<p>1966: Nuclear criticality safety code
</p><p>The KENO Monte Carlo code built a foundation for future nuclear computing codes that are now producing invaluable modeling of today’s nuclear reactor fleet—including a simulation of the pin powers of the AP1000 nuclear reactor.

ORNL develops the KENO Monte Carlo code for use in nuclear criticality safety assessments and provides benchmark data against which the computer code calculations can be checked. This technology leads to future significant code enhancements and additional validation.
