Diesel Status Reference:
(a) R0 Bulletin 74-16 (b) 77-10-02 Retest Requirements (c) Colt Industries letter dated February 17, 1977 The licensee has issued an approved Special Procedure 51.19 Diesel-Generator Initial Operational Test. The content of the procedure addressed the following areas.
Vendor Field Msdification and Inspection of Unit 2 Diesel Generator Units The procedure includes the following work items:
Inspection of piston insert for machining error. (Identified in a.
Reference (a))
b.
Fuel Header Crossover connection replacement.
c.
Replacement of cam rollers.

Reactor Coolant System Hydrostatic Test Reference: TP 200/4, MTX 147.5 (Draft Procedure)
The inspector reviewed the " Draft" of procedure TP 200/4, MTX 147.5, Reactor Coolant System Hydro Test.
The procedure addressed the guidelines of USAS B 31.7-1963 under Paragraph 1-737.
,
The areas addressed in this procedure included communications during testing, designation of " official" and backup gauges, specifications for reactor coolant versus metal temperatures, established pre-requisites and temporary jumper installation.
The inspector identified the folicwing areas of concern:
The range _ of official and backup gauges was inconsistent with the code.
The requirements for jumpers and attachments to systems required for
testing did not specify pressure ratings of the equipment.
The criteria for minimum temoerature for test media and corresponding vessel temperatures was not established.
The access list should include NRC inspectors access to official hydro gauges.
A limiting ntanber of RC Pump starts within certain time frames was not included in the procedure.
A reference to the Thermal Expansion Test readouts during hydrostati:
test was not documented.
The licensee stated that the above concerns would be addressed in the approved procedure. This is Open Item 77-14-01.

Preoperational Test Procedure Review TP 330/4. MTX 38.6, Intecrated CRD System Test The inspector raviewed the approved procedure for ANSI 18.1 conformance
-
and technical content. The procedure cddresscs:
_
Auxiliary and Regulated Power Supplies;
-
Accuracy of Relative and Absolute position Indication circuits;
-
Operation of individual and group control;
-
Interlocks and alarms associated with CRDs; and.
-
Rod speed in the Run mode for each regulating power supply.
-
The inspector's concerns were resolved.
No inadequacies were identified.
5.
HFT Procedure 600/17, Control Rod Drive Operational Test The inspector reviewed the licensee's approved procedure 600/17, CRD Operational Test, which addresses the daily exercise of CRDMs and flushing of CROM buffer cylinders.
No inadequacies were identified.
6.
Unusual Occurrence - Construction Abnomaly The licensee reported to the inspector an occurrence that will be re- ~
ported under 10 CFR 50.55e. The construction of Auxiliary Building Stairwell, enclosed staircase and block wall around WDS-T-2 have been constructed not to the plan. An investigation by the licensee is presently underway. This item is unresolved.
(77-14-03)
7.
Plant Tour a.
General The inspector p<rformed three tours of work areas outside of normal working hours. The tours covered activities in the control room, main feed pump piping realignment, diesel generator room venti-lation modification, radwaste storage areas, ion exchange areas and makeup pump rooms, steam generator and pressurizer creas, and the 480 V notor control center.

The turbine building areas were adequately cleaned.
One area
-
indicated the need for further attention to housekeeping; the area adjacent to the motor control center had an accumulation of decris (unpacked cartons, workers lunch refuse) and repre-sented a potential fire hazard to safety-related equipment.
The licensee stated that clean up personnel nonnally attend
.
all areas on a two to three day cycle. The inspector stated that the amount of attention given to housekeeping should be reviewad for the need of increasing efforts in that area.
b.
Diesel Generator Room - Failure to Maintain Closures
-
Reference:
(1) Quality Control Procedure 27-2, Prevention of Foreign Material Entry and Control of Tools (2) FCR-2340.lR1, Diesel Generator Building Sheet Metal Work The licensee is presently modifying the vent'ilation system in the Diesel Cenerator Buildings. The modification includes the installation of a new run of sheet steel ventilation ducting, taking a direct suction off the left and right generator upper covers. FCR #2340.1 documents the requirements for the controls during the modifications in Section 3.9, Cleaning and Cleanliness, requirements per AE Procedures and Section 3.13, Contractor Quality Control Requirements.
(
During the inspector's tour of the working area in D.G. Room
- 2, on April 7,1977, at 0630 hours0.00729 days <br />0.175 hours <br />0.00104 weeks <br />2.39715e-4 months <br />, an opening to the gener-ator to which a sheet metal transition picce will be attached, was found unprotected.
The inspector observed metal chips in the generator stator area.
The licensee was informed of findings and did examine the area. The licensee stated that both generators would be cleaned prior to operation.
(The ins during a previous inspection)pector had noted proper closure
.
This failure to maintain closures of safety-related equipment
'
per QC 27-2 and 10 CFR 50, Appendix B, Criteria XIII Rev. 2 is considered an Item of Noncompliance categorized as a Deficiency.

Previously Identified Unresolved Items The following previously identified unresolved items are resolved:
a.
77-01-02 - Cleanliness of Air Systers
~
The inspector witnessed the sampling of certain terminals of the instrument air system.
These sample points were deter-mined at the time of testing by the inspector.
Observations by the inspector confirmed the licensce's cleanliness requirements in the area of water and oil content of sample points. All sampled areas were satisfar;ory.
This item is resolved.
b.
76-07-01 - TP 401/3, Station Batteries Charge and Discharge Test The licensee has revised the test procedure to include pre-cautions for personnel entry into the battery rooms on an indication of a high hydrogen concentration in Section 6.5 of the procedure and Section 8 documents the use of warning signs.
This item is resolved.
c.
Pressurizer Relief Valve Settings
-
Reference:
Inspection 50-320/76-03. (Detail 13)
I The licensee has scheduled the testing of pressurizer relief valves RC-R-1A and RC-R-1B.
The testing will be performed per approved Work Request Procedure (April 6,1977) which in-corporates the standard administrative fonnat.
The method of testing will require the safety valve bodies and the test gas medium to be at specified temperature plateaus that will approach normal ambient conditions. The inspector identified no inadequacies in the review of the procedure.
The licensee stated that, prior to testing, NRC Region I, will be notified.
This test scheduling resolves the referenced unresolved item.
