Analytical Chemistry Laboratory Measurement Control Committee
Share |

The N15/INMM 5.1 Analytical Chemistry Laboratory Measurement Control Committee, a subcommittee of the ASC N15 Methods of Nuclear Material Control, develops and reviews principal elements of a comprehensive measurement control program for analytical chemistry laboratories supporting the management of nuclear materials. 

In 2017, ANSI approved and published ANSI N15.51-2017, a revision and update to ANSI N15.51-2007 Methods of Nuclear Material Control -- Measurement Control Program -- Nuclear Materials Analytical Chemistry Laboratory. It is available for purchase on ANSI Webstore.

From its inception in 1986, INMM 5.1 has been involved in the contributions to and the review of a series of documents describing the International Target Values (ITVs) for measurement uncertainties in safeguarding nuclear materials prepared under the cognizance of the International Atomic Energy Agency.

(The ITVs are the uncertainties to be considered in judging the reliability of analytical techniques applied to industrial nuclear and fissile material, which are subject to safeguards verification. The tabulated values represent estimates of the state of the practice, which ought to be achievable under routine measurement conditions. The latest ITV document was published in November 2010.)

Other INMM 5.1 efforts have been directed toward application and implementation of measurement control techniques in nuclear analytical chemistry laboratories.  The ASC N15 / INMM 5.1 Subcommittee routinely holds an annual meeting  in conjunction with the INMM Annual Meeting held in July of each year.  Contact the N5.1 Subcommittee Chair for additional information.
