Selection of Roof Casting Formwork Systems for the Bird
Island Project: Case Study.
The paper illustrates the complexities involved in the selection and deployment of a formwork system through a study of
the concrete formwork selection on the Bird Island Flats Tunnel project. This $290 million project was a part of the Central Artery/Tunnel
project in Boston, Massachusetts. Because the conventional shoring methods could not produce the output needed to meet the project
schedule and budget, the contractor solicited proposals from formwork manufacturers and chose the system from CONESCO Industries.

How Advanced Simulation will Impact the Offshore Industry both Now and in the...Altair
The easy days of Oil and gas extraction is over, and the ability to extract Oil and Gas from harsh enviornments is very dependent on the ability to overcome technical challenges through the use of advanced numerical analysis and simulation. Technical challalenges currently faced in the industry include High Pressure High Temperature (HPHT), Utra Deep Water (UDW) with water depths greater than 10,000 ft, and the Arctic with potentially 20% untapped hydro carbon reserves. These technical challenges are overcome through more use of advanced analysis and simulation, and this allows cost effective solutions to be obtained.
Also the Industry is currently being challenged by a low oil price, and lots of companies are forced to look at cost and schedule. This as a result, allows the opportunity for the use of advanced analysis to help solve Engineering challanges in an efficient manner and save potentially millions of dollars in the Engineering. The ways that this is undertaken is presented and discussed.
There are different types of Analysis simulation used in the Offshore Industry, for example FEA, CFD, Coupled Analysis etc. Also computer power is ever increasing in compuational efficiencies, and novel methods, such as the use of Cloud computing, has had a big impact on the way that analysis is undertaken. These different methods of software and hardware are discussed in relation to the Offshore Industry, and an indication is given in to how these methods will affect the Industry in the future.

2015 Foundations for larger and deeper Offshore Wind MEC Intelligence
For offshore wind farms installations, foundation selection plays an important role in the overall concept design as there are large financial implications attached to the choices made. Foundation costs are primarily driven by material & installation costs and have been considered in this report.
New foundation designs have lower costs as turbines become larger and installed in deeper sea. For instance, 6 MW, new foundations are ~4-20% lower in material cost when compared to monopiles & jackets while for turbine sizes 8 MW and larger, new designs reduce the cost by ~21-24%. Cost reduction potential of 5-15% is observed for foundations at selected 5 farms in Europe. However, developers need to manage risk and other associated premium costs with appropriate contracting.
This reports presents detailed and fact based evaluation of foundations technologies for larger & deeper offshore wind farms. It also offers an evaluation of innovations that could assist in driving down the cost of the installation of foundation for offshore wind farm operations.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

