Accreditation
• In July 2016 Environmental
Protection Agency extended its
accreditation for gamma
spectrometry in soil and bottom
sediments in accordance with
standard ISO 18589-
3:2015 Measurement of
radioactivity in the environment
-- Soil -- Part 3: Test method of
gamma-emitting radionuclides
using gamma-ray spectrometry

Conclusions
• Data reporting
– Excellent (considering the relatively short time better than
expected)
– The reporting ratio is high: more than 90%
– The communication (against the holiday season) was very active
15.8
• Performance
– Excellent for all of the analyte (MARB)
5.3
– Several cases the uncertainty budget
should be revised
– Mainly the reported uncertainty
is underestimated
– The detection limit have been reported 78.9
by 92% of the laboratories
Slide from presentation prepared by S. Tarjan and TEL Staff A W NDecommissioning of Ignalina NPP
• Nuclear facilities under
construction or planned:
Nuclear facilities at
Ignalina NPP site – Second spent nuclear fuel dry
(existing, planned, or
under construction) storage facility (project B1;
~3/4 of INPP inventory) – hot
trials are ongoing
– New solid radioactive waste
treatment and storage
facilities (project B3/4) -
under commissioning
₋ Landfill repository for short lived very low activity radioactive waste
– construction licence 2015
₋ Near surface repository for short lived low and intermediate activity
radioactive waste – under licensing for construction
HELCOM MORS EG 7/2017, 2-4 May 2017, TallinnNew interim spent fuel storage
facility
– On 2016-09-20, State Nuclear Power Safety
Inspectorate (VATESI) issued the operating
licence for new (second) Interim Spent Fuel
Storage Facility of Ignalina NPP
₋ Spent fuel will be stored in specifically designed casks
CONSTOR®RBMK1500/M2. INPP plans to store about 190
casks with about 16000 spent fuel assemblies during a period of
50 years.
₋ Operating license allowed INPP to start Hot Trial tests with 10
new design casks. During the tests, the casks will be loaded
with spent fuel and moved to the storage facility.
₋ The results of successfully performed tests will lead VATESI to
grant a permission for facility commercial operation. INPP
have plans to move all spent fuel to the new Interim Spent Fuel
Storage facility until the end of 2022.
HELCOM MORS EG 7/2017, 2-4 May 2017, TallinnVisaginas NPP project
• In the process of ongoing procedure of renewal of
the National Energy Strategy of Lithuania, on 24
November 2016, the Ministry of Energy of the
Republic of Lithuania approved the
“Recommended Key Guidelines of the National
Energy Strategy of Lithuania” .
• In addition to other energy policy matters, the Guidelines also address the
issue of the VNPP project. Item 7.13 of the Guidelines provides as follows:
“7.13. Freeze the Visaginas Nuclear Power Plant (VNPP) project until the
time when it becomes cost effective, regarding market conditions, or
becomes necessary, having regard to the circumstances of security of
energy supply.”
Therefore, development of Visaginas NPP project is currently suspended.
HELCOM MORS EG 7/2017, 2-4 May 2017, TallinnBelarusian NPP
• Lithuania is against Belarusian NPP in general
• The main reason for that is less than 50 km distance from
Vilnius, the capital of Lithuania
• However, the development of this project is going forward,
the beginning of exploitation is planned for 2019. So
Lithuania raises questions to Belarus and shows its concern
to this project
HELCOM MORS EG 7/2017, 2-4 May 2017, TallinnBelarusian NPP
• In 2016 Lithuania and Belarus started bilateral meetings
for discussing of technical aspects of Belarusian NPP
project (including safety, independence of regulator,
protection of environment, discharges, etc.). Two meetings
took place:
• 1. 21-22 of June 2016 in Vilnius
• 2. 13-14 of September 2016 in Minsk
• Not all question were discussed, additional meeting (s) are
foreseen
• 3. in 2017 in Vilnius
• 4. ???
HELCOM MORS EG 7/2017, 2-4 May 2017, TallinnArticle 35 Euratom verification
Dates - 29 November – 1 December 2016
Scope of verification - National environmental radioactivity
monitoring network (Vilnius region):
Verification of the laboratories involved in the monitoring
programmes
Verification of arrangements for monitoring radioactivity in
the environment
Verification of the automatic monitoring system data centre
Verification of some stations of the new national monitoring
system for environmental radioactivity
Verification of mobile monitoring systems
HELCOM MORS EG 7/2017, 2-4 May 2017, TallinnModernisation of the network of automatic
gamma dose rate measurement stations
• Tender for purchase of 14 new gamma dose rate stations took
place in July; evaluation of presented proposals is done, but
financing is not currently approved.
• Procurement procedure for modernisation of 13 AGIR type
stations is started.
• IAEA expert mission for the evaluation the existing early
warning system of Lithuania, identification of the needs for
upgrading the early warning system and providing
recommendations for effective design and operation of the
upgraded early warning system, including data sharing at
national and international level took place in Vilnius on 24 – 28
of November 2016.
