Dear Hr. Denton:
In our letter AEP:NRC:0678H dated August 2, 1984 we antic1pated having the capability to Cake undiluted grab samples by September, 1984.
This commitment was made to satisfy the requirements of NUREG-0737, Item II.B.3 and Che subsequent elarifications to that item.
The undiluted liquid grab samples are required as backup to our 1n-line monitoring of pH and dissolved
At the present time, we are using the Interim Sampling station to sat1sfy that commitment.
This station had originally been installed to meet the requirements of NUREG-0578. It has been replaced with the PASS diluted sampling port except as noted above.
The Interim Sampling
- station, however, is inconvenient to operate.
Because of the relatively large sample that is obtained, the sampler is required to push a heavy lead shielded cask.
Th1s is undesirable from the viewpoint of occupational health and safety.
As discussed with your staff, we are planning to replace that system with a septum sampling port similar to our PASS diluted 'sampling port.
The new system utilizes a syr inge to obtain the sample.
Because the sample obtained is very small, it is easily transported using small portable shield1ng containers.
The 1nstallation will require loss of undiluted liquid grab sampling capability in both units for a period of two to five weeks.
He feel Che temporary loss of undiluted liquid sampling capability is acceptable because the probability of a major loss-of<<coolant accident occurring during the installation period is exceedingly small.
Additionally, the PASS-diluted sampling port will continue to be available while the modificat1ons are being performed.
Should you have any concerns regard1ng the above, we would appreciate notification by Hay 15, 1985.
