'. 4 No. NRC SER Suggestion WVNS' Response 3 Significant pitting was observed cont on the coupons in the zeolite region. However, the depth of the pitting could not be accurately measured.
A pitting corrosion inhibitor has bean subsequently added to the tank. Action will be taken to quantify pitting depths during future coupon .
examination. l Stress corrosion cracking and cravice corrosion were not detected by coupon examination.
Stress corrosion cracking in tank 8D-1 is assessed by examination of U-bend corrosion coupons in the various regions of the tank. U-bend coupons are designed and fabricated to ASTM-G30 requirements.
Pitting corrosion is being measured by corrosion coupons in tank 8D-1. The only significant pitting corrosion is present in the zeolite region of the tank.
Examination of coupons submerged in the teolite at the bottom of the tank indicate that a localized pitting corrosion of up to a maximum of 4.06 mils /yr may have been present prior to addition of the pitting corrosion inhibitor (sodium nitrate) to the tank. The rate of pitting will be assesead in mid-1992 when the. coupons will be removed again for examination.
Corrosion data from tank 8D-2 have been unavailable since the NFS coupons were removed from the tank in 1982. These coupons indicated a general corrosion I rate of.0.53 mils /yr for the liquid region.

No. NRC SER Suogestion WVNS' Response 3 In October 1991, a series of cent corrosion probes were installed into tank 8D-2 to measure actual corrosion rates. These probes are advantageous in that the time required for frequent corrosion coupon removal, cleaning, examination-and reinstallation is greatly reduced. The probes provide on-line indication of general tank corrosion in all three regions:
sludge, liquid and vapor.
During the limited period of time these probes have been operating, general corrosion rate indications have been:
3.2 mils /yr in the sludge region 0.3 mils /yr in the liquid region 1.9 mils /yr in the vapor-region n addition, 0.2 mils /yr pitting corrosion in the liquid region is indicated by the pitting corrosion probe. -The WVDP is currently assessing the need and feasibility of installing corrosion coupons into tank SD-2, in addition to the existing corrosion probes.
Stress corrosion cracking in tank 8D-2 is not currently measured, but laboratory corrosion tests at Battelle-PNL are underway to determine if this type of corrosion is significant.

Initial data from this probe indicates a pitting corrosion rate of 0.2 mils /yr, although tne measurement probe and signal conditioning syntam are still in the developmental stage.
Preparations are being made for laboratory tests at Battelle-PNL to evaluate the magnitude of corrosion on the tank exteriors due to the infiltration of surface and ground water. This data will be combined with internal corrosion data to predict total tank wall corre* on.
