USQ-HTF-2015-00706 Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4 Page 1 of 7
Title:
Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4 Proposed Activity:
The Proposed Activity (PA) is the use-as-is disposition of Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4.
Deviation
Description:
The Specification C-SPP-F-00055, Revision 4, Furnishing and Delivery of Tank Closure Grout, Section 3.2.1.2 Tank Closure Grout Mix, Item A.6 states the following:
The trial batching shall demonstrate the ability to meet the maximum bleed of 0.0 after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
Contrary to this requirement, several batches of grout used in filling Tank 16 were identified having bleed test results greater than the required 0.0%. The maximum value was 8.9%.
Bleeding is a form of segregation that refers to the process by which water comes out to (or up to) the surface of placed concrete as it cures. Because water typically has a lower specific gravity than all other ingredients in a concrete mixture.
The disposition of the SDDR Number 13307 is a one-time use-as-is deviation from the specification requirement.
Justification for Deviation:
The batches which exceeded the zero bleed requirements met all other performance requirements in the specification. In addition, the deviation does not invalidate the requirements of SRR-CWDA-2010-00128, Revision 1, Performance Assessment for the H-Area Tank Farm at the Savannah River Site.
The PA has a Functional Classification of General Services GS.
There are no interim configurations during the execution of this work that will adversely impact credited SSCs.

USQ-HTF-2015-00706 Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4 Page 4 of 7 DATR - System Acceptability Review The Proposed Activity (PA) is the use-as-is disposition of Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4. It was concluded the deviation did not compromise the grout quality or compromise the assumptions and inputs of SRR-CWDA-2010-00128 Performance Assessment for the H-Area Tank Farm at the Savannah River Site.
A USQS has been performed and found the PA to be acceptable. The Environmental Evaluation Checklists (EEC) LWO-H-2014-0013 Tank 16 Grouting is not impacted by the PA.
Tank 16 is identified in N-ESR-G-00001, High Level Waste Emergency Response Data and Waste Tank Data Table G-6 as a waste tank requiring a determination review for an Unreviewed Waste Management Question (UWMQ). With concurrence from C&WDA (e-mail attached), a UWMQ Applicability Determination was performed and an UWMQ Evaluation is not required. The PA is not a change to the waste stabilization formulation, because the PA does not compromise the assumptions or inputs of SRR-CWDA-2010-00128, Revision 1, Performance Assessment for the H-Area Tank Farm at the Savannah River Site or DOE/SRS-WD-2014-001, Revision 0, Basis for Section 3116 Determination for Closure of H-Tank Farm at the Savannah River Site The implementation of the PA will not have an adverse impact to the facility or its associated systems.
Screening Questions:
Is the Proposed Activity a change to TSRs or JCO controls?
Justification:
S-TSR-G-00001 Concentration, Storage, and Transfer Facilities Technical Safety Requirements was reviewed. The section 1.6 (Modes-CLOSURE) and Administrative Controls 5.8.2.8 (Configuration Management Program), and 5.8.2.43 (Prohibited Operations) were applicable. Tank 16 is defined as a non-process area and an inactive location. There are no LCO controls associated with Tank 16. The PA complies with the Administrative Controls stated above as it implements the Configuration Management Program and it does not involve a Prohibited Operation. This PA does not change the TSRs.
There are no JCOs associated with CSTF.
Does the Proposed Activity permanently eliminate a DID/ITS or Degrade its safety Function as explicitly described on the Safety Basis?
Justification:
Reviewed the CSTF Defense in Depth (DID)/ Important to Safety (ITS) SSCs in Chapter 3 (Section 3.3.3.3.2 and Table 3.3-22) of the DSA (WSRC-SA-2002-00007, Rev. 16). WSRC-SA-2002-00007 Rev. 16, Section 3.3.3.3. 2 states that DID/ITS hazard controls are not required for inactive CSTF locations unless otherwise identified in Table 3.3-22. Table 3.3-22 does not identify any DID/ITS SSCs applicable to Tank 16 or this PA. The grout formulation is not identified as a CSTF Defense in Depth (DID)/ Important to Safety (ITS) SSCs. Therefore, the PA does not permanently eliminate a DID/ITS or degrade its safety function as explicitly described in the SB.
USQ-HTF-2015-00706 Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4 Page 5 of 7 Does the Proposed Activity involve a:
- a. Change to the facility as described in the Safety Basis? No
- b. Change to the procedures as described in the Safety Basis? No
- c. Test or experiment not described in the Safety Basis? No Justification:
- a. The Proposed Activity (PA) is the use-as-is disposition of the Supplier Deviation Disposition Request (SDDR) number 13307. The Safety Basis (SB) does not credit the grout formulation. The Safety Basis describes the grout formula; however, the PA does not conflict with these elements.
- 1) Per S-CHA-F-00010 (U-DCF-H-00279, Revision 0) (Waste Tank Grouting Consolidated Hazard Analysis
[CHA]), Section 2.3.1 Facility Configuration -
Typical grout is composed of Type I/II Portland cement, quartz sand, granite aggregate, water, fly ash, slag cement, and additives to enhance processing and flowability. To facilitate placement from the tank top, closure grout is flowable, pumpable, and self-leveling with cohesive properties to minimize segregation.
This PA aligns with the CHA description as the grout used is not outside of the typical component boundaries described therein. Bleed specification is not (nor should be) an integral component of the CHA. This PA does not conflict with the CHA description.
- 2) DSA Sections 2.5.3 (Waste Removal), 2.5.7 (Waste Tank/Equipment Grouting), and 3.4.1.5.2 (Facility Configurations and Design Inputs) describes the grout to be used for Tank Closures as reducing, flowable, pumpable, self-leveling, and designed to not heat the waste to boiling.
The PA aligns with these descriptions as the grout used continues to be reducing, flowable, pumpable, self-leveling, and designed to not heat waste to boiling. The identified, essential characteristics in the DSA will not be impacted by the PA.
The PA aligns with the facility as described in Documented Safety Analysis (DSA) (WSRC-SA-2002-00007, revision 16 and pending revision 17).
USQ-HTF-2015-00706 Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4 Page 6 of 7
- b. DSA Section 16.3.4 (Waste Tank and Ancillary Equipment Closure) states that the use of reducing grout is the most preferred environmental alternative and the least hazardous for closure of the waste tanks and associated equipment.
In addition, the PA ensures continued compliance with Configuration Management Program (DSA Section 5.5.4.2.8) as it (a.) ensures that changes to the technical baseline are properly developed, assessed, approved, issued, & implemented and (b.) complies with the facilities system for recording, controlling, and indicating the status of technical baseline documentation on a current basis.
Because the PA is in alignment with the facilitys approved, SB related procedures and governing processes/programs, no changes to procedures as described in the SB will result from this PA.
Therefore, the PA does not change procedures as described or implied in the SB.
- c. The PA does not change the facility nor does it require operating the facility in modes or conditions not previously analyzed in the DSA. The PA is not, and does not support, a test or experiment not described in the SB. The PA does not require equipment or SSCs to be operated in modes beyond which they were designed or previously evaluated in the Safety Basis. The PA is not a test or experiment that is not described in the Safety Basis.

