APR 19125, MEMORANDUM FOR: James Meyer, OCM FROM:
T. A. Rehm Assistant for Operations, EDO
SUBJECT:
ADDITIONAL INF)RMATION ON STEAM EXPLOSIONS Knowing of your interest in steam explosion research, I am forwarding to you some additional information generated in part by my staff, and in part by others. The enclosures are:
1.
Memorandum from Mr. Dircks to the Consnissioners, 3/7/85, transmitting the report of the Steam Explosion Review Group (SERG).
2.
Memorandum by C. N. Kelber to Distribution, 3/14/85, transmitting additional information on steam explosions. This memorandum suggests the SERG report may not have included consideration of all relevant factors.
3.
Memorandum by J. Hopenfeld to 0. E. Bassett, 01/15/85, Steam Explosions, relating his concerns over the report of SERG, and describing technical conclusions drawn from liquid-liquid explosions occurring between liquified natural gas (LNG) and water.
4.
Chapter 10 of AEEW-R 1842, " Report on Phase 1 of the PWR Severe Accident Containment Study"; the report is labeled Not for Publication.
This chapter gives the UKAEA's views of steam explosions, i
5.
A copy of a paper on the role of steam explosions in volcanic action, one of a series of papers on this topic written by staff at Los Alamos.
The emphasis in enclosures 2 and 4 is on the role of confinement of the reactants in increasing the yield of the steam explosion. The emphasis in enclosure 3 is on the time scale for mixing, and the blast wave effects observed in LNG-water explosions. The emphasis in enciogure 5 is on the applicability of steam explosion data to explaining volC46fc eruptions on massive scales, such as the famous explosion at Krakatner i

reactor safety in 3 years or-less; if the budget is adequate, that plan will be carried out.
