Cohen and Associates.; Battelle Memorial Institute. Columbus Laboratories.;]. The Option B requirements and NEI guidance are based on NUREG, “Performance Based Containment Leak-Test Program.” Based on the information provided by the operating data and their risk significance, the study calculated the change in risk (in person-rem) to public for the 15 alternatives considered in the : Hans Ashar, Eugene Imbro, David Terao. The reactor containment leakage test program includes the performance of integrated leak rate testing (ILRT), also known as Type A test, containment penetration leak rate testing — Type B tests, and containment isolation valve leak rate testing — Type C test. The Type B and Type C tests are also referred to as local leak rate tests (LLRTs).

The feasibility study of reducing the frequency of ILRT from 1 every 5 years to 1 every 10 years was performed with the method of performance-based containment leak-test program (NUREG). To verify the justification of relaxation of test frequency, two activities were : Hae-Cheol Oh, Mi-Ro Seo, Myung-Ki Kim, Bag-Soon Chung, Sung-Yull Hong. Revision 3-A of NEI allows, based on previous valve leak test performance, an extension of Type C containment isolation valve leak test intervals. Since the change involves only performance-based Type C testing, the proposed amendment does not involve either a physical change to the plant or a change in the manner in which the plant is.

  This O-ring is specific to the functional element of mechanical line leak detectors and is, therefore, only present on certain types of ALLDs. In addition, all functional elements will be tested as part of the simulated leak test conducted at 3 . The NRC disagrees with the comment, in part, given that for the vast majority of licensees implementing Option B of 10 CFR p Appendix J, the argument could be made that containment modifications are implemented under the Inservice Inspection Program in accordance with ASME Section XI, Subsection IWE (for Class MC containments) pursuant. Abstract. This study was composed of three parts: a post cure study to optimize final properties of an ethylene-propylene-diene (EPDM) formulation, an accelerated aging study to compare the stress relaxation behavior of a butyl and an EPDM elastomer under compression, and a cursory evaluation of a new 70 Shore A EPDM. The data will support the technical basis to extend the annual maintenance of the EPDM O-rings in the H shipping package and to predict the life of the seals at bounding service conditions. Current expectations are that the O-rings will maintain a seal at bounding normal temperatures in service ( F) for at least more» 12 months.
