4 Welding conditions, practices, and qualification deficiencies have resulted 13 in unsafe weld conditions and lack of assurance about inaccessible welds, as seen in.

class 1 and 2 piping (SER p 5-14)
- b. Iow alloy steel welding (SER 5 -1 0, 5 -11) c.. corrosion damage to piping due to electro-chemical attack because of improper grounding during welding,(FES p 9-39, No. 7, Midland Daily News, 7-20-82) 5.
Despite extensive deficiencies and reliability questions associated with the DGB
/6 onsite power supply due to soil settlemeht problems, the offsite/onsite blackout power failure accident is not a postulated design basis event for safe shutdown and tlkis represents a serious unconsidered threat to public health and safety,
(The AFW system--see contention 15--and a turbine driven pump are not designed for and cannoIbe relied upon to provide sufficient cooling water from the non-category I condensate tanks to perform this essential safety function.
(SER p C-16,17) k l
6> The NRC risli assessment concerning potential release of radioabtivity to T
g underlying groundwater (DES p 5-58) is unconservative because it depends too b
heavily on the natural safeguard of the " essentially impervious" clay layer, "Q e 6 whose properties have not been clearly establisheJ to provide the assumed' barrier (Kane OM-QL testimony p 4292), and it does not consider potential effects of permanent dewatering on the ground-water relationships. Therefore, h
g public health and safety is jeopardized by these inadequacies.
40 7. Reactor containment integrity.is compromised by the combined effects of:
N
- a. RVP Support Modification (79-10) 6
- b. lack of adequate shear reinforcement (81-05') which is uncorrectable i'
- c. inadequate loading combinations (SER p 3-21) d.
failure to postulate containment pipe break effects (SER 3.6.2)
N
- e. NSSS Seismic /LOCA deficiencies (80-07) and the interrelated effect of these unresolved safety issues is not addressed by the NRC in the SER.

- s. The ACRS has recommended an assessment of Midland's design adequacy
^
and construction quality in their 6/18/82 report (SER Supplement 1, Appendix G)
~
In order to assure that this audit be thorough and objective, it must be per
- formed by an indepanden. third party ob compe ing contracting firm., Such r-a requirement was imposed by the ASLB in the Houston Power and Light, 50-498 and 50-499 OL proceeding, 4/30/82 And, due to the pattern of design deficiencies (4/20/52 SALP,'p 163 such an independent audit is n'ecessary to assure the design' integrity of this plant. However, the NRC has not required (SER Supplement 1, p 19-2(1)). and CPC has not committed (7/9/82 Tedesco to Cook letter) to ruch an independent audit.
