Gentlemen:
I This letter relates to the discussions Mr. Kelley of this office held with Messrs. Bennett and Froats during and at the conclusion of the inspection conducted on February 9 through 12, 1971, regarding the construction activities authorized by AEC Co"nstruction Permit No. CPPR-51 for the Crystal River facility, e
W As noted during the discussions, apparent deficiene s were identified in-
+
volving items which r: not in conformance with Appendix B to 10 CFR 50 of the AEC Regulat. ions, " Quality Assurance Criteria for Nuclear Power Plants."
s eJ ff These itenp are as follows:
. The Code of Federal Regulations, 10 CFR Part 50, Appendix B, QA
/
/
Cr rien IX, requires that measures be established to assure that
[v ng, heat treati nondestructive special p esses inc u testing are contr ed and accomplished by qualified personnel using
/
qualified procedure in a ordance with applicable codes, standards, specifications, crite d o er special requirements. Chicago Bridge and Imn Company (CB&I) Halogen Test Procedure HLP-1L requires th chase channel over the butt v of the containment liner om plates, knuckle section and toriconical see on be pres-
/
'surized to 5 psig of freon and then pressurized to 63.3 psig with air.

Contrary to the above, the leak chase systems are being pressurized with freon to appro g,(p ing a 100 psigy pres-surizing the' system to 63.3 psig with a/r.
i Go actice for accurate s
measurement requires'that. a gage b& used at mid-range of its full dial
'7 capaqity and a 10 psig capacity' gage should have been used to measure N
the5psigofpeon. CB&I took the positioyhat the hystersis of the 100psigIa was on the conservative side at t sig and FPC in-
.s structed CB&I to increase the freon pressure to 8 psig.
f The Code of Federal Regulations,10 CFR Part 50, Appendix B, QA Criterion V, requires that activities affecting quality shall be pre-f scribed by documented instructions, procedures or drawings, of a type o
approprie.te to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Instructions, proce-l dures, or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been accanplished.
Con %y to the above the toriconical section of the containment liner g
was erected by CB&I with the top edge above and below the elevation 103'-0" stated on the erection drawings. The erection of the cylin-drical courses continued after tri::: ming that portion of the toriconical section above the 103'-0" elevation leaving two gaps 2C0* of the cir-Special cumference with a height of up to two inches. CB&I/ Repair Procedure SRP-lL states that a six-inch-vide plate of identical material to the
\\
a liner plate vill be inserted into the area where the toriconical section 9

was below the 103'-0" elevation and is cut to elevation 102'-6".
The procedure does not include an engineering analysis of the distortion that caused the tericonical section to be below the required 103'-0" A
elevation.
Please provide us, within 30 days, with your comments concerning these items and any steps which have been or will be taken to correct them and to mini-mize recurrences. Your reply should emphasize, in particular, any appropriate changes that have been or will be made to improve the effectiveness of your quality assurance program.
Should you have any questions concerning the matters discussed in this letter, g
m you may connunicate directly with this office.

L DIVISION OF COMPLIANCE M0tmILY REPORT FOR FEBRUARY 1971
.a
~ ~ ~ - -....
Florida Power Corporation (Crystal River 3) - Co inspection was conducted on Jebruary 9-12 to review selected quality con-trol records, observe erection of the containment liner and to spot check implementation of the QA/QC program for electrical and instrumentation systems.
During the erection of the contain-ment liner the upper course of the bottom section of the liner dome was not held securely enough, resulting in two gaps of up to two inches between this section and the first course of the cylindrical section of the liner.
The gap on the east side ex-tends 40% of the circumference and the gap on the west side ex-(n) tends 23% of the circumference.
CB&I has developed a repair c
\\_/,
procedure.
