ANS publishes revised standard on PWR reload startup physics tests
February 25, 2020, 2:43PMANS News
The ANS Standards Committee has just published ANSI/ANS-19.6.1-2019, “Reload Startup Physics Tests for Pressurized Water Reactors” (revision of ANS-19.6.1-2011). The standard, approved December 19, 2019, provides guidance for verifying the nuclear characteristics of a commercial pressurized water reactor core following a refueling or other alteration of the reactor core for which nuclear design calculations are required. The standard provides the minimum acceptable startup physics test program, while recognizing that additional tests may be required by special design features of a particular core.
