lh"-IC-SD-UM-.SEMP-O03 REV. 0

Prepare a trade 8tud.y t o e'4aluate leakage detection, monitoring, and imitigation technologies to support retrieval of the waste fr~cirl the single-shell tanks.

Operational Leak.-Detection and Minimization

Prepare a trade study t o determine the appropriate operational responses to tank leakage during retrieval activities. Base the study on the leak requirements in the Functions and Requirements document (Cruse, 1995) for Single Shell Tank retrieval.

Project Development Specification (PDS)

The ISSTRS project will prepare a PDS which is a lower-level specification based on the Project functions and requirements analysis (in the TRS) and traceable to the program-level requirements in the DRD. Provided as basis to perform design. The PDS will be formatted per Mil-Std-490 (EP 1.2).

Project Design Concept(PDC)

The ISSTRS project will prepare a PDC which i s a project level BSD formatted per WHC-EP-0586.

Technical Performance Measurement (TPM)

The ISSTRS project will prepare two TPMs, one to determine the actual retrieval rate(s) of the retrieval system and one to determine the degree o f tank clean-out achievable with the retrieval system.

Hazardous Material Inventory (HMI)

The project will prepare a project specific HMI.

System Integration Plan (SIP)

The project will prepare a SIP that includes a project schedule and project cost estimate.

2.2 TWRS SEMP Exceptions

The following are deletions or revisions to the direction contained in the TWRS SEMP that will be followed. by the ISSfRS project.

Design Requirements Document (DRD)

The DRD is not yet available to update so ISSTRS will prepare a Project Mission Analysis Report (Hertzel 1996a) and an "equivalent" or project DRD (Hertzel 1996b) along with an up front determination of the program risks assumed by this process (Peck 1996).

Flow Sheets

The TRBL flow sheets are not expected to be completed by the time they are needed by the ISSTRS project. Therefore,

4


project specific flow sheets will be developed for ISSTRS. These will be patterned after the W320 flow sheets.

Interface Control Document (ICD)

The pre-concept and concept phase draft ICDs will be combined into draft ISSTRS project ICDs. These documents will be prepared in accordance with the guidelines in the TWRS System Engineering Manual (WHC 1995b).

System Effectiveness Analysis

A single, combined System Effectiveness Analysis will be prepared for the system definition phase of the ISSTRS project.

Requirements Traceability

The requirements traceability and system assessment will be combined into a single Requirements Traceability supporting document describing how each requirement/constraint is met by the conceptual design. This is to address each item in the Function and Requirements Document (FRD), the (equivalent) DRD, and the TRS.

Project Configuration Management Plan

The ISSTRS project will use the existing TWRS configuration management policies as delineated in the TWRS Systems Engineering manual (WHC 1996b), Section 5. Therefore, a project configuration management plan is not required.

Life Cycle Cost Analysis (LCCA)

The LCCA is a tool to assist in the evaluation of alternatives. WHC has been directed by DOE RL (Erickson 1995) to use past practice sluicing as the waste retrieval method for ISSTRS. Since other waste retrieval alternatives have been eliminated, a LCCA is not required for the ISSTRS project and will not be produced. However, this item i s one of the critical ISSTRS decisions that require validation by the decision board or decision officer. Accepting this direction without validation and going forward with the ISSTRS project will be carried as a "risk".

Test and Evaluation Plan (TEP)

ISSTRS is a demonstration project that uses the designs and systems from project W320 therefore confirmation testing is not required and a TEP will not be prepared for ISSTRS. of the overall ISSTRS goals are to determine 1) the actual waste retrieval rate, and 2) to determine the degree of cleanout achievable with the retrieval system. These goals cannot be determined until the operational phase of the task and are not part of the ISSTRS project.

Two

System Design Description (SDD)

5


The SDD is one of the primar,y technical documents produced in the "System Definition Phase" of the project. The SDD may contain the items listed above as "chapters" or the items may be produced as stand-alone documents (if determined to be more feasible and cost effective by the project). If they are included as SDD chapters, the chapter titles will be the same as in this SEMP so there is a one- to-one correlation. Drawings and analysis produced during the system definition phase will be included in the SDD.

Reviews

The Design Requirements Review (DRR) and the System Requirements Review (SRR) will be combined into a single review that will be conducted at the end of the System Definition Phase of the project. This review will complete the Design Configuration Baseline (DCBL) portion of the ISSTRS project.
