In this report, the contents of the 2018 Internationl Atomic Energy Agency Technical
Meeting on the International Network of Nuclear Reaction Data Centres held at theGlobal Centre for Nuclear Energy Partnership, Bahadurgarh, India from 1 to 4 May2018 are discussed. This meeting aims to discuss the various statistics, manuals anddictionaries, compilation needs, quality control, coding rules as well as software anddissemination related to the EXFOR compilation.

1Introduction

The 2018 - Internationl Atomic Energy Agency (IAEA) Technical Meeting on the International
Network of Nuclear Reaction Data Centres was held at the Global Centre for Nuclear EnergyPartnership (GCNEP) in Bahadurgarh, Haryana, India from 1 to 4 May 2018 [1]. The meetingsof this network are held every year and with full meetings involving center heads and technicalstaff bi-annually. The 2018 meeting was attended by about 20 participants representing different
Centers from the eight Member States (China, Hungary, India, Japan, Korea, Russia, Ukraineand USA), two International Organisations (NEA, IAEA) and also a participant from Kazakhstan(for participant list see Appendix I). Main topics of the present meeting were annual reports ofdifferent centers, various statistics, manuals and dictionaries, compilation needs, quality control,
coding rules as well as software and dissemination (for detailed program see Appendix II). The
report is organized as follows: section 2 lists the objectives of meeting. Section 3 describes themain topics of the Agenda. Section 4 presents the closing of the meeting. Finally, section 5 reportssummary.

2Objectives• Annual reports of Nuclear Reaction Data Centers.
• Various statistics, manuals and dictionaries related to EXFOR-compilation.
• Quality control, coding rules, software and dissemination.

Main Topics of the Agenda

3.1

Opening

In the opening session, A. Saxena, Head of Nuclear Physics Division of Bhabha Atomic ResearchCentre (BARC) welcomed the participants, and followed by the self introduction of all the participants. The election of the chairperson was conducted and A. Saxena (BARC) was elected asthe chairperson.

3.2Progress Reports

Progress reports from all 13 attending centers were presented by center representatives, where they
discuss their staff strengths, compilation, dissemination and other nuclear data related activities ofinterest to the network.

3.3

EXFOR General• N. Otsuka reported the statistics of transmissions, journal scanning and preliminary tapechecking. He reported that 521 new entries and 996 revised entries have been newly finalized
since the last NRDC meeting.
• N. Otsuka presented his analysis of compilation time (time of transmission - time of publication) for seven selected journals. Average time interval between the preliminary and finaltransmission, for the period from May 2017 - April 2018, for all centers was also reported. Itwas advised that this time not to be longer than reasonable time i.e. 2 months.
• N. Otsuka reported there was neither a comment nor a proposal on the draft of the EXFOR
reference paper (WP2017 − 07) from the centers until the end of 2017. It was concluded thatthe ND2013 article (Nucl. Data Sheets 120(2014)272) should be cited by EXFOR users.

3.4

Manuals and dictionaries

N. Otsuka (on behalf of N. Soppera) presented the result of assessment on ambiguous REFERENCE keyword coding form. It was concluded that the absence of the page number must beindicated by including a separating comma for the reference types A, B, C, J and K.

3.5

CINDA

N. Otsuka (on behalf of V. Zerkin) reported that automatic updates of CINDA database using
the EXFOR and NSR databases have been performed 12 times (from May 2017 to April 2018).

3.6

EXFOR compilation needs

N. Otsuka presented a summary of the EXFOR completeness checking for neutron, proton andalpha induced reaction data performed by V. Semkova. It was reported that at least 3% of proton
induced reaction experimental works and 20% of alpha induced reaction experimental works arestill missing in EXFOR.

3.7

EXFOR quality needs

N. Otsuka reported the situation of english translation of the Russian articles published in FCY,KSF,and ZTF, and asked the originating centers to add the bibliographies of English translations
missing in EXFOR.

3.8

EXFOR coding rules

1. N. Otsuka proposed two points as follow:• Shall we introduce a new modifier when the quantity is for a natural sample divided by
the isotopic abundances of the target isotopes contributing to the reaction, or use theexisting generic modifier FCT ?
It was concluded to use FCT without introducing a new modifier.
• Shall we use the REACTION sum when the quantity is partial for unresolved two secondary energies from several product nuclides ?
It was concluded that the process code X will be used without REACTIONsum.
2. N. Otsuka also proposed• Need of indicating a fragment separator for separation of reaction products under DETECTOR ?
It was accepted by all.
• Need of description for the use of a secondary beam originated from projectile fragmentation under INC-SOURCE with a new incident source code FRAGM ?
It was also accepted by all.

3.9Tools for Compilation and Dissemination

1. S. Taova presented that the EXFOR Leaflet was revised as per comments from the othercenters since the last meeting. It was proposed that for publicizing the EXFOR, leaflet canbe distributed and displayed at relevant conferences and notice boards.
2. G. Pikulina reported the new upgrades in InpGraph. It is possible to generate DATA section
and COMMON section of a subentry completely by the digitizer.

3.10

Other topics covered• T. Zholdybayev reported progress in EXFOR compilation at his institute. He discussed
the possibility of digitizing data from the the preprints and logbooks for updating the seven
existing EXFOR entries.
• B. Pritychenko provided a review of compilation effort in the Area 1. He also explored theEXFOR compilation HISTORY field for 2012-2016 time span, and provided a rough estimateof individual productivities in the NRDC network.

4ClosingN. Otsuka proposed the dates and places for the next technical NRDC meeting (Vienna, Austria,
9 to 12 April 2019) and the next full NRDC meeting (Vienna, 2nd quarter of 2020), and they wereapproved. A. Saxena made closing addresses. S. Taova and N. Otsuka thanked A. Saxenaand D. Raj for their excellent local arrangement.

5Summary

The results of the discussions were summarized in 23 conclusions and 83 actions. For details see
the full proceedings of the meeting [2].
