On Yucca Mtn. and US Nuclear Energy

President Obama has chosen to direct the Department of Energy to abandon the Yucca Mtn. geologic repository for discarded nuclear materials.  In addition, President Obama has commissioned a two year ‘Blue Ribbon’ panel to evaluate alternatives and nuclear energy in general.  After a brief tour of the Hanford Nuclear Reservation in Souteastern Washington State , the panel provided a public forum for official and public input in Richland, Washington on July 14-15 .  The following is this author’s presentation at that forum.

Low cost energy brings improvements in quality of life to everyone.  We need to provide every avenue of access for the six criteria for successful energy systems:  abundant, reliable, dispatchable, responsive to need, compact, and economical.  All conventional systems, especially nuclear, have held up under all these criteria for decades.

Despite naysayers, nuclear energy has had a remarkable performance record, besting nearly all sources in these criteria except perhaps hydroelectric.   Fleet capacity factors are in excess of 90% and product cost competes favorably with coal.

At one time, nuclear energy growth in the US was common.  But a mix of political posturing on weapons proliferation, used fuel disposal, and fear mongering regarding safety has put the US 30 years behind the rest of the world in advances.  Our shutdown of reprocessing to stalemate proliferation has failed.  The rest of the world has continued development and use, relegating the US into a catch-up mode with a 30 year gap.

In 2005, the Advanced Fuel Cycle Initiative was published and initiated.  A read through reveals a consistent and advanced plan forward to energy independence and reduction of consumption of ancient fossil fuels.  As a nuclear scientist, I saw the AFCI and the follow on Global Nuclear Energy Partnership (GNEP) programs as the cornerstone of an energy policy gone begging for many years.  It included closed cycle fuel systems, the production of more fuel, and solutions to the final minimal nuclear ash from recycling.  A smaller or single permanent repository as exemplified by Yucca Mtn. could be finally considered; more are not needed.  The national energy treasure in the discharged fuel could finally be used.  But, like many things too good to be true, political pressures made it nearly still-born in the US.  Regardless, other nations are going forward, building fast spectrum breeder reactors, reprocessing fuel, and adopting the GNEP concept.

Several technology testing needs were identified in the AFCI, including new fuels, materials, reactor design, and disposal methods.   Many of these needs are stalled because the US has chosen not to use its own facilities and foreign reactors are allocated to parochial needs.  Some of those preserved and usable world class facilities are less than 20 miles from this hearing.

It is time to break out of this malaise of laggard action.  It should be the recommendation of this study group that the US re-emphasize and move forward on programs outlined in the AFCI and GNEP.  This plan has solutions for final nuclear waste, the majority of which is of minor amount in comparison to the huge advantage of modern nuclear energy.   It also provides utility in domestically supplying industrial and medical isotopes.

On every energy front, the only long term solutions outside of nuclear bring about higher costs, poor efficiency, non-reliability, and reduced availability, all major hits on the primary energy source criteria noted earlier, a de facto war on the poor.  If it does not play in this arena, the US will cease to be a world influencer.

Ocean CO2 Acidification Impact Questioned

The gauntlet was thrown on climate change when the sound bites of ‘the science is settled’ and ‘consensus of scientists’ were uttered. Long before that, this scientist was aghast at the pontificating that man can change the weather, at least to the extent of catastrophe. As a result of the bites and the astonishment, scientists have come to the front with continuing research to understand, and in the ensuing discoveries, rebut and rebuke the ‘consensus’.

The US Senate has had hearings regarding absorption of anthropogenic carbon dioxide emissions dissolving into the oceans and changing the acidity therein. Senator Maria Cantwell1 (Washington State) has stated that it’s obvious that shellfish are negatively impacted due to increasing CO2 from human activities. More on this later.

Absorption is not new, every carbonated beverage is an example enhanced by overpressure. Henry and Clausius–Clapeyron have well described gas absorption rules. Buffer solution chemistry further describes expectations on degree of acidity changes for weak acids such as carbonic, ie. limitations due to the normal ocean brew.

