1.0 PURPOSE

The purpose of this report is to document the evaluation of the ability of the modifications to the241-AW Clean-Out Boxes (COB) AW-3, AW-5, and AW-7 to perform their safety function(s)under those conditions and events for which the safety functions are required.

Compliance with the critical characteristics and controls identified in this Functions andRequirements Evaluation Document (FRED) shall be verified and documented. Acceptablemeans of verification can be accomplished by one or more of the following means:

*Testing,*Evaluation,*Inspection,*Code compliance,*Procurement from a qualified supplier,*Certificate of Compliance or material certification,*Commercial Grade Itemn (CGI) Dedication,

* Independent Qualified Registered Professional Engineer review and approval, or" Nonconformance Report Disposition.

Documented evidence of compliance shall be identified in the Safety Equipment List.

2.0 APPROACH

Normal, accident, and off-normal operating conditions, environmental/climatic events, andpotential failures were considered for the 241-AW COBs AW-3, AW-5, and AW-7 modificationevaluation following U.S. Department of Energy (DOE) safety orders and guidance. Theexisting tank farm Safety Basis, combined with directly relevant and applicable waste transferline experience within tank farms operating history, were considered and utilized to their fullvalue and extent to support completion of the 241 -AW COB modifications FRED. The system,structures, and components (SSC) safety function (i.e., prevent or mitigate accidents) isdeveloped through the iterative hazard/accident analysis and safety controlsdevelopment/evaluation processes conducted at specified stages of, and in parallel with, thedesign process.

Safety functional requirements are developed by identifying SSC performance requirementsnecessary to accomplish the safety function. Some of these requirements may be developedduring hazard and accident analysis, while others may be developed through engineeringevaluation. Still others may be developed through a Process Hazard Analysis and evaluation ofconditions (modes) that could cause SSC failure.

The following sections of this report document the results of the processes and activitiesdescribed above which led to the definition of the 241-AW COB modifications' safety functionalrequirements, safety performance criteria, and key design aspects and critical characteristicsnecessary for the waste transfer pipes the COBs are associated with to perform their safety

5


function. This report also includes summaries of information discussed relative to the wastetransfer piping operability in normal and off-normnal operating conditions, and during applicableenvironmental and climatic events.

3.0 SCOPE

The scope of this report includes the following information with respect to the 241 -AW COBsAW-3, AW-5, and AW-7 modifications.

1. Documentation of safety SSC functional and performance requirements necessary forsafety SSCs to perform their intended safety functions. The safety SSC functionaland performance requirements were identified from design requirements, engineeringevaluation and calculations, the iterative hazard/accident analysis safety controlsdevelopment/evaluation process, and Process Hazard Analysis.

2. Documentation of key design aspects and safety SSC critical characteristics necessaryfor safety SSCs to perform their intended safety functions and identification of howthe key design aspects and safety SSC critical characteristics can be verified to bemet. Critical characteristics documented in this report's appendices are used in theCGI dedication process to establish a subset of component-specific criticalcharacteristics for use in CGI dedication to provide reasonable assurance the safetySSC is acceptable and will perform its safety-related function.

3. Documentation of additional safety SSC design and operability requirements, notdirectly associated with the credited safety SSC safety function; and discussion as tohow these additional requirements are met. These requirements fall into two generalcategories and can be defined generically as follows:

a. Design - Safety SSCs must be designed to reliably perform their safety functionunder those conditions and events for which their safety function is intended.

b. Environmental - Environmental conditions (e.g., natural phenomena, flooding,etc.) must be considered to ensure that safety SSCs can perform their safetyfunctions, as determined by the safety analysis, under postulated serviceconditions.

4. A summary of waste transfer line control development/evaluation discussions whichprovide background for the basis for selected safety SSCs.

In addition to the process approach described in Section 2.0 (DOE safety orders and guidance),the development/evaluation process used to derive the key design aspects and safety-SSC criticalcharacteristics documented in this report followed an approach similar to Electric PowerResearch Institute (EPRI) NP-5652, Guideline for the Utilization of Commercial Grade Items inNuclear Safety Related Applications , and EPRI TR-102260, Supplemental Guidance for theApplication of EPRI Report NP-5652 on the Utilization of Commercial Grade Items, forperforming and documenting technical evaluations. This approach helps ensure CGIs willperform their required safety functions. Subsequent CGI dedication training and mentoring

6


provided by the Sequoia Consulting Group has been used as a method to validate engineeringjudgment used in selecting acceptable safety-SSC critical characteristics documented in thisreport and the corresponding CGI documentation.

This report documents the evaluation of the 241-AW COBs AW-3, AW-5, and AW-7modifications' safety functions.

4.0 SAFETY FUNCTION

Primary waste transfer piping systems are identified as safety-significant SSCs per the pendingamendment 45 in Engineering Change Notice (ECN)-725337-RO, Safety -Signi~ficant Designationof Tank Farm Waste Transfer Primary Piping Systems. Secondary encasements are referencedin ECN-725337-RO as underground piping equipment for pip-in-pipe designs. The safetyfunction of the waste transfer lines is defined as listed below.

1 . The identified safety function of the waste transfer primary piping system is toprovide confinement of waste; thus, decreasing the frequency of a waste transfer leakaccident.

