(Main)Nuclear energy - Determination of Gd2O3 content in gadolinium fuel blends and gadolinium fuel pellets by atomic emission spectrometry using an inductively coupled plasma source (ICP-AES) (ISO 16796:2022)
Nuclear energy - Determination of Gd2O3 content in gadolinium fuel blends and gadolinium fuel pellets by atomic emission spectrometry using an inductively coupled plasma source (ICP-AES) (ISO 16796:2022)
This document is applicable to the determination of gadolinium as Gd2O3 in powder blends and sintered
pellets of Gd2O3 + UO2 and ((U, Gd) O2) from mass fraction 10 g/kg to 100 g/kg (i.e. 1 % to 10 %), using
a suitable ICP-AES instrument.
This methodology is capable of demonstrating compliance with agreed upon fuel specifications and
associated data quality objectives provided the user has performed qualification measurements
under their established measurement control program to demonstrate that measurement uncertainty
requirements will be met with the desired level of confidence at the specification

Jedrska energija - Ugotavljanje vsebnosti Gd2O3 v mešanicah in peletih za gorivo iz gadolinija z atomsko emisijsko spektrometrijo z uporabo vira induktivno sklopljene plazme (ICP-AES) (ISO 16796:2022)
Ta dokument se uporablja za ugotavljanje gadolinija kot Gd2O3 v mešanicah prahu in sintranih peletih Gd2O3 + UO2 in ((U, Gd) O2) z masnim deležem od 10 g/kg do 100 g/kg (tj. od 1 % do 10 %) z atomsko emisijsko spektrometrijo z uporabo vira induktivno sklopljene plazme.
S to metodologijo je mogoče dokazati skladnost z dogovorjenimi specifikacijami goriv in povezanimi cilji kakovosti podatkov, pod pogojem, da je uporabnik izvedel kvalifikacijske meritve v okviru svojega vzpostavljenega programa za nadzor meritev, da dokaže, da bodo zahteve glede merilne negotovosti izpolnjene z želeno stopnjo zaupanja pri specifikaciji.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

ISO 16796 was prepared by Technical Committee ISO/TC 85, Nuclear energy, nuclear technologies, and
radiological protection, Subcommittee SC 5, Nuclear installations, processes and technologies.
This second edition cancels and replaces the first edition (ISO 16796:2004), which has been technically
revised.
