Yucca Mountain: Can the US Finally End

the $12 Billion Impasse?

NucNet | Page 282

A US federal advisory panel recently took a step in

what could be a lengthy process to determine if a

deep geological nuclear waste repository should

finally be built at Yucca Mountain, a project that has

been on the drawing board since the 1970s at a cost

of around $ 12 bn (€ 9.7 bn).

Detective Application Security Controls

for Nuclear Safety

Deeksha Gupta, Karl Waedt and Yuan Gao | Page 285

The current Draft Nuclear IEC 63096 New Work

Item Proposal (NWIP), a new downstream standard

of IEC 62645, distinguishes between preventive,

detective and corrective security controls. The focus

of this paper is on resilient detective cybersecurity

controls that are needed especially for high security

degrees in the context of Advanced Persistent

Threats (APTs). The approach is fully in line with

Nuclear IEC 62859 that provides requirements

on coordinating safety and cybersecurity. The

recommendations on separating selected detective

security controls from the process control software

can be achieved by avoiding an increased complexity

and the possibility of retroactions of security

measures on safety related functionality.

General Data Protection Regulation (GDPR)

of the European Union – What Had to Be

Considered until 25 May 2018

Stefan Loubichi | Page 289

With the General Data Protection Regulation

( GDPR) of the European Union there will be the

beginning of a new chapter in history of data protection.

With the beginning of May 25, 2018 we will

have harmonized regulations in the European

Union. With penalties up to 20 million euros and

imprisonment up to 3 years, the data protection will

have a high priority in future. In this essay we

present the subject-matter and objectives, material

and territorial scope and the principles relating to

processing of personal data. The GDPR presents a

sustainable change in data protection. For years to

come, this will lay the foundation for trust in data

protection in Europe.

The New Radiation Protection Law:

May Makes Everything New?

Ulrike Feldmann | Page 296

Last summer, a radiation protection law was

launched for the first time in Germany. The Federal

Government was obliged to implement the revised

version of the basic European radiation protection

Directive and emphasised the importance of

radiation protection by ranking it into a law. This

law now has to be filled with “life” at the level of

ordinances, so that it can be applied in practice. The

deadline for implementing the Directive always

expired on 6 February 2018.

Continuous Process of Safety Enhancement

in Operation of Czech VVER Units

J. Duspiva, E. Hofmann, J. Holy, P. Kral

and M. Patrik | Page 299

A continuous process of a safety enhancement of

VVER units in the Czech Republic is briefly described

including a presentation of important milestones

and examples of particular safety measures already

implemented. A special attention is given to the

evaluation and implementation of safety measures

following stress tests recommendations and R&D

activities supporting this process. As examples an

implementation of the “design extension condition

without core melt” concept and various activities

related to severe accident mitigation strategies are

presented in the more detailed way.

Applications of Underwater-Robotics

in Nuclear Power Plants

Gunnar Fenzel, Dr. Dietmar Nieder

and Alexandra Sykora | Page 305

Cutting and packing of the reactor pressure

vessel (RPV) is one important step during decommissioning

of nuclear power plants. Therefore, it is

the objective of the research project Automated

Cutting of Reactor Pressure Vessels Internals Using

Underwater-Robotics (AZURo) to (semi-) automate

frequently repeated activities by an underwater


This joint research project was sponsored by the

German Federal Ministry of Education and Research

(BMBF). It was executed together with Fraunhofer­

Einrichtung für Gießerei-, Composite- und Verarbeitungstechnik

IGCV. The project AZURo started in

2012 and was finished in 2016.

360 Degree Area Atlas

in the Biblis Nuclear Power Plant

Jürgen Kircher | Page 308

The operation and the dismantling of decommissioned

nuclear power plants is a technical

challenge. It must be fully documented. A helpful

tool for operation and dismantling is the so-called

spatial atlas. The atlas provides the rooms in the

nuclear power plants in high-resolution 360° HDR

images and technical circumstances resulting

therefrom may be deduced.

