5.1.1 Arranging contractor for resin handling and transportation

( services. I 5.1.2 Securing a work area for resin transfer and packaging.

(This is normally the west end of the train bay).

5.1.3 Coordinating the various ANO Departmental functions.

NOTE: For the disposal of spent radioactive resins, the Radioactive I Waste coordinator is normally the supervisor in charge. .

5.2 The Health Physics Superintendent is responsible for providing an ade-quate number of Health Physics Technicians to provide radiological l

protection.

l 5.3 The Hechanical Maintenance Superintendent is responsible for providing -

an adequate number of Hechanical Maintenance personnel to provide main-tenance support.

6.1 An ALARA review has been completed, and an RWP has been issued.

6.2 A transportation cask or another shielded container is available to move the disposal container.

6.3 If applicable, sufficient contractor personnel have arrived and have been issued TLD's.

6.4 The work area has been lined with protective material.

6.5 The disposal container has been placed inside the shielded container.

6.6 The applicable Unit's Shift Supervisor has been notified that the pre-requisites have been completed and has given his permission to commence the werk.

7.0 INSTRUCTIONS ,

( NOTE: Unless specified, the following steps may be worked simultaneously.

7.1 Place the cask in the work area and wrap with protective covering to avoid contamination of the trailer or cask.

7.2 If necessary, realign the resin transfer hose to the appropriate con-nection as follows:

7.2.1 Health Physics shall set up the area in accordance with the ,

RWP and good radiological practices. Approximately one gallon l of water should be anticipated to leak out when the system is broken.

l Area Set Up Complete a Health Physics Technician l

7.3.2 Permission granted to raise hatch Unit one Shift Supervisor NOTE: This step is not applicable if the resin transfer is not being done in the Train Bay.

7.4 Complete contractor (if used) and radiological equipment setup in the

( work area.

7.5 Transfer the resin in accordance with the appropriate procedures listed in Section 3.2. Adequate precautions shall be taken in accordance with the RWP and Health Physics instruction to maintain exposures ALARA.

Secure resin transfer upon instructions from Health Physics or the Radio-active Waste Coordinator, or other involved personnel.

7.6 De-water the transferred resin in accordance with the applicable con- ,

tractors procedure as listed in Section 3.2.

l I NOTE: De-watering to be performed by contractor using contractors proce-

, dures and not by AP&L.

l l 7.7 Repeat Steps 7.5 and 7.6 until the required amount of resin has been l transferred.

7.8 Radiochemistry shall obtain and analyze a sample of the de-watered resin.
