A reference worldwide model for antineutrinos from reactors
Purpose of this web page
This page provides update of data published

Marica Baldoncini, Ivan Callegari, Giovanni Fiorentini, Fabio

worldwide model for antineutrinos from reactors" Physical Review D 91,

The content of the web page is intended as additional material to the
publication: we directly address to the paper for the definition of
physical quantities, units of measurement and for literature
references. Signal prediction update concerns exclusively reactor
operational conditions, which are taken from the annual publication
“Operating Experience with Nuclear Power Stations in Member States” of
the Power
Reactor Information System (PRIS) of the International Atomic
Energy Agency (IAEA). This information is collected in a comprehensive
database, compiled starting from 2003 and updated every year.

The worldwide map of reactor antineutrinos signals
The worldwide map of reactor antineutrino signals

The 1° x 1° map provides the worldwide predicted reactor antineutrino signal in the low energy region expressed in Terrestrial Neutrino Units (TNU), obtained using 2013 reactor operational data. The signal evaluation is performed by modeling the 3 reactor antineutrino life stages: production, propagation and detection. For the calculation of the reactor signal starting from 2003 we keep fixed the following 5 ingredients, chosen according to updated estimates of 2013:
- the reactor antineutrino spectrum;
- the energy released per fission;
- the fission/power fractions;
- the neutrino oscillation parameters;
- the inverse beta decay cross section.
The database of the operating commercial reactors is compiled starting from 2003 on a yearly basis and updated every year according to the information published by the PRIS. The 19 database columns are structured as follows:
- core country acronym;
- core name;
- core location (latitude and longitude in decimal degrees);
- core type;
- use of Mixed OXide (MOX) fuel (1 for yes, 0 for no);
- thermal power Pth [MW];
- 12 columns listing the monthly load factors LF [%].
For
parameters definitions we refer to the PRIS.
The following links, grouped year by year, point to the reactor records
database in xls format, to a zip containing the signal numerical maps
in the Low Energy Region (LER) and in the Full Energy Region (FER) in
ASCII format and to a zip file containing the maps in png format of the
signal in the LER and in the FER The columns of the numerical map file
are respectively longitude and latitude (in decimal degrees) and the
reactor antineutrino signals in TNU.

Signal contribution of close by reactors
The location map, produced according to the 2013 reactor operational status, illustrates the percentage contributions to the signal given by the close-by reactors for the three long baseline experiments KamLAND, Borexino and SNO+ and for the proposed medium baseline experiments Juno and RENO-50.
Predicted reactor antineutrino signals
The
1° x 1° map shows the worldwide ratios between the expected
reactor signal in the low energy region and the geoneutrino signal [Huang
et al. 2013], produced with 2013 reactor operational data.
Ratio of expected reactor Low Energy Region and geoneutrino signal (RLER/G)
The table summarizes the predicted reactor signals in the full energy region R and in the low energy region RLER, together with the geoneutrino signals G [Huang et al. 2013] and the ratios RLER/G at current and proposed neutrino experimental sites, obtained with 2013 reactor operational conditions.
