RDW 3.1 Page 2 3.6 It is the responsibility of cognizant supervision to assure that personnel filling packages of solid or solidified wastes obtain a waste permit number for each package.

3.7 It is the responsibility of the Duty Shift Superintendent or his designate, to initiate the preparation of a Waste Permit Form (CHP-16) for each package of solid or solidified radioactive wastes.

e 4.0 SOLID RADIOACTIVE WASTE 4.1 Solid radioactive waste containers, properly designated, are located at convenient points throughout the controlled zone.

Containers for compressible scrap should be lined with a plastic bag to prevent the spread of contamination during the transfer from the container to the baler.

4.2 Containers should be routinely monitored and radiological hazards posted as appropriate.

4.3 When full, containers should be emptied or processed for shipment as

( appropriate.

j 4.4 Large solid radioactive waste articles shall be monitored and then

wrapped, boxed, or otherwise sealed, if necessary, to confine any l contamination before moving or storing as contaminated waste.

4.5 CHP will assure that solid waste is properly packaged and shipped to 4

a licensed disposal site.

l 4.6 Solid waste will have no free standing liquids in the package. Use nf

absorbents, solidification agents or dewatering methods will be used as appropriate.

See Attachment 1 for the procedure to order the proper type of l

cement for solidification and absorbent purposes.

5.0 LIQUID RADIOACTIVE WASTE

[

5.1 All normal liquid radioactive wastes are collected by the waste disposal system and processed as required.

5.2 Prior to disposal of any tank of liquid radioactive waste, a sample of the tank shall be analyzed. The specific activity (in pCi/ml)

( shall be determined; isotopic concentrations identified, if necessary, and the required dilution factor calculated.

(

RDW 3.1 Page 3 5.3 If the tank is acceptable for disposal, a permit for radioactive waste discharge will be completed by a CHP Supervisor or his designated personnel and forwarded to the Duty Shift Superintendent who will authorize and carry out the disposal. Radioactive liquid waste having concentrations in excess of those specified in Appendix B, Table II, 10 CFR 20, after in plant dilution, will not normally be approved for discharge from the plant. A release rate in excess of that stipulated by the radioactive waste release permit is not i

permitted. Any deviation from the conditions of the release permit shall be noted on the permit.

5.4 Any uncontrolled, or unplanned liquid release shall be recorded and concentrations and total activity output will be determined by CHP.

The Duty Shift Superintendent and the Duty & Call Superintendent will be notified promptly.

6.0 GASEOUS RADIOACTIVE WASTE 6.1 All radioactive gaseous wastes emitted through the plant vent or 4

drumming area vent stack are monitored prior to the point of discharge.

f 6.2 The controlled release of all radioactive gaseous waste shall be in accordance with applicable Federal and State regulations and provisions

of the facility license.

6.3 Prior to disposal of any tank of gaseous radioactive waste, a sample of the tank shall be analyzed. The specific activity (in pCi/cc) will be determined; isotopic concentrations identified, if necessary, and the required dilution factor calculated.

4 6.4 If the tank is acceptable for disposal, a permit for radioactive 2

waste discharge will be completed by a CHP Supervisor or his

designated personnel ard forwarded to the Duty Shift Superintendent who will authorize and carry out the disposal.

i 6.5 Any uncontrolled, or unplanned gaseous release shall be recorded and concentrations and total activity output will be determined by CHP.

The Duty Shift Superintendent and the Duty & Call Superintendent will be notified promptir.

7.0 BURIAL SITE CRITERIA l PBNP primarily ships its radioactive vaste to the Chem Nuclear and U.S.

Ecology burial sites at Barnwell, SC and Richland, WA, respectively. The

, facilities are governed by different Agreement State licenses and therefore, their operations may differ from one another in certain areas.

! Prior to processing or shipping radwaste to either site therefore,

'( requires a review of the particular requirements at each facility.

l RDW 3.1 l Page 4 7.1 Chen Nuclear, Barnwell SC 7.1.1 Chelating Agents Waste sent to the Chem Nuclear burial site may not contain chelating agents with concentrations greater than 8% by weight. Waste with chelating agents within the range of 0.1 to 8.0% by weight must be solidified. The concentration limits apply to the vastes prior to solidification; dilution by solidification media is not allowable. This means that solidification media such as cement may not be added to the waste merely to lower the concentration of the chelating agents.

In addition, as is required by RDW 5.8, Paragraph 5, the concentration of chelating agents over 0.1% by weight must be listed on Form CNS-201, Barnwell Management Facility Radioactive Shipment Record.

7.1.2 Resins and Filters

( Ion exchange resin and filter media containing isotopes with greater than 5 year half-lives having a specific activity of all these isotopes of 1 pci/cm3 or greater must be stabilized by solidification. The waste when solidified may contain no significant free standing water, i.e., 50.5%

by volume. In lieu of solidification however, the waste may be disposed of in a high integrity container.

7.1.3 Incore Detectors Incore detectors containing transuranic materials are not acceptable for disposal at the Chem Nuclear burial site.

7.2 U.S. Ecology, Richland, WA 7.2.1 Chelating Agents There is no limit on the amount of chelating agents that may be contained in a package sent to U.S. Ecology. As is {

required by RDW 5.8, Paragraph 4 however, the concentration 8 of chelating agents over 0.1 percent.by weight must be listed on the U.S. Ecology Radioactive Waste Shipment &

Disposal Manifest. .

o RDW 3.1 i Page 5 7.2.2 Resins and Filters Ion exchange resin and filter media ccntaining isotopes with a total specific activity of 1 pCi/cm3 or greater and half-lives greater than 5 years must be stabilized by solidification. The waste, when solidified may contain no significant free standing water, i.e. 50.5% by volume. In lieu of solidification, the waste may be disposed of in high integrity containers which have been approved by the State of Washington.

7.2.3 Incore Detectors Incore detectors and other equipment contaminated with transuranic nuclides (TRU's) are acceptable for burial at US Ecology provided the concentration of TRU's is less than 10 nanocuries per gram of waste.

7.2.4 Special Nuclear Material No package containing special nuclear material for disposal may contain more than 100 grams of uranium-235, 60 grams of uranium-233, or 60 grams of plutonium. Waste containing a combination of these isotopes must be such that the sum of the ratios does not exceed unity; i.e. ,

Grams Contained U-235 , Grams Contained U-233 , Grams Contained Pu $1.

100 60 60 In addition, the radioactive shipment record used to describe the special nuclear material must be certified by the shipper to show compliance with USNRC Special Nuclear Material License No. 16-19204-01 (US NRC SNM No.

16-19204-01, Paragraph 20.)
