ion, and systems installation. In a sufficiently complex system, these procedures may contain some errors, and one of the things a reviewer should monitor is how these errors are identified, corrected and documented. These corrections should be subject to the same quality and configuration control as the rest of the system. B.3.1.6 Software Maintenance Plan (SMaintP) Clause 5.4.2.3, “Maintenance of Commercial Dedication,” of IEEE Std 7-4.3.2, “IEEE Standard Criteria for Digital Computers in Safety Systems on Nuclear Power Generating Stations,” which is endorsed by RG 1.152, “Criteria for Use of Computers in Safety Systems of Nuclear Power BTP 7.14-26 Draft Revision 6 - August 2015 Plants,” contains guidance on maintenance and configuration management for commercially dedicated items. NUREG/CR-6101, Section 3.1.9, “Software Maintenance Plan,” and Section 4.1.9, “Software Maintenance Plan,” contain guidance on SMaintPs. The SMaintP should exhibit the management, implementation and resource characteristics listed below. B.3.1.6.1 Management Characteristics of the SMaintP The management characteristics that the SMaintP should exhibit include purpose, organization, responsibilities, risks, and security. Purpose refers to a general description of the software maintenance process and the goals of that process. The SMaintP should list the general functions that the software maintenance organization will be expected to perform, and provide general information on obtaining field trouble reports. Maintenance should be limited to the process of modifying a software design output to repair nonconforming items or to implement pre-planned actions necessary to maintain performance. Modifications to improve performance or other attributes, or to adapt the design outputs to a modified environment should be considered design changes. Organization involves a description of the software maintenance organization. The SMaintP should describe the boundaries between the
