Subject:
ICE-CONDENSER PRESSURE-SUPPRESSION CONCEPT
Dear Dr. Seaborg:
At its ninety-first aseting, on Novenier 2 and 3,1967, the Advisory Coaunittee on Reactor Safeguards reviewed a concept of an ice-condenser pressure-suppression scheme for a large pressurized-water reactor facility. A Subcomunittee met on October 27, 1967, in Washington, D.C.,
During its review, the Committee had the ben-to review this concept.
efit of discussions with representatives of the Westinghouse Electric Corporation and their consultants, and the AEC Regulatory Staff and l
of the documents listed below.
l The ice condenser provides for rapid absorption of thermal energy, released in the unlikely event of a loss-of-coolant accident, by condensing the released steam in a heat sink that consists of ice located in an annular refrigerated compartment. An operating deck The lower separates the containment into upper and lower chambers.The ice con-chamber houses the reactor and primary cooling system.in a loss-of-coolant acci-i denser connects the two chambers so that, the steam and air from the lower chamber flow to the condenser,
- dent, significantly reducing the peak and average pressures.
l The Westinghouse Electric Corporation has erected a test facility representing a full-scale 1/180-segment of the ice condenser for a Representatives of Westinghouse reported results large power reactor.
from this f acf.lity and from previous small-scale exploratory tests.
Westinghouse plans further tests and analyses.

Honorable Glenn T. Seeberg November 9, 1967 As with any new system, the design features of the ice condenser should be thoroughly explored and the appropriate margins evaluated by an applicant prior to submission in connection with a license application. The submittal should be fully documented to provide an adequate justification of the suitability of the system for the proposed facility.
The Committee believes that, subject to confirmation by additional tests and analytical studies, the ice-condenser concept can be success-fully engineered to provide a satisfactory pressure-suppression system.

Sincerely yours,
/s/ N. J. Palladino N. J. Palladino Chairman
