throughout the life of the component. Metallic and non-metallic materials used in the control rod drive mechanism and not included in Appendix I to Section III of the ASME B&PV Code are identified. 4. Cleaning and Cleanliness Control Proper care should be taken in handling the materials and parts of the control rod drive mechanism during fabrication, shipping, and onsite storage to assure that all cleaning solutions, processing compounds, degreasing agents, and other foreign materials are completely removed, and that all parts are dried and properly protected following any flushing treatment with water. In addition, MTEB will coordinate other branches' evaluations that interface with the overall review of tte system as follows: the Mechanical Engineer- ing Branch (MEB) reviews the mechanical aspects of the control rod system other than the reactivity control elements as part of its primary responsi- bility for SRP Section 3.9.4. The Core Performance Branch (CPB) reviews the mechanical design, thermal performance, and chemical compatibility of the reactivity control elements as part of its primary responsibility for SRP Section 4.2. For those areas of review identified above as being reviewed as part of the primary review responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. II. ACCEPTANCE CRITERIA MTEB acceptance criteria are based on meeting the relevant requirements of the following regulations: a. General Design Criterion 1 as it relates to structures, systems, and components important to safety being designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. 4.5.1-2 Rev 2 - July 1981 b. General Design Criterion 14 as it relates to the reactor coolant pressure boundary being designed, fabricated, erected, and tested so as to have an extremely low
