2.0 Backaround i
A number of EQ violations were identified at Calvert Cliff Units 1 & 2 following a region based inspection in February and March of 1987. These deficiencies came after several NRC EQ team inspections that identified rignifican. '"9 equirmnt deficiencies at Calvert Cliffs in 1984 and 1985.
As a resuls of these findings, the licensee developed a comprehensive program to inspect in detail the installed configuration of 10 CFR 50.49 electrical equipment in Unit 1 (shutdown on April 1,1987) and Unit 2
'
(down for refueling outage). All identified discrepancies vere resolved.
,
A task force of Design Engineers, personnel with licensed operator
'
experience and contract consultants reviewed the discrepancies.
Licensee-
!
interim and long-term corrective actions were planned to improve the EQ l
program.
For the short-term, interim methods were established to provide clear communication of EQ activities to field craft personnel and to provide additional reviews by qualified EQ reviewers.
Long-term corrective actions included:
an overall EQ Program Manager; revised EQ qualification
!
maintenance requirement sheets which clearly provide EQ maintenance requirements; and an independent review of the EQ program.

3.0 EQ Program
'l Licensee management has led the effort to develop a comprehensive
.
I program to inspect 10 CFR 50.49 electrical equipment. The QA organization l
has provided an independent review of the EQ Program to ensure complete and proper documentation of inspections and subsequent reinspection following corrective maintenance of the discrepancies.
Program controls have been established-(CCI-208E) of EQ maintenance requirements (E-406)-
for craftsmen to ensure work is completed as directed. The scope of the revised EQ program encompasses such items as procurement activities, replacement parts, disposition of EQ deviations, modifications to EQ equipment and engineering reviews of environmentally qualified equipment.
To ensure a clear line of responsibility and authority, a Principal Engineer from the Plant and Project Engineering Section was named EQ Program Manager, responsible for the establishment and implementation of l
the EQ program. An EQ Systems Engineer, responsible to the EQ Program Manager, has been assigned to resolve day-to-day problems generated by the Qualification Maintenance Program.
New paragraphs in CCI-208E denote restrictions on contract personnel and l
Vendor Representatives regarding EQ maintenance with examples of what.
l does and does not constitute EQ maintenance.
Verification of the licensee revised EQ Program was accomplished by review of the following documents and visual inspection of the following installations.

Training requirements for EQ technicians have been clarified and the required courses listed.
Based on the above review and a sample verifica-tion of installed EQ equipment, the NRC inspectors determined that the licensee has established procedures that ensure qualification of electrical equipment within the scope of 10 CFR 50.49 is maintained on a continuing basis.
4.0 Status of Previously Identified items (Closed) Unresolved Item No. 317/85-03-04 pertaining to the flow
instability problem that was observed during tests of a motor-driven l
Auxiliary Feedwater Pump (AFW) at low steam generator pressures.
The problem was attributed to cycling of the automatic recirculation
(ARC) valve and a high flow capacity (CV). This problem was
'
partially corrected on Unit 2 by changing the trim on the control valve and disabling the ARC.
l Modification and Testing (TSP-188) was conducted on Unit I regarding the AFW system flow instability in Ap-11 1985 to determine the acceptability of an ARC valve modification and the required trim on the flow control valves for both Units 1 and 2.
A Facility Change Request (FCR) 84-1094 was completed in October 1986 for Unit 1 and in April 1987 for Unit 2.
This FCR authorized permanent defeat of the. ARC feature on both units ARC valves and a further reduction in trim on the motor train flow control valves 1/2-CV-4525/4535.

labeling of Breakers in Motor Control Console Nos. 104 and 114, the
!
Battery Disconnect Switch No 95-1203 and ECCS Pump Room No. 22.

The licensee plans to install the labels by March 30, 1989.
This item is closed.
(Closed) Violation Nos. 317/85-20-03 and 318/85-20-03 pertaining to
licensee failure to follow procedures (QAP-7) requiring that changes to control documents be controlled by initialing and recording the
,
date of change by the individual making the change.
The inspectors examined specifications, instructions and revised EQ files noting that where changes were made to the control document, the changes were lined out and properly initialed and dated.
In addition, personnel were alerted to the requirement in QAP-7 that changes to controlled documents be lined out, initialed and dated by the individual making the change.
This item is closed.
(Closed) Unresolved Item Nos. 317/85-22-05 and 318/85-20-05
pertaining to adequacy of EQ training.
The inspector reviewed
'
licensee training memorandum nos. 86-M-22, 87-M-15, 87-M-14, 87-M-22, 87-M-35 and thirty-one separate class rosters documenting EQ training completed in 1988.
The inspector noted that various disciplines attended the training which consisted of lectures and
" hands on" exercises.
The inspector also attended the licensee's Introductory EQ Training session for systems engineers.
The training session was given by the EQ Program Manager and lasted approximately thirty minutes.
Class participation was good.
The twelve systems engineers in
,
l attendance appeared knowledgeable in the area of EQ as evidenced by
'
the type of questions asked and responses to the instructor.
The licensee's training provides a basic presentation of the EQ program to ensure consistency in the performance of associated activities.
This item is closed.
(Closed) Unresolved Item No. 317/86-19-02 pertaining to an
unqualified wrap-around splice, identif ted in December 24, 1986.
The licensee replaced the unqualified splice immediately after it was found with a qualified Raychem splice.
However, the identification of other similar deficiencies was not determined until after the NRC inspection of March 23-27, 1987.
Licensee short-term /lo'ng-term corrective action to resolve the problem was determined to be adequate.
This item is closed.