AERB Auditorium,Niyamak Bhavan-B Mumbai .
2. An Overview of Technology
Development
(Posers & Challenges for Structural
Analysis Community)
SF Vhora,ED(TD),NPCIL
9 May 2018
3. R&D Facilities
R&D activities related to following promote
structural integrity of NPP Structures, Systems
& Components.
• Passive Decay Heat Removal System
• Containment Spray System
• Passive Catalytic Recombiners
• Containment Filtered Vent System
• Pressure Tube burst test studies
4. Remote Tooling
• Remote Tooling activities such as following
promote structural integrity of critical
components and equipment:
• BARCIS Inspection
• Steam generator inspection and debris removal
• Heat exchanger in-service inspection
• Installation, Repair & Refurbishment of reactor
component
• Use of automated welding
5. Indigenization
• Indigenisation promotes structural integrity as
critical raw materials such as steam generator,
pressurizer forgings, end shield tube sheet
plates get manufactured within the country
under regime of strict NPCIL QA coverage.
6. Construction Time Minimization
Certain type of modular construction has
tendency to create conditions which enhance
quality of construction and therefore
structural integrity.
• Preformed Ring Liner, Structural steel floor &
Integral dome modules have proven this
• ESCIA is one prime example of this
• New approach to Speedy fabrication is arrived
8. Nuclear Industry Biggest Challenge
• Economic viability of Operating Units & New
Projects in the face of disruptive Renewables
technological & economical advances
• Operating Units – Major Issues
- In service health of critical components
- Plant Life Extension
New Projects :
- Issues coming up during construction which
can significantly delay
9. Regulatory review of Issues during
Project Construction
• Experience world over seems to indicate that the delay
caused by incidents which ultimately impact structural
integrity e.g. Concrete quality, weld quality, Cal vault
• Examples of EPRs at OL3 & FM3 , AP1000 at VC Summer
show huge financial implications & bankruptcies
• Average Construction time of India (9.0y) is about 3-4 years
greater than Korea (5.3y)& China(6.0y)
• For 700 PHWR certain proposed modifications are
worrisome as to further erode economic viability
• Therefore ready analysis capabilities in place with full
models could be a great investment as a time saver
• This Workshop can promote such an approach
10. Operating Units
KAPS-1,2 Pressure Tube issue
• Possibility of Combination of factors has not
been explored
• In-situ Pressure test after defueling – should it
have been considered?
• Why did we not think to pressure test taken
out PTs earlier?
11. Operating Units – World Over
• Wide variation in approach to life extension
• USA NRC appears to have consistent approach
• Most US plants life extended up to 60 y & thinking of
80 y
• CANDUs in Canada – mostly extending channel life has
given a breather – NPCIL needs to learn from this
approach – collaborate on channel issues
• Elsewhere picture is confused
• Armenia – shutdown after earthquake – decision
revoked when power crisis
12. R&D/TD Perspective based Proposal
• Since NPCIL is going to construct 12 units need to anticipate
likely issues which may crop up impacting structural
integrity aspects
• If two full independent models of RB can be made ready for
taking up analysis & providing results within days could
have a huge commercial benefit
• Some physical model of RB & Internals can be thought of &
tested on shake table
• Impact analysis for assumed RB internal structure & ICW
may show there may not be much of concern
• This workshop may consider proposing such an approach
• R&D/TD funds could be made available
13. Engineering Thinking & Trends which impact
safety & economic viability of 700 PHWRs
These pertain to structural integrity issues in general
Potential for erosion:
• RB diameter increase & spacing increase
• Replacement of structural steel floor with concrete
floor
• PDHRS removal
Potential for helping:
- Adoption of PRL, SSF&HA, ESCIA & Dome with rebars
also preinstalled
- Built-in shuttering cum EP in some parts of RB
- longer term – revert to structural steel option ?
16. Presentation focus on Major Modular Construction
techniques & New approaches to speed up
fabrication of critical path activities.
A Nuclear project has Nuclear Island, Conventional
Island & Balance of Plant.
Critical path goes through Reactor building.
Benchmarking has established that project completion
can happen from FPC to Commercial in about 50 to
60 months.
Adoption of New Technologies & Excellence in Project
Execution can achieve this.
(Implementation of Modular Construction Ideas were
preceded by Structural Analysis by DTD,NPCIL)
18. Preformed Ring Liner (PRL) Concept Adoption
Backing
Truss Crane hook location
Wire Ropes
Spider
Slings
PRL
Lesser congestion in IC wall resulting in simplified
construction due to elimination of the Out of plane
portion of backing truss from liner.
Majority of fabrication can be done at ground,
resulting in good quality weld leading to better leak
tightness in liner.
Availability of tower crane for other works improves.
More parallelization in construction work can be
realized leading to substantial construction time
minimization.
25. ESCIA
• This idea has the potential to radically change the way NPCIL
Builds new project.
• Concept arrived can eliminate 12 to 16 months from 700
Project schedule
• Is symbolic of addressing the only weakness of NPCIL – timely
execution of projects.
• Adopting this would also call for different approach to Supply
Chain & Project Execution.
26. Technical feasibility of ESCIA
• Feasibility established through detailed study of options
Scheme considers following steps
• Makes use of heavy duty crane to bring the assembly direct to FM vault
• Subsequently uses the current method of sliding the assembly in place
• Does not call for stoppage of civil construction on North side
• Calls for minor change in design of End Shield Calandria side flanges to be made
similar to FM side Flanges.
Why Confident? Successful Implementation of Major Modules PRL & SSFA has been
carried out, Dome in planning stage
27. TECHNICAL FEASIBILITY OF END SHIELD & CALANDRIA INTEGRATED ASSEMBLY (ESCIA)
SEQUENCE OF
ERECTION
28. TECHNICAL FEASIBILITY OF END SHIELD & CALANDRIA INTEGRATED ASSEMBLY (ESCIA)
PROVISION FOR
FULL
REHEARSAL
29. These are preliminary conceptualization views subject to further
detailing & refinement .
ESCIA Preliminary Design of Workshop
31. Summary
Technology Development Activities of NPCIL are:
• Contributing to Safe & Reliable Operation of NPPs.
• Addressing Supply Chain constraints
• Evolving Methodologies for Quick Construction
• These will provide Robust, Economical & therefore
Export worthy PHWR Technologies for the future
sustainability of the planet.
