SURTECT: General Informtion on Alumina Cenent

Dear Mr. Chappell:

'Ihank you for the timo you and your staff spent recently with the BR-100 l

transportation cask development team. We appreciate your interest arti I

ocrrents on the approach that Ribcock & Wilcox is taking to this important l

project.

j Please fird enclocod scrno informtion on the alumim coment you requested during our meeting. 'Iho cenent illustratcd is a calcium alumimte-bascd i

product, similar to that proposed on the DR-100.

It hardens rapidly to a l

ruch higher strergth than the roro conventiom1 Ibrtland Cerent. Tho a,gregato used with this ceent for the DR-100 is a patentcd ccrbirution of hydrated calcium torato (Ca2 6115H O) ard alumim po der. 'Ihese B0 2

aggttgates provido enhanced radiation shieldirg capabilitics ard heat l

abcorption capacity urder fire conditions, other desirable characteristics of the concreto include high tcrporaturo resistanco, a high level of bourd water, ard a low expansion coefficient urder frect.ing corditions.

f If you would like additicml informtion or have any questions with rugard to this cenent or any other aspect of our developnent work, please call rn (804-385-3609) or Di McGuinn (804-385-3446). We look forward to additiomi i

interactions with the lmC staff as the BR-100 cai project prcgresses.

Yours truly,