2. The secondary encasement piping is to provide encasement to the primary pipingsystem in the case of a failed pipe to collect leaks and deliver them to a detectionpoint. The secondary encasement provides better leak confinement than otherconfigurations as it can be leak tested for integrity.

5.0 SYSTEM DESCRIPTION

Certain waste transfer lines installed between the 242-A Evaporator and 241 -AW Tank Farmwere equipped with COBs. COBs provided access to the slurry and supemate lines to facilitateclearing piping plugs encountered during normal operating conditions. The COBs are notcompliant with the Resource Conservation and Recovery Act of 1976 (RCRA). To use the wastetransfer lines equipped with COBs, the COBs must be removed in such a way as to leave thewaste transfer piping compliant with RCRA.

Figure 5-1 shows the typical COB configuration on the waste transfer lines between the 242-AEvaporator and 241 -AW Tank Farm.

The modifications to the COBs necessary to make the associated waste transfer lines RCRA-compliant involve disconnecting the two waste transfer lines and removing the surface portionsof the COBs. The planned modifications are shown in Figure 5-2.

Once the COB modifications are complete, the following components will serve the safetyfunctions identified in Section 4.0:

* 1 -inch socket weld caps,

* 2-inch pipe cap with pipe spool, and

* 12-inch pipe cap with pipe spool.

The 1 -inch pipe caps complete the primary pipe confinement/pressure boundary. The wastetransfer lines installed between 242-A and 241-AW were designed to accommodate a wastepressure of 400 psig. The 1 -inch pipe caps must be capable of meeting or exceeding the originaldesign pressure of 400 psig.

The 2-inch pipe cap with pipe spool and 12-inch pipe cap with pipe spool complete thesecondary or encasement pipe confinement/pressure boundary. The waste transfer lineencasements installed between 242-A and 241 -AW were designed to accommodate a leakedwaste pressure of 60 psig. The pipe cap and spool assemblies must be capable of meeting orexceeding the original design pressure of 60 psig.

The modifications to the COBs and waste transfer lines and the associated required tests arecompliant with ASME B31.3.

5.1 BOUNDARIES

Per ECN-725337-RO, the boundaries of the waste transfer piping system encompass all pipingand piping connections and components to the waste tank riser. Based on this boundarydetermination, the following components will serve the safety functions identified in Section 4.0once the modifications are complete:

* 1 -inch socket weld caps,

* 2-inch pipe cap with pipe spool, and

* 12-inch pipe cap with pipe spool.

The 1 -inch pipe caps complete the primary pipe confinement/pressure boundary. The 2-inchpipe cap with pipe spool and 12-inch pipe cap with pipe spool complete the secondary or

* encasement pipe confinement/pressure boundary. The modifications to the COBs and wastetransfer lines and the associated required tests are compliant with ASME B3 1.3.

5.2 INTERFACES

There are no interfaces between the COB modification components and other safety designatedSSCs other than the interface with the components being modified. The COB modificationinterfaces include SN-219 and SL- 168, the heat trace system, and the leak detection system. The

9


leak detection modification removes the existing COB AW-3 leak detector and does not involvethe installation of new leak detection equipment. The operability of the leak detection systemwill be verified by completion of functional tests of the remaining leak detection devices. Theleak detection system will not be further discussed in this FRED.

6.0 SYSTEM EVALUATION

This evaluation focuses only on the 1 -inch socket weld caps, 2-inch pipe cap assemblies, and the12-inch pipe cap assemblies. Associated equipment required to complete the waste transferpiping system, e.g., welding rod, heat trace, and insulation, are not discussed.

6.2 FAILURE MODE EVALUATIONS

The following failure mechanisms have been identified for the waste transfer piping.

1. Chemical incompatibility with the waste stream such that the piping is eitherdamaged or corroded;

2. Piping components are not as represented (e.g., not per ASTM standards) such thatthe strength of the material is not appropriate; and

7.0 CONTROLS

7.1 PERFORMANCE CRITERIA

The performance criterion for the waste transfer piping is the same as the functional requirementof the piping: maintain structural integrity. The safety function of the waste transfer pipingsystem is ensured by designing, fabricating, testing, and inspecting the piping to ASME B3 1.3.

7.2 FUNCTIONAL TESTS

Operability of the waste transfer piping system is ensured though the implementation of ASMEB31.3. Testing is performed to verify the welds associated with the modifications are intact andhave sufficient structural strength to maintain structural integrity. Testing is also performed onthe components to ensure that they are consistent dimensionally and chemically with the ASTMstandards required by ASME B3 1.3

8.0 CRITICAL CHARACTERISTICS

This document addresses only critical characteristics directly traceable to component safetyfunctions. The following sections identify preferred method(s) of verifying criticalcharacteristics of safety SSCs for use in the CGI process. However, at the time of verification,alternate but equivalent methods best suited to the situation may be identified, used, anddocumented. In addition, critical characteristics not directly related to the component's safetyfunction may be specified on the CGI dedication form in order to support reasonable assurancethat the CGI received matches the item specified. These additional specifications may include,but are not limited to, documentation and additional physical characteristics of the components(i.e., markings, dimensional checks, etc.). CGI dedication is not required for safety SSCsprocured from an evaluated supplier.
