to the evaluation of vendor processes described in EPRI TR-106439. The guidance of BTP HICB-14 or the guidance of EPRI TR-106439 may be applied to the qualification of software tools, as discussed in Section 5.3.3 of IEEE Std 7-4.3.2. As discussed in the standard, the activities involved in tool qualification may be tailored based upon the potential safety impact the tool may have. Section 5.3.3 discusses a case in which the tool safety impact may be limited by verification and validation of tool outputs. NUREG/CR-6421, "A Proposed Acceptance Process for Commercial Off-the-Shelf (COTS) Software in Reactor Applications," describes criteria that may be used in tailoring the qualification process for software tools. 9. Section 5.4 — Equipment Qualification The applicant/licensee should confirm that the safety system equipment is designed to meet the functional performance requirements over the range of normal environmental conditions for the area in which it is located, as identified by Sections 4.7 and 4.8. Rev. 4 — June 1997 SRP 7.1-C-7 HICB reviews mild environment qualification and electromagnetic interference (EMI) qualification of safety system I&C equipment, and consults with other branches to confirm qualification for harsh environments and seismic loads. The review of harsh environment qualification is coordinated with the Electrical Engineering Branch (EELB). The review of seismic qualification is coordinated with the Mechanical Engineering Branch (EMEB). Mild environment qualification should conform with the guidance of ANSI/IEEE Std 323, "IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations." Additionally, the applicant/licensee should confirm that a single failure within the environmental control system, for any area in which safety system equipment is located, will not result in conditions which could result in damage to the safety system equipment, nor prevent the balance of the safety system not within the area from
