Content:
review under this section, in conjunction with review under SRP Sections 11.3 and 11.5, verifies that the design of the turbine gland sealing system includes acceptable means to control the release of radioactive materials in gaseous effluents. Regulatory Guide 1.26 provides guidance regarding quality standards for the system. Meeting this criterion provides a level of assurance that the turbine gland sealing system is designed with proper controls over normal releases of radioactive effluents to the environment.29 (b) General Design Criterion 64 requires that means be provided for monitoring the reactor containment atmosphere, spaces containing components for recirculation of loss-of- coolant accident fluids, effluent discharge paths, and the plant environs for radioactivity DRAFT Rev. 3 - April 1996 10.4.3-4 that may be released from normal operations, including anticipated operational occurrences, and from postulated accidents. This GDC is applicable here because review under this SRP section, in conjunction with review under SRP Sections 11.3 and 11.5, verifies that the design provides for monitoring of releases of steam and noncondensables from the turbine gland seal system. Meeting this requirement provides a level of assurance that normal releases of effluents containing radioactive materials will be controlled to within acceptable limits.30 III. REVIEW PROCEDURES The ETSBSPLB reviewer selects and emphasizes material from this SRP section, as may be appropriate for a particular case. 1. ETSBSPLB reviews the equipment quality group classification to meet the guidelines of Regulatory Guide 1.26 (Ref. 2) . Exceptions are transmitted to MEBEMEB , which has 31 32 primary responsibility under SRP Section 3.2.2. 2. ETSBSPLB 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 provisions in accordance with SRP