- 1. Is this a new facility, new process, process change, or physical modification to an existing facility that could potentially introduce new hazards or increase the consequence or frequency of a current hazard, thereby impacting safety basis controls?
Justification:
The PA is not a new facility, new process, process change, or physical modification. The Proposed Activity (PA) is the use-as-is disposition of the Supplier Deviation Disposition Request (SDDR) number 13307. The PA is within the scope evaluated by S-CHA-F-00010, Revision 2 Waste Tank Grouting Consolidated Hazard Analysis. This PA does not impact or invalidate any conclusions of this CHA. The PA does not add new hazards or increase the frequency of a current hazard.
- 2. Is this a new facility, new process, process change, or physical modification to an existing facility that could potentially introduce new hazards, increase the consequences or frequency of a current hazard, or result in impacting the controls, associated with a current hazard that may cause a worker fatality or serious injury, CW or FW Radiation exposure > 5 rem, CW or FW Toxic Material Exposure > PAC-2, loss of equipment or facility > $2,000,000, or loss of production > 6 months?
Justification:
The PA is not a new facility, new process, process change, or physical modification. The Proposed Activity (PA) is the use-as-is disposition of the Supplier Deviation Disposition Request (SDDR) number 13307. The PA does not impact the consequences or frequency of a current hazard or control. The PAs unmitigated event consequences will not result in a worker fatality or serious injury, CW or FW Radiation Exposure > 5 rem, CW or FW Toxic Material Exposure > PAC-2, loss of equipment (>$2,000K),
facilities (>$2,000K), or production (> 6 months). The interim and final configuration will be managed through implementation of the requirements of the Manual 1Y and 2S. Therefore, the DHA process is not required.

Proposed Activity
Description:
The Proposed Activity (PA) is the use-as-is disposition of Supplier Deviation Disposition Request (SDDR) Number 13307 - Deviation from Specification C-SPP-F-00055, Revision 4.
Deviation
Description:
The Specification C-SPP-F-00055, Revision 4, Furnishing and Delivery of Tank Closure Grout, Section 3.2.1.2 Tank Closure Grout Mix, Item A.6 states the following: The trial batching shall demonstrate the ability to meet the maximum bleed of 0.0 after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Contrary to this requirement, several batches of grout used in filling Tank 16 were identified having bleed test results greater than the required 0.0%. The maximum value was 8.9%. Bleeding is one form of segregation, where water comes out to the surface of the concrete, being lowest specific gravity among all the ingredients of concrete. The disposition of the SDDR Number 13307 is a one-time use-as-is deviation from the specification requirement. Justification for deviation: The batches which exceeded the zero bleed requirements met all other performance requirements in the specification. In addition, the deviation does not invalidate the requirements of SRR-CWDA-2010-00128, Revision 1, Performance Assessment for the H-Area Tank Farm at the Savannah River Site.
With concurrence from C&WDA, Question 3 of the FTF/HTF UWMQ Applicability Determination - Is the PA a change to the waste tank stabilization fill grout formulation? was answered "No" because the PA does not compromise the assumptions or inputs of the Performance Assessment.
