ctive materials, but are not part of the reactor coolant pressure boundary and are not important to safety. 2. Regulatory Guides 1.33 and 1.123 as they relate to the quality assurance programs for the turbine gland sealing system components that may contain radioactive materials. Specific criteria necessary to meet the relevant requirements of 10 CFR Part 50, Appendix A, General Design Criteria 60 and 64 are as follows: The turbine gland sealing system should be designed to provide for the collection and condensation of sealing steam and the venting and treatment (as required in Ref. 1) of noncondensables. Quality Group D as defined in Regulatory Guide 1.26 (Ref. 2) and a nonseismic design classification are acceptable design criteria for this system. III. REVIEW PROCEDURES The ETSB reviewer selects and emphasizes material from this SRP section, as may be appropriate for a particular case. 1. ETSB reviews the equipment quality group classification to meet the guide- lines of Regulatory Guide 1.26 (Ref. 2). Exceptions are transmitted to MEB, which has primary responsibility under SRP Section 3.2.2. 2. ETSB reviews the system P&IDs to determine the source of sealing steam and the disposition of steam and noncondensables vented from the gland seal. The review includes the radiological processing and monitoring provi- sions in accordance with SRP Sections 11.3 and 11.5. 3. ETSB reviews the quality assurance for the design, construction, and operational phases for the turbine gland sealing system according to the guidelines of Regulatory Guides 1.33 and 1.123 (Refs. 3 and 4). Exceptions are trans- mitted to QAB which has primary responsibility under SRP Sections 17.1 and 17.2. 10.4.3-2 Rev. 2 - July 1981 IV. EVALUATION FINDINGS ETSB verifies that sufficient information has been provided and that the review is adequate to support conclusions of the following type. to be included in the staff's safety evaluation report: The turbine gland sealing system includes the
