CAESAR II Nuclear
CAESAR II Nuclear is a unique solution that leverages the power and quality that CAESAR  II has built for nearly 30 years.  CAESAR II Nuclear complies with ASME NQA-1 2008/09 quality assurance (QA) standards required for nuclear facility design as endorsed by the Nuclear Regulatory Commission (NRC). This new software solution boasts additional features over CAESAR II allowing for direct adoption in nuclear sector for both new and existing facilities.

Global Adoption and Standardization

CAESAR II, with its 34+ piping global codes, is used by more OO’s and EPC’s in more than more than 80 countries. CAESAR II is known for its technical superiority, flexibility, ease of use, innovation and constant reliability. CAESAR II now complies with ASME NQA-1 2008/09 quality assurance (QA).

ASME Nuclear Quality and Assurance

To ensure the total quality and integrity of CAESAR II Nuclear, as required by the ASME NQA-1, Intergraph conducted hundreds of automated numerical, usability and workflow tests. During development all steps have test plans which incorporate multiple review levels to ensure a robust and high-quality industry solution.

Commercial Grade Dedication

The Commercial Grade Dedication (CGD) acceptance process as outlined in  ASME NQA-1-2012 Subpart 3.2-214, includes detailed verification of results using alternate calculation tools and verification tests such as the NRC benchmarks.
These results and comparisons are published in a CGD Guide to document the software’s accuracy. The CGD technical verification guide is available separately for CAESAR II Nuclear users.

Quality Assurance and Reporting

US customers of CAESAR II Nuclear will have access to QA reporting to keep them fully informed about issues and software changes to help them comply with U.S federal requirements 10 CFR Part 50 App. B. and 10 CFR Part 21.

Overall Quality Improvements
Following higher QA standards, improves the overall quality of all CAESAR II products, and provides users of both CAESAR II and CAESAR II Nuclear even higher than normal confidence in a tool that has delivered quality results for nearly 30 years.

Links to Design

CAESAR II solutions offer many time saving interfaces such as bi-directional links between plant design and engineering analysis. This link exists between Intergraph SmartPlant® 3D and Intergraph CADWorx® Plant Professional and allows the passing of design and analysis data between design and analysis without data loss.

Links to Third-Party Analysis Solutions
CAESAR II also connects to third-party analysis tools, which helps leverage specialized analysis results to and from CAESAR II. These links range from direct interface links to finite element and hydraulic analysis, to links to other systems through the CAESAR II published neutral file or Intergraph PCF file format.


Capabilities and Standards Overview


CAESAR II Nuclear addresses the needs of the nuclear industry by adhering to various required nuclear standards and procedures. This helps ensure that the programs delivers the required quality this challenging sector demands. These capabilities include:
  • Commercially dedicated using the new ASME NQA-1-2012 Subpart 3.2-214 Commercial Grade Dedication (CGD) acceptance process for software. This assures the product has passed critical acceptance tests, analyses and inspections, as well as performance requirements, characteristics, and vendor history.

  • Support included for U.S. NRC requirements, 10 CFR Part 50 App. B (Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants) and 10 CFR Part 21 (Reporting of Defects and Noncompliance). For U.S. customers, bundling of a Quality Assurance and Reporting notification service.

  • For additional design and input verification a text with piping input is available

  • Incorporation of verification software, CAESAR II QATest, for comparing benchmark output with the output generated for an installation.
  • For nuclear licensees of CAESAR II Nuclear, enhanced critical-level technical support is included.
