Two important meetings related to NEA nuclear safety activities
were held at the end of 1999:
The 11th Meeting of the Committee on Regulatory Activities on November 29-30 1999, and the 27th Meeting of the Committee on Safety of Nuclear Istallations (CSNI) on December 1 - 3, 1999.
The main purpose of both meetings was to review the activities
carried out by these Committees in 1999 and to approve the activities
proposed for the year 2000. In total more than 40 reports and technical
opinion papers were produced and a number of workshops were held in
this area in 1999.
One of the most important outcomes of the CSNI meeting was the approval of the CSNI Strategic Plan www.oecd-nea.org/nsd/docs/2000/csni-r2000-3.pdf . The reasons for developing the Plan were to ensure that the work of the CSNI is aligned with the NEA Strategic Plan, and to maximise the efficiency of its work in view of the decreasing R&D budgets in Member countries. The basic objectives to be achieved by the plan are better top-down direction of the programme of work, and maintenance of an effective network of technical experts.
The plan specifies a new CSNI mission and identified the
strategic areas of future activities. In addition, the plan included a
number of organisational recommendations, including CSNI restructuring.
Both Committees approved a number of a workshops and seminars to
be organised in future:
· CSNI Workshop on Instrumentation and Monitoring of
Concrete Structures, Brussels, March 22-23, 2000 (see below)
· CSNI Workshop on Advanced Thermal-hydraulic and
Neutronic Codes, Current and Future Applications, Barcelona, April
· Safety of the Nuclear Fuel Cycle, 29th to 31st May 2000,
Japan, Joint Workshop with CSNI, CNRA, CRPPH, and NSC. See www.oecd-nea.org/nsd/reports/final.pdf
· CSNI Specialist Meeting on Safety Performance
Indicators, Madrid, Spain, October 17-19, 2000
· CSNI Workshop on Errors of Commission in Probabilistic
Safety Assessment, November 2000, United States
· CNRAWorkshop on Investing in Trust: Nuclear Regulators

A OECD Workshop on the Instrumentation and Monitoring of Concrete
Structures, sponsored by the Committee on the Safety of Nuclear
Installations (CSNI) of the OECD Nuclear Energy Agency (NEA), will be
held on 22-23 March 2000. The Workshop is hosted by
AVN/Belgatom/Electrabel/Tractebel and will take place at the offices of
NPP concrete structures have been built to provide significant
margins against the effects of accidental events. Instrumentation and
monitoring are the channels to assess their actual state and follow
their time evolution. The objective of the workshop is an assessment of
the capability of current instrumentation and monitoring systems to
describe the actual state of structures and detect ageing problems. The
workshop will focus on experience and detect trends for the future.
The Workshop will have three technical sessions devoted to
presentations of issues related to Instrumentation and Monitoring. They
will be followed by a fourth session devoted to a discussion of the
material presented and to the formulation of workshop conclusions.
Session 1 - State of the Art and Regulatory Considerations: The
objective is to emphasise difficulties encountered, evidence of
robustness, and recommendations for improvement and also to give a
regulatory perspective on Instrumentation and Monitoring of concrete
structure as part of safety assessments.
Session 2 - Detecting Ageing: Instrumentation gives valuable
information regarding the in-service performance of containments as
constructed which can be used to confirm the original design
assumptions and that their performance is as intended. Many
containments have shown some degradation during plant life, either in
the concrete itself or in the steel reinforcement or liner. It is of
primary importance that instrumentation should be able to detect ageing
problems and identify performance trends. Also of particular interest
are dynamic instrumentation relevant to ageing and non-nuclear
experience of instrumentation in large and complex structures.
Session 3 - Trends for the Future: This session will focus on
future developments in the Instrumentation and Monitoring field. Can
new technologies ( e.g. optic fibres) help with safety assessment? Can
instrumentation on real structures be used to validate Finite Element
codes? How best can we use monitoring in conjunction with periodic
Session 4 - Panel Discussion.

From 24-25 January, 2000 the Fourth Workshop on the
Pressurised Water Reactor
Main Steam Line Break Benchmark (PWR-MSLB-4) was held in Paris.
The benchmark uses plant data from the B&W TMI-1 reactor,
2772 MWt, about 900 MWe power, equipped with two Once Through Steam
Generators (OTSG). The general purpose of the activity is to reach a
common understanding concerning the coupling between thermal-hydraulics
and neutronics, with emphasis on 3-D modeling. The considered benchmark
was proposed and specified by PSU, who have co-operated with GPU and
NRC. The activity has been subdivided into three main phases:
1. analysis of the transient with a thermal-hydraulic system code
coupled to a point neutron kinetics model: the purpose of this step is
to reach an understanding of the problem among the participants with
reference mainly to the modeling of the system, including
interpretation of the supplied/available information;
2. analysis of the core performance only, when a 3-D neutron kinetic model is coupled with the thermal-hydraulic code: the main purpose is to evaluate the hypotheses at the basis of the coupling, e.g. looking at their impact on the results;
3. analysis of the entire system performance with the coupled codes: the purpose is to evaluate the importance of the 3-D neutronics modeling in the considered cases, and to establish realistic and assessed methods (i.e. inclusive of codes, nodalisations and use of codes) suitable for safety, licensing and design analyses.
The results of this study are being published in 4 reports.
A kick-off session was devoted to the new proposed BWR Turbine
Trip benchmark for further validation of coupled 3D core/plant system
codes. This benchmark problem is based on experimental data (Peach
Bottom). A first benchmark workshop dedicated to this benchmark is
scheduled for the 8-9 November 2000.

Prediction of Neutron Embrittlement in the Reactor Pressure
Vessel: VENUS-1 and VENUS-3 Benchmarks
This is the final report of two international blind intercomparison exercises performed to examine the current computation techniques used in NEA Member countries for calculating fast neutron doses to reactor components. arious methodologies and different nuclear data were applied to predict neutron dose rates in the Belgian two-dimensional VENUS-1 and three-dimensional VENUS-3 configurations for comparison with measured data.
This report provides the detailed results from the two
benchmarks. The exercise revealed that three-dimensional neutron
fluence calculations provide results that are significantly more
accurate than those obtained from two-dimensional calculations.
Performing three-dimensional calculations is technically feasible given
the power of today's computers.

Calculations of Different Transmutation Concepts: An
International Benchmark Exercise
The final report of the benchmark on different transmutation concepts has now been published. The benchmark investigates the physics of complex fuel cycles involving reprocessing of spent PWR reactor fuel and its subsequent re-use in different reactor types based on PWRs, fast reactors and an accelerator-driven system (ADS). This report gives the analysis of results of the 15 solutions provided (six for the PWRs, six for the fast reactor and 3 for the accelerator case).
As a follow-up to this benchmark, a further ADS benchmark is
being undertaken to resolve discrepancies identified in the present
benchmark (e.g., considerable differences in calculated initial k-eff
and burn-up reactivity swings). This benchmark can be extended later on
for more complex investigations such as beam trip transient behavior of
