&Enforcement U.S.NuclearRegulatory Commission Washington, D.C.20555Mr.G.McDonald, DirectorOfficeofManagement Information
Cause Three conditions may have contributed to the installation error.They are: 1.Pro)ect engineering did not specify the required slope (i e.l/2" per foot min)on some of the design drawings.2.Construction failed to incorporate specified slope requirements on some of the field prepared fabrication isometric drawings.3.Construction failed in some cases to install the small pipe to the slope specified on the Field fabrication isometric drawings.Anal sis of Safet Implications Project Engineering has determined if the deficiency were to have gone uncorrected it could have adversely affected the safe operation of the plant, and it is therefore deemed reportable under 10CFR 50.55(e).This deficiency could produce an error in essential instrumentation in excess of design limits.Inaccurate instrument readings and delayed trips could result.on lines which have differential instruments which function on low differential pressures.
