Construction Inspections - STUK objectives
•
Inspections during construction can be divided to two categories
– Inspections during construction on
structures and components
• To verify QA and QC
results and activities of
manufacturer, vendor and
licensee - product
conformity
• Defined in regulatory
guides
• Inspection organizations
used in lower safety
classes
– Inspections on licensee’s
performance within the Construction
Inspection Program
• To verify the adequacy of
project management, safety
assessment, QA/QC
programmes, etc. performance conformity

Principles for Regulatory Oversight during construction
•
Review and approval of detailed design documentation for systems structures and
components (SSCs)
– Before start of construction or manufacturing
•
•
•
Oversight of and inspections on manufacturing and construction to verify product
conformity (QA and QC activities of manufacturer, vendor and licensee)
– Resident inspectors on site (complemented with staff from HQ)
– Regular visits at the component manufacturing sites
Assessment of licensee performance to verify the adequacy of
project management, safety assessment, QA/QC programmes, etc.
– Inspections within the construction inspection programme
– Quality of the submitted regulatory documentation
– Resident inspectors at site
Assessment of the performance of the parties responsible for
design, construction and manufacturing
– Audits, inspection visits, manufacturing and construction
oversight, meetings - (CIP)
– Have to learn more details and neesds on the job training!!!

Construction Inspection Programme - Goals of the
CIP inspections
– Licensee has adequate
resources
– Licensee has control on the
project (site, manufacturing,
vendor, subcontracting etc.)
– Licensee has systematic
processes and procedures in
place for processing safety
issues (design review and
approval process)
– Licensee’s QA/QC programmes
are functioning ensuring
performance and product
conformity
– Licensee is getting prepared for
commissioning and operation of
the plant

Construction Inspection Programme - General
arrangements
– An overall inspection program for the construction has
been established defining inspection areas and
responsibilities (YTV 4.6.1)
– More detailed six-monthly ( VARANS – annual plan)
plans for execution of the program will be established
• Inspection areas and main topics
• detailed schedule for inspections
• enables adjustability to project schedule and phasing
(proactivity)
– 10-15 inspections annually
– Inspection team typically 2-4 persons – resident inspector
usually participates
– Duration of the inspection typically 1-2 days.
In General: The same manner for VARANS conducting
ispections. (DQH)

Construction Inspection Programme - Inspection areas
1/2
• Main operations such as:
– management and processing of safety matters
– management system and main processes
– administration of resources and skills.
Need in practices (DQH comment)
• Procedures for operating processes and records (by
technical area if necessary), such as:
–
–
–
–
–
–
project quality assurance
operating personnel training
utilisation of Probabilistic Risk Assessment
inspection procedures
document management
radiation safety.

Construction Inspection Programme - Inspection areas
2/2
• Inspection of the following issues is generally combined
with inspections carried out under the Operating
Inspection Programme:
–
–
–
–
emergency response arrangements
arrangements for security
fire protection
processing of wastes.
• In addition STUK can also focus inspections on other
issues/subject areas at its discretion
– STUK can also carry out inspections without prior
notification to the licensee. (Varans can do the same with
some limitations!)

Construction Inspection Programme – six-monthly
plan
• STUK’s regulatory control project manager drafts a sixmonthly plan (usually Varans Chief inspector drafts annual
inspection plan-DQH comment)
– drafting of the six-monthly plan is based on the proposals of
the sub-project managers responsible for inspections
– Project Manager ensures that two consecutive six-monthly
programmes covers all of the inspection areas
– the plan presents the topic of the inspection, the week the
inspection will be carried out, the person responsible for the
inspection as well as the resident inspector appointed to the
inspection
– the plan is approved by Nuclear Reactor Regulation’s
Director.
– the plan must be ready a month before the start of each
period and is submitted to licensee’s contact person by
email. (almost the same in Varans)

Construction Inspection Programme – carrying out
the inspection
•
The inspection is carried out in accordance with the inspection plan
– the inspection plan is gone though at the start-up meeting and the practical
arrangements during the inspection are agreed. Deviations from the
inspection plan are to be shown in protocol (lack in Varans
procceduress)
– during the inspection, people can be divided into groups and hold joint
meetings for the inspection group
– the objective of the inspection is to assess the appropriateness and
adequacy of the licensee’s procedures in respect of the inspection area
and the requirements stipulated
– The methods of assessing procedures are interviews, monitoring the
operation in practice as well as STUK’s own tests for the focus area.
STUK’s assessment of the procedures must always be based on an
assessment of their application in practice.
– The inspection findings and the consequent requirements are recorded in
the TARKKA system and are explained at the final meeting by the person
responsible.
– The requirements are monitored and closed in the TARKKA system.

Experience - Construction Inspection Programme
• Assessment of licensee performance to verify the adequacy of
project management, safety assessment, QA/QC programmes,
etc.
 possibility to evaluate and influence timely on licensee’s
performance, organisation, management, resources,
processes
– basis of requirements for inspection areas not as well
defined as for SSCs (subjectivity of assessment)

Example - results of OL3 Construction Inspection
Program in 2011
•
STUK performed 14 inspections in 2011 under CIP and gave 35
requirements. General findings were
– Project has set in force number of application notes that differ from
accepted project procedures. TVO don’t have practices or guidance
how to introduce abnormal procedures or make the safety evaluation
of the consequences.
– TVO has delivered design documents to STUK even there is
remarkable technical or quality issues open between the consortium
and TVO. Content of TVO’s cover letters have been insufficient.
– When evaluating the level of the safety culture at the site, TVO don’t
utilize all possible sources like non-conformances or events at site
(but more rely on surveys).
– Control of the open issues (from manufacturing, installation phases)
is insufficient – project don’t have usable common management
system for open issues.
– AREVA don’t have human resources to audit contractors at site.
