[ RadSafe ] Permissible volume of coffee Calculation by Mr.John Dunster

[parthasarathy k s]

Friends,

When Mr John Dunster from the UK was the News Editor of  The Health Physics Journal, he calculated the volume of coffee that may be drunk daily without harm. I recall that he made some very conservative assumptions to get at the number. Can any one who has access to old Volumes of Health Physics locate that page and send me a scanned copy? I believe that he was news editor of the journal during late 60s.


regards
Parthasarathy

Dear Dr Stanford,

Who will spend money for the developmental efforts? Uranium is cheaply available. LWR is not certainly the best; but it is readily available. Funding for R & D on newer technologies will have to come from the Government. I recall your comments that IFR technology is more completely developed compared to the breeders.

My friends who are deeply involved in Fast Breeder Reactor development (500 MWe capacity) tell me that they will be able to sell electricity at a cost comparable to that from Indian PHWRS. In India, price of power is by law administered  by the Central Government. In the case of nuclear power the Atomic Energy Act 1962 gives Central Government an enabling provision to decide power tariff. So talking about the cost of power in India is only an academic exercise! 

Will there ever be a breakthrough in technology which may lead to power too cheap to meter? It happened in communication technology. In the 70s those who do not have a telephone in India will have to book a call at a telephone exchange to talk to another subscriber a few hundred miles away and wait for his turn. Now there is an explosive growth in mobile phone technology. Fifty years ago we did not think that we would be able to carry a telephone exchange in our pocket.Telephone service between India and USA has almost become too cheap to meter!

Can we expect similar developments in energy production?

Regards
Parthasarathy

     Actually, guys, we could indeed "mine" the DU that we've already accumulated, as Peter suggests, and we probably will (but it will take a while to get going).  Using the plutonium from used LWR fuel as the essential catalyst to get started, fast reactors such as the IFR and its ilk (PRISM, TWR, 4S, etc) can power the world for centuries on the uranium that's already been mined -- and with no more uranium enrichment needed, ever.

The continued mining of uranium is a symptom of the profound sickness of our government and the corporations it serves, well demonstrated by our preference for death over life. All mining should be stopped worldwide. We can mine the huge deposits of DU on the premises of every nuclear plant.
By continuing to mine, we are saying that money is more important than life, that we don't care about  God's Creation, that our own lives are expendable in the pursuit of money. We prostrate ourselves before the Golden Calf!

We must DO something! --Peter G Cohen
