April 7, 1979 John Callins L I QUI D RA?VASTE 1.
Although plans are being made for the long run, there doesn't seem to be a management program for the immediate future.
At least there are two items that need at tent ion-or we will need canoes.
2.
The present plans are being based on2000 gallons / day-coming f rom pump seals leakage.
Based on tank levels, during the 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> I was away, over 5000 gallons was added.
Some cau.e from sample decontamination.
There are other sources that we do not kno.< yet.
Ve should be morc realistic in our estimate and see where and hav we are going to hmndle it.
3 Ve shoutc 3k into the primary coolant location to 3 L000 gpm,
~
and the amount of letdoun it will generate. The best solution I see is to install some of the available tank (s) in the scent fuel pool.
Putting the water directly in the pool is not good because of the iodine.
Holding in other tanks might still create oroblers, if the tanks are in the pool, we have rany advantages-charcoal filter in the ventilation system; except for the top, good shielding; easy access.
Actually, we can put a small charcoal filter on the vent of the tank-since the filter will be only for breathing of the tank.
In addition, the spent fuel pool is Seismic Class I, and in case of tank f'ilure, the contents are held up.
L.
The ra 'n probiec we have in handling p,st-accident liquid radsaste is iodine.
Ve should look into using a zeolite / charcoal / sand filter.
5.
Ve sho;1d look into using nore ef fectively the radwaste e/ararator and boric acid evaporator.
Apparently, there are no polishing demin:ralizers for the overhead.
Installing demineralizers should help, ar.d t he r e f ore, we shoul d install them ASAP.

e e.,
John Collins April 7, 1979 6.
We have seseral liquid radsaste tanks originally purchased for Unit 1.
We should install them with curbs-so that in case one breaks, there will not be a spreading of c;ntamination.
The s e tanks could be used to handle treated ef fluents before final disposal (sol idi fy or dump).
7.
We discussed this with Snyder from Oak Ridge, White from Burns and Roe, 2 NUS consultants, etc.
Snyder developed the attached f l ess hee t.
We all agreed that installation of tankage in the spent fuel pool should be approved post-haste.
8.
Apparently the level indication on many radwaste tanks are not reliable.
From what I understand, we really don't know how nuch free space is available in the tanks-or, we won' t knew when the tanks are full and overflow.
