Low-level uranium and plutonium in synthetic nitrate solution
NUSIMEP-8 is an interlaboratory comparison open to all laboratories.
Participating laboratories in NUSIMEP-8 received one test sample of synthetic nitrate solution with undisclosed isotope amount ratio values n(234U)/n(238U), n(235U)/n(238U) and n(236U)/n(238U) and n(238Pu)/n(239Pu), n(240Pu)/n(239Pu), n(241Pu)/n(239Pu), n(242Pu)/n(239Pu).
Full confidentiality is guaranteed with respect to the link between measurement results and the participants’ identity.
The participation fee was €600 which includes sample dispatch.
Due to the nature of this comparison only a limited number of samples were available. Samples had been allocated to participants in order of registration until the stock of NUSIMEP 8 samples was exhausted. The coordination of NUSIMEP-8 had to be aligned time-wise with REIMEP-17, which was organised in parallel.
Registration for this inter-laboratory comparison was via the following link: https://web.jrc.ec.europa.eu/ilcRegistrationWeb/registration/registration.do?selComparison=860
The NUSIMEP-8 samples were shipped from the Institute for Transuranium Elements (EC-JRC-Karlsruhe) to the participants.
The measurement results had to be reported via the IRMM's online reporting tool at the latest on 1st of June 2013.
The NUSIMEP-8 reference values were sent to the participants on 1st of July 2013.
The participant results were evaluated against the reference values by means of z-scores and zeta-scores in compliance with ISO 13528:2005.
The NUSIMEP-8 report is available for download from the IRMM web-site.
In addition each participant received an individual certificate with the reported results, the NUSIMEP-8 reference values and the respective evaluation scores.
