IE Bulletin 79-01B Installation Verification The inspector on October 27-29, 1980 performed an installation verification of components of th9 Condensate and Feedwater System, and Compressed Air System.
The installaw;on verification consisted of an inspection of components located inside primary containment on Unit 1 and components located outside primary containment on Unit 2.
The inspection was performed in accordance with IE inspection requirements entitled " Inspection Requirements for Verifying Reactor Licensee Responses to IE Bulletin 79-018."
3.

The inspector performed installation verification of the following components:
(1) Equipment No.
Serial No.
Penatration No.
ILT-1113A 7004A5539A118 1 ZEE 4 ILT-ill38 7004A5539A119 1 ZEE 9 ILT-1113C 7004A5539A120 1ZWE3 ILT-1113D 7004A5539A121 1ZWE9 (2) Fischer and Porter, model 13D2495KBNS, transmitters, located above the 45 ft. elevation.
(3) Amphenol Sams penetrations.
Terminal strips within penetration connection boxes.
No drain holes in the connection boxes.
(4) The physical configuration from transmitters to penetrations consists of the following:
(a) Transmitter to Anaconda flexible conduit.
(b) Flexible conduit to condulets.
(c) Condulets to rigid conduit.
(d) Rigid conduit to pull boxes to trays or rigid conduit to trays.
(e) Trays to penetration connection boxes.
(f) Transmitters to flexible conduit and rigid conduit were not sealed.
(g) Terminations in 2 transmitters were by terminal strips.
Terminations for 2 transmitters were in transmitter terminal strips to condulet with ring lugs, screws and nuts, and electrician's tap.
'
c.
During the inspection, the inspector identified the following compo-nents that were installed but were not identified in the May 23, 1980 submittal:
(1) Anaconda flexible conduit
!
(2) Rigid conduit (3) Penetration connection boxes t
(4) Cable trays l

The apparent omission of data on these items in the submittal is considered unresolved pending NRC review of final licensee submittal of IEB 79-01B.
(50-317/80-20-1)
d.
During the inspection, the inspector observed that the penetration connection boxes have not been maintained to agree with the "As Built" design drawing, No. 205-10096.
The connection box covers had missing screws, the cork gasket material had deteriorated, and cables entering the top of the connection box were not properly sealed.
This would indicate that the licensee's maintenance practices in this area are inadequate.
This item is considered unresolved pending NRC review of licensee corrective action.
(50-317/80-20-2)
e.
The transmitter physical interface with the conduit and cable described in paragraph 3 b (4) above, does not appear to meet the environmental qualifications.because of improper termination and sealant.
This item is considered unresolved pending NRC review of licensee corrective action.
(50-317/80-20-3)
4.
Compressed Air System - Unit 1 a.
The following documentation was reviewed by the inspector:
(1) Trays and Conduit Drawing Containment Unit 1, E-290, Elevation 27 ft.
b.
The inspector performed installation verification of the following components:
(1) Equipment No.
Serial No.
Penetration No.
150-2085 04124J lZEC4 (2) Asco solenoid valve, model No. NP 8320A195V, located at Elevation 27 ft.
(3) Amphenol Sams penetration.
Terminal strips within penetration connection box.
No drain hole in the connection box.
,
(4) The physical configuration from the solenoid valve to the pen" ion consisted of the following:
(a) Solenoid valve to Anaconda flexible conduit.
l (b) Flexible conduit to condulet.

(d) Rigid conduit to tray.
(e) Tray to Penetration.
(f) Terminations for the solenoid valve in the condulet are ring lugs, screws and nuts, and electrician's tape. Terminations in the terminal box are terminal strips.
(g) Solenoid valve to flexible conduit and terminal box are not sealed.
c.
The Compressed Air System has physical installations identical to those addressed in the Condensate and Feedwater System, paragraphs 3.c, d and e above.
This is considered part of the unresolved items above.

Containment Isolation Valve Position Indication Baltimore Gas and Electric Company submittal, dated May 23, 1980 did not include containment isolation valve position indication for engineered safeguards.
The position switches for this function are required to meet environmental qualifications.
The apparent omission of data on this item in the submittal is considered unresolved pending NRC review of final licensee submittal of IEB 79-018.

7.
Steam Generator Level Transmitter The inspector examined steam generator No. 11 safety-related instrumentation, level transmitter ILT-lll3c and found the transmitter isolated from the instrument process lines and temporary tygon tubing connected to the transmitter drain line.
This arrangement was not in agreement with "As-Built" design drawing M-5728, Pevision 3.
The Calvert Cliffs Te'hnical Specifications, Section 6.8.1, states, in part, " Written procedures should be established, implemented and maintained covering the activities referenced below.
(a) The applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33, November,1972.
(b) Refueling operations...".
QAP 14, Section 5.1, Control of Maintenance, states, in part, " Maintenance that can affect the performance of Safety-Related structures, systems, or components must be properly pre-planned and performed in accordance with written Procedures, (Maintenance Procedures, Functional Test Procedures),
documented instructions or Maintenance Requests.
Such maintenance includes Preventive Maintenance, Corrective Maintenance and modifications...".
Contrary to the above, this activity was performed without written Maintenance Procedures or a Maintenance Request.
The ifcensee was informed that this was in noncompliance with 10 CFR 50, Appendix B, Criterion V, which states, in part, " Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circum-stances and... shall include appropriate quantitiative or qualitative acceptance criteria...".
