Licensee Action on Previous Inspection Findings (Closed)
Violation (400-403/81-20-01)
Improper Testing of Concrete Cylinders.
During the testing of concrete cylinders, the rate of loading was applied in the range of 125 to 175 psi per second instead of the required loading rate'f 20-50 psi per second.
The inspector examined the licensees response dated November 20, 1981 and implementa-tion of that response.
The flow control valve affecting the rate of loading has been replaced, the compressive testing machine recalibrated and the technician in question has been recertified.
Observation of cylinder testing by the NRC inspector showed that testing is being done in accordance with licensee requirements.

(Closed)
Violation (400-403/81-18-02)
- Control of ESM Gate Guides.
'Safety-related and non-safety-related screen guides were stored together and were not adequately marked so as to distinguish between safety-related and non-safety-related screen guides.
The inspector

e examined the licensee response dated December 10, 1981, and imple-
.mentati.on of that response.
Examination of vendor and manufacturer's data showed that both screen guides are manufactured identically and meet seismic design criteria.

Unresolved Item (400-403/81-18-01)
- Epoxy Grout Radiation Tolerance.
Documentation was not available at the site during the NRC inspection performed on September 8-11, 1981 to verify that required radiation tolerance tests were made on Concresive 1411 epoxy grout.
Examination of documentation furnished to the inspector during this inspection showe'd that Design Base Accident tests with simulated LOCA conditions and irradiation tests were performed and that no defects were exhibited by the tested material.
This item is closed.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection The inspector examined the following areas:
a.
Soils and concrete testing laboratory b.
Seismic monitoring program, including all quarterly reports to date.
No earthquakes have been detected in the plant site area.
c.
Main and west auxiliary dam and results of periodic inspection.
Some seepage was observed along the downstream toe of the embankment adja-cent to the left abutment,.
This was reported in the last licensee periodic inspection report and is being monitored by responsible licensee engineers.
6.
Containment (Structural Concrete III) Observation of Work and Work Activi-ties, Unit, 1, 2, 3 and 4 The inspector observedpartial placement of pour numbers ISXW241-006
007 and ISSL-238-008 in the Emergency Service Water Intake structure, pour number ICBEF 305-001 in the Unit One Containment building and pour number ACSL 305-003 in the Auxiliary-Common building.
Acceptance criteria examined by the inspector appear in the following documents:
a.
PSAR Section 5, b.
EBASCO Specification CAR-SH-CH-6 c.
CP&L Procedures CQC-13, CQA-6, WP-5, TP-15, and QCI-13.3 Forms were tight, clean and level.
Rebar was properly installed and clean.
Placement activities pertaining to delivery time, free fall, flow distance, layer thickness and consolidation conformed to specifications.
Concrete placement activities were continuously monitored by Construction and QA

Examination of batch tickets indicated that the specified design mix was being delivered.
Samples of plastic concrete were obtained from the pumpline
,discharge and t'ested in accordance with specification requirements.
Test results indicated that plastic concrete being placed met requirements for slump, air content, and temperature.
Observation of controls on field curing of concrete test cylinders disclosed the following violation..
Specification CAR-SH-CH-6
"Concrete" requires that field cured test cylinders be controlled in accordance with ASTH C-31.
ASTM C-31 specifies that field cured test cylinders are to be stored under conditions that maintain the temperature adjacent to the cylinders in a.
range of 60 to 80 degrees fahrenheit for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after molding of the cylinders.
Contrary to the requirements of specification CAR-SH-CH-6, test cylinders from pour numbers ISX'Ir/241-006 and 007, AC SL 305-003, and I CB EF 305-001 were observed being stored at temperatures less than 60 degrees fahrenheit during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after molding.
Failure to control the curing temperature on field cured test cylinders was identified to the licensee as violation 400-403/81-24-0 (