ELINDER – European Learning Initiatives

for Nuclear Decommissioning and

Environmental Remediation

Pierre Kockerols, Hans Günther Schneider

and Daniela Santopolo | Page 309

The decommissioning of nuclear facilities is an

industrial activity that is expected to grow worldwide,

creating many attractive career opportunities.

European industry has acquired know-how and

today Europe can position itself at the top level in the

world decommissioning market. However, in view of

the expected expansion of the activities, efforts are

necessary to share and enhance the underpinning

knowledge, skills and competences and to ensure the

availability of the necessary workforce in the future.

JRC and partners in the EU decommissioning field

have launched a project to consolidate and improve

existing training programmes. The joint training

programme project is called ‘ELINDER’ (European

Learning Initiatives for Nuclear Decommissioning

and Environmental Remediation) and is implemented

from 2018 onwards.

The New CASTOR® geo – A Comprehensive

Solution For Transport and Storage of Spent

Nuclear Fuel, MOX and Damaged Fuel

Linus Bettermann and

Roland Hüggenberg | Page 312

Dry interim storage has become a common solution

for the disposal of spent fuel in recent years worldwide.

However, in particular the complete defueling

of NPP prior to decommissioning and dismantling

will dramatically increase the demand especially for

non-standard fuel. Here the new dry storage system

by GNS is presented for international markets with

its capability to also store MOX and damaged spent

fuel. The new CASTOR® geo cask system is a product

line based on standardized modules and components

featuring different cask dimensions and

basket designs.

Optimal Holistic Disposal Planning –

Development of a Calculation Tool

Johannes Schubert, Anton Philipp Anthofer

and Max Schreier | Page 316

The expected volume of radioactive waste from

dismantling of nuclear facilities in the forthcoming

scope and the opening of the Konrad disposal

requires an optimised planning of the removal of

radioactive waste. For the treatment of radioactive

raw waste, with negligible heat generation, different

conditioning processes are available. Thereby different

waste volumes and masses with different properties

can result even from the same raw waste. An

optimisation can be realised. The complex process

can be carried out by a calculation tool.

Scope for Thermal Dimensioning

of Disposal Facilities for High-level

Radioactive Waste and Spent Fuel

Joachim Heierli, Helmut Hirsch

and Bruno Baltes | Page 319

The objective of final disposal of high-level radioactive

waste in deep geological formations is to

isolate the radionuclides from the accessible

biosphere for a sufficient period of time. To achieve

this, both the functionality and the integrity of the

disposal system must be assured under ambient

conditions that

depend both on the geological environment and

on engineering choices taken in the planning

of the facility. In particular, the amplitude of

the transient temperature increase caused by the

release of nuclear decay heat in the disposal area

is scalable through design strategies and thermal


Heavy Ions Irradiation as a Tool

to Minimize the Number of In-Pile Tests

in UMo Fuel Development

H. Breitkreutz, J. Shi, R. Jungwirth,

T. Zweifel, H.-Y. Chiang and W. Petry | Page 325

Irradiation with heavy ions from an accelerator

source is an increasingly often used tool to quickly

reproduce and simulate certain effects of in-pile

irradiation tests, avoiding the complexity and high

costs of handling highly radioactive samples.

At the Maier-Leibnitz Laboratorium (MLL) of the

Technische Universität München (TUM), swift

heavy ions have been applied in the development of

Uranium-Molybdenum (UMo) based research

reactor fuels for more than 10 years. Since then, the

technique has been advanced from feasibility

over qualitative analysis to quantitative prediction,

including fission gas implantation.

Nuclear Newcomer Turkey and ‘Comeback

Kid’ Japan Show the Way Ahead

John Shepherd | Page 354

Around 20 years ago there was one story that

cropped up again and again: “Forget that – it will

never happen, they’ve been talking about it for

years.” The subject was Turkey and its desire to

build the country’s first nuclear power plant. But

today, first safety-related concrete was poured and

finally marked the start of construction of Turkey´s

first nuclear power plant in Akkuyu, with four units

planned. There was progress too on the international

nuclear front from Japan, where KEPCO

confirmed the restart of the third unit of its Ohi

nuclear power plant.
