se construction permit SERs were dated before July 1, 1974 unless the licensee made a commitment in the construction permit record to use the 1974 standard, or unless the operating license application indicates the 1974 standard is to be used in which case, Category I will be the applicable criteria to be used. Category I is for plants whose construction permit SERs were dated after July 1, 1974. Subsection VI lists the documents which provide both acceptance criteria and evaluation guidance used in the review. The most important of these documents is IEEE Std 323 (augmented by Regulatory Guide 1.89), 'General Guide for Qualifying Class I Electric Equipment for Nuclear Power Generating Stations." This document, although specifically written for Class I electric equipment, contains a clear presentation of the principles and criteria that are generic to the environmental qualification process itself; therefore, IEEE Std 323 is considered applicable to the environmental qualification of other types of equipment. This document contains detailed criteria applicable to whatever method of qualification is used, i.e., type testing, analyses, operating experience, on-going qualification, or combined qualification. NUREG-0588 (endorsed by the Commission Memorandum and Order CLI-80-21 dated May 23, 1980), "Interim Staff Position on Electrical Equipment," discusses the staff position and acceptance criteria on the environmental qualification of electrical equip- ment. These criteria are general in nature and could also be applied to the) mechanical equipment. The environmental design and qualification of equipment is acceptable when it is ascertained that the criteria of NUREG-0588 have been met. IEEE Std 334, "Guide for Type Tests of Continuous-Duty Class I Motors Installed Inside the Containment of Nuclear Power Generating Stations" (augmented by Regulatory Guide 1.40); IEEE Std 382, nGuide for Type Test of Class I Electric Valve Operators for Nuclear Power Generating
