A. INTRODUCTION
General Design Criterion 50, "Containment DesignBasis," of Appendix A, "General Design Criteria forNuclear Power Plants,"
to IOCFR Part 50, "Licensing of Production and Utilization Facilities"
requires, inpart, that the reactor containment structure, including penetrations, be designed so that the contain.ment structure can, without exceeding the designleakage rate, accommodate the calculated pressure, temperature, and other environmental conditions resulting from any loss-of-coolant accident.
Appendix Bto Part 50, "Quality Assurance Criteria for NuclearPower Plants and Fuel Reprocessing Plants,"
establishes quality assurance requirements for the design,construction, and operation of nuclear power plantstructures, systems, and components.
This guidedescribes an acceptable method of complying withAppendix B and Criterion
56 of Appendix A withrespect to the mechanical, electrical, and testrequirements for the design, construction, andinstallation of electric penetration assemblies incontainment structures for water-cooled nuclear powerplants. The Advisory Committee on Reactor Safeguards has been consulted concerning this guide and hasconcurred in the regulatory position.
