oncrete Reactor Vessels and Containments.* 2. Changes in prestressing element materials or in anchorage items of previously accepted systems that may require repeating the system performance tests are identified in Subsections CB and CC, Article 2466 of the Code for Concrete Reactor Vessels and Containments. 3. Any new post-tensioned prestressing system should meet the requirements set forth in the Code for Concrete Reactor Vessels and Containments. 4. The use of any post-tensioned prestressing system should permit the application of an inservice inspection program that will verify the continued functional capa- bility of the structure. Implementation of this program should not degrade the quality and reliability of the post-tensioned prestressing system. Regulatory Guides 1.35, "Inservice Inspection of Ungrouted Tendons in Prestressed Concrete Containment Structures," and 1.90, "Inservice Inspection of Prestressed Concrete Containment Structures with Grouted Tendons," should be consulted for recommendations concerning the use of ungrouted and grouted concrete containments, re- spectively. *ASME Boiler and Pressure Vessel Code, Section III, Division 2 (the latest version, plus addenda, as endorsed by the Nuclear Regulatory Commission). This Code is currently under review for endorsement by the NRC staff.
