qualifications were reviewed, including resumes of technical specialists. The qualifications and experience of auditors was very good. Another concem raised during the last NRC inspection was that the individual responsible for conducting the majority of

,

the audit activities in radioactive waste management and transportation had little radiation protection experience. The inspector noted that the current quality assurance

. staff received training in radioactive waste transpodation and that the organization had acquired an individual who had extensive experience with the transportation of radioactive materials and radioactive waste processin . __ ._ - . _ . _ - - -