Figure 1 American lobster reared for 60 days at normal levels of CO2 (left) and under high levels of CO2 (2850 ppm). “There is no magic formula to predict how different species will respond, but one thing you can be sure of is that ecosystems as a whole will change because of these varied individual responses,” Justin Ries predicts.  http://futurity.org/earth-environment/jumbo-shellfish-rule-in-acidic-oceans/

On the heals of the ‘viewing with alarm’ and ‘we must do something now’ come several scientific papers which show contrary evidence to potential loss of crustacean life in the seas due to excess CO2 and temperature increase. Findley2, et al, report that barnacles are not really affected by increased CO2 other than perhaps to have improved calcification (better shells). Rodolfo-Metalp3, et al, report that temperate zone corals also improve their livelihood, noting a secondary effect that photosynthesis increases if the waters warm slightly providing more food for them.
And, Cohen and McCorkel4 have shown a dramatic increase in lobster (Figure 15) and crab growth rates with increased CO2 concentrations, noting that they had not detected much up or down in other species.

Are these definitive? Absolutely, when compared to the above sound bites and alarmist posturing. In reality, it most assuredly shows that there is much more work to be done in understanding this wonderful spaceship Earth on which we live. Before we start leaping as lemmings, we better figure out what is going on.

Another shot over the bow is a just published ‘cross examination’ by Johnston6 from the University of Pennsylvania Law School. With over two years of study, Mr. Johnston has examined the Intergovernmental Panel on Climate Change (IPCC) and its periodic Assessment Reports (AR) on climate change. His approach was to dissect and compare statements within and without the documents for consistency, clarity, and accuracy from a legal perspective. He notes serious problems with the debunked Hockey Stick, projections of climate sensitivity, modeling inconsistencies, ignorance of water vapor (cloud effects, humidity, snow, and ice) effects, and general ignoring or dismissing of valuable contrary studies and empirical evidence. On the one point of the missing cloud effects, he comments:

“…The results reported by Lindzen7 and Choi would seem to suggest that the fundamental assumption in climate models used by the IPCC – of large positive feedbacks – indeed the assumption that by itself is responsible for potentially catastrophic large temperature increases – is strongly disconfirmed by the existing evidence. …”

So, even an educated non-scientist can see through the story and understand the issues from basic principles and observations. He cites with numerous quotes, 343 literature references in coming to his conclusions: politically correct conventional wisdom on climate change as driven by IPCC and cohorts is simply wrong and without basis.

Shellfish production and CO2 increase

Shellfish production and CO2 increase

To finish, I said I would have more on Senator Cantwell’s opinion. Her statement caused me to investigate the status of shellfish in US economics. I found that from 1995 to 2008, the shellfish market in the US doubled going from 0.5 million to 1.0 million metric tonnes annually. During that same period, atmospheric CO2 increased 6.4%. Mathematically, there is a 95% correlation in the data (see figures). To their credit, the petitioners8 cite observational data on softening of oyster shells and clams in contrast to the literature cited herein. But, is it possible that overfishing to satisfy the palate is not allowing proper shell maturation? Facetiously,  is the increased consumption causing more CO2 or is it the other way round?

Obviously, the more we know, the more we need to know before we jump off into the abyss of cap and trade.

Taxing health care plan premiums

A current item on the internet is the ’sudden’ discovery in the new federal health care legislation that employer funds for health care premiums are going to be included in employee ‘total’ pay and thus subject to taxation or tax bracket creep.   Let’s do some thinking about this.

First, does anyone know of any employer who has not represented the company provided insurance as an overall employee salary/wage.  It is a part of the cost of an employee to the business.  That’s reality.  I have always recognized that and been grateful for what it was.  I also have many times calculated the average payout rate for a group of employees and found it to be nearly a factor of 10 more than what my contribution (on the pay stub) may have been.  Maybe if that money was given directly to me on the assumption I would have found my own individual insurance, I could have gotten it a bit cheaper, but unlikely.  That’s what grouping is all about, generally selected by the employer when it exists.

Second, shortly after World War II, business was granted tax incentives to provide health plans.  This was a time of high inflation, excess capacity, and excess returning military people.  The incentive spurred job creation.  Ie, reducing taxes actually stimulates more business and jobs.  It works.  Prime example is the Irish economy in the last decade of the 20th century.  Regardless, the business tax shelter continued until whatever is now about to happen.

