-volume reduced liquid is returned to the waste tank farm (SD-2).

UNACCEPTABLE EVENTS: 1. Failure of the STS to produce a decontamination faceor of 1000 for Cs-137.

APPLICABII.ITY L:

> Requirement No. 1 applies to the maximum concentration of Cs 137 permitted in the

' discharge of the final ion exchange column in the STS. Requirement No. 2 applies ,

to the maximum Cs 137 concentration permitted in the transfer of decontaminated.

.supernatant from~8D-3 to the LWTS. Requirement No. 4 applies to liquid that is sent to LWTS for volume reduction and is ultimately returned to the WTF.

L OEJECTIVE

> To provide a means to monitor the decontamination factor for Cs-137 prw'ded by the STS system and to assure that supernatant transferred eventually to CSS is decontaminated by a factor of at least 1,000 for Cs-137.

> ' DEFINITIONS 1

> STS processes three kinds of liquid.

> 1. Decontaminated Supernatant - liquid from Tank 8D-2 (either diluted or undiluted) that has passed through the STS ion exchange system.

> 2. Decontaminated Supernatant plus Flush - a final process step for STS operation which uses liquid from Tank 8D-1, or water, to push residual supernatant through the ion exchange columns. Typically 10,000 gallons-of Tank 8D-l' liquid or 6,000 gallons of water is used to flush the columns.

> 3. Liquid from Tank 8D water condensed from vapor generated in Tank 8D-2 and water generated from various STS operations. This 11guid has a relatively low salt concentration and a constan::1y increasing cesium concentration (as loaded zeolite is dun;-d to Tank 8D-1).

1 The STS was designed to provide a supernatant decontamination factor of at least 1,000 for Cs-137._ Technical requirement No. 2 gives the maximum acceptable Cesium concentration in Tank 8D-3 based on a DF of 1,000 from Tank 8D 2 L supernatant. This requirement sets STS product quality by placing a cesium limit, which is based on the weight frae. tion of the product, therefore ensuring an acceptable final product at CSS. DF calculatior.s for supernatant shall be based on samples of Tank 8D-3 and tank D-001, and-are used to verify STC system DF. Decontaminated supernatant with a decontamination facror less than 1,000 as -

measured at Tank 8D 3 will be recycled to Tank BD-2 for rework. Transfers from Tank 8D-3 to UWTS containing flush water shall meet the conditions of requirement No. 2 of this Technical Requirement, but the system DF calculation,-as described above, is not used for the transfer. Due to the changing feed concentrations, it is not possible to get a representative system DF while using flush water.

> Volume reduction of Tank 8D-1 liquid may be required as an emergency response to a leak in the waste tank farm. LWTS is capable of performing this volume reduction, to an activity limit of 50 pCi/mL (UWTS Design Criteria, WVNS-DC-025, paragraph 2.2.1). WVNS will work to the design criteria limit because of the emergency nature of this action. Decontamination factor calculations and process control calculations dasigned to limit the activity concentration of waste sent to the CSS should not be applied to liquid that will be returned to the high-level waste storage tanks.
