4 WVES.TPL.70 7 WNS LONG TERM TESTING OF CEMENT '.lASTE FORM Rev. I 1.0 PURPOSE The purpose of the long term phase of the testing program is to demonstrate long term retention of concrete compressive strength and minimal degradation due to cracking and spalling caused by aging.

2.0 APPLICABILITY This Plan applies to periodic confirmatory testing of VVHS cemented low level waste generated under sceual production conditions to demonscrate long term vaste form stability.

3.0 SCOPE This testing is intended to demonverate and verify waste form stability '

by coring selected production drums, performing compressive strength testing and documentins detailed visual inspections.

4.0 DESCRIPTION

Twenty (20) drums shall be selected and set aside from a given produ: tion run for future evaluation as described, This isolation will facilitate handling by minimizin5 stacking, unstacking and restacking.

> After an initial cure period of six (6) months, cores shall be obtained from thu first isolated production drum as follows: Two (2) from upper section, two (2) from center section, and two (2) from the lower section of the drum. Core segments shell have a minimum length over diameter of 2:1 to facilitate test sample preparation.

As test specimens are generated, they shall be bagged and uniquely identified to include date, drum number, and core location, i.e., (A top, B middle, C bottom).

Each core shall be visually examined for indications of cracking or spa 1'.*ng and then photographed.

Upon completion of visual examination, one core specimen from each level shall be destructively evaluated for compressive strength per ASTM C-39.

t n . . .

WNS.TPL.70 7 Rov. 1 The restining three core specimens shall remain bsgged and stored in the RTS Drum Cell environment for visual examination at six (6) month interv,ts Tor signs of cracking or spalling.

For i.ine (9) drums the above steps shall be repeated in their entirety with t six month lag time between the start of each. This test vill cove.r a five (5) year period. The remaining ten (10) drums vill be stored in the RTS Drua Cell for possible future test (s).

> Af ter the drum is cored it will be placed into an overpack box and placed back into storage.
