4.0 Transportation and Solid Radwaste In accordance with plant procedures, preparation, packaging and transportation of wastes are the responsibility of the Hazardous Waste Coordinator, who reports to the Radiological Controls Supervisor.
The incumbent Hazardous Waste Coordinator has been in this position since May, 1989.
Wastes included spent resins, evaporator bottoms, filters and Dry Active Wastes (DAW).
4.1 Quality Assurance / Quality Control The Quality Assurance / Quality Control program at Maine Yankee involved Quality Assurance audits of inplant and principle vendor activities, Quality Control reports on selected radwaste activities, and Quality Control hold points and checklists to examine each shipment and major radwaste evolutions. Audit MY-89 09, dated August 24, 1989 was an evaluation of the licensee's Radwaste and Process Control Program. There was one deficiency and two observations identified in this audit, none having direct safety significance.
and corrective The deficiency was prom tly addressed by the licensee,ing of the actions were verified b Quality Assurance.
The audit radwaste area has signi icantly improved since the last NRC inspection in this area, conducted in December, 1988.
Audit 87-078, dated August 6, 1987, was conducted to evaluate which provided shipping Westinghouse /Hittman (now Westinghouse RS) tion services, identified casks, deficiencies, none of which involved significant safety issues.
waste solidification and transporta eight This audit was cor. ducted by the Yankee Atomic Electric Company on behalf of its affiliated member companies, including the licensee.
The Quality Program Department ((PD) ion had mandatory radioactiveconducted of radwaste activities and in acdit material shipment hold, points.
Evaluation d9E-003 was based upon the observation of a waste solidification conducted in February,1989.
One deficiency and 12 observations were noted, which related to plant specific procedures and procedural violations but which had no direct impact on the quality of the radwaste processed. Hold points for QPD review were documented for each shipment of radwaste.
This program of Quality Assurance and Control activities was determined to have significantly improved since the last NRC inspection in this area.
The inspector had no further questions in this area.

All records were found to be com)lete, and to accurately classify the material in accordance with 10 C;R 71 and 49 CFR Parts 100-179.
The inspector also observed the loading and shi> ment of a resin High Integrity Container 1189 191.
.icensee actions observed included inc(HIC), shipment shi) ping cask (a Hittman HN 100, Series III cask), port vehicle andloading of th oming inspection of the trans (NUilC Model 120) into the shipping cask, and the outgoing survey of the shipping cask and transport vehicle.
The licensee personnel involved in this evolution included representatives of the maintenance, operations, radiological controls and QPD departments.
This shipment was conducted in a highly professional manner, and no violations or deviations were observed.
,
In addition, the inspector reviewed the following transportation procedures.
9.1.14, Rev 12. " Receipt of Radioactive Material" 9.1.15, Rev 23, " Shipment of Radioactive Material" 9.1.18, Rev 11, " Receipt and Handling of New Reactor fuel" These procedures were determined to be complete and to accurately reflect current transportation operations.
4.3 Radwaste In accordance with plant procedures, liquids were processed through
,
the plant evaporator, and the evaporator bottoms were then solidified utilizing a Hittman procedure, or were processed through a DURATEK demineralization system.
Spent resins were sluiced to a High Integrity Container and dewatered by the licensee.
Spent filters were stored on site in shielded containers.
Uncompactable DAW was bulk loaded in B-88 containers or SeaVar s for shipment to Scientific

Ecology Group (SEG). Compactable DAW was com) acted by the licensee
'
in B-88 containers which were then sent to SEG for supercom l
Laundry was process,ed by Interstate Nuclear Services (INS). paction.
'
The inspector reviewed the following procedures related to radwaste.
9.1.13, Rev 3. " Transfer and Storage of Radioactive Waste Containers in the Low Level Waste and Equipment Temporary Storage Building" l
9.1.21, Rev 3, " Preparation of Radioactive Solid Waste for Disposal" 9.1.29, Rev 2, " Quality Control for Radioactive Waste Program" 1.18.4, Rev 6, " Spent Resin Storage and Processing".
These procedures were determined to be complete and to accurately
+
reflect current transportation operations.
The inspector examined the radwaste storage bunker and discussed with
the licensee staff the concerns raised during a previous NRC inspection (50 309/89-15). The sump pump for the bunker was repaired and was found to be operational at the time of this
inspection, however no surveillance system had been established to verify sump pump operability. Material in the bunker included three
.
>
small HICs, which the licensee indicated were to be shipped for i
burial during the week of November 20 1989, a neutron source in a long shielded pipe, and several miscellaneous contaminated items L
wrapped in Herculite. All items were on pieces of lumber which
'
)revented them from coming into. contact with the floor of the bunker.
_icensee personnel indicated that utilization of the bunker would be limited in the future, with its principle use being temporary storage of HICs containing processed radwaste awaiting disposal.
'
Scaling factors for plant wastes were evaluated on an annual basis by Yankee Atomic Electric Company for all waste streams in accordance with plant procedures. This met the sampling criteria set forth in the NRC Branch Technical Position for Waste Classification.
The licensee has made two significant improvements in the radwaste
'
area, in the calculation of transport and waste classification.
These were the purchase and utilization of the RADMAN computer code for the calculation of waste and transport classification, and the requirement for the Radiological Controls Supervisor to review all shipping paperwork prior to the transport vehicle leaving the Maine Yankee site.
The inspector had no further questions in this area.

4.4 Training
-
'
Training in the areas of transportation and radwaste was presented to Radiological Controls Technicians on an annual basis. This training i
program consisted of the presentation of one course per year from those listed below.
RP-SRM 02, "Radwaste Shipping Preparation'
'
RP-SRM-03, "Radwaste Transport Vehicle" RP-SRM-04, " Labelling, Marking and Classification"
'
Additionally, the Hazardous Waste Coordinator and the Radiological
Controls Supervisor are given biennial training via a vendor supplied training course. This
)rogram was determined to meet the requirements of NRC IE 3ulletin 79-19 for the training of radwaste workers.
4.5 Interim Radwaste Storage The licensee has designed and constructed a Low Level Waste Storage Building located outside the Radiation Controlled Area of the plant.
This facllity has sufficient capacity to store all packaged radwaste
.
generated at Maine Yankee for five years or more, assuming current radwaste generation rates. This facility is currently in limited use, with DAW in B-88 boxes a solidified liner containing evaporator bottoms,contaminatedasphaltandsandin55-gallondrums, empty
!
'
HICs, and some outage equipment currently in storage. The inspector
-
had no further questions in this area.
