Attachment A Page 1 of 3 Docket Nos. 50-277 50-278 I.
Restatement of Violation As a result of the inspection conducted on June 16-19, 1987, and in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement Policy) (1986), the following violation was identified:
A.
10 CFR 50, Appendix B, Criterion V requires that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings and that they shall include appropriate quantitative or qualitt.tive acceptance criteria for determining that important activities have been satisfactorily accomplished.
The licensee's Quality Assurance Program incorporated 10 CFR 50, Appendix B prior to issuance of Bulletin 80-11, Masonry Wall Design.
Contrary to the above, as of June 19, 1987, a written procedure providing the scope and the quantitative or qualitative acceptance criteria was not documented for the 1980 walkdown survey of block walls performed in response to NRC Bulletin 80-11.
This lack of procedural documentation prevented confirmation that all walls whose failure could affect safety related equipment were listed.
This is a Severity Level V violation (Supplement 1).
Response to Violation Admission or Denial of Alleged Violation:
Philadelphia Electric Company (PECo) acknowledges that the violation did occur as stated in the Notice of Violation.
Corrective Action Taken and Results Achieved:
PECo Mechanical Engineering Division is developing a procedure which will provide the scope and criteria for the identification, survey and classification of all masonry walls.
This procedure J

Attachment A Page 3 of 3 Docket Nos. 50-277 50-278 omission of the specified anchor bolts coupled with an apparent through crack would invalidate the reevaluation calculations and raises questions regarding the licensee's conclusion that the walls are structurally adequate.
The licensee was requested to provide additional information describing their resolutions and a proposed schedule for actions.
This item is unresolved pending licensee's submittal and NRC review of the additional information described above (50-277/87-16-02 and 50-278/87-16-02).
Response to Unresolved Item:
PECo believes that the anchor bolts do exist, as detailed in the design drawings.
In order to resolve this item, PECO will chip out the mortar joint at three of the walls inspected by the NRC and confirm that the anchors exist.
This work is scheduled to begin October 1, 1987 and be completed by November 1, 1987.