Third, there are small businesses which have never provided health plans because they 1) were not big enough to have sufficient profit margin and mass generated funds to live and support a plan, and 2) have too small a group to gain any economic leverage in the insurance market.  Thus, there is no benefit margin to tax, and no hope for recognition of excess ‘hidden’ payments to the employee.  If the intent is successful, the ‘extra’ tax will be a wealth redistribution for health care to the poor or perhaps the small business employees.  This remains to be seen.

Yes, tax brackets will now change, except for special unionized groups to 2018.  But, suppose the ‘benefit’ amount, say, on the order of $26,000 per year is added to the employee pay and actually given out on the stipulation that it be used to buy personal insurance.  Now the individual has to take command and understand how that money is spent.  If they are in good health, they might be able to find catastrophic type coverage for $17,000 per year, leaving a net $9000 (which would be taxed) to play with.  The chronically ill or those with risky behavior (smoking, bungee jumping) pay up to the $26,000.  Now we have consumer driven health care (like buying a TV) and a population which examines their life choices with their own pocketbook.  If they choose to not have health care, tough, they pay as they go at standard published maximum risk rates.  My barber has elected the latter for 40 years very successfully, saving a portion of income with interest growth.  Would you properly use the allocation?  Would Joe Six-Bagle do so?

If the current health bill were tweaked to have the health benefit considered as a pre-tax deduction, then the cost incentive is removed from the business and shifted to the employee.  The unintended consequences are that without business tax avoidance incentive, the health allocation will go down, gradually moving us back to self reliance anyway.

Bottom line?  We have drifted health care through an ever increasing pay/cost/benefit economic maze to a behemoth that may be impossible to fix without a major upheaval in all sectors, and I really mean ALL.

Finally, it is my concern that the top level controllers are about the business of rationing health care.  Follow the thread at http://kandg.org/WPBlogger/?p=224

An Electric Car Conundrum

US energy independence is really anchored into the transportation sector.  Therefore, our huge domestically supplied electrical system can only help if that power somehow leaps into the fuel tank.  Electric cars with rechargeable batteries come quickly to mind.  But here is a twist:

” … Avoiding the ugly: Swapping coal for oil?
The biggest battle in the EPA’ s new rule was over how to treat electric cars. While the industry likes to use the term ‘zero emissions vehicle’, a plug-in car requires electricity from the grid. Several estimates I’ve seen put the amount of energy used in the range of 3 miles per kWH. If you’re connected to the hydroelectric-powered clean grid up in Washington, your plug-in would be six times less carbon intensive than a gas powered vehicle. But if you operate that same car in coal-dependent North Dakota, then your ‘zero emissions vehicle’ would actually be 20% more emissions intensive than if it used gasoline. Of course you can offset this electricity use by supporting wind farms in North Dakota, but the vehicle itself is far from ‘zero emissions’. …”

It’s a given despite agitation for cap and trade, climate change, ad nauseam, that coal plants will be around for a fair amount of time to come as touted alternatives are merely supplemental.  And the Waxman-Markey bill is only expected to help mitigate ‘warming’ by 0.05ºC, at best.  Therefore, what’s left?  Dare we say nuclear?

There are some other ideas kicking around for alternative (true substitute) transportation fuels.  But, these require thermodynamic chemistry reversals which require lots of energy.  Dare we say nuclear?

Cancer patient experiences lack of ‘dye’

After removal of a cancerous kidney, a patient is informed that the required ‘dye’ needed to confirm success and whole body assessment for next level of diagnosis and treatment is unavailable. Being an experienced nuclear scientist and physical chemist, the patient easily figures out that the ‘dye’ is SPECT radioactive isotope 99mTc. Read about his frustration at Citizens for Medical Isotopes of being denied something he advocated for others at all levels of public and government opportunities.

It is truly ironic that the media driven paranoia regarding things radioactive or nuclear has caused medical professionals to hide terms such as medical isotopes and nuclear magnetic resonance (non-radioactive) with soft words such as ‘dye’ and ‘MRI’ respectively.  The unintended consequences are that the public is now illiterate to what many of us have been saying for years.  The life supporting medical isotope supplies are fragile and are now catastrophically missing due to foreign nuclear reactor shutdowns.  The US has frittered away its expertise and infrastructure to the now being learned expense of patient health and foreign supply risk.  It’s here, it’s now, and there is no fast solution to rebuild what modern medicine needs.
