Docket no. 50-320 Constructicn Fer=it CFFR-66 Inspecticn No. 50-320/74-06 Recnence to Descrintion of Apnarent Violations Apne_ rent Violaticn "Criterica V of Appendix 3 cf 10CFR50 requires that activities affecting quality be acecrplished in accordance with docu=ented instructions, procedures,
or drawings.
Contrary to the above, it was observed that unused lov hydrogen velding electrodes were left in an cpen container exposed to the atmosphere for an extended pericd. This was in violation of site directive MCP-2-2 which requires that unused lov hydrogen filler =aterial in opened containers be returned to
~
the issuing crib within four hours."
Corrr'tive Actiens An investigation was begun upon discovery cf the above referenced situation, and the investigation disclosed that a.
the situation occurred 62. spite adequate procedural controls, b.
the velder who was responsible for the electrodes si= ply failed to report when they became missing, and c.
the use of these electrodes did 'not affect quality, in that the electrodes vere used only to mount a te=porary holding bracket, the function of which was to hold another co=ponent in position while the co=penent was being erected.
For this situation, i==ediate corrective acticns censisted -of destroying the subject electrodes, thus ensurin6 that they would a.
not be used in future applications, and b.
=aking a deter =ination, that there vere no previous applications.
