JU!i 7 1979 MEMORANDUM FOR:
File FROM:
Saul Levine, Director Office of Nuclear Regulatory Research
SUBJECT:
PRINCIPAL CONTACT MADE WITH EXTERNAL ORGANIZATIONS DURING TMI 2 ACCIDENT 1.
I spoke with Robert Ritzmann of Science Applications concerning H2 and 02 generation rates in TMI 2 vessel in the period March 31 - April 1.
He infonned me that, although an increase without considerations of a reformation rate of H2 and 02 due to bubble back pressure, that the 1 percent rate was probably too high.
He also said that he felt the rate was probably no higher than 0.1 percent per day and could be zero, but that he did not have the data to calculate an explicit rate.
2.
I spoke with James Proctor of the Naval Surface Weapons Center about the effects of a Hydrogen explosion on vessel integrity. He said the cylindrical position of the vessel would be subjected to about 6 percent strain, which should not break it, and that it would also be subjected to a lifting force of about 1.5 X 108 lbs. He could not calculate whether the main loop piping could hold the vessel down when subjected to this force, since he did not have detailed inforination on plant layout.
