SECTION XI RULES FOR INSERVICE INSPECTION OF NUCLEAR POWER PLANT COMPONENTS
Provides rules for the examination, inservice testing and inspection, and repair and replacement of components and systems in light water-cooled nuclear power plants. Application of Section XI begins when the requirements of the “construction code” (e.g., Section III) have been satisfied.
Section XI constitutes requirements to maintain the nuclear power plant while in operation and to return the plant to service, following plant outages, and repair or replacement activities. These rules require a mandatory program of scheduled examinations, testing, and inspections to evidence adequate safety. The method of nondestructive examination to be used and flaw size characterization are also contained within this Section.

REFERENCED ASME STANDARDS
Quality Assurance Requirements for Nuclear Facilities Applications (QA).
Qualifications for Authorized Inspection.
Standard for Level 1 / Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications.
Quality Assurance Requirements for Nuclear Facility Applications (QA).
Provides requirements and guidelines for the establishment and execution of quality assurance programs during siting, design, construction, operation, and decommissioning of nuclear facilities. This Standard reflects industry experience and current understanding of the quality assurance requirements necessary to achieve safe, reliable, and efficient utilization of nuclear energy and management and processing of radioactive materials.
NQA-1 focuses on the achievement of results and emphasizes the role of the individual and line management in the achievement of quality. It fosters the application of these requirements in a manner consistent with the relative importance of the item or activity.
Universal Engineering Services has more than a decades experience in the pressure vessel design for clients in UAE, Oman, Qatar, Kuwait, Bahrain, Saudi Arabia, and many more countries all over the world. UES work to many ASME standards to design and validate pressure vessels, boiler, fittings and piping systems. We are also experts in Stress analysis of piping, structural design, ASME Joint review, Design of Storage tanks, code calculations, FEA/FEM, and spotless service on design management.
