Subject:
Byron Station Units 1 and 2 Braidwood Station Units 1 and 2 Po st-Accident Sampling, NRC Docke t No s. 50-45 8f, 50-456, 50-456, and 50-457 Dea r Mr. Den ton :
This is to provide advance FSAR information regardlng the Byron /Braidwood post accident sampling system.
NRC review of this information should make it unnecessary to impose License Condition 11 contemplated in the Byron SER.
Enclosed with this letter are additions to items 1 and 9 o f the response to FSAR question 281.7.
Analytical methods to be used under accident conditions are specified and personnel training is discussed.
This information will be incorporated into the Byron /
Braidwood FSAR at the earliest opportunity.
Please address further questions regarding this matter to this office.
One signed original and fif teen copies o f this letter are provided for your review.
Ve ry truly yours, f htfht "

Y ENCLOSURE Additional information for B/B FSAR Question 281.7, Items 1 and 9 Item 1:
" Demonstrate compliance with all requirements o f
.NUREG-0737, I I. B. 3, for sampling, chemical and radionuclide analysis capability, under accident conditions."
Byron Station High Radiation Sampling System Analyses Capabilities include the following items.
Analyses In s trumenta tion / Ty pe Location Chloride Ion Chromatograph (In-line)
Primary Sample Room.
Dissolved Hydrogen Gas Chromatograph (In-Line)
. Primary Sample Room Dissolved Oxygen Probe (In-line)
Primary Sample Room pH Probe (In-line)
Primary Sample Room Conductivity Probe (In-line)
Primary Sample Room Baron Ti tration (Grab Sample)
High Level Laboratory Item 9:
" Provide information on (a) testing frequency and type of testing to ensure long term operability of the post accident sampling system and (b) operator training requirements for post accident sampling."
The Byron Station Pos t-Accident Sampling System is the same system that will be used for routine sampling during normal operations of the plant by the Radiation Chemistry Department.
Based or this, minimal periodic training and testing will be required to maintain personnel competence and operability of the system.
The following testing and training frequencies will be maintained.
A.
Testing frequency of the Pos t-Accident Sampling System will be at a minimum of yearly.
All analysis functions for chloride, dissolved hydrogen, dissolved oxygen, pH, conductivity and boron will be verified.
B.
Formal initial training will be given to all personnel responsible for operation of the Pos t-Accident Sampling System.
Retraining will be given as necessary to maintain competence (minimum yearly).
