POSSIBLE RUNIT CLEANUP
400646

L

Backecround.

During previous conferences and decision-making processes, Runit

was placed lowon the priority list for soil cleanup, but was never completely
dropped as a potential cleanup candidate. Duricg the preparation for cleanup of

other islands, considerable time was required for DOE to characterize the necessary areas and volumes for soil cleanup. Because of this required lead time, itis

necessary to understand when Runit could be characterized and "imped" in order to

fit potential cleanup of Runit into the overall cleamip schedule.

IL Discussion. Although Runit is low on the priority list for cleanup, Enjebi is
now almost completed, Boken will not take long to complete, and the only remaining
soil cleanup on the northern islands (other than Runit) is the Aomon crypt.
Dependent upon the amountof soil that has to be excised from the Aomon crypt, up
to 5,000 cubic yards capacity may remain available in the Runit crater operation.
The amount of capacity left in the crater will be known within 3-4 months -- when
we do knowthis capacity, we need to have the Runit characterization well in hand so
that we will know where on Runit it will make sense to do any cleanup. There were
several ideas on this area:
a. Initiate soil cleanup starting in the southern portion of Runit and working
north (southern Runit is very low in suburanic contamination -- thus transuranic
cleanup of any areas in this southern portion would make this acreage available
should the People decide to use it in the future).
b, An alternative to doing southernRunit is to clean the highest level "hot
spots” throughout the northern portion
c.

The Director, DNA, pointed out that it is not necessary to decide which of

these alternatives to do now, but we do need to factor the "imping” of Runit into our
overall schedule. Another factor that would have to be determined would be the

criteria to which we would clean (i.e. , 40-80-160 pCi/gm).

Actions Required.

a

DOE to provide DNA with a schedule of “imping™ requirements for the next

few months in the northern islands together with a proposal for integrating

“imping™ and other characterizations of Runit into this schedule, to include when

and where.

b,

(FCZ prepare message to DOE-NVO formalizing this requirement.)

CJTG and FCDNAinitiate preliminary planning and examination of Runit

cleanup alternatives using various cleanup criteria. Detailed planning will necessarily await DOE characterization. (FCR/FCZ action. )
