{ Revision 1 01-11-84 STEAM GENERATOR SLUDGE LANCE FILTER DISPOSAL 1.0 GENERM.,

To ensure compliance with the numerous regulatory requirements for the packaging, shipment and disposal of radioactive waste, the following procedures will be utilized for disposing of steam generator sludge lance filters.

2.0 REFERENCES

2.1 Title 10, Code of Federal Regulations 2.2 Title 49, Code of Federal Regulations 2.3 Chem-Nuclear Barnwell Site Disposal Criteria Memo, dated December 8, 1978 3.0 RESPONSIBILITIES 3.1 Operations Group Responsibilities 3.1.1 Prepare an empty liner and place it at a convenient position by the sludge lance trailer for loading.

3.1.2 Place a sufficient amount of dry cement at the liner location for adding to the liner as the used fi]ters are loaded.

3.1.3 Dry cement should be covered with plastic to protect it from rain.

3.2 Westinghouse Sludge Lance Crew Responsibilities 3.2.1 The Westinghouse sludge lance supervisor will ensure that his personnel are familiar with and comply with this procedure.

3.2.2 The Westinghouse sludge lance supervisor will ensure that the sludge lance area is kept reasonably clean and will notify a Health Physics Supervisor of any condition that might result in the spread of radioactive contamination.

3.3 Health Physics Responsibilities 3.3.1 Ensure that all provisions of the radiation work permit are being observed.

( 3.3.2 Periodically monitor the filling of the lir.=r to ensure that the provisions of this procedure are complied with.

3.3.3 Obtain the necessary radioactive waste permit and identify the liner with the permit number.

3.3.4 Put two " Caution Radioactive Material" markings 180* apart on the liner.

NOTE: THESE LABELS WILL NOT EE NECESSARY IF THE LINER IS TO BE IMMEDIATELY SURVEYED AND MARKED " RADIOACTIVE LSA UN2912."

3.3.5 Prepare the liner for shipment.

3.4 Chemistry Responsibilities 3.4.1 Obtain two sludge samples from each steam generator.

3.4.2 Analyze the samples and forward results to the Nuclear Plant Specialist or Engineer assigned to radwaste.

4.0 SPECIAL PRECAUTIONS 4.1 No paper, plastic bags, cardboard boxes or other miscellaneous trash will be placed in the liner.

(

4.2 Filters are to be distributed in a manner that will allow maximum utilization of the liner and an even distribution of dry cement.

5.0 PROCEDURE .

5.1 Liner Preparation (Operations) 5.1.1 Place the liner at the sludge lance trailer in a convenient position for filling. Cover the top of the liner around the opening with plastic to protect against contaminating the liner.

5.1.2 Place a sufficient quantity of dry cement next to the liner.

This cement will be added as the liner is filled.

5.2 Liner Filling (Westinghouse) 5.2.1 Put 3 bags of cement in liner.

5.2.2 Filters to be disposed of will be placed into the liner in l evenly distributed layers.

l 5.2.3 Filters should be dewatered to the maximum extent practical

! before they are put in the liner.

.r oC RDW 3.5 Page 3 5.2.4 A record of the number of filters from each steam generator put in a liner, and gallons of sludge removed should be kept on CHP-137, Steam Generator Sludge Lance Filter Disposal Record. Send the completed form to the Superintendent - CHP.

5.2.5 After a layer of filters is placed in the liner (bottom area of liner covered), dry cement will be sprinkled over them to absorb residual moisture. This will be done after each layer of filters are placed in the liner. This layer of cement shall completely cover the' layer of filters.

~

5.2.6 When the liner is full, cover the top layer of filters with dry cement to a depth of one inch.

5.2.7 After the final layer of dry cement is placed in the liner, the top and sides are to be cleaned. After pleaning is completed, notify Health Physics so that the liner may be surveyed for loose radioactive contamination. No removable external contamination is allowed. Put a lid on the liner, but do not tighten the bolt.

5.3 Liner Preparation for Shipment (Health Physics) 5.3.1 Periodically monitor the radiation and removable contamination levels of the liner and insure that filling procedures are being complied with.

l 5.3.2 Obtain a waste permit (CHP-16) and number from the control room. Label the liner with the waste permit number for future identification.

5.3.3 After the liner is filled and cleaned, perform a radiation and removable contamination survey. Removable contamination

. must be less than minimum detectable.

5.3.4 Arrange to have the liner moved to the storage area and complete all necessary preparations for shipping.

5.4 Sludge Analysis (Chemistry) 5.4.1 Obtain two sludge samples from each steam generator.

One sample near beginning and one near end of sludge lancing sequence.

5.4.2 Analyze the sludge for isotopic concentration in pCi/cc of wet sludge.

( 5.4.3 Forward results to Nuclear Plant Specialist or Engineer assigned to radwaste.
