Dear-Mr. Keppler:
INTERIM 10 CFR PART 50.55 (e) REPORT NO. U-59 INCONSISTENT INSTRUMENTATION INSTALLATION AND INSPECTION On July 27, 1983 Union Electric Company advised Mr.
Julian Hinds of the NRC of a potential significant deficiency reportable under 10 CFR 50.55(e).
The potential deficiency
' concerns the fact that our constructor's program for the in-stallation and inspection of instrumentation may not have been consistently applied to safety-related control valve access-ories and vendor supplied safety-related HVAC instrumentation.
As a result, work control and inspection documents were not generated for these items.
Thirteen airsets and one trans-ducer associated with certain safety-related control valves are affected.
In addition, the following safety-related HVAC instrumentation may be affected:
a)
Pressure differential indicator switches b)
Pressure differential transmitters c)
Radiation elements d)
Thermowells The full extent and effect of this potential defi-ciency have not yet been determined.
An analysis of the af-fected safety-related control valve accessories has determined that these items do not constitute a significant deficiency as a significant repair is not required to meet the criteria and basis defined in the PSAR.
Analysis of the affected
' safety-related HVAC. instruments has not been concluded at
-this time.
[ '

are controlled and inspected.
As an' additional control, no safety-related HVAC instruments or safety-related control valve t
