JUN 14.M9 Docket :10. STil 50-437 Offshore Power Systems ATTil: !:r. A. Collier President P. 0. Box 8000 8000 Arlington Expressway Jacksonville, Florida 32211 Gentlemen:
As discussed during our nm ing of June 8,1979, the :lRC staff finds that a further assessment should be made of the potential impacts that may result from the release of insoluble core debris particles into the open ocean environment following a postulated core-melt acciht at a floating nuclear power plant.
So as to assist the staff in its evaluation we request that you provide an analysis which considers, but should not be restricted to the following factors:
1.0 An estimate of the quantity and size distribution of particles transported out of the breakwater into the ocean.
The calculations should also include consideraticn of mechanisms leading to generation and transport of particles within the breakwater.
These include:
1.1 Steam explosions 1.2 Circulation due to waves and turbulence 1.3 Circulation due to thermal convection from hot core debris 1.4 Circulation due to the operatien of the cooling system for an adjacent Flip unit.
1.5 Ocean current flow through breakwater openings 1.6 Tidal flushing 1.7 Flotation of particles by dissolved gases in seawater.
>l
I Offshore Power Systems.,
2.0 For the size distribution of particles identified, determine the dispersion and transport of particles outside of the breakwater.
This analysis should include consideration of the short-term initial transport nechanisms as well as the long-tcrm far field dispersion and transport of the particles.
3.0 Assess the radiological effects of the particles on ocean biota as well as to man through the food chain pathway.
Provide estimates of affected area for damage to biota.
4.0 Discuss methods for interdiction and mitigation of the radiactive particles.
The consideration of the above mentioned factors should describe any differences in calculations and results from those previously presented in the FES, Part III and the Liquid Pathway Generic Study Report with respect to both insoluble and dissolved radioactive core-debris.
We request that you provide the NRC a with written response including general calculations used to assess these matters by July 13, 1979.
Sincerely 7
