1. New G4 LW and G5 SCWR SMR Start-Up BNT-project development:

 

The era of Naval nuclear propulsion (NNP) systems on board ships is comparable in human importance to the advent of jet aircrafts or spaceship flights. Small nuclear reactors (SMR) have been successfully used in the Navy in different countries for almost 60 years and have shown to be equipment that is reliable and technologically advanced. For various reasons, the expertise gained by the military usage of nuclear reactors can now benefit civilian usage of nuclear reactors.

Over the last ten years, different groups of designers and scientists from various countries have been working on the development of several dozen projects for SMR. The greatest success has being achieved in the United States and Russia. But the developers within these countries are moving forward in various ways. In the U.S, designers are creating new projects using only development based on civil projects. In the past, Russian designers actively deployed their development experience for the Navy. For many objective reasons, the proposal of the Russian developers is more adapted to modern technologies and the overall validation of tests, inspections and maintenance of reactor prototypes, nuclear submarines and nuclear ice-breakers (NB).
The main reason for such progress is the partial declassification of naval reactors for civilian ships (see for for example here) and access to information on the operation of military facilities as well as the development of civil reactor designers of military equipment.

Today we are faced with a unique situation where Russian civilian development is ahead of U.S. development by approximately 10-15 years. At the same time, the market for SMRs is in its infancy, and the prospect of competing for a position in this new market is real. Thus far, the market does not have any major players, but the rules of play and the situation can change very quickly.
At this point, the projects of major U.S. companies (Westinghouse, B & W, Holtec etc.), must work within political boundaries. However, the U.S. market may see radically new and promising projects focused on the use of local industrial resources and expertise available in an engineering and scientific environment. The primary goal behind such a project is to combine skills and recourses optimally, and to get the most technically sound product on the market quickly (see updated draft Presentation here: NuCore design approach-I 09-13)

As result, we can expect significantly lower financial expenses in:

  • Financing needs
  • Total capital costs less them 3,000…4,000 USD USD/MWe (compare to 5,000 and above from other competitors)
  • Manufacturing costs
  • Components transportation costs
  • Construction costs
  • Operating and maintenance costs
  • Decommission costs.

This resulting opinion is based on the skills, experience and long time collected information, which has been analyzed over the last 15 years yeas, as well as the personal experience, design skill, conceptual development and modern creative direction.

 

 

 

 

2. LW SMR round table and open discussion (Corvallis, OR USA end of August 2013):

 

NuCore.US Presentation plan (not related to Presentation content directly): “Few words about Gen-4 and future Reactors development”: 

1. (short – pie diagram) From worldwide NR fleet to all types of small reactors (naval (US, SU-Rus, etc) and/or researches)

2. (short – diagram) From all Generations (from 1-st to 5-th…) to all different SMR types observation (LWR, LMR, SCWR, HTGR etc), different approaches and perspectives. Large LWR reactors have no chance to be advanced today from safety point

3. (short – opinion) LW SMR as perspective only for next 40-50 years, and as base for future small SCWR and LMR systems technology development, other preferable types are: …

4. (short – list of the reasons) SMR projects development (different reasons/causes for different countries) overview

5. Opinion about general design solutions and development perspectives for current projects (projects, designers, design) from cause of interactions Thermal-Energy in the core generation and Mass-flow, and FI vs CHF, etc

6. Technical problems and design solutions cause for future operating and operational problems. Reactor (core, RV, SG) – from power generation to heat remove main components/processes scheme

7. Few different way to improve LW SMR design (fuel (composition, matrix, cladding), core, SG, PCS circuit, systems, safety and as result operating algorithms and conception of operating (procedures), economy etc.). What is the best choice? Ch-inertial, but very-very low-conductivity or fast heat sunk from Core?

8. New and/or advanced fuel and core current study (directions: F-composition, FE-cladding materials, core design/geometry)

9. Very few introductory words about ATR capability for core and fuel future researches (not presentation, but …)

(NuCore OSU INL SMR 10-13 to be presented 08/2013 in NuEn Conference, draft)
