I & E Letter to YAEC, dated July 16, 1981 I & E Inspection Report 50-29/81-06
Dear Sle:
Subject:
Response to Inspection Reference is made to I & E Inspection No. 50-29/81-06, which was conducted by Messrs.
T. Foley and A. A. Varela, of your office, on April 1 - May 30, 1981, at the Yankee Nuclear Power Station (Yankee Rowe) in Howe, Massachusetts. The report made subsequent to that inspection identified two items wnich apparently were not conducted in full compliance with NRC requirements.
In accordance with Section 2.201 of the NRC's " Rules and Practices", Part 2 Title 10 Code of Federal Regulations, we hereby submit the following iformation.
Alleged Violation Technical Specification 6.12.1 Paragraph 20.203, " Caution Signs, Labels, Signals, and Controls", states that, "In lieu of the " control device" or
" alarm signal" required by Paragraph 20.203(c)(2), each high radiation area in wnich the intensity of radiation is 1000 mrem /hr or less shall be barricaded and conspicuously posted as a high radiation area and entrance thereto shall be controlled by requiring issuance of a Radiation Work Permit.
An individual or group of individuals permitted to enter such areas shall be provided with one or more of the following:
A radiation monitoring device which continuously indicates the radiation a.
dose rate in the area.
b.
A radiation monitoring device which continuously integrates the radiation dose rate in the area and alarms when a preset integrated dose is received. Entry into sucn areas with this monitoring device may be made after the dose rate level in the area have been established and personnel have been made knowledgeable of them.
8203110214 820302 PDR ADOCK 05000029 O
2 c.
A health physics qualified individual (i.e., qualified in radiation protection procedures) with radiation dose rate monitoring device wno is responsible for providing positive control over the activities within the area and wno will perform radiation surveillance frequency will be established by the Plant Health Pnysicist.
Tne above procedure anall also apply to each high radiation area in which the intensity of radiation is greater than 1000 mrem /hr.
In addition, locked doors shall be provided to prevent unauthorized entry into sucn areas and the key shall be maintained under tne administrative control of the shift supervisor on duty and/or the Plant Health Physicist."
Contrary to the above, on May 14, 1981, the vicinity of the Main Coolant isolation Valve Stem Leax-Off drain line, (located in the Vapor Container) an area accessible to personnel having doses rate in excess of 1000 millirem per hour, was not provided with lock coors. Actual measured dose rates revealed 12000 millirem per nour at contact and 1200 millirem per hour, general area.
No other controls were established to prevent unauthorized entry to the area.
Hesponse Corrective Steps Taken and Results Achieved Upon notification of tne violation the area was hmaediately reserveyed and shielding was installed to reduce the levels of radiation to less than 1000 1
mrem /nr. Health Pnysics personnel were reinstructed to shield "not spots" or restrict personnel access to tne area, as applicable.
Corrective Steps Taken to Avoid Further Violations In the future, emphasis will be placed on conducting surveys of lines and components in all areas to locate areas of high radiation and to provide shielding or restrict access to the area as required.
Date Wnen Full Compliance was Achieved Full compliance was achieved on May 14, 1961.
Alleged Violation 10 CFR 50, Appendix B, Criteria V, states in part, that, " Activities affecting quality snall be prescribed by documented instructions, procedures, or drawings...and shall be accomplished in accordance with these instructions, procedures or orawings..."
Yankee Atomic Electric drawing number SPD-0006-CF-1002, hevision 6A and Mercury Corporation Specification SP-N49855-703 require cement grout to satis!Y tne specified compressive strength of 4.000 psi.
Contrary to the above, during April 1981, the grout material, useo around the ins talled rock ancnors in the reactor column bases was not tested to show compliance with the minimum compressive strength required by Yankee Atomic drawing numoer SPD-0006-CF-1002, Revision 6A and Mercury Corporation Specification SP-N49855-703
W 3
Hesponse de feel that the alleged Item of Noncompliance is incorrect and we, tnerefore, request that the Item of Noncompliance be withdrawn.
We case tais upon tne following information:
1.
Tne Will-X cement grout is a proprietary item of Williams Rockbolt Company.
2.
The manufacturer's instructions addressed the method of mixing and curing the grout so as to provide a cunpressive strength of 4000 psi.
These iratructiona were adnered to during the application of the cement grout.
3 A Certificate of Compliance was provided by the vendor stating that the product snipped was what was ordered and therefore will perform as intended.
4.
The grout was used only to fill the vola around the installed rock anchors and was not required to provide any additional support based on tne analysis perforcea.
We trust tnis information is satisfactory, however, should you desire additional luformation please feel free to contact us.
Very truly yours, YANKEE ATOMIC ELECTRIC COMPANY
