AFFIDAVIT OF KENNETH D.
BRIENZO-I, Kenneth D.
Brienzo, being duly sworn, depose and state:
1.
I am a Senior Engineer in the Project Engineering Department of Commonwealth Edison Company.
In that position I am responsible for review and approval of preoperational and startup test procedures and test results for both the Byron and Braidwood Stations.
2.
From 1982 to 1984 I was Accident and Transient Analysis Administrator for Consumers Power Company.
In that capacity I managed the activities of the Accident and Transient Analysis group in support of the operation of the Palisades and Big Rock Point nuclear plants.
These activities included per-forming accident and transient analysis for reload cores at each plant and for addressing safety questions during the operating cycle.
From 1978 to 1982, as a member of the Accident and Transient Analysis group at Consumers Power Company, I managed the Big Rock Point Probabilistic Risk Assessment and 8608220083 860918 3G
{DR ADOCK 05000456 PDR
4:
wrote a transient analysis methods report for the Big Rock
' Point plant for submittal to NRC reviewers.
From 1975 to 1978 I was a member of the Technical Staff at Consumers Power Company's Palisades Nuclear Plant.
In that capacityLI was responsible for reactor physics testing during the startup of the reactor following fuel reload.
3.
I received a B.S. degree in Physics from th'e University of Illinois in 1974 and an M.S. degree in Nuclear Engineering from the same institution in 1975.
I am a Licensed Professional Engineer in Illinois and Michigan.
4.
The purpose of my affidavit is to set forth the special measures that will be taken to guarantee that a boron concentration of 2000 parts per million (ppm) or greater will be maintained in the reactor coolant system, without relying on electrical systems or circuitry, throughout the fuel loading and precritical testing activities for which Commonwealth Edison is requestiong authorization.
5.
Commonwealth Edison's fuel loading and pre-critical testing activities will be carried out in accordance with the plant Technical Specifications, and systems and equipment as required by the Technical Specifications will be operational.
However, to establish the lack of any relationship between the limited authorization being sought and Intervenors' harassment contention involving L.K. Comstock, QC inspectors, Commonwealth Edison has demonstrated that it i-a
need not rely _on plant electrical systems and circuitry to-preclude criticality and thus assure the-public health and safety during the fuel loading and precritical testing activities.
6.
Mr. Slember's affidavit demonstrates that maintaining a boron concentration of 2000 ppm precludes criticality.
At all times during the core load and pre-critical test sequence, the boron concentration of the-reactor coolant and makeup water systems will be maintained' at no less than 2000 ppm.
Grab samples will be manually taken from the reactor coolant and makeup water systems and analyzed at least once per shift to verify that the boron concentration is at least 2000 ppm.
In addition, the makeup water system will be sampled and analyzed in this manner each time any water is added to the system to verify this concentration.
To preclude inadvertent boron dilution which could reduce the concentration below 2000 ppm, nonborated water sources will be isolated from the reactor coolant system by mechanically locking closed the appropriate valves with chains and padlocks.
l 7.
The above administrative controls ensure that i
no unborated water will be available as a makeup source to the. reactor coolant system.
Thus, no credit for any plant electrical system or circuitry is needed to ensure that the water in the reactor vessel is maintained at a boron l
l
concentration of 2000 ppm throughout the fuel loading and precritical testing activities for which Commonwealth Edison-is seeking authorization.
Further affiant sayeth not.
