Software quality assurance documentation for the release of NUFT 2.0 for HP platforms

摘要

This document is the Individual Software Plan (ISP) for version 2.0 of the Non-isothermal Unsaturated-saturated Flow and Transport (NUFT.) analysis computer program. This document addresses the applicable requirements of LLNL YMP procedure 033-YMP-QP 3.2, Section 4.2.1.1. The purpose of this ISP is to plan and organize the activities required to certify the NUFT code for quality affecting work involving problems that include cross drift analysis of the Yucca Mountain Repository facility. NUFT is software for application to the solution of a class of coupled mass and heat transport problems in porous geologic media including Yucca Mountain Repository Cross Drift Problem (YMRCDP- also known as the Enhanced Characterization of the Repository Block (ECRB)). Solution of this class of problems requires a suite of multiphase, multi-component models for numerical solution of non- isothermal flow and transport in porous media with applications to subsurface contaminant transport problems. NUFT is a suite of multiphase, multi-component models for numerical solution of non- isothermal flow and transport in porous media, with application to subsurface contaminant transport problems, and in particular, to the hydrology in and about the Yucca Mountain Repository Site. NUFI? is acquired software, as defined by 033-YMP-QP 3.2, and a preliminary baseline of source code, electronic documentation, and paper documentation has been established as required by 033-YMP-QP 3.2, Section 4.1. NUFT runs on Sun Unix platforms, Solaris operating system version 5.5 and HP-UX with operating system version 10.20. The product to be qualified under this ISP is the version running on HP- UX. The HP version will be labeled Version 2.0h. The ?h? is included to distinguish the HP version from possible future versions qualified for Sun or other platforms. The scope of the plans and procedures outlined in this ISP is limited to the effort required to qualify NUFT for the class of problems identified in section 1.1 above, to meet the applicableiequirements of 033-YMP-QP 3.2, and to establish a Version 2.0 baseline for subsequent qualifications of NUFT for additional problems or for use on additional platforms. The detailed requirements applicable to the class of problems for which this release is applicable will be defined in the NUFT 2.0 Requirements Document. The scope of this ISP is limited to NUFT. Auxiliary software such as the post-processing tool XTOOL, YMESH, -and RADPRO, which are often used in conjunction with NUFT, will be addressed separately as needed. Version 2.0 is the first quality controlled release for the NUFT software. Additional releases are anticipated. NUFT Version 2.0 is ?acquired software,? as defined by 033- YMP-QP 3.2. Version 1 .O was released in February 1998, but that certification is being withdrawn based upon the quality assurance surveillance findings described in LLNL-98- D-065.
