A 10CTR'50, Appendix-3, Criterion'V, states, in part: " Activities affec-ing quali:y shall be prescribed by docu=ented instrue:1ons, procedures, or drawings, of a type appropriate to.:he cir'u=s:ances

.... Instructions, procedures, or drawings shall include appre;;ia:e

Contrary to the above, the 3echtel Quality Assurance Manual - ASMI See:icn-l III, Division 1, Docu=en: No. WD-1,' paragraph 7.4, provides for sa=pling inspec:Lons (surveillance) without-specifying a sa=p11:3 plan. There are l .

This ite= applies to Uni: No. 1 and Uni: No. 2.

This.is a Severity Level V Viola:1eu (S uphle=en t II).

Reseense to Violation:

-The.use of surveillance inspections is a key ele =en: o'f an effectiva inspection progra= and is a co==on practice in the nuclear c==strue: ion

In addi: ion, since surveillances are employed on ASME Section !!! ac:ivi:ies,

• ~ surveillances are defined in the ASMI appreved (3ech:el) ii=erick quali:y Assurance Manual as:

"To progressively =cnico by rande=1y witnessing and inspec:in- 1:e=s and work operations before, during and af:e in-process cons: uc:icn.
