MEMORANDUM FOR:
G.
S. Spencer, Chief, Reactor Construction and Engineering Support Branch FROM:
SUBJECT'egional Evaluation Review Board - Palo Verde SEMI-ANNUAL REGIONAL EVALUATION OF PALO VERDE UNITS 1, 2 AND 3 Previous enforcement actions and results (including escalated enforcement actions).
b.
Licensee's responsiveness and ability to execute corrective actions identified by the NRC and licensee management systems.
c.
Licensee actions in the area of IE Bulletins, licensee event (Part 21 and 50.55(e)) reports.
It is the opinion of the Board, based on the results of the review, that the licensee's performance is generally satisfactory and that strong effort by the licensee should continue to ensure that current and future work is adequately controlled.
In addition, it is the opinion of the Board that NRC:RV inspection efforts should be increased in the areas of containment dome liner installation, piping hangers and supports, and component storage and maintenance.
Rationale for these actions is provided in the enclosed Palo Verde Evaluation Form.
The Regional Evaluation Review Board for Palo Verde met on May 30,
- 1980, to perform the evaluation of project activities for the period of May 1979 I
through May 1980.
The board reviewed the following areas:

MC 2955 5/ll/79 Meeting held in Region Y office concerning Unit 1
dome liner plate.
F.
Justification of Evaluations of Functional Areas Cate orized as Re uirin an Increase sn Ins ection Fre uenc /Sco e
See eva uatson sheet Containment Dome Liner Installation - Units 2
8 3
On Unit 1, severe misfit of dome segments led to Region Y concern, and development of additional procedures and construction tolerances to prevent building in high residual stresses in the liner plate.
Pi in Han ers and Su orts To date there have been occasions where weld sizes have not been in compliance with requirements.
In addition, 50.55(e) reports have identified problems with support design and welding.
This is not just a Palo Yerde problem, but appears to be industry wide and needs additional inspection effort.
Com onent Stora e After llarehouse Release Problems have been encountered with leaving pipe openings uncovered, installed equipment improperly covered, pipe spools and weld electrodic carelessly handled/controlled.
