PROCESS CONTROL PROGRAM MANUAL Revision:1 LAL C4-24-90 j or -i 1.0L PURPOSE During normal operation of the Point Beach Nuclear Plant, radioactive-materials are generated in the form of spent: resins, filter' sludge, ,

evaporator concentrates, and spent cartridge filter elements. These wastesL

' require processing in appropriate portions of the solid waste management

-system prior to-shipment offsite for disposal. Liquid wet wastes are -

either solidified or dewatered. Spent cartridge filters may be packaged' with suitable absorbers or solidified prior to' shipping. procedures and

practices are implemented to establish process parameters within which- ,

radwaste! systems are.to be operated. The procedures,and parameters providef assurance that proper waste form' characteristics are achieved.

z 2.0 PROGRAM ADMINISTRATION' 1he? primary respons'ibility for the beplementation of;the PBNP Process

' Control Program'and'any actions required by the program resides'with_the manager - PBNP'and the PBNP staff. Plant and vendor procedures used for; 1 the processing of radwaste shall'be reviewed and approved'in-accordance with-the_ applied 31efrequirements of QP and PBNP procedures.

The Nuclear Plant' Engineering and Regulation Section (NPERS).will provide technical, regulatory, and administrative support necessary to-fulfill the requirements of'the Process' Control Program.

^

3.0. REGULATORY REQUIREMENTS-Radioactive wastes ' generated at' Point Beach Nuclear' Plant shall be shipped' to a licensed. burial site for disposal in ~accordance with applicable

Nuclear Regulatory Commission, Department of Transportation, State, and burial site' regulations. .Waste containers, shipping casks, and packaging methods shall comply with epplicable l federal regu1 Ations.

Radioactive waste processing and handling activities shall'be conducted consistent with PBNP ALARA principles and practices.

r-

, Radioactive waste shipment from PBNP shall be suspended if the provisions of the~ Process Control Program are not satisfied.

' Y 74.0 SOLIDIFICATION j

The solidification of liquid wastes shall be' assured by.the implementation.

• of approved procedures. .The radioactive waste solidification program at-PBNP. shall be- conducted in accordance with the ' following provisions: . ,

4 .11 A-set of process parameters shall b'e established which provide' boundary conditions within which reasonable assurance'can be provided  ;

that waste solidification is accomplished. Typical process  ;

parameters include pH, oil content, water content, ratio of solidification _ agent to influent waste, and ratio of r.olidification

~

agent to chemical additives.

L I 4.2 Procedures shall prov'ide assurance that the solidification process lis ,

conducted within the established process parameters, i

4.3 Procedures'shall provide assurance that the' final waste product meets the appropriate waste characteristic requirements for-solidified -I wastes.

4.4- 1Rer,rds shall be maintained for individual solidification batches denonstrating conformance with established process parameters.

1,.-

-( 4.5. A solidification-test sampling program shall be utilized to verify K> the solidification of at least one representative test specimen from l,' every. tenth batch of,each type of liquid wet radioactive waste-(e.g.,1 p filter sludge, spent resin, evaporator bottoms, boric acid solution).

If a test specimen fails to solidify, further solidification activities'shall.be suspended-until'such time es additional test- 1 specimens ~can be obtained, alternate solidification parameters

detennined,> and a subsequent test verifies solidification. Process  !

control parameters shall be modified as required to. ensure proper solidification of, subsequent-batches.

L L

1 5.0. DEWATERING' Spent resins and filter sludges may be shipped for disposal as dewatered waste if acceptable to the receiving burial' site. The dewatering of

. radioactive waste.shall be assured by the implementation of approved <

' procedures. The radioactive waste dewatering program at PBNP shall be-

conducted in accordance with the following provisions

1 5.1- A set'.of process parameters shall be established to provide boundary 1 conditions within which reasonable assurance can be provided that i dewatering is accomplished. Typical process parameters include i settling time, drain time, and drying time.

. Containers (HICs)-approved by the specific burial sites which

~

y V 3 satisfy 10 CFR 61 waste form stability requirements shall be used, l

as appropriate.

O1 WASTE ~ CLASSIFICATION

{ f -650 N - .

The. waste classification program at PBNP shall comply with the provisions:

of 101CFR 20 and 10 CFR 61. H q

-. Waste classification requirements may be accomplished using a scaling factor l methodology. . The concentration of alpha and beta emitting _ .-

% , radionuclides!may be determined by indirect methods using scaling factors which.related the' inferred concentration of one'radionuclide to another-that is^ measured. Scaling factors shall be detennine'd from a1 sampling .

analysis program of radioactive waste streams. Waste streams will'

.[ s typically be- analyzed annually for the detennination of- scaling factors -

T unless' alternate sampling frequencies are warranted by available data.
