MP&L Nondestructive Examination Standard for Radiography (M-RT-XG-2, Rev. 1)

During the inspector's review of MP&L's radiographic procedure M-RT-XG-2, Rev. 1, the following administrative errors were noted:

'

,

(1) The scope of the document (paragraph 1.2) identified that this l standard was written to comply with the ASME B&PV Code,Section V,

'

Article 2, 1974 Edition including Addenda through Summer 197 The ISI program requirements for radiographic examination is the l

ASME B&PV Code,Section V and XI Article 2, 1977 Edition including Addenda through Summer 1979, however, the inspectors review of the procedure did not identify any technical requirement that would not meet the 1977 Code. The licensee should update the scope of the document to include the 1974 Construction Code and the 1977 ISI 10 year interval Code prior to its use in the progra (2) Paragraph 3.0, entitled, " Equipment, Materials and Personnel,"

should describe the method used to determine actual effective source size. Attachment 1 (Radiographic-Technique Sheet), depicts the actual source size being derived from a formula. However, the radiographic procedure does not identify the values to be used in

,

the formula.

. (3) Paragraph 4.6.2 has a typographical error that changed the acceptance criteria for geometrical unsharpness from .070 inch to

.70 inch for material thicker than 4 inches. A Boiling Water Reactor like Grand Gulf, however, does not have materials thicker than 4 inches with the exception of some portions of the reactor

vessel.

e Inservice Inspection - Observation of Work and Work Activities (73753)

(Unit 1)

The inspector observed the ISI activities described below to determine whether these activities were being performed in accordance with regulatory requirements and licensee procedure See paragraph 5 above for the

applicable cod Examiner Qualification ,

.

The inspector reviewed the qualification documentation for the below

'

listed examiners in the following areas: employer's name; person certified; activity qualified to perf;.n; effective period of certifi-i cation; signature of employer's designated representatives; basis used for certification; and annual visual acuity, color vision examination and periodic recertification.

] examination of this vessel weld was performed with an automated remote ultrasonic system which presents the data in a digitize for This system is normally referred to as the GE Blue Boy System. The name has

been derived from the enclosure that houses the system. The six l

channel calibrations were compared with the requirements of the

applicable procedure and code as described in paragraph b. abov Within the areas examined, no violation or deviations was identifie . Inservice Inspection, Data Review and Evaluation, Unit 1 (73755) l

~

The inspector reviewed UT data which included computer disc and VCR tapes

! that had been evaluated by GE examiner However, this data was not j considered completed data since GE's evaluation required in many situations that ~ supplemental examinations be performed. The inspector reviewed the j data to ascertain whether the methods, techniques and extent of the examina-

{- tion complied with the ISI plan and applicable NDE procedures; findings were

! properly evaluated by qualified personnel; and programmatic deviations were recorded as required. Records for the following welds were reviewed:
