I.I PROCESS PARAf'1ETERS Naste can be solidified usino the PNSI sclidification -Unit and Envirostone in accordance with the formulas listed in this PCP.

Soeciiic waste conditioners are required ior some 'waste forms before solidification. The procedures for solidification of various wastes are included as separate addendums to this procedure.

if the laboratory -analysis of the waste solidification shows the waste setup time will be less than desired, Rcd Top Retarder can be added in smail amounts to e tend thE setup time o long enouah to ensure that the full volume of Envirostone can be thor oughly blended wi th the waste to f orm a homogeneous mi xture.

1.2 The PNSI operator shall ensure that a Radiological Work Permit has been issued for the performance of the sample verification activity and that adequate person-nel monitoring and radiation detection equipment is on hand.

The PNSI operator shal 1 ensure that al 1 necessary ma-terials and equipment are on hand prior to beginning the sample verification. Suggested equipment and mater-ials for the test are as listed below:

6 =-00 to 500 ml plastic beakers 6 mixing spatulas

] - 500 gram capacity scale 20g PNS waste conditioner WC-785 50g - Calcium Hydroxide 1000 g Envirostone NOTE: The waste and chemicals used to solidify the sample waste must be from the same containers or lot numbers to be used in the full seal e sol idi f ication,

].4 A one-liter sample shall be taken for solidification in the laboratory for each separate batch of waste to be processed. The operator may choose to take the samples from the storage tanks to be solidified in the liner, or may take the sample from the liner directly, after the waste has been transf erred to the liner. Due to the importance of obtaining a representative sample for use in the verification procedure, the operator shall confirm that the contents of the waste f orm to be solidified have been adequately mixed and that, the sample is a part of a homogeneously mixed waste batch.

2 0 SAMPLE VERIFICATION

2. 1 Record the information obtained during sample verifica-tion on the Sample Verification Worksheet.

Provide a waste sample (si "e to be specified by the plant) to the plant staff for isotopic analysis.

Place a sample of the waste in the beaker so that the resins are at the 200 ml level with the liquid solution iust covering the resins. This may necessitate pouring off some of the liquid solution.
