DESCRIPTION OF VIOLATIONS Metropolitan Edison Company Docket Nos. 50-289/320 License Nos. CPPR-40/66 I
Certain activities under your license appear to be in violation of Regulatory requirements as indicated below:
l 1.
Part 50.55e, 10 CFR 50, states in part:
.the holder of the permit shall notify the Commission of each deficiency found in design and construction which, were it to have remained uncorrected, could i
j have affected adversely the safety of operations of the nuclear power plant at any time throughout "the
]
expected lifetime of the plant.
Contrary to this requirement, three engineered safeguards pump motors were found to have been
().
water-damaged during the time of the flood which occurred on or about June 23, 1972 and were subse-quently removed for repair.
There was no equipment damage reported to Regulatory Operations in response i
to our letter of June 27, 1972 which addresses damage j
to equipment during the flood.
2.
10 CFR 50, Appendix B, Criterion V, states in part:
" Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings.
Instructions, procedures or drawings shall include appropriate quantitative or qualitative acceptance criteria.
" and Criterien XVI states in part:
" Measures shall be established to assure that conditions adversa to quality, such as failures, malfunctions, deficiencies, deviations and nonconformances are procptly identified anc corrected Contrary to the above:

Several' instances were identified under the engineered a.
safeguards consoles (CC and CR) where the physical separation of redundant channels was less than two inches which is less than the separation described in United Engineers and Constructors Procedure ECP-3, and the commitment documented in paragraph 8.2.2.12c of the FSAR. No deficiency reports had been prepared as required by United Engineers and Constructors Procedure i
QC-17.
i b.
Procedures have been prepared for use in verification that instrumentation, sensors, and associated lines have been installed in accordance with engineering drawings. However, the procedures do not include i
quantitative or qualitative acceptance criteria for the physical separation of instru=ents, sensors and their associated lines for redundant channels, to pre-i,'
clude a single failure within the protection system, f
.as described in paragraph 4.2 of IEEE 279, as required i
by paragraph 7.1.1 of the FSAR.
c.
The United Engineers and Constructors Procedure QC-13, t
which was revised on October 27, 1972, to reinstate the klh requirement for quarterly field audits of tools, gauges, and instruments, did not list the equipment subjected
/
to the audit nor provide quantitative or qualitative acce'ptance criteria.
Further, the-procedure permitted the person conducting the audit the discretion of deter-i 1
mining the applicability of the check list. As a conse-4 quence, the audit results did not supply adequate data to determine whether the intent of the procedure had been satisfactorily accomplished.
d.
United Engineers and Constructors Procedure ECP-10 requires that surveillance be performed on instru=ent
. panels, control boards, and related equiptent to assure that controlled storage conditions are maintained.
Metropolitan Edison further clarified the intent of this procedure in their letter of reply d:ted 3zember 3, 1972, to the initial viciatien, bv includin: installel, but not energized equipment under the surveillance recuirerents.
Surraft.1cmce racorde,ddrees en2r21 cleanliness and temperature conditions of the electrical equiprent storage ares, but do not list the ecuipr.ent subject to this surveillance, nor its location, pre-cluding a determination that all such equipcent is properly maintained.

surveillance, and the location of the equipment, was not available in the organization responsible for this function.
e.
United Engineers and Constructors Procedures ECP-6 and ECP-10 both require notification of the field supervisor, Quality Control, prior to the installation of engineered safeguards equipment.
Four engineered i
safeguards motors were installed without the written notification described in Metropolitan Edison's reply dated November'3, 1973 to the initial violation.
f.
United Engineers and Constructors Procedure ECP-6 further requires that the engineered safeguards motor j
shafts be rotated monthly.
Twelve engineered safeguards motors for Unit 1 were identified which did not have the motor shafts rotated within the specified frequency.
Six of these 12 motors show no disposition regarding rotation since their receipt. Approximately 15 motors, 5 of which were subsequently identified as engineered safeguards motors for Unit 2, had been stored in a separate warehouse with no record of motor shaft rotation since their receipt.
Corrective action had not been
('J effected between October 6, 1972, when this deficiency k
was directed to your attention, and March 28, 1973.
